  • Patent number: 11042121
    Abstract: An indication device is provided. The indication device includes an elongated fluid chamber containing at least one electrically conductive liquid driven by a pump for conductive liquids and an immiscible, relatively non-conductive fluid. At least one segment of at least one fluid is used as an indicator. This segment is driven by the pump along adjacent indices of an indicator visible to an observer using a meniscus location sensor and a feedback controller so as to e.g indicate a quantity to the observer.

  • Publication number: 20190216185
    Abstract: A construct having an aesthetic form is adapted to please a wearer and to be worn by the wearer. The construct provides a structure having a wearer connection element such as a ring, a chain, a wristband, a pin, a clasp, a clip, and a body piercing element. The functional elements including a fluid reservoir in which at least two fluids are disposed, and a motion generation system are integrated on the structure, The motion generation system is functionally affixed to the structure so as to agitate the at least two fluids, causing a visual animation effect. The construct, in particular jewelry, may have incorporated therein one or more channels and/or reservoirs containing one or more fluids wherein the fluids as well as the forms and surface treatments of channels/reservoirs are selected possess physical properties so as to promote a defined interaction with the one or more fluids.

  • Patent number: 10031481
    Abstract: A drive system for energizing a device that includes a bellows actuated drive. The bellows actuated drive provides linear forward and backward movement by fluid expansion and contraction of a fluid within a reservoir according to a temperature differential while the reservoir is in fluid contact with the bellows. In one variant, two bellows are configured in a V shaped conformation. Various devices are driven using the drive system of the current invention and include a timepiece, a medical device, an implantable medical device, a cardiac rhythm management device, a hearing aid, a medical micro-injector, a sensor, and a biometric transmitter.

  • Patent number: 9978548
    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.

  • Publication number: 20160209810
    Abstract: An energy storage and release system and/or time piece device includes two elastic bellows in fluid communication with one another and filled with a single fluid or different fluids (whether liquids alone or in combination with a gas) thus allowing mechanical power transmission. The energy which loads the system comes from an external winding system (which can be performed either manually or automatically). The winding or loading force is transmitted by a mechanism attached to one or the other fluid reservoirs. As the system is loaded, the fluid contained therein expands and contracts the fluid reservoirs. The fluid reservoirs are elastic and so, once a reservoir is filled or contracted, then when the energy input from the mentioned manual or automatic winding is removed, the system will elastically seek to return to an unstressed or relaxed state, and thus release energy that is stored.
