Description

COMPONENT PROTECTIVE OVERMOLDING USING PROTECTIVE

EXTERNAL COATINGS FIELD

The present invention relates generally to electrical and electronic hardware, computer software, wired and wireless network communications, and computing devices. More specifically, techniques for component protective overmolding using protective external coatings are described.

BACKGROUND

With the advent of greater computing capabilities in smaller mobile form factors and an increasing number of applications (i.e., computer and Internet software or programs) for different uses, consumers (i.e., users) have access to large amounts of data, personal or otherwise. Information and data are often readily available, but poorly captured using conventional data capture devices.

Conventional devices typically lack capabilities that can record, store, analyze, communicate, or use data in a contextually-meaningful, comprehensive, and efficient manner. Further, conventional solutions are often limited to specific individual purposes or uses, demanding that users invest in multiple devices in order to perform different activities (e.g., a sports watch for tracking time and distance, a GPS receiver for monitoring a hike or run, a cyclometer for gathering cycling data, and others). Although a wide range of data and information is available, conventional devices and applications generally fail to provide effective solutions that comprehensively capture data for a given user across numerous disparate activities.

Some conventional solutions combine a small number of discrete functions. Functionality for data capture, processing, storage, or communication in conventional devices such as a watch or timer with a heart rate monitor or global positioning system ("GPS") receiver are available, but are expensive to manufacture and typically require purchasing multiple, expensive devices. Other conventional solutions for combining data capture facilities often present numerous design and manufacturing problems such as size specifications, materials requirements, lowered tolerances for defects such as pits or holes in coverings for water-resistant or waterproof devices, unreliability, higher failure rates, increased manufacturing time, and expense. Subsequently, conventional devices such as fitness watches, heart rate monitors, GPS-enabled fitness monitors, health monitors (e.g., diabetic blood sugar testing units), digital voice recorders, pedometers, altimeters, and other conventional data capture devices are generally manufactured for conditions that occur in a single or small groupings of activities and, subsequently, are limited in terms of commercial appeal to consumers.

Generally, if the number of data inputs accessible by conventional data capture devices increases, there is a corresponding rise in design and manufacturing requirements and device size that results in significant consumer expense and/or decreased consumer appeal, which eventually becomes prohibitive to both investment and commercialization. Still further, conventional manufacturing techniques are often limited and ineffective at meeting increased requirements to protect sensitive hardware, circuitry, and other components that are susceptible to damage, but which are required to perform various data capture activities. As a conventional example, sensitive electronic components such as printed circuit board assemblies ("PCBA"), sensors, and computer memory (hereafter "memory") can be significantly damaged or destroyed during manufacturing processes where protective overmoldings or layers of material occurs using techniques such as injection molding, cold molding, and others. Damaged or destroyed items subsequently raises the cost of goods sold and can deter not only investment and commercialization, but also innovation in data capture and analysis technologies, which are highly compelling fields of opportunity.

Thus, what is needed is a solution for efficiently manufacturing devices without the limitations of conventional techniques.

DETAILED DESCRIPTION

Various embodiments or examples may be implemented in numerous ways, including as a system, a process, an apparatus, a user interface, or a series of program instructions on a computer readable medium such as a computer readable storage medium or a computer network where the program instructions are sent over optical, electronic, or wireless communication links. In general, operations of disclosed processes may be performed in an arbitrary order, unless otherwise provided in the claims. A detailed description of one or more examples is provided below along with accompanying figures. The detailed description is provided in connection with such examples, but is not limited to any particular example. The scope is limited only by the claims and numerous alternatives, modifications, and equivalents are encompassed. Numerous specific details are set forth in the following description in order to provide a thorough understanding. These details are provided for the purpose of example and the described techniques may be practiced according to the claims without some or all of these specific details. For clarity, technical material that is known in the technical fields related to the examples has not been described in detail to avoid unnecessarily obscuring the description.

FIG. 1 illustrates a cross-sectional view of an exemplary process for providing protective material in data-capable strapband overmolding. Here, device 100 includes framework 102, elements 104-106, and covering 108. In some examples, framework 102 may be referred to interchangeably as a substrate, wafer, board (printed, unprinted, or otherwise), or other surface upon which elements 104- 106 may be mounted, placed, or otherwise fixed. The type and configuration of elements may be varied and are not limited to any given type of electrical, electronic, or mechanical component. For example, element 104 may be implemented as a microvibrator or motor configured to provide a vibratory signal for an alarm or other indicator. Element 104 may also be a printed circuit board assembly ("PCBA"), logic, processor, microprocessor, memory (e.g., solid state, RAM, ROM, DRAM, SDRAM, or others), or other computing element and is not limited to any specific type of component. Further, element 104 may be coupled electrically or electronically to element 106, which may also be an electrical, electronic, or mechanical component that can be placed on framework 102. When placed on framework 102, elements 104-106 may be fixed using various techniques, including adhesives, mechanical fixing structures (e.g., posts and holes), or others, without limitation.

As shown, covering 108 may be placed over element 104 in order to protect the latter from damage resulting from the application of subsequent layers, coverings, moldings, or other protective material, regardless of environmental conditions (e.g., temperature, pressure, thickness, and others). As shown, element 104 is covered by covering 108 and element 106 is uncovered. However, other protective materials may be used to cover element 106. In still other examples, protective materials such as covering 108 may not be used if elements 104 or 106 are manufactured to resist the formation, deposit, layering, or covering of other protective materials at various temperatures, pressures, or other atmospheric conditions. In other examples, device 100 and the above-described elements may be varied and are not limited to those shown and described.

FIG. 2 illustrates another cross-sectional view of an exemplary process for providing protective material in data-capable strapband overmolding. Here, device 200 includes framework 102, elements 104-106, covering 108, syringe 202, arrows 204-206, and protective coating 208. In some examples, covering 108 and protective coating 208 may be referred to as "protective material" interchangeably and without limitation. As shown, like numbered elements shown in this drawing and others may refer to the same or a substantially similar element previously described.

In some examples, an applicator (e.g., syringe 202) may be used to selectively apply protective coating 208 to cover as a protective layer over element 106. As used herein, "selectively applying" may refer to the application, placement, positioning, formation, deposition, growth, or the like, of protective material to one, some, all, or none of any underlying elements (e.g., elements 104- 106). In some examples, "protective material" may also be used interchangeably with "protective layer," "covering," "housing," or "structure" regardless of the composition of material or matter used, without limitation. In other words, covering 108 and protective coating 208 may each be referred to as "protective material" and used to protect underlying elements (e.g., elements 104-106 (FIG. 1)) as described herein.

When the plunger of syringe 202 is depressed in the direction of arrow 204, protective coating 208 is forced through applicator tip 210 and applied as a protective layer over element 106. As an example, protective coating 208 may be applied at substantially atmospheric pressure by applying 1-2 psi of pressure to the plunger of syringe 202. When applied, protective coating 208 may be, for example, an ultraviolet ("UV") curable adhesive or other material. In other words, when protective coating 208 is applied (i.e., layered over element 106) and exposed to ultraviolet radiation (or other curing conditions) at levels similar to those found in natural sunlight or artificial light, it coalesces and hardens into a covering that prevents the underlying element (e.g., element 106) from being damaged when other protective materials or layers are applied such as those shown and described below. Exemplary types of protective coating 208 may include coatings, adhesives, gels, liquids, or any other type of material that hardens to protect, prevent, minimize, or otherwise aid in avoiding damage to a protected element. Examples of UV curable coatings include Loctite® coatings produced by Henkel & Co AG of Dusseldorf, Germany such as, for example, Loctite® 5083 curable coating. Other types of curable coatings, in addition to those that are UV curable, may be used to protect underlying elements without limitation or restriction to any given type.

In some examples, protective material such as Loctite® or others may be applied selectively to one, some, or all electrical, electronic, mechanical, or other elements. Protective coating 208 may also be applied in different environmental conditions (e.g., atmospheric pressure, under vacuum, in a molding cavity or chamber, within a deposition chamber, or the like) and is not limited to the examples shown and described. As shown, protective coating 208 has been selectively applied to element 106, but not element 104, the latter of which is being protected by covering 108. As an alternative, covering 108 may be used as protective material in the form of an enclosure or physical structure that is used to protect an underlying element. As described herein, protective coating 208 may be selectively applied by determining whether sensitive components, parts, or other elements ("elements") are susceptible to damage or destruction from subsequent processes, for example, to deposit additional protective layers, such as those described in greater detail below. In other examples, device 200 and the above-described elements may be varied in function, structure, configuration, implementation, or other aspects and are not limited to those provided.

FIG. 3 illustrates a cross-sectional view of an exemplary process for forming an inner molding in data-capable strapband overmolding. Here, device 300 includes framework 102, elements 104-106, covering 108, syringe 202, arrows 204-206, protective coating 208, mold cavity 302, nozzle 304, arrows 306-310, and inner molding 312. In some examples, framework 102 and elements 104- 106 having selectively applied protective coating 208 may be placed in mold cavity 302 where another protective layer or coating (e.g., inner molding 312) may be applied from nozzle 304 in the direction of arrows 306-310. Types of materials that may be used for inner molding 312 include plastics, thermoplastics, thermoplastic elastomers, polymers, elastomers, or any other organic or inorganic material that can molded in mold cavity 302. As shown, mold cavity 302 may be implemented using a variety of molding techniques. For example, an injection molding machine may be used to inject a thermoplastic polymer elastomer ("TPE") into mold cavity 302. When injected under temperature (e.g., 400 to 460 degrees Fahrenheit) and pressure (e.g., 200 to 600 psi, but which may be adjusted to higher or lower pressure, without limitation), inner molding 208 forms a protective layer around framework 102, elements 104-106, covering 108, protective coating 208, providing a layer of additional protective material (e.g., inner molding 312), which may completely or incompletely surround an object (e.g., framework 102). In some examples, inner molding 312 may be formed to provide a watertight or hermetic seal around framework 102 and elements 104-106. Types of materials that may be used as inner molding 312 include TPEs such as Versaflex 9545-1 as manufactured by PolyOne Corporation of McHenry, Illinois. Other types of materials such as epoxies, polymers, elastomers, thermoplastics, thermoplastic polymers, thermoplastic polymer elastomers, and others may be used to form inner molding 312, without limitation to a specific material. In other examples, device 300 and the above-described elements may be varied in function, structure, configuration, implementation, or other aspects and are not limited to those provided.

FIG. 4 illustrates another cross-sectional view of an exemplary process for forming an outer molding in data-capable strapband overmolding. Here, device 400 includes framework 102, elements 104-106, covering 108, syringe 202, arrows 204-206, protective coating 208, inner molding 312, mold cavity 402, nozzle 404, arrows 406-410, and outer molding 412. In some examples, mold cavity 402 may be the same or different from that described above in connection with FIG. 3. In other words, mold cavity 402 may be the same mold cavity as mold cavity 302, but which is used to injection mold outer molding 412. As shown, framework 102, elements 104-106, protective coating 208, and inner molding 312 are placed in mold cavity 402. Material (e.g., TPE) may be injected through nozzle 404 in the direction of arrows 406-410 into mold cavity 402 in order to form outer molding 412. Once formed, sprue or other extraneous material may be present in inner molding 312 or outer molding 412, which may be removed after device 400 is taken out of molding cavity 402. A visual inspection, in some examples, may be performed to determine if defects are present in either inner molding 312 or outer molding 412. If defects are found in outer molding 412, then removal may occur and a new outer molding may be formed using mold cavity 402. The inspection and, if defects are found, the removal of outer molding 412 allows for higher quality moldings to be developed at a lower cost without requiring the discarding of sensitive, expensive electronics. Outer molding 412, in some examples, may also be used to provide surface ornamentation to a given object. The use of thermoplastics or TPE material may be used to form outer molding 412 and to provide material in which a surface texture, design, or pattern may be imprinted, contoured, or otherwise formed. In so doing, various types of patterns, designs, or textures may be formed of various types. For example, miniature "hills" and "valleys" may be formed in the protective material of outer molding 412 in order to produce a "denim" feel or texture to a given object. Examples of different patterns for outer molding 412 may be found in FIGs. 5A-5C, as shown by patterns 502, 512, and 522, respectively. Patterns 502, 512, and 522 are provided for purposes of illustration and are neither limiting nor restrictive with regard to the types, patterns, designs, or textures of surface ornamentation that may be applied to outer molding 412, as described herein. Protective material (e.g., TPE) injected into mold cavity 402 may be used to form these patterns. Various types of injection molding processes and equipment may be used and are not limited to any specific type, make, manufacture, model, or other specification.

Referring back to FIG. 4, the use of the described techniques allows for more precise tolerances in forming moldings that are form-fitting to various types of devices. Still further, the use of the above-described techniques also allows for relatively small devices having sensitive electronics to be subjected to harsh environmental conditions during molding processes in order to form protective layers (e.g., inner molding 312, outer molding 412) over various types of devices. As shown and described, the disclosed techniques may be used on a variety of devices, without limitation or restriction. In other examples, device 400 and the above-described elements may be varied in function, structure, configuration, implementation, or other aspects and are not limited to those provided.

FIG. 6A illustrates an exemplary process for component protective overmolding. Here, the start of process 600 includes forming a protective layer on, for example, framework 102 (FIG. 1) (602). In some examples, a protective layer may refer to protective material, layers, or covers such as protective material 108 (FIG. 2) or structures that are formed to protect underlying elements (e.g., covering 108 (FIG. 1). Examples of material that may be used to form a protective layer include UV curable materials such as those described above, including coatings, adhesives, liquids, gels, and others that cure when exposed to ultraviolet radiation in various concentrations and exposure levels without limitation. After forming a protective layer (e.g., protective coating 208), an inner molding (e.g., inner molding 312 (FIG. 3)) is formed (604). After forming an inner molding, a function test is performed to determine whether the inner molding and protective layer have damaged the underlying item (606). In some examples, a function test may be performed as part of an inspection and include applying an electrical current to an underlying electronic element to identify proper voltage or current flow or other parameters that indicate whether damage has occurred during the formation of a protective layer, an inner molding, or, in other examples, an outer molding. Inspections may be performed at various stages of the manufacturing process in order to identify defects early and reduce costs incurred with re-applying protective layers or moldings. In other examples, a function test may be performed to determine whether the inner molding has sufficiently coated desired underlying items (e.g., electrical, electronic, mechanical, or any structure or elements thereof that are being protected from damage using one or more moldings). In still further examples, the function test may be performed to determine whether the formation of an inner molding damaged underlying items that were previously protected by the formation of protective layer, the latter of which may be performed outside of a mold device or cavity (e.g., mold cavity 302 (FIG. 3) or mold cavity 402 (FIG. 4)) at room temperature and/or atmospheric conditions, including atmospheric or ambient temperatures, pressures, and humidity levels, without limitation.

In some examples, a determination is made as to whether a function test is passed or failed (608). Here, if an item having a protective layer and an inner molding fails to pass, the item is rejected and the process ends (610). Alternatively, if an item (e.g., framework 102 and elements 106-108 (FIG. 1)) fails to pass a function test due to the presence of one or more defects, the inner molding may be removed and re-applied. In other examples, the underlying item may be rejected (i.e., destroyed, recycled, or otherwise removed from a lot of items that have successfully passed a function test). If a determination is made that a function test has passed as part of an inspection, then an outer molding is formed over the inner molding and protective layer (612).

In some examples, the protective layer, inner molding, and outer molding may be selectively, partially, or completely applied to a given item. As described here, an outer molding may also be configured to completely enclose or encase an underlying item in order to protect the inner molding, the protective layer, and any elements from damage. Further, outer molding may be used to form patterns, designs, or other surface features or contours for usable, functional, or aesthetic purposes. As shown here, after an outer molding is formed, a final test is performed to determine whether defects are present or the formation of the outer molding met desired parameters (e.g., did the outer molding fully coat an item, were any underlying items damaged, and the like) (614). In some examples, a final test may also be a function test, as described above. In other examples, a final test may also evaluate an item coated with an outer molding for other purposes. If the final test is not passed, then the item may be rejected and, in some examples, the outer molding may be removed and re-applied (i.e., re-formed) (610). In other example, a failed final test may also result in the item being rejected and destroyed, recycled, or otherwise handled as unacceptable. Finally, after a final test is performed a visual inspection may be performed to determine whether an item has been covered by the formed outer molding as desired (618). In other examples, process 600 may be implemented differently in the order, function, configuration, or other aspects described and is not limited to the examples shown and described above.

FIG. 6B illustrates an alternative exemplary process for component protective overmolding. Here, process 620 beings be selectively applying protective material (e.g., protective coating 208 (FIG. 2)) to one or more elements (e.g., electrical, electronic, mechanical, structural, or others) (622). In some examples, selectively applying protective material may include manually using an applicator (e.g., syringe 202 (FIG. 2) or any other type of instrument, device, tool, or implement used to apply protective material) to deposit a layer, covering, coating, or the like over a desired element. In other examples, selectively applying may also include the application of protective material to one, some, all, or none of the elements present on a given item. In other words, selectively applying protective material may be performed uniformly or non-uniformly without limitation. Types of protective materials may include curable or non-curable materials such as those described above, including UV-curable coatings that, when exposed to ultraviolet radiation, cure. In other examples, other types of coatings may be used that, when exposed to artificial or man-made conditions, cure. Still further, other types of coatings may be used to form a protective layer (i.e., protective material) over sensitive elements that may require the combination of two or more materials, chemicals, or compounds, such as epoxies, polymers, elastomers, and the like, without limitation.

Here, after selectively applying protective material an inner molding is formed over a framework, associated elements (i.e., elements coupled to the framework), and the previously, selectively-applied protective material (624). As an example of a framework, a "strapband" or, as used herein, "band" may refer to a wearable device that is configured for various data capture, analysis, communication, and other purposes. In some examples, a band may refer to a wearable personal data capture device that, when worn, may be used to record and store various types of data associated with a given person's motion, behavior, and physical characteristics (e.g., body

temperature, salinity, blood sugar, heart rate, respiration rate, movement, and many others, without limitation). In other examples, a band may be implemented using hardware, software, and firmware, where application-specific programs may be downloaded onto a memory that is included as an element and protected using the described overmolding processes. A band may be implemented as described below in connection with FIGs. 7-9.

Referring back to FIG. 6B, an outer molding is formed over the inner molding, the framework, its elements, and the protective material (626). After the outer molding is formed, an inspection of the outer molding is performed to determine whether a defect is present (628). As used herein, an inspection may refer to any type of process (e.g., automatic, semi-automatic, manual, robotic, visual, structural, radiological, electrical, or others) that is used to determine whether a defect is present. In some examples, an inspection may include one or more function (i.e., functional) tests to determine whether a coated (i.e., item receiving protective material and protective layers or coatings) has been damaged during the layering process. If a defect (e.g., a damaged item or defective molding) is found, then the outer molding is removed (632) and formed again over the inner molding, framework, elements, and protective material (626). If no defect is found, then the process ends. Examples of materials that may be used for moldings (e.g., inner molding, outer molding) in process 620 include plastics, thermoplastics, thermoplastic elastomers, polymers, thermoplastic polymer elastomers, epoxies, alloys, metals, or any other type of organic or synthetic material, without limitation. In other examples, process 620 may be implemented differently in the order, function, configuration, or other aspects provided and is not limited to the examples shown and described above.

FIG. 6C illustrates another alternative exemplary process for component protective overmolding. Here, an alternative 2-stage process 640 for component protective overmolding may be performed. First, selective application of a securing coating over components placed on, for example, a framework, may be performed (642). As used herein, a securing coating may refer to any type of protective material, layer, cover, structure, liquid, gel, solid, or the like that is placed substantially (i.e., partially or entirely) over an item in order to prevent damage from later stages of a manufacturing process (e.g., introduction into mold cavity 302 (FIG. 3) or mold cavity 402 (FIG. 4) in which rigorous temperatures, pressures, or other environmental conditions are created in order to apply other coated materials. Further, due to the size and relatively sensitive operating, manufacturing, and performance characteristics of various electrical, electronic, mechanical, or structural features (e.g.,

microprocessors, solid state computer memories, control logic and circuitry, microvibrators, motors, motor controllers, batteries, battery modules, battery controllers, and the like), the addition of protective material can prevent inadvertent damage and increased costs occurring during the manufacturing of finished products. As an example, consumer electronics devices receiving both aesthetic and functional protective overmoldings (i.e., moldings) can be expensive to manufacture because, for each damage underlying electronic component, an entire unit must be discarded.

However, by using the described techniques to protect sensitive and expensive elements by replacing moldings as opposed to entire partially-finished items, manufacturing costs can be significantly reduced, thus increasing profit margins and incentives for individuals and enterprises to commercially invest in manufacturing devices that can advantageously capture, analyze, use, communicate (via wired or wireless data communication facilities (e.g., network interface cards (NICs), wireless radios using various types of wireless data communication protocols for short, medium, and long-range communication (e.g., Bluetooth™, ZigBee, ANT™, WiFi, WiMax, and others), and the like), or otherwise use valuable and abundant personal data. As an example of these types of devices, a strapband or band may be a wearable device that is configured to capture data such as that described above. Sensitive elements of various sizes and shapes may be protected from damage occurring during later stages of protective overmolding (i.e., application of protective layers, covers, molds, or the like) using the described techniques.

Here, after applying a securing coating, another molding may be formed over the securing coating, band, and components (e.g., elements) (644). As described here and above, the application of one or more moldings may be performed to both secure and protect underlying items (e.g., components or elements) of a finished product for various conditions such as use, weather, shock, temperature, or other environmental conditions to which finished products (e.g., band) may be subjected. In other examples, more, fewer, or different steps may be implemented as part of process 620 including, for example, a single-stage process involving the application of one or more protective layers (e.g., housings, coverings, securing coatings, coatings, moldings, or the like). The functions, operations, or processes performed during a single or multi-stage or step process may be varied, without limitation, to include more, fewer, or different types of sub-processes apart from those shown and described. Alternatively, more steps in process 620 may be implemented are not limited to any of the examples shown and described. In still other examples, process 620 may be implemented differently in the order, function, configuration, or other aspects provided and is not limited to the examples shown and described above.

FIG. 6D illustrates yet another alternative exemplary process for component protective overmolding. Here, process 650 begins by placing one or more elements on a framework (652). In some examples, the one or more elements may be placed on a part of a framework (not shown) or other support structure configured to provide a substrate or base support. Once placed, the elements are coated using a curable material (654). As an example of a curable material, Loctite® 5083 UV curable coating may be layered (i.e., deposited, poured, injected, layered, or otherwise covered) over the elements and the framework. The curable material may be comprehensively, universally, uniformly, semi-uniformly, irregularly, or selectively placed so that some elements are covered while others are left uncovered. Reasons for selectively applying the curable coating may include other elements being protected from damage during the molding process using physical structures (e.g., covering 108) and yet others being manufactured to withstand the environmental conditions (e.g., temperature ranges between 400 and 460 degrees Fahrenheit and injection nozzle pressures of 200 to 600 pounds per square inch (psi)) of molding cavity 302 (FIG. 3) or 402 (FIG. 4) without using protective material.

After securing elements to a framework using curable material (e.g., UV curable coating, which may also be replaced with other types of curable coating, without limitation or restriction to any specific type), an inspection may be performed to determine whether there are any defects, gaps, openings, or other susceptibilities that can be anticipated before applying the first or inner molding (656). After performing an inspection on the curable coating, one or more moldings may be formed over the curable material (i.e., coating), framework, and elements (658) after which an inspection may be performed to determine whether there are defects in the molding(s) (660). During the inspection, a determination is made as to whether a defect has been found in one or more moldings (662). If a defect is found, the defective molding is removed (664) and another molding may be reformed over the curable material, framework, and elements (666). By enabling a defective molding to be replaced without requiring the discard of a framework and its associated elements (e.g., electrical and electronic components such as microprocessors, processors, data storage and computer memory, sensors (e.g., accelerometers, motion/audio/light sensors, velocimeters, pedometers, altimeters, heart rate monitors, barometers, chemical/protein detectors, and others, without limitation), mechanical and structural features or functionality), substantial costs can be saved thus enabling devices to be produced at lower costs to consumers and business alike. In other examples, process 650 may be implemented differently in the order, function, configuration, or other aspects provided and is not limited to the examples shown and described above.

FIG. 7 illustrates a side view of an exemplary data-capable strapband configured to receive overmolding. Here, band 700 includes framework 702, covering 704, flexible circuit 706, covering 708, motor 710, coverings 714-724, analog audio plug 726, accessory 728, control housing 734, control 736, and flexible circuit 738. In some examples, band 700 is shown with various elements (i.e., covering 704, flexible circuit 706, covering 708, motor 710, coverings 714-724, analog audio plug 726, accessory 728, control housing 734, control 736, and flexible circuit 738) coupled to framework 702. Coverings 708, 714-724 and control housing 734 may be configured to protect various types of elements, which may be electrical, electronic, mechanical, structural, or of another type, without limitation. For example, covering 708 may be used to protect a battery and power management module from protective material formed around band 700 during an injection molding operation. As another example, housing 704 may be used to protect a printed circuit board assembly ("PCBA") from similar damage. Further, control housing 734 may be used to protect various types of user interfaces (e.g., switches, buttons, lights, light-emitting diodes, or other control features and functionality) from damage. In other examples, the elements shown may be varied in quantity, type, manufacturer, specification, function, structure, or other aspects in order to provide data capture, communication, analysis, usage, and other capabilities to band 700, which may be worn by a user around a wrist, arm, leg, ankle, neck or other protrusion or aperture, without restriction. Band 700, in some examples, illustrates an initial unlayered device that may be protected using the techniques for protective overmolding as described above.

FIG. 8 illustrates a view of an exemplary data-capable strapband having a first molding. Here, band 800 includes molding 802, analog audio plug (hereafter "plug") 804, plug housing 806, button 808, framework 810, control housing 812, and indicator light 814. In some examples, a first protective overmolding (i.e., molding 802) has been applied over band 700 (FIG. 7) and the above- described elements (e.g., covering 704, flexible circuit 706, covering 708, motor 710, coverings 714- 724, analog audio plug 726, accessory 728, control housing 734, control 736, and flexible circuit 738) leaving some elements partially exposed (e.g., plug 804, plug housing 806, button 808, framework 810, control housing 812, and indicator light 814). However, internal PCBAs, flexible connectors, circuitry, and other sensitive elements have been protectively covered with a first or inner molding that can be configured to further protect band 800 from subsequent moldings formed over band 800 using the above-described techniques. In other examples, the type, configuration, location, shape, design, layout, or other aspects of band 800 may be varied and are not limited to those shown and described. For example, plug 804 may be removed if a wireless communication facility is instead attached to framework 810, thus having a transceiver, logic, and antenna instead being protected by molding 802. As another example, button 808 may be removed and replaced by another control mechanism (e.g., an accelerometer that provides motion data to a processor that, using firmware and/or an application, can identify and resolve different types of motion that band 800 is undergoing), thus enabling molding 802 to be extended more fully, if not completely, over band 800. In yet other examples, molding 802 may be shaped or formed differently and is not intended to be limited to the specific examples shown and described for purposes of illustration.

FIG. 9A illustrates a view of an exemplary data-capable strapband having a second molding. Here, band 900 includes molding 902, plug 904, and button 906. As shown another overmolding or protective material has been formed by injection molding, for example, molding 902 over band 900. As another molding or covering layer, molding 902 may also be configured to receive surface designs, raised textures, or patterns, which may be used to add to the commercial appeal of band 900. In some examples, band 900 may be illustrative of a finished data capable strapband (i.e., band 700 (FIG. 7), 800 (FIG. 8) or 900) that may be configured to provide a wide range of electrical, electronic, mechanical, structural, photonic, or other capabilities. Here, band 900 may be configured to perform data communication with one or more other data-capable devices (e.g., other bands, computers, networked computers, clients, servers, peers, and the like) using wired or wireless features. For example, a TRRS-type analog audio plug may be used (e.g., plug 904), in connection with firmware and software that allow for the transmission of audio tones to send or receive encoded data, which may be performed using a variety of encoded waveforms and protocols, without limitation. In other examples, plug 904 may be removed and instead replaced with a wireless communication facility that is protected by molding 902. If using a wireless communication facility and protocol, band 900 may communicate with other data-capable devices such as cell phones, smart phones, computers (e.g., desktop, laptop, notebook, tablet, and the like), computing networks and clouds, and other types of data-capable devices, without limitation. In still other examples, band 900 and the elements described above in connection with FIGs. 1-9, may be varied in type, configuration, function, structure, or other aspects, without limitation to any of the examples shown and described. In some examples, button 906 may be part of a button assembly that is waterproof.

FIG. 9B illustrates a cross-section view of an exemplary button assembly on a data-capable strapband. Here, button assembly 910 includes molding 902, button 906, button inner housing 912, button shaft 914, button inner housing O-ring 916, button outer housing O-ring 918, button shaft spacer 920, button outer housing 922, flexible circuit support base 924, flexible circuit 926, dome switch 928, clip feature 930, and protruding portion 932. Like-numbered and named elements in this view may describe the same or substantially similar elements as above (e.g., in FIG. 9A). In some examples, button 906 may be depressed, or otherwise manipulated, to send signals to flexible circuit 926 (e.g., through button shaft 914, button shaft spacer 920, dome switch 928 and/or other intermediary structures). In other examples, button 906 may send signals to circuits other than flexible circuit 926. In some examples, button 906 may be shaped to fit over button shaft 914 such that button 906 and button shaft 914 move together when button 906 is depressed. Button shaft 914, in turn, may be shaped to fit over button shaft spacer 920 such that button shaft 914 and button shaft spacer 920 move together.

In some examples, dome switch 928 may be formed of metal (e.g., stainless steel, metal alloy, or other metal) or other conductive material, in the shape of a flattened dome, and may be sealed or substantially sealed. As used herein, the term "seal" refers to the act of, or a structure for, sealing or substantially sealing (i.e., protecting) an environment from another environment. In some examples, dome switch 928 also may be waterproof or water-resistant, and may form a waterproof or water- resistant seal over a portion of flexible circuit 926. Dome switch 928 also may be formed with protruding portion 932 atop dome switch 928's flattened dome, protruding portion 932 configured to make contact with button shaft spacer 920. In some examples, dome switch 928 may be operable to connect a voltage from a voltage source (not shown) to flexible circuit 926. For example, when button 906 is depressed, button shaft 914 may be moved, which in turn may move button shaft spacer 920, which in turn may make contact with dome switch 928 and cause dome switch 928 to connect a voltage to an I/O port on flexible circuit 926, or other processor circuit.

In some examples, flexible circuit 926 may recognize a voltage change event as a button press to trigger actions (e.g., activate a sensor or a group of sensors, change a mode of operation, display information, or other actions) by a data-capable band, as described herein. In some examples, flexible circuit 926 may be supported by flexible circuit support base 924. For example, flexible circuit support base 924 may comprise a flat surface against which at least a portion of flexible circuit 926 may rest, or otherwise be held against, which may keep that portion of flexible circuit flat to maintain constant contact with, and thus a waterproof seal against, a perimeter or circumferential portion of dome switch 928. In other examples, flexible circuit support base 924 may be formed and positioned differently than described.

In some examples, the cavity in which dome switch 928 resides may be sealed or substantially sealed from exposure to water or other environmental elements (e.g., dust particles, other liquids, harmful gases, and other elements) outside of the cavity using button inner housing O-ring 916. In some examples, button inner housing O-ring 916 may comprise a ring of material that forms a seal between button inner housing 912 and button shaft 914. Button inner housing O-ring 916 may be formed using a variety of materials, including rubber, plastic, thermoplastic, thermoplastic elastomer, or other materials. Button inner housing O-ring 916 may be configured to form the seal using a mechanical interference fit (i.e., compression), and may form a ring around a circumference of button shaft 914, fitting closely (i.e., inhibiting or preventing air, other gases and liquids from crossing) between button shaft 914 and button inner housing 912. In some examples, a seal formed by button inner housing O-ring 916 may be reinforced using a waterproof or water-resistant lubricant. In other examples, button inner housing O-ring 916 may be treated otherwise (e.g., with chemicals, supplemental structures, or other treatments) to reinforce its waterproof or water-resistant property.

In some examples, button inner housing 912 and the elements housed within button inner housing 912, including a portion of button 906, button shaft 914, button inner housing O-ring, and button shaft spacer 920 (collectively "button inner housing assembly"), may be sealed or substantially sealed against button outer housing 922 using button outer housing O-ring 918. In some examples, button outer housing O-ring 918 may comprise a ring of material that forms a seal between button inner housing 912 and button outer housing 922 using a mechanical interference fit (i.e., compression), and may form a ring around a circumference of button inner housing 912, fitting closely (i.e., inhibiting or preventing air, other gases and liquids from crossing) between button inner housing 912 and button outer housing 922. Button outer housing O-ring 918 may be formed using a variety of materials, including rubber, plastic, thermoplastic, thermoplastic elastomer, or other materials. In some examples, a seal formed by button outer housing O-ring 918 may be reinforced using a waterproof or water-resistant lubricant. In other examples, button outer housing O-ring 918 may be treated otherwise (e.g., with chemicals, supplemental structures, or other treatments) to reinforce its waterproof or water-resistant property.

In some examples, button inner housing 912 and button outer housing 922 may be held together using clip feature 930. In some examples, clip feature 930 comprises an engaging structure on button inner housing 912 and a complementary engaging structure on button outer housing 922 configured to hold button inner housing 912 and button outer housing 922 together, for example, without the need for adhesives. An engaging structure may be any structure formed to engage (i.e., clip, latch, couple, hold, or otherwise engage) with another structure. In some examples, clip feature 930 may provide a waterproof seal between button inner housing 912 and button outer housing 922. In other examples, clip feature 930 may not provide a waterproof seal between button inner housing 912 and button outer housing 922, in which case button outer housing O-ring 918 may be used to provide a waterproof seal between button inner housing 912 and button outer housing 922, as described above.

In some examples, button shaft spacer 920 may be included in button assembly 910 to provide additional space (i.e., air gap) between button shaft 914 and flexible circuit 926, and thereby reduce electrostatic discharge events. In some examples, button 906 and button shaft 914 each may be made of a conductive material (e.g., stainless steel, copper, silver, other metals, other alloys, or other conductive material). Button shaft spacer 920 may be provided between button shaft 914 and dome switch 928 to prevent, or reduce the likelihood of, electrostatic discharge events from being coupled to sensitive electronic components in a data-capable strapband through the path of button 906 to button shaft 914 to dome switch 928 to flexible circuit 926, which may include metal circuit traces that couple to the sensitive electronic components. In some examples, the additional space between button shaft 914 and flexible circuit 926 increases resistance to electrostatic discharge events (e.g., it may take a higher electrostatic voltage or voltages to break down (i.e., jump or cross) the additional air gap in the space). In some examples, protruding portion 932 of dome switch 928, described above, may further create additional space between button shaft 914 and flexible circuit 926. In other examples, the number, type, function, configuration, ornamental appearance, or other aspects shown may be varied without limitation.

FIG. 9C illustrates a cross-section view of another exemplary button assembly on a data- capable strapband. Here, button assembly 950 includes molding 902, button 906, button inner housing 952, button shaft seal 960, button outer seal 958, button shaft 956, button outer housing 962, flexible circuit support base 964, flexible circuit 966, and dome switch 968. Like-numbered and named elements in this view may describe the same or substantially similar elements as above (e.g., in FIGs. 9A-9B). In some examples, button shaft seal 960 may form a waterproof, water-resistant, or other type of seal, to protect dome switch 968, flexible circuit 966, and/or other components from water, other liquids, particles, harmful gases, or other contaminants. In some examples, button shaft seal 960 may be formed using a variety of materials, including rubber, plastic, thermoplastic, thermoplastic elastomer, or other materials. In some examples, button shaft seal 960 may form a seal using a mechanical interference fit, as described herein (e.g., be compressed between button inner housing 952 and button outer housing 962, be formed to fit close or tight with button shaft 956, be formed with a wall, plug, protrusion or the like that fits into a depression or groove formed on button shaft 956, button inner housing 952 and/or button outer housing 962, or the like). In some examples, button shaft seal 960 may be reinforced using a waterproof or water-resistant lubricant. In other examples, button shaft seal 960 may be treated otherwise (e.g., with chemicals, supplemental structures, or other treatments) to reinforce its waterproof or water-resistant property. In some examples, button shaft 956 may be shaped to fit onto button shaft seal 960 such that button shaft 956 and button shaft seal 960 move together, for example, when button 906 is depressed (i.e., pushed in). In some examples, button shaft seal 960 may be formed as shown, with one or more walls (e.g., protrusions, plugging feature, or the like) that fit or plug into a groove (e.g., indentation, channel, depression, recess, or the like) shaped to receive and be complementary in shape to the one or more walls. In some examples, button shaft seal 960 also may be formed with one or more outer walls, as shown, disposed between button inner housing 952 and button outer housing 962. In other examples, button shaft seal 960 may be formed differently, and is not intended to be limited to the specific examples shown and described for purposes of illustration.

In some examples, button outer seal 958 may be formed as a ring, and disposed between button inner housing 952 and button 906. In some examples, button outer seal 958 may form a seal, as described herein, protecting button shaft 956 and/or other internal components associated with the button from water or other environmental elements (e.g., dust particles, other liquids, harmful gases, and other elements) outside of button assembly 950.

In some examples, button 906 may be depressed to initiate an action involving flexible circuit 966. For example, when button 906 is depressed, button shaft 956 may in turn be pushed or moved in a same or similar direction, which may in turn move button shaft seal 960 in a same or similar direction, which in turn may make contact with dome switch 968, causing dome switch 968 to connect a voltage to an I/O port on flexible circuit 966, or other processor circuit. In other examples, the number, type, function, configuration, ornamental appearance, or other aspects shown may be varied without limitation. FIG. 10 illustrates an exemplary process for component protective overmolding using protective external coatings. Here, process 1000 includes selectively applying a material (such as those described above) substantially over a framework that is coupled to one or more elements (1002). Selective application of the material, in some examples, may refer to point applications of a material (e.g., an epoxy or other material used to protect an underlying element from being damaged during subsequent deposition, formation, or molding phases of other material). As used herein, a framework may be an internal substrate, wafer, stiffener, or the like, providing both an internal structure for bands 700-900 (FIGs. 7-9) and a structure to which the one or more elements may be mounted or coupled, either directly or indirectly. In some examples, the one or more elements may include any type of electrical, electronic, mechanical, chemical, or other type of device, component, sub-component, mechanism that is configured to receive, transmit, process, or perform a data operation (i.e.,

"operation") using data gathered from a sensor coupled to bands 700-900. Also, as used herein, "sensory input" may refer to any type, classification, powered or unpowered, of sensor configured to sense data and information regarding the internal or external environment of bands 700-900.

After selectively applying the material substantially over the framework coupled to one or more elements, a protective layer is molded over the framework, element(s), and selectively-applied material (1004). After molding the protective layer, a coating may be formed over the protective layer (1006). In some examples, the coating is formed to provide a protective property, as described above.

As used herein, "coating" is to be distinguished from protective coating 208 (FIG. 2) in that the former is used to provide a protective property to the structure to which it is applied. In some examples, the protective property may include protecting bands 700-900 (FIGs. 7-9) from external damage due to shock, wear, immersion (in various types of liquids, including water), temperature, pressure, or other environmental conditions (or lack thereof, including vacuum). In other examples, a protective property may be a characteristic of a coating that, when applied, protects a wearer or users. For example, material used for a coating may include anti-bacterial or medical-grade (i.e., any type of material or combination of materials, synthetic or organic, that have been tested and deemed suitable for biological uses, including those internal and external to organisms or bodies) materials such as TPE, polymers, elastomers, and others. Other protective properties of a coating may include being water-proof, water-resistant, oleophobic, hydrophobic, hardened (i.e., protected from damage due to shock, which may require shock or impact-absorbent materials that distribute kinetic energy when applied via force or pressure), ultraviolet radiation (hereafter "UV")-protective or resistive (i.e., resists color fading), and others, without limitation. Protective properties may refer to any property that protects the framework, elements, material, moldings, coatings, or the like from either external or internal damage or conditions that could result in damage. In other examples, process 1000 may be implemented differently in the order, function, configuration, or other aspects provided and is not limited to the examples shown and described above.

FIG. 11 illustrates an alternative exemplary process for component protective overmolding using protective external coatings. As an alternative process to those described above, material may be provided (e.g., formed, molded, deposited, sprayed, dipped, applied with a brush (i.e., brushed), or the like) over a structure of a device (1 102). In some examples, a device (e.g., bands 700-900 (FIGs. 7-9)) may be configured to perform one or more operations, as described above, using data received from various types and quantities of sensory inputs. As used herein, the material may be applied to secure an element (e.g., a sensor, battery, motor, detector, circuit, or any other type of element, as described above) to a framework or stiffener of a device. Applying material may also refer to the molding of a layer of material over a framework and elements, providing a hermetic or substantially hermetic or waterproof enclosure. In other examples, applying material may refer to the formation of a single or multiple layers of material over a device. After applying the material, a coating is formed over it to provide a protective property, such as those described above (1 104). In other examples, process 1 100 may be implemented differently in the order, function, configuration, or other aspects described and is not limited to the examples provided above.

FIG. 12 illustrates another alternative exemplary process for component protective overmolding using protective external coatings. As a further alternative process to those described above, material is selectively applied over a framework coupled to one or more elements (1202). After applying the material over the framework and coupled element(s), one or more layers (e.g., coatings, such as those described above) are molded to provide a protective property (1204). In other examples, process 1200 may be implemented differently in the order, function, configuration, or other aspects described and is not limited to the examples provided above.

FIG. 13 A illustrates a side view of an exemplary data-capable strapband having components for relieving strain. Here, band 1300 includes tubes or tubing ("tubing") 1302-1304, spacers 1306-1312 and tape loops 1314-1320. As shown, like numbered elements shown in this drawing may refer to the same or a substantially similar element previously described (e.g., in FIG. 7). As shown, tubing 1302-1304 may cover some of the above-described elements (e.g., framework 702, covering 704, coverings 714-724, and flexible circuits 737-738) of band 700 (FIG. 7), allowing them to move or slide within the tubing. In other examples, tubing 1302-1304 may cover more or fewer elements of band 700 (not shown). In some examples, tubing 1302-1304 may protect one or more elements of band 1300 during an overmolding process, as described herein, or other steps in the manufacturing process. In some examples, a protective material (e.g., UV curable material) may be applied to tubing 1302-1304 to enhance the protective properties of tubing 1302-1304. In some examples, tubing 1302-1304 may be a hollow length of material with an opening on each end within which at least part of a band (e.g., band 700 or band 1300) may be covered or protected. For example, tubing 1302-1304 may comprise Teflon® or other materials that exhibit similar characteristics (e.g., durability, flexibility, ability to protect elements of the band covered within, or other characteristics). In some examples, tubing 1302-1304 may cover the length of a flexible circuit (e.g., flexible circuits 737-738), a flexible connector (e.g., a cable or wire assembly connecting a flexible circuit to a plug (not shown)), and/or other elements on band 1300, allowing the flexible circuit and flexible connector to move (e.g., slide) inside tubing 1302-1304. In some examples, tape loops 1314-1320 may be used to secure or hold tubing 1302-1304 in place during one or more steps in a manufacturing process (e.g., assembly, overmolding, or other steps). In other examples, tape loops 1314-1320 may be placed elsewhere to relieve strain on cables or wires that are part of a flexible circuit or a flexible connector. In still other examples, one or more elastic bands or other materials configured to loop around a segment of band 1300 to secure elements on band 1300 may be used instead of tape loops 1314-1320.

In some examples, spacers 1306-1312 may be placed on or between elements of band 1300 within tubing 1302-1304 to maintain spacing on band 1300 for a flexible circuit, flexible connector (e.g., a wire or cable assembly connecting a flexible circuit to a plug (not shown)), and/or other elements of band 1300 as they may move during overmolding or when band 1300 is flexed, bent or curved ("flexed"), for example, into an oval, or other curved, shape after overmolding or during use. In some examples, spacers 1306-1312 may prevent the flexible circuit, flexible connector (e.g., a wire or cable assembly connecting a flexible circuit to a plug (not shown)), and/or other elements of band 1300 from bunching up when band 1300 is flexed.

As shown in FIG. 13B spacers may take various forms. FIG. 13B illustrates exemplary spacers, including single spacer 1322, double spacer 1324, and triple spacer 1326 (collectively, spacers 1322-1326). In some examples, the spacers 1322-1326 may be shaped like a speed bump. In other examples, spacers 1322-1326 may be shaped differently, for example, with a flat or square top, a more pointed top, a more circular or parabolic shaped bump, or other appropriate shape. In some examples, spacers 1322-1326 may vary in size (e.g., a bigger bump or a smaller hump). In some examples, spacers 1322-1326 may be comprised of a compliant material. In some examples, spacers 1322-1326 may be formed with a single bump (e.g., single spacer 1322), a double bump (e.g., double spacer 1324), or a triple bump (e.g., triple spacer 1326). In some examples, spacers 1322-1326 may be placed together in a row along band 1300. In other examples, spacers 1322-1326 may be placed separately on band 1300, with one or more other elements placed in between. In still other examples, band 1300 may be implemented differently, with more or fewer elements.

In some examples, UV curable material (not shown), as described herein, may be applied to a wire or cable assembly (not shown), a flexible circuit (e.g., flexible circuits 737-738), or another element of band 1300, prior to placing one or more of tubing 1302-1304, spacers 1306-1312, and tape loops 1314-1320 on band 1300. In some examples, one or more of tubing 1302-1304, spacers 1306- 1312, tape loops 1314-1320, and the application of UV curable material may be used to relieve strain on a flexible circuit (e.g., flexible circuits 737-738), a wire or cable assembly (not shown), or another element of band 1300. For example, a combination of tubing 1302-1304, spacers 1306-1312, tape loops 1314-1320, and the application of UV curable material may be used to prevent a solder joint from breaking during overmolding or flexing (e.g., as may occur when band 1300 is in use). In another example, tubing 1302-1304 and tape loops 1314-1320 may hold spacers 1306-1312 in place to prevent elements of band 1300 (e.g., a wire or cable assembly on a flexible circuit or flexible connector) from bunching up. In yet another example, spacers 1306-1312 may be held in place using other means. In some examples, tape loops 1314-1320 may secure tubing 1302-1304 to framework 702 or another element of band 1300, or to prevent parts of tubing 1302-1304 from sliding or moving along framework 702. In other examples, tape loops 1314-1320 and tubing 1302-1304 may be used without spacers 1306-1312 to relieve strain on an element. For example, one or more of tape loops 1314-1320 may hold an element of band 1300 in place (e.g., on framework 702, with tubing 1302 or tubing 1304, or to another structure or element of band 1300), including preventing the element (e.g., a wire or cable assembly on a flexible circuit or flexible connector) from bunching up during flexing (e.g., thereby straining other parts of the wire, cable, circuit, connector, or other part of the band). In other examples, band 1300 may be implemented with more or fewer elements or components for relieving strain.

FIGS. 14A-B illustrate an exemplary data-capable strapband having a tethered cap. Here, band 1400 includes cap 1402, plug 1404, button 1406, opening 1408, tether 1410, plate 1412, post 1414, cap mating end 1416, and base mating end 1418. Like-numbered and named elements in this view may describe the same or substantially similar elements as above. In some examples, plug 1404 may be an analog audio plug (e.g., a TRRS-type, a TRS-type, a TS-type, or other type of audio connector or plug). In some examples, plug 1404 may be configured to transmit and receive data. For example, plug 1404 may be configured to transmit data gathered or collected by one or more sensors within band 1400, as described herein. In another example, plug 1404 may be configured to receive data, for example software upgrades or patches, from various sources, including mobile phones, other mobile communication devices, computers, laptops, mobile computing devices, tablet devices, or other sources. In some examples, plug 1404 may communicate (i.e., transmit or receive data) with a source or other electronic device using an adapter suitable for adapting analog signals transmitted by plug 1404 into a signal type or format readable by the source or other electronic device. For example, plug 1404 may use a USB-type adapter to communicate with a computer.

In some examples, cap 1402 may be placed over plug 1404 to hide plug 1404 from view. For example, cap 1402 may have an exterior surface that matches or substantially matches (e.g., same or similar look and feel, texture, color, outer perimeter shape, or the like) an exterior surface on the rest of band 1400 or a base portion thereof (i.e., a portion of the band starting at base mating end 1418 and ending at button 1406). In some examples, an exterior surface of cap 1402 may match an exterior surface of the base portion of band 1400 by being molded with the same or similar material as an outer molding formed over a base portion (i.e., a framework (not shown), as described herein) of band 1400. In other examples, an exterior surface of cap 1402 may be formed using a different material that substantially matches an exterior surface of a base portion of band 1400. In still other examples, an exterior surface of cap 1402 may not match an exterior surface of a base portion of band 1400. In some examples, an exterior surface of cap 1402 may be used for the placement of markings, indicia, or other identifying or decorative features, elements or the like (e.g., have a brand name, device name, trademark, logo, or otherwise marked). In some examples, cap 1402 also may be configured or formed to protect plug 1404 from contamination or damage (e.g., from water, dirt, dust, chemicals, gases, or other materials that may contaminate or damage plug 1404), for example by coupling with a base portion (i.e., at base mating end 1418) of band 1400, as described herein. In other examples, the number, type, function, configuration, ornamental appearance, materials, or other aspects shown or described may be varied without limitation.

In some examples, cap 1402 may include cap mating end 1416, for example on the same end as the opening 1408, configured to meet with base mating end 1418. In some examples, cap mating end 1416 may substantially match, or have the same outer perimeter size, shape, and/or material as, base mating end 1418 at the base of plug 1404. In some examples, cap mating end 1416 may touch or make contact with base mating end 1418 when cap 1402 is placed over plug 1404 to cover (e.g., enclose or substantially enclose) plug 1404. In other examples, cap mating end 1416 may couple with (e.g., lock with, clip onto/into, screw onto/into, recede into, create a hermetic seal with, magnetically adhere to, or otherwise couple with) base mating end 1418. In other examples, the number, type, function, configuration, ornamental appearance, materials, or other aspects shown or described may be varied without limitation.

In some examples, opening 1408 may lead or open into a cavity, or hollow space, configured to house plug 1404 (e.g., shaped and sized to fit the contours of plug 1404, or otherwise shaped (e.g., tubular, cylindrical, rectangular box, or other shape) and sized to fit plug 1404). In some examples, opening 1408 may be configured (e.g., sized, shaped, or otherwise configured) to receive some or all of plug 1404, as shown. For example, plug 1404 may be 3.5mm in diameter and opening 1408 may have a diameter configured to receive, house, or otherwise accommodate, plug 1404. In some examples, opening 1408 may have different sizes that are configured to receive, house, or otherwise accommodate, plug 1404, or other plugs of various shapes, sizes, lengths, or diameters, without limitation. In some examples, cap 1402 may be coupled to a base portion of band 1400 using tether 1410. In some examples, cap 1402 may be placed over plug 1404 to cover plug 1404, and also may be removed to uncover plug 1404. In some examples, tether 1410 may remain coupled to both cap 1402 and a structure within a base portion of band 1400 (i.e., a framework (not shown) within band 1400) when cap 1402 is removed to uncover plug 1404. Thus, even when plug 1404 is uncovered, cap 1402 may remain coupled to a base portion of band 1400 using tether 1410. In some examples, tether 1410 may comprise an elastic leash (e.g., formed using rubber, nylon, polymer, or other elastic natural or synthetic material). In some examples, tether 1410 may have a hole sized to fit over post 1414, wherein tether 1410 is hooked or looped over post 1414. In some examples, tether 1410 may be coupled to cap 1402 by hooking or looping over post 1414 and being sandwiched between a bed (not shown) and plate 1412.

In some examples, cap 1402 may include cap mating end 1416, for example on the same end as the opening 1408, configured to meet with base mating end 1418. In some examples, cap mating end 1416 may substantially match, or have the same outer perimeter size, shape, and/or material as, base mating end 1418 at the base of plug 1404. In some examples, cap mating end 1416 may touch or make contact with base mating end 1418 when cap 1402 is placed over plug 1404 to cover plug 1404, for example, when cap 1402 is placed over plug 1404 and tether 1410 pulls cap mating end 1416 close with base mating end 1418. In other examples, cap mating end 1416 may couple with (e.g., lock with, clip onto/into, screw onto/into, recede into, create a hermetic seal with, magnetically adhere to, or otherwise couple with) base mating end 1418. In still other examples, the number, type, function, configuration, ornamental appearance, materials or other aspects shown or described may be varied without limitation.

FIGS. 15A-B illustrate an alternative exemplary data-capable strapband having a tethered cap. Here, band 1500 includes cap 1502, plug 1504, button 1506, opening 1508, tether 1510, plate 1512, post 1514, cap mating end 1516, base mating end 1518, and bed 1520. Like-numbered and named elements in this view may describe the same or substantially similar elements as above. In some examples, tether 1510 may comprise a substantially inelastic or inelastic sheet of material (e.g., mylar, plastic, polymer, metal, or other synthetic or natural material). In some examples, tether 1510 may have an opening or slot that may fit over post 1514 with room for post 1514 to slide linearly from one end of tether 1510 to another end of tether 1510, as tether 1510 slides linearly along the length of bed 1520. In some examples, tether 1510 may be movably coupled to cap 1502 by hooking or looping over post 1514 and being sandwiched between bed 1520 and plate 1512. In other examples, the number, type, function, configuration, ornamental appearance, materials, or other aspects shown or described may be varied without limitation. FIGS. 16A-B illustrate another alternative exemplary data-capable strapband having a tethered cap. Here, band 1600 and cross-section view 1650 includes cap 1602, plug 1604, button 1606, tether 1610, cap mating end 1616, base mating end 1618 and cavity 1650. Like-numbered and named elements in this view may describe the same or substantially similar elements as above. In some examples, tether 1610 may comprise a sheet of pliable or flexible material (e.g., mylar, metal, rubber, leather, or other synthetic or natural material). In some examples, an end of tether 1610 may be fixed (e.g., glued, taped, stapled, fastened, secured, or otherwise permanently or semi-permanently coupled) to an inner wall of cap 1602 (e.g., a roof, side or floor of cavity 1622). In some examples, tether 1610 may be configured to curl or curve around a tip of plug 1604, as shown. In some examples, tether 1610 may have an unfixed, or otherwise moveable, portion that may be pulled out of cap 1602 when cap 1602 is moved away from the base of plug 1604 to uncover plug 1604, or may be pushed, or retracted, into cap 1602 when cap 1602 when plug 1604 is being covered. For example, a tip of plug 1604 may push tether 1610 into cavity 1622 when cap 1602 is being placed over plug 1604. In other examples, the number, type, function, configuration, ornamental appearance, materials, or other aspects shown or described may be varied without limitation.

FIGS. 17A-B illustrate an exemplary data-capable strapband coupled to a cap. Here, band 1700 includes cap 1702, button 1706, cap mating end 1716 and base mating end 1718. Like- numbered and named elements in this view may describe the same or substantially similar elements as above. In some examples, cap mating end 1716 may couple with (e.g., lock with, clip onto/into, screw onto/into, recede into, create a hermetic seal with, magnetically adhere to, or otherwise couple with) base mating end 1718, thereby coupling cap 1702 to a base portion of band 1700 extending from base mating end 1718 to button 1706. In some examples, cap mating end 1716 may be coupled to base mating end 1718 by placing cap 1702 onto a base portion of band 1700 until cap mating end 1716 meets base mating end 1718, and rotating cap 1702 about an axis extending from cap mating end 1716 to an opposite end of cap 1702. For example, cap mating end 1716 and base mating end 1718 may comprise complementary threads (e.g., cap mating end 1716 having an external (i.e., male) thread and base mating end 1718 having an internal (i.e., female) thread, or vice versa) for screwing cap mating end 1716 onto or into base mating end 1718. In some examples, the threads may be configured to engage when cap 1702 is turned at a predetermined angle, and to stop cap 1702's rotation when cap 1702 is in a desired end position (i.e., an upright position). In other examples, cap mating end 1716 and base mating end 1718 may couple using other locking or securing mechanisms (e.g., clip, magnet, friction or other coupling mechanism). In some examples, cap mating end 1716 and base mating end 1718 may couple to form a seal sufficient to keep out water or other contaminants that may damage a plug (not shown) housed within cap 1702. In some examples, a magnet (or ferrous or other magnetic material) may be placed on or under an external surface of a part or portion of band 1700 and cap 1702 to create a magnetic surface on cap 1702 and another magnetic surface on another part of band 1700. In some examples, cap 1702's magnetic surface may include a part or a whole surface. In some examples, a part or a whole surface of band 1700 may be magnetic. For example, cap 1702's magnetic surface may be configured to adhere to a magnetic surface on another part of band 1700, wherein cap 1702 may be held temporarily against a side of band 1700 when cap 1702 is removed to uncover a plug (not shown). In other examples, band 1700 may be equipped with a clip or other retention structure configured to hold cap 1702 temporarily when cap 1702 is removed to uncover a plug (not shown). In other examples, the number, type, function, configuration, ornamental appearance, materials, or other aspects shown or described may be varied without limitation.

FIGS. 18A-B illustrate an exemplary data-capable strapband and cap assembly. Here, cap assembly 1800 includes cap 1802, wall 1812, housing 1814, opening 1816, retaining clip 1810, indentation 1820 and prongs 1822-1824. Also shown are plug 1804, plug base 1806 and band 1808. Like-numbered and named elements in this view may describe the same or substantially similar elements as above. In some examples, retaining clip 1810, comprising indentation 1820 and prongs 1822 and 1824, may be placed into cap 1802 and configured to retain (i.e., keep), for example, an end of plug 1804 in place. For example, indentation 1820 may be configured to secure retaining clip 1810 within cap 1802 such that a portion of retaining clip 1810 fits between wall 1812 (i.e., indentation 1820 may make contact with a side of wall 1812) and another internal surface of cap 1802. In other examples, retaining clip 1810 may be placed or secured into cap 1802 differently than shown.

In some examples, retaining clip 1810 may be formed using a variety of materials, including metal, rubber, plastic, thermoplastic, thermoplastic elastomer, other types of materials having a material memory (i.e., able to be flexed, bent, deformed, or otherwise displaced, when pressure is applied, and to reassume or recover an original shape when pressure is removed), or the like. In some examples, prongs 1822-1824 may be configured to hold an end of plug 1804, and to allow an end of plug 1804 to pass between prongs 1822-1824 (e.g., prongs 1822-1824 may be shaped, positioned, or otherwise configured to allow an end of plug 1804 to pass in between and be held by prongs 1822-1824). In this example, prongs 1822-1824 may be configured to flex, bend, deform, or otherwise be displaced (i.e., by being formed of a material having a material memory), when an end of plug 1804 passes such that retaining clip 1810 clips onto and retains plug 1804 in place. In other examples, the number, type, function, configuration, ornamental appearance, materials, or other aspects shown or described may be varied without limitation.

In some examples, cap 1802 may include housing 1814 and opening 1816. In some examples, opening 1816 may be disposed on one end of housing 1814, and there may be another opening (not shown) disposed at another end of housing 1814, for example, opposite to opening 1816. In some examples, housing 1814 may have a cavity or internal passageway running between opening 1816 and another (i.e., opposite) opening, and thus housing 1814 may be configured to house a portion of plug 1804 and plug base 1806. In some examples, cap 1802 may include a top cover (not shown) covering internal components and spaces (e.g., housing 1814, retaining clip 1810, wall 1812, and the like). In other examples, the number, type, function, configuration, ornamental appearance, materials, or other aspects shown or described may be varied without limitation.

Although the foregoing examples have been described in some detail for purposes of clarity of understanding, the above-described inventive techniques are not limited to the details provided. There are many alternative ways of implementing the above-described invention techniques. The disclosed examples are illustrative and not restrictive.
