  • DETAILED DESCRIPTION OF THE INVENTION
  • The invention pertains to a cover for a portable electronic device. The cover can include at least one electrical component. For example, in one embodiment, an electrical component can be embedded in the cover. When the cover is placed on or mated with the portable electronic device, the electrical component embedded in the cover is able to interact with electrical circuitry of the portable electronic device. Advantageously, the cover can not only provide a protective and/or ornamental covering for the portable electronic device but can also augment the electrical capabilities of the portable electronic device.

Examples of portable, battery-powered electronic devices can include laptops, tablet computers, media players, phones, GPS units, remote controls, personal digital assistant (PDAs), and the like.
  • A cover for a portable electronic device can be made from a variety of materials. In one particular embodiment, the cover can be formed from a flexible and/or compliant material that is fitted, i.e., conforms to, the contour of the portable electronic device. For example, in one implementation, the cover is a flexible film (e.g., a label) that attaches to a surface of the portable electronic device. In another example, the cover can be a compliant enclosure formed from materials, such as rubber or silicone, that wrap and stretch around the surfaces of the portable electronic device. The cover can also be referred to as a skin.
  • Embodiments of the invention are discussed below with reference to FIGS. 2A-18. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes as the invention extends beyond these limited embodiments.
  • FIG. 2 is a simplified diagram of an electronic cover 200 for a portable electronic device, in accordance with an embodiment of the present invention. The electronic cover 200 may be an outer covering with integrated electronics that can be physically and operatively coupled to a portable electronic device.
  • The electronic cover 200 may be configured to cover a portion of one or more external surfaces of the portable electronic device for ornamental and/or protective purposes. Additionally, the electronic cover 200 can be configured at act as an electronic accessory to the portable electronic device 200, i.e., a supplementary system that improves the functional capabilities of the portable electronic device. In most cases, the electronic cover 200 is a distinct element, which is not part of the originally designed portable electronic device. Instead, the electronic cover 200 is an add-on or an accoutrement of the portable electronic device. The electronic cover 200 may be configured to help protect the portable electronic device (i.e., it may serve as armor or shock protection that helps prevent structural and/or surface damage to the portable electronic device). Additionally or alternatively, the electronic cover 200 may provide ornamentation to the portable electronic device (i.e., it may help define the overall ornamental appearance of the electronic device). The electronic cover 200 can also permit personalized ornamentation. The electronic cover 200 may also provide tactility in order to improve the feel and grip to the portable electronic device.
  • The electronic cover 200 can at least partially conforms to the outer shape of the portable electronic device. For example, by providing an internal shape/inner surface and/or being flexible enough to follow the contour of the portable electronic device. The external shape of the outer covering may be widely varied. It may be designed for ornamental, protection, and/or ergonomic reasons. Generally however, it tends to follow the general shape of the portable electronic device.
  • The electronic cover 200 may for example be laid, set, wrapped, spread upon, about or over a portion of the portable electronic device. The electronic cover 200 may be configured to cover a surface of the portable electronic device including a portion of a single side, multiple sides, and/or all sides of the portable electronic device. For example, the electronic cover 200 may be a film that is applied to a single surface of the portable electronic device (e.g., a portion or all of the front surface). The electronic cover 200 may also be a flexible covering that includes a cavity for receiving the portable electronic device and that wraps/stretches around some portion of the portable electronic device. The outer covering may be referred to (among others) as a case, shield, container, jacket, vest, skin, protector, and the like of the portable electronic device.
  • The electronic cover 200 generally includes a body or member 202 that couples to the portable electronic device. The body or member 202 may also decouple from the portable electronic device such that it is a considered a removable or detachable. The body or member 202 can be carried by the portable electronic device, but is not part of the portable electronic device. The configuration of the body or member 202 may be widely varied, but is typically configured to cover the outer surface(s) of the portable electronic device. The body or member 202 may be universal in its application (not specific to a particular device) or it may be dedicated to a particular device. In either case, the body or member 202 can be configured to follow the outer contour or shape of the surfaces of the portable electronic device. In one embodiment, the body or member 202 forms a surface layer that attaches to the outer surface of the portable electronic device. In another embodiment, the body or member forms an enclosure that includes surfaces (e.g., walls) that surround the outer surfaces of the portable electronic device. For example, the surfaces may define a cavity for placement of the portable electronic device. The body or member 202 may include access openings and tactile features that are associated with mechanisms of the portable electronic device. The tactile features may also be associated with mechanisms of the covering. Even though the general shape of the body or member 202 may be similar to the portable electronic device, the external surface of the body or member 202 may include one or more or any combination of patterns, recesses, protrusions, ridges, depressions, dimples, flaps, extensions, textures, knurls, and/or the like.
  • The electronic cover 200 can be formed from a variety of materials including, for example, but not limited to soft, hard, rigid, flexible, compliant, etc. Some examples of material types include but are not limited to paper, plastic, metal, rubber, silicon, fabric, foams, leather, ceramics, films, and the like. The material generally depends on the desired needs of the outer covering. It should be appreciated that the outer covering is not limited to a single material and may include a combination of materials. The exact combination may depend on the needs of the outer covering. Examples of trade-offs include rigid/flexible, soft/hard, soft1/soft2, plastic/metal, silicon/plastic, etc. In one particular embodiment, the outer covering is formed from flexible and/or compliant materials such as rubber, silicone, fabrics (e.g., neoprene), and various films.
  • The electronic cover 200 can be adhered to or around the portable electronic device using a variety of techniques including but not limited to: adhesive, friction, static, elasticity, suction, fasteners, snaps, connectors, and the like. In some examples, the electronic cover 200 forms an enclosure that includes a void, cavity, opening, pocket or compartment for receiving a portable electronic device therein (i.e., the portable electronic device can be placed into the void). In another example, the electronic cover 200 can be press fit onto the portable electronic device. In yet other examples, the electronic cover 200 is a surface (e.g., platform, film) that is attached to a surface of the portable electronic device (e.g., adhesive backed surface or surface with static electricity properties or a surface with suction cups). In yet other examples, the electronic cover 200 is stretched around the portable electronic device (e.g., the outer covering is flexible and conforms to the outer shape of the portable electronic device). In other examples, the electronic cover 200 can trap or surround the portable electronic device between multiple sections (i.e., lower and upper half).
  • In accordance with one embodiment, the electronic cover 200 may be formed from a soft, flexible and/or compliant material that can be wrapped around the various surfaces of the portable electronic device. For example, the material may allow the covering to stretch over the portable electronic device (e.g., form fitting). By way of example, the electronic cover 200 may be formed from a stretchable material that includes a small opening that can be stretched to accommodate the larger portable electronic device as it is inserted into the electronic cover 200 outer covering. Once the portable electronic device is inserted, the material confirms to the shape of the portable electronic device, which provides a tight fit around the surfaces of the portable electronic device. The electronic cover 200 may, for example, surround multiple side surfaces if not all of the side surfaces of the portable electronic device. In one particular example, the material may be silicon. These types of coverings are sometimes referred to as “skins” as they create a new outer layer analogous to skin.
  • The electronic cover 200 may include a variety of access openings 203 depending on the configuration of the portable electronic device. The access openings 203 provide access to features of the portable electronic device. The access openings may, for example, provide openings for one or more displays, buttons, switches, navigation pads, keys, touch pads, receivers, microphones, speakers, connectors, jacks, sensors, antennas, cameras and the like. The electronic cover 200 may also include an access opening for helping place the outer covering relative to the portable electronic device as for example in situations where the outer cover surrounds a majority of the sides of the portable electronic device.
  • In accordance with one embodiment, the electronic cover 200 can be configured to include electronic circuitry 204. The electronic circuitry 204 can include one or more electronic components, such as one or more electronic subassemblies, for connection to the portable electronic device. The one or more electronic subassemblies may interface with the portable electronic device via an existing connector of the portable electronic device, via a special connector dedicated to the outer covering or via a wireless connection. The one or more electronic subassemblies can be embedded (partially or entirely) within the walls of the electronic cover 200 and/or the electronic subassemblies can be carried by the electronic cover 200 as for example on an exterior or interior surface. The electronic subassemblies may be used to provide additional functionality to the portable electronic device and/or to extend functionalities of the portable electronic device to the electronic cover 200.
  • Advantageously, the cover or outer covering according to various embodiments can provide a paradigm shift for electronic device covers, which have conventionally been provided for protection of outer physical surfaces of portable electronic devices. Now, the cover or outer covering can operate as an electrical accessory for the portable electronic device. Here, the cover or outer covering includes active elements that can interact with active element of a portable electronic device. The cover or outer covering having active elements can be considered a smart cover or active cover. In order to be smart and/or active, the smart or active outer cover generally includes one or more electrical components that are carried by the body or member 202 of the electronic cover 200. In some cases, the components can be discrete separate components that are spaced apart from one another while still maintaining communications there between (e.g., wires, traces, flexes). In other cases, at least a portion of the components can be grouped together onto a single carrier such as a printed circuit board, flex circuit, rigid flex, subassembly or electronic enclosure. These components may be embedded and/or surface mounted. Several of the components will be described in detail below.
  • In one embodiment, the electronic cover 200 can include a connection terminal 205 for operatively connecting to the portable electronic device. The connection terminal 205 may serve as a data and/or power connection. In wired connections, the connection terminals are configured to physically connect so as to operatively couple the electronic cover 200 to the portable electronic device. For example, the interface may include a mating connection made up of corresponding mating connectors. The connector may be dedicated to the interface between covering and device. The connector may also be associated with an existing connector of the device. For example, if the device includes a female port then the covering may include a male protrusion that engages the female port. In order to allow further connection to the device when the covering is on the device, the connector of the covering may include a second connector, which in one implementation can mimic the connector of the device. In one embodiment, the first and second connectors are integrated into a single connector unit. For example, the covering may include a female/male connector. In another embodiment, the first and second connectors are separated in space but electrically coupled together as for example through the use of conductive traces, flex circuits or wires.
  • The configuration of the contacts of the connector and the signals they carry may be widely varied. For example, the spacing, numbers of pins and layout of pins (rows/columns) and the like of the connector may be varied. Furthermore, the contacts may be used for data, ground, charging, protocols, accessory identifier, audio, line in, line out, video, sensors, etc. By way of example, the connection interface may be associated with one or more of the following interfaces: PS/2, serial, parallel, network (e.g., Ethernet), USB, Firewire and/or the like. The connection interface may also include one or more remote, audio (digital or analog), video (digital or analog), and/or charging interfaces. In one example, the connection interface corresponds to a thirty (30) pin connector utilized in devices manufactured by Apple Inc. of Cupertino Calif.
  • In wireless connections, the terminals do not physically connect. For example, the interface may include a receiver and transmitter (transceiver) for wireless communications there between. By way of example, the connection interface may include one or more of the following interfaces: Bluetooth, WiFi, 802.11, optical (e.g., infrared, magnetic link (induction) and/or the like.
  • The electronic cover 200 can include a controller 208 (e.g., processor or CPU) configured to execute instructions and to carry out operations associated with either the electronic cover 200 or a portable electronic device coupled thereto. For example, using instructions retrieved, for example, from memory, the controller may control the reception and manipulation of input and output data between components of the electronic cover 200 as well as components of a portable electronic device coupled thereto. The controller may act alone or work with the controller of the portable electronic device depending on the needs of the system.
  • The controller 208 can be implemented on a single chip, multiple chips or multiple electrical components. For example, various architectures can be used for the controller, including dedicated or embedded processor, single purpose processor, controller, ASIC, etc. By way of example, the controller may include microprocessors, DSP, A/D converters, D/A converters, compression, decompression, etc. In most cases, the controller together with program code (e.g., firmware, software), such as an operating system, can operate to produce and use various data. The operating system may correspond to well known operating systems such as OS/2, DOS, Unix, Linux, and Palm OS, or alternatively to special purpose operating system, such as those used for limited purpose appliance-type devices.

Furthermore, it can be made highly elastic. Silicon rubber may include a variety of filler to adjust its properties and colors. Silicon can also be formulated as special grades with special attributes. In addition, silicon can be easily formed into a variety of shapes.
  • In one embodiment, a cover can be formed of a hard plastic. For example, the cover can be formed of polycarbonate or ABS plastic.
  • In one embodiment, a cover can be formed of a translucent material.
  • Various techniques may be used to form the desired shape of a cover including for example molding or casting techniques. Various molding techniques include compression molding, transfer molding, injection molding, and the like. Some techniques that may be useful to integrate electronics into the molded part include insert molding and/or double shot injection molding. These and other embodiments will be described in greater detail below.
  • In one embodiment, electrical components (as well as other structures) may be suspended within a mold, and the material may be allowed to be placed around it such that the electrical components are at least partially and possibly fully embedded within the walls of the cover. In some cases, select portions may be left exposed during molding. In other cases, select portions may be exposed in post molding operations (e.g., stamping, cutting). In either case, the exposed portions may be included for making post mold connections (e.g., between embedded components or between the cover and the portable electronic device). In one example, insert molding techniques may be used. During insertion molding, the mold is loaded with some or all of the electronic structures of the cover. Thereafter, material is forced into the mold (e.g., hot molten material is injected). After allowing the part to cool, the mold is opened and the product is removed. Thereafter, post molding operations are performed. For example, access openings if not part of the molded design are formed using a variety of techniques such as stamping or cutting. In addition, additional structures may be attached to the cover including, for example, more components and/or wires or traces that couple components. By way of example, portions, such as contacts, of the embedded structures may be exposed and traces may be printed on the surface of the cover between components such that they are operatively connected. The circuits may then be tested. Printing of traces and testing may be performed by folding the cover inside out. Thereafter, any remaining exposed structures (other than the connection point between the cover and the portable electronic device) may be covered up through use of coatings, epoxies, labels or more cover material. It should be appreciated that other structures may be insert molded including for example attachment mechanisms and/or ornamental features.
  • Alternatively or additionally, a cover may be formed from multiple layers that are applied successively. For example, the cover may be formed from a first layer and a second layer, both of which can be formed using successive molding operations. In on example, the first layer is formed. This may include no structure, partially embedding one or more structures, or fully embedding one or more structures. Thereafter, if desired, more electronic parts can be added as, for example, by attaching to an inner surface of the first layer. Also, traces, wires, or flex circuits can be added thereby making connections between components. Testing can also be performed. Thereafter, a second layer is formed over the first layer and over exposed electronics or circuitry (except the connection mechanism between the cover and portable electronic device remain exposed). In one implementation, a double shot injection molding techniques can be used. Double shot molding is a process for producing two integral parts by utilizing successive molding methods. In one example, material is forced into a first mold to form a first layer. Thereafter, either a half of the mold or the part is transferred to another mold (thereby acting as an insert). Thereafter material is forced into the second mold to form a second layer that integrally affixes to the first layer. In some cases, the same material is used. In other cases, different materials or the same material with different properties is used.
  • In some cases, exposed parts may be covered instead of or in addition to double injection molding. The covering applied may be provided by coatings, epoxies, paints, films and the like.
  • In one embodiment, a cover may also be formed as a laminate part. For example, the cover may include an outer layer (e.g., flexible sheet or label), one or more components attached thereto, and an inner adhesion layer. The adhesion layer allows the laminate structure to be attached to an outer surface of a portable electronic device. The components may include wires or traces as mentioned above. Furthermore, in order to provide a uniform cover, a filler may be included between the outer and inner layers between the components
  • FIG. 18 is a flow diagram of a cover formation process 1800 according to one embodiment of the invention. The cover formation process 1800 is suitable for forming a protective cover having an electrical component.
  • The cover formation process 1800 provides 1802 a mold for a protective cover for an electronic device. Here, a mold can be created to form the protective cover. The protective cover will eventually be utilized to cover a significant portion of an electronic device. An electrical component to be provided in the protective cover is also obtained 1804. As discussed above, the electrical component can take many forms and can be positioned in the protective cover at various locations. Next, the electrical component can be positioned 1806 with the mold. By positioning in the electrical component within the mold, the electrical component can be placed at a particular location with respect to the protective cover to be formed. Thereafter, the protective cover can be formed 1808 using the mold. For example, a molding compound can be injected into the mold, allowed to cure and then removed from the mold. The cured molding compound forms the protective cover whereby the electrical component is secured or embedded in the molding compound that forms the protective cover. Following the formation 1808 of the protective cover, the cover formation process 1800 can end.
  • In one embodiment, the electronic device to be covered may further be a hand-held electronic device. The term hand-held generally means that the electronic device has a form factor that is lightweight (e.g., less than about 1 pound (or 0.5 kilograms) and small enough to be comfortably held in one hand. A hand-held electronic device may be directed at one-handed operation or two-handed operation. In one-handed operation, a single hand is used to both support the device as well as to perform operations with the user interface during use. In two-handed operation, one hand is used to support the device while the other hand performs operations with a user interface during use or alternatively both hands support the device as well as perform operations during use. In some cases, the hand-held electronic device is sized for placement into a pocket of the user. By being pocket-sized, the user does not have to directly carry the device and therefore the device can be taken almost anywhere the user travels.
  • The one or more electronic subassemblies that are part of the outer covering may be widely varied. The electronic subassemblies may include one or more electronic components such as integrated circuits (i.e., chips), circuit boards, flex circuits, wires, Light Emitting Diodes (LEDs), electronic circuits, switches, and other circuitry. The electronic subassemblies may, for example, extend Input/Output (I/O) of the portable electronic device into the covering (e.g., visual indicators, display, audio, tactile, haptics, buttons, switches, detectors, touch pads, navigation pads, joysticks, keys, etc). Additionally or alternatively, the electronic subassemblies may, for example, be associated with one or more sensors include for example accelerometers, GPS, proximity, biometric, force and/or the like that extend the capabilities of the portable electronic device. Additionally or alternatively, the electronic subassemblies may, for example, be associated with a connection interface (e.g., mechanical connector, inductance, wireless). Additionally or alternatively, the electronic subassemblies may, for example, be associated with memory, CPU or processing capabilities, battery, solar charging, kinetic charging, antenna (multiple selectable antennas, supplemental antennas, boosters, etc.), and others. Additionally or alternatively, the electronic subassemblies may, for example, be associated with software upgrades or new software applications. For example, the outer covering may include a memory device including a new software application with a new I/O dedicated to the new application. Additionally or alternatively, the electronic subassemblies may, for example, be associated with card slots as for example SIMM cards, flash cards, memory cards, game cards, etc.
  • The subassemblies may be operatively coupled to the portable electronic device via wired or wireless connections. If wired, at least one of the subassemblies may be associated with or coupled to a connector that plugs into or otherwise mechanically interfaces the portable electronic device. The connector may, for example, be a data and/or power connector. The connector may include various pins or contacts that support various signals. Examples include USB, Firewire that include 4-6 pins. Other examples include connectors with larger pin layouts such as for example the 30 pin connector that support iPods and iPhones manufactured by Apple Inc. of Cupertino, Calif. In one implementation, the connector includes a first connector that mates with the portable electronic device and a second connector that extends the portable electronic device's connector to the outside of the outer covering (e.g., male/female connectors). For wireless capabilities, the subassemblies may include one or more various chipsets that support wireless functionality of the portable electronic device including for example Bluetooth, 802.11, RF, IR, etc.
  • In one implementation, the outer covering is compliant and the one or more subassemblies and associated circuitry are at least partially embedded within the compliant outer covering. For example, the material may be molded around a portion of the subassembly including associated circuitry and wiring such that the subassembly and the outer covering become a single integral unit. In one example, insert molding techniques are used to mold around the various subassemblies. The subassemblies may be fully embedded, embedded with an exposed internal surface or feature, or embedded with an exposed external surface or feature, or embedded with an exposed internal and external surface or feature. Additionally or alternatively, the subassemblies may be applied to the surfaces of the outer covering rather than being fully or partially enclosed within the outer covering. For example, the subassemblies may be attached to an internal surface of the outer covering and, the subassemblies may be attached to an external surface of the outer covering. As should be appreciated, any combination of embedded and surface mount may be used to achieve the desired effect. For example, in one embodiment, the subassemblies are only embedded. In another embodiment, the subassemblies are only surface mounted. In yet another embodiment, the subassemblies are both embedded and surface mounted.
  • When the outer covering is flexible or compliant, the subassemblies may be configured to facilitate or allow flexing/stretching. For example, the subassemblies may be spaced apart or spread out such that the compliant material is able to stretch. In other examples, the subassemblies may be formed as small components or broken up into smaller components thereby reducing the rigidity of the entire system. In other examples, the wires that connect subassemblies may include some slack such that during stretching or flexing they do not become a pinch point to the flexibility of the entire system.
  • In some cases, the outer covering may be user configurable such that they select the desired subassemblies when purchasing/ordering the outer covering. In one example, the user may create a customized I/O. The outer shape may also be user configurable for example the outer covering may be form fitted to a user's hand shape (making it more ergonomic).
  • In some cases, the outer covering may be replaceable or disposable. For example, it may include a one time use disposable battery. In some cases, the outer covering may be upgradeable. For example, it may include standardized attachment points or regions where mechanical and/or electronic and/or optical systems may be connected.
  • A connection interface that may be provided between a portable electronic device and a cover (outer covering). In one embodiment, the portable electronic device includes an exposed connector on one of its outer surfaces and the cover includes a corresponding exposed connector region on an under surface configured to be placed against the outer surface of the portable electronic device. The under surface may for example be an internal surface within a cavity of the cover that surrounds the portable electronic device. Although the connector region may be placed anywhere on the portable electronic device, the connector region can be placed on the back side of the portable electronic device. Alternatively, it may be placed on the bottom side of the portable electronic device. The connector region may include one or more exposed contact pads or pins configured in a variety of layouts and shapes.
  • The various aspects, embodiments, implementations or features of the invention can be used separately or in any combination.
  • The advantages of the invention are numerous. Different embodiments or implementations may, but need not, yield one or more of the following advantages. One advantage of certain embodiments of the invention is that a cover having one or more electronic components embedded therein can serve to extend or augment capabilities of a portable electronic device being covered by the cover. For example, the one or more electrical components provided in a cover can be used (i) to extend input/output capabilities of the portable electronic device, (ii) to augment functional capabilities of the portable electronic device; and/or (iii) to associate ornamental aspects to the portable electronic device.
  • The many features and advantages of the present invention are apparent from the written description. Further, since numerous modifications and changes will readily occur to those skilled in the art, the invention should not be limited to the exact construction and operation as illustrated and described. Hence, all suitable modifications and equivalents may be resorted to as falling within the scope of the invention.
