Abstract

The device 10 includes a liquid filled bellows activated battery composed of two non Miscible fluids 14, 15 flowing through a channel 13 containing two electrodes 16, 17 of different metals. One of the fluids 14 is an electrolyte while the second 15 one is electrically non conducting. At rest the two electrodes 16, 17 are in the non conductive fluid 15. When the electrical device is actuated, manually or by an external force, the fluids surrounding the electrodes 16, 17 are replaced by the electrolyte 14 thus generating an electrical voltage between the two electrodes. The electrical current can be used to temporarily generate light or supply energy to another device. When the actuation mechanism is released, the electrodes 16, 17 are surrounded by the non conductive fluids 15 again and the electrical current is stopped.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The following description is not intended to limit the scope of the invention in any way as they are exemplary in nature, serving to describe the best mode of the invention known the inventors as of the filing date hereof. Consequently, changes may be made in the arrangement and/or function of any of the elements described in the exemplary embodiments disclosed herein without departing from the spirit and scope of the invention.
Referring now to FIGS. 1A and 1B, an electrical device 10 is provided which functions as a switch, and, optionally, as a battery. The electrical device 10 functions independently as a switch in one variant. In another variant, the electrical device 10 functions as a battery/switch combination. In yet a further variant, the electrical device 10 functions as a combination switch and battery. It is appreciate that a system is also described with one or more (e.g. a plurality of) electrical devices 10 provided. As such, a plurality of independent switches are provided in the system, as well as a plurality of independent batteries, which can optionally function in an electrical circuit, and be used to actuate one or more other devices or portions of a timepiece.
The device 10 is made up of a tubular housing 12 (one or more housings are also used herein), made of insulating material, and flexible end structures 20 and 30 which close the one or more tubular housing(s). The tubular housing 12 defines a substantially unobstructed capillary channel and has two electrodes 16 and 17 (although the invention, in one variant, may use a plurality of electrode pairs) and contains non miscible fluids 14 and 15 (in another variant of the invention, several sets of non-miscible fluid pairs are used) and a meniscus 19 therebetween (optionally, where several sets of non-miscible fluid pairs are used, a plurality of menisci are provided). One of the fluids (or of the optional fluid pair) is a conductive fluid 20 (e.g., mercury, or an ionic fluid) and the other of the fluids (or of the optional fluid pair) is a non-conductive, non-ionic fluid 30 (and can be, optionally, one or more gases, in another variant of the invention). In another variant, the invention uses fluids which are non-toxic, and/or non-mercury containing. A user is provided with means for displacing the meniscus 19 (or multiple optional menisci) across the electrodes 16 and 17 (or the optional electrode pairs) to open or close a current path therebetween. Optionally, the two electrodes are made out of metals or metallic conductors different in composition from the electrolyte, such that when the electrolyte is in contact with both electrodes, the switch functions as a battery. Various electrode and electrolyte compositions are used herein, and in the system described above, combinations of different electrolyte compositions and electrode pairs are used to provide varying switch capability within the system.
In one embodiment, the flexible end structures are bellows 20 and 30. In another variant a plurality of bellows pairs are used in the system of the invention, each providing different functionality to various sub-systems within the system, e.g. including switching capability and energy generation capability. Various types of bellows are used in the invention, and in one variant, the bellows 20 and 30 are sized, constructed and dimensioned as accordion shaped structures. These structures have the benefit of moving the fluids through a sufficient distance to enable the functionality of the entire system efficiently in a very compact configuration. The bellows 20 and 30 are actuated to move the meniscus 19 to one or the other side of the electrodes. In a variant, a plurality of menisci are moved through an essentially unobstructed, single channel across various set of electrode pairs. In another variant, a plurality of menisci are moved through a plurality of channels in the system. In yet another variant, a single sub-system includes a single meniscus and movement of the meniscus within a single channel, alone or in combination, with another sub-system that includes a plurality of menisci moving through a single channel as described herein. Hence, various structural configurations of the system support these variants, as well as various methods of the invention described herein, e.g. include methods of energy generation and/or methods of switching, alone or in combination using one or more of the sub-systems described herein.
In one embodiment, the bellows 20, 30 are made of a metal or a metallic material, such as, by way of example, nickel or Nitinol®, which enhances the perception of quality of the device 10 and functionality of device 10. Nickel Titanium (NiTi) is in the class of shape memory alloys which may be used in the present invention. A thermoelastic martensitic phase transformation in the material is responsible for its extraordinary properties. Nitinol™ properties include the shape memory effect, superelasticity, and high damping capability. These technical properties of NiTi shape memory alloys can be modified to a great extent by changes in composition, mechanical working, and heat treatment to obtain different properties of the bellows described herein. Shape memory is a property of select materials that have the ability to “remember” the shape given during original thermo-mechanical processing allowing the material to revert to that original shape when subjected to heat. Other memory shape alloys used in the invention include copper-zinc-aluminum-nickel and copper-aluminum nickel. Materials with shape memory properties allow for the creation of lightweight solid-state devices that would otherwise require the use of mechanical systems.
However, the bellows 20, 30, of course, is constructed of any suitable flexible and water tight material such as a polymer or polymer composition, a rubber or other elastic material. It is appreciated that when the system of the present invention is used in a wrist watch, the various components are sized and dimensioned to be accommodated within a very compact space.
In one embodiment, the tubular housing 12 is a capillary tube. One or more tubular housings are provided in various sub-systems of the invention. The capillary tube 12 has a microfluidic or capillary channel 13, through which the fluids may be actuated. As is appreciated, that the variants of the systems and sub-systems of the present invention include a plurality of independent capillary channels.
In an alternate embodiment, the meniscus 19 between the fluids is actuated by a flexible end structure in the form of a membrane. Of course, in each respective sub-system, a respective membrane is utilized, and a plurality of membranes reside in a plurality of similar sub-systems of the system described herein.
In the variant of the invention that functions as a battery (of course one or more sub-systems are also contemplated to provide a plurality of battery, e.g. power source capability variants), the electrodes 16 and 17 are made of a zinc material and a copper material, respectively, e.g. a zinc alloy and a copper alloy, and/or a zinc containing conductive polymer composition and a copper containing conductive polymer composition. The electrodes 16, 17 extend into the channel 13. Alternatively, the electrodes 16, 17 are in a chamber (not shown) larger than the channel 13. Of course, various metal and metal derivative and electrolyte compositions, and combinations thereof, may be used in various sub-systems of the present invention.
The device 10 may be actuated manually by a user or automatically actuated by one or more other sub-systems or systems utilized in the present invention. However, alternatively, an external mechanism, such as a mechanical timer or a plunger (not shown) against which a user can compress a bellows which is elastic enough so as to spring back to a rest position (in the battery embodiment, with the switch open i.e., the non-conductive fluid surrounding at least one electrode and therefore electrically isolating it from the other electrode).
In one variant, the device 10 is used to power an LED 18 (of course, a plurality of LEDs is also energized in other variants of the invention) to generate light to a watch face or to illuminate a florescent fluid filled display. Alternatively, the electrical power generated is used to actuate an external circuit or to supply an external device, alone or in combination with, the LED effects on the watch. One or more LEDS are used in the system of the invention, powered and switched by one or more sub-systems of the invention.
Referring in particular to FIG. 2, in another variant, the device includes several pairs 40 of electrodes in parallel. In this embodiment, capillary channels 13 are provided that include several separate channels (which assume locations within the system parallel to one another, or in stacked arrangements, or across the interior of a timepiece in a variety of geometric arrangements, e.g. parallel, crossed arrangements, etc.) which connect two distal reservoirs (of course, a plurality of reservoir pairs are also used in a variant of the invention). In one variant, at least two of the separate channels has a pair of electrodes. Of course a multiplicity of channels are also provided in a variant of the invention with a multiplicity of electrode pairs.
Referring in particular to FIG. 3, in one embodiment, the device 10 of the invention includes several pairs of electrodes in series in a single sub-system. In such an embodiment, the tubular channel 13 is filled with successive portions of the two fluids alternatively, thus having several menisci 19. Of course, in another variant, a plurality of sub-systems of FIG. 3, alone or in combination, with the other sub-systems described herein are also provided providing increased functionality of the entire system.
Referring now to FIG. 4, progressive views of the actuation of a bi-stable plunger 100 are shown. As can be seen from this progression, the plunger 100 presses against a bellows 20 or 30, thereby compressing it. Once a user releases the plunger 100, the duration of the activation is then driven by the spring rate of the bellows 20 or 30 limited by a fluidic resistance of fluid flow through the channel 13. To prevent the user from continuing to press the plunger 100 and so continuing to activate the switch 10, 10′, or 10″, a bi-stable mechanism 102 (see the offset plunger 100 having a bi-stable cantilever arm 104 which acts against the bellows 20 or 30, and then breaks over to free the end 106 of the bellows) is added that frees the end of the bellows 20, 30 thereby allowing it to return, even though the user's finger continues to press the plunger 100.
In one embodiment, the flexible end structures are made at least in part of glass. The tubular housing may be transparent or non-transparent, and be constructed of a fully transparent material or a partially transparent material, or of a partially non-transparent or fully non-transparent material depending on the desired functionality of this component of the system or sub-system. In an advantage, the invention provides a reliable electrical switch. In another advantage, the invention provides a battery that has an innovative appeal so as to be suitable for a luxury product. In another advantage, the invention provides a combined switch and battery that fulfills both the above-mentioned needs, simultaneously, intermittently or as controlled by circuitry.
As is appreciated, the invention provides a timepiece comprising the electrical device described herein, and a method of operating at least a portion of the timepiece that includes displacing a meniscus across electrodes to open or close a current path therebetween. The method of operating a timepiece includes an electrical device. The electrical device includes a tubular housing and flexible end structures which close the tubular housing. The tubular housing has two electrodes and contains non miscible fluids and the meniscus therebetween. One of the fluids is conductive and the other of the fluids is non-conductive.
Other features are also used, in combination, with the invention described herein.
By way of example, a visual indicator display device is used in combination with the invention and includes a bracelet, a transparent capillary chamber, and a displacement member. The transparent capillary chamber is matched to an indicia and has a primary length and a width less than the primary length. An analog indicator of the invention indicates time.
By way of further example, the features of the invention are incorporated into a wristwatch. The watch advantageously comprises a case in a distributor with a two fluid reservoir and a pump.
The watch movement comprises a power source, for example a cylinder or a stack, a regulating member, for example a rocker assembly/spiral or a crystal oscillator, a pump, as well as transmission elements, including for example a train of gears and pinions. Other elements, including complications etc. can be provided. The power source can also activate the pump.
The pump causes the liquid from the tank in channels through the glass shows to display temporal information or other information through the watch glass. The channels typically have portions parallel to the display surface of the ice, as well as holes perpendicular to this surface and to connect the pump to the dispenser and in motion.
The geometry and dimensions of the channels in the glass and in the rest of the watch are chosen so as to allow filling without bubbles when the bubbles are undesirable. For this purpose, the narrowest crosssections of the channels are of one square millimeter, for example between 0.1 and 10 square millimeters, which allows to discharge the bubble with acceptable overpressure in the system, for example of only a few millibars overpressure. It also avoids preferably too abrupt changes in direction, such as angles, and complex or too thin geometries which can cause obstructions bubbles in narrow passages and block the flow of fluid.
The liquid (or other fluid) is preferably colored for better visibility in the channels. Clear fluids may also be used, however, they should change the refraction on the inner surface of the channels in order to make them visible when full. Liquid flows through these channels modifies the opacity and/or color of the glass in the channels where liquid is found. It is also possible to use phosphorescent liquid visible at night, for example, liquids with phosphorescent or luminescent particles.
The path followed by the fluid depends on the viscosity of the fluid of the inner walls of the canal and the pressure applied by the pump. It is thus possible to control the path traveled by and/or the flow velocity of a bubble or a drop in the working channel on the choice of surface tensions of the liquids and the wettability properties and characteristics hydrophilic or hydrophobic surfaces of the channels, and on the shape and surface condition. Preferably, no active microvalve is used in the liquid circuit.
