摘要： A ratcheting micromotor includes a ratchet bar defining ratchet teeth along an edge thereof, and first and second ends in opposition to one another. The first end is adapted to be coupled to an object to be moved. A spring is coupled on one end thereof to the second end of the ratchet bar and adapted to be fixed at another end thereof to a base. A bi-directional actuator configured for linear movement in one of a first direction and a second direction, and when energized has a common yoke coupled to a central portion thereof for movement in correspondence therewith. The common yoke includes teeth formed along an edge and positioned such that its teeth engage a portion of the ratchet teeth. A control system energizes the bi-directional actuator to move, alternately, in the first direction and the second direction.

摘要： A system for protecting a diaphragm of a microelectromechanical systems (MEMS) device includes a housing coupled to the MEMS device such that its sensing diaphragm is surrounded thereby. A perforated barrier in the housing is adjacent to the sensing diaphragm. A protection diaphragm in the housing has its first side exposed to an external environment of interest, and has its second side facing the perforated barrier and spaced apart therefrom. A fluid is disposed contiguously between the second side of the protection diaphragm and the sensing diaphragm.

摘要： Systems and methods for a self-regulating power supply for MEMS thermal actuators to achieve maximum actuator displacement while preventing over powering. The present invention includes a power supply configured to regulate electrical input power to a MEMS thermal actuator in order to provide the maximum possible electrical input power. Accordingly, the present invention provides a maximum actuator displacement while preventing device failure from over powering. The present invention utilizes resistivity versus temperature properties for silicon or the like to provide a self-regulating power supply that can be utilized to power a variety of MEMS components without requiring custom actuator control circuits for each type of component.
