Abstract: PROBLEM TO BE SOLVED: To provide a driver and a method of operating a micro- electromechanical system(MEMS) device. SOLUTION: The driver for use with a micro-electromechanical system(MEMS) device, the method for operating the same, and a MEMS device employing the driver and the method are disclosed. In one embodiment, the driver is provided with an actuation subsystem which supplies an actuation voltage for altering an angle of an optical element of the MEMS device. The driver is further provided with a bias subsystem which is coupled to the actuation subsystem, applies a bias voltage between the optical element and the actuation subsystem, thereby reduces the actuation voltage.

Abstract: A liquid electrical switch is disclosed that uses a plurality of droplets of conducting liquid to form an electrical path. In a first embodiment, at leas t a first voltage differential is used to create a separation distance between t wo droplets. The droplets are illustratively contained within a housing and surrounded by an immiscible, insulating liquid. In this embodiment, the at least a first voltage differential draws at least a portion of at least one of the droplets away from a second droplet, thus preventing electrical current from flowing from the at least one droplet to the second droplet.In another embodiment, the at least a first voltage differential is changed in a way su ch that at least one liquid droplet is made to come into contact with a second droplet, thus creating an electrical path between the two droplets.

Abstract: The present invention provides a bi-directional microelectromechanical element, a microelectromechanical switch including the bi-directional element, and a method to reduce mechanical creep in the bi-directional element. In one embodiment, the bi-directional microelectromechanical element includes a cold beam having a free end and a first end connected to a cold beam anchor. The cold beam anchor is attached to a substrate. A first beam pair is coupled to the cold beam by a free end tether and is configured to elongate when heated thereby to a greater temperature than a temperature of the cold beam. A second beam pair is located on an opposing side of the cold beam from the first beam pair and is coupled to the first beam pair and the cold beam by the free end tether. The second beam pair is configured to elongate when heated thereby to the greater temperature.
