Abstract: An electronic switch comprises a substrate having a surface and an embedded electrode, a droplet of conductive liquid located over the embedded electrode, and a power source configured to create an electric circuit including the droplet of conductive liquid. The surface comprises a feature that determines a contact angle between the surface and the droplet.
Abstract: A switch comprises a first switch element configured to actuate by electrowetting, the first switch element comprising at least two radio frequency contacts and at least two control electrodes. The switch also comprises at least two additional switch elements configured to make and break an electrical connection between the at least two control electrodes of the first switch element.
Abstract: An electrode electrolyte system is provided that is capable of operating in slope sensors in a wide range of temperatures. The eletrolytic system is characterized by a stable conductivity at high temperature and by low toxicity. The slope sensor can be installed in a system containing an Nal solution in propylene carbonate, combined with platinum electrodes.
Abstract: A method of configuring an electrolytic tilt sensor having a plurality of non-precious metal electrodes and a common electrode at least partially immersed in an electrolyte and included within an electrical circuit with a voltage supply by maintaining the power at the electrodes of the tilt sensor below a predetermined threshold power density measured at an immersed surface of the electrodes.
Abstract: A resettable switch is disclosed having a conductor maintained in contact with a reservoir of mercury to conduct current therethrough during normal operation. During impact or roll over, the mercury is spilled from the reservoir and prevented from returning thereto by cone-shaped retainers maintained in a telescoped relation by a spring, thereby opening the switch. The switch may be reset by depressing a plunger which aligns slots in the telescoped retainers, which permits mercury to return to the reservoir.
