摘要： A strain gauge for sensing strain is provided and includes a support substrate, and first and second electrodes supported on the substrate. The first and second electrodes include first and second capacitive plates, respectively. The first capacitive plates are movable relative to the second capacitive plates responsive to strain. The strain gauge further has an input electrically coupled to one of the first and second electrodes for receiving an input signal, and an output electrically coupled to the other of the first and second electrodes for providing an output signal which varies as a function of the capacitive coupling and is indicative of sensed strain.

The accelerometer has a central member and an outer member fixed to the substrate. According to one embodiment, a plurality of inner support arms extend between the central member and the inertia mass and a plurality of outer support arms extend between the inertia mass and the outer member to support the mass over the cavity. According to another embodiment, one or more cut out apertures are formed in the inertia mass to compensate for a channel and signal line so as to balance the inertia mass about the center of the inertia mass.

摘要： A switched capacitance detection circuit is responsive to changes in the fringing capacitance of a capacitive proximity sensor having at least one capacitive sensor element. In cases where the sensor has a single sensor element, the switching frequency of the detection circuit is controlled to maintain measurement accuracy in the presence of sensor moisture while minimizing power consumption and electromagnetic radiation. In cases where the sensor has multiple sensor elements, the capacitance values for each sensor element are differenced, absolute-valued and summed to form an output in which common-mode effects due to sensor moisture, temperature and sensor aging are canceled out.

The accelerometer has a plurality of fixed electrodes supported on a substrate and fixed capacitive plates arranged in first and second sensing axes. An inertial mass is suspended over a cavity and includes movable capacitive plates arranged to provide a capacitive couplings with the fixed capacitive plates. The inertial mass is movable relative to the plurality of fixed electrodes. The accelerometer has a plurality of support arms for supporting the inertial mass relative to the fixed electrodes and allowing movement of the inertial mass upon experiencing acceleration along the first and second sensing axes. The accelerometer further has inputs for receiving input signals and an output for providing an output signal which varies as a function of the capacitive coupling and is indicative of sensed acceleration.

摘要： A band-gap reference voltage is developed by a phase-clocked band-gap circuit including a single PN junction through which first and second constant currents are alternately directed. A current proportional to absolute temperature is selectively added to one of the first and second constant currents to curvature-compensate the developed band-gap reference voltage. The band-gap circuit is calibrated at any desired temperature by interrupting the curvature compensation current and trimming the one constant current to bring the un-compensated band-gap reference voltage into correspondence with a nominal band-gap voltage functionally related to the calibration temperature and circuit component values.

摘要： An extruded capacitive sensor assembly includes multiple sense conductors of unequal length disposed in an upper section of a non-conductive jacket, and a ground conductor disposed in a lower section of the jacket adjacent a panel or carrier to which the strip is affixed. A sensor strip with three sense conductors is formed by extruding a non-conductive jacket having first and second sense conductors in the upper section of the jacket, and severing the first sense conductor to create three unequal length sense conductor segments. Electrical termination to the sense and ground conductors can be made at the point where the first sense conductor is severed, or at the end of the sensor strip. In cases where only two sense conductor segments are needed, the third sense conductor segment is removed or simply un-used.
