摘要： A circuit for protecting a voltage supply to a sensor from a transient event is provided. The circuit includes at least one buffer capacitor configured to provide output during the transient event, the output substantially equivalent to output of a regulated supply during normal operation of the sensor. A method of fabrication and a sensor are disclosed.

摘要： A system is configured to monitor a received signal. In response to detecting a fault condition associated with the received signal, the system sets a fault status indicator to indicate occurrence of the detected fault condition. The system sets a state of the fault status indicator for at least a predetermined amount of time to indicate occurrence of the detected fault condition. Subsequent to setting the fault status indicator for at least the predetermined amount of time to indicate the occurrence of the detected fault condition, the system monitors integrity of the signal again. After the predetermined amount of time, in response to detecting that there is no longer a fault associated with the monitored signal, the system modifies the fault status indicator to indicate absence of the fault condition.

摘要： A first embodiment of a condition responsive capacitive transducer, such as an accelerometer (1), is shown in which an electrically conductive sensor element (14) is sandwiched between upper (10) and lower (12) electrically insulative planar substrates and mounted in sealed, spaced apart relation by patterns (16) of adhesive containing spacing elements. A second embodiment (100) includes a signal conditioning capacitor having plate portions (114r, 120b and 114s, 120c) on either side of a condition responsive capacitor to minimize errors caused by translational movement of the sensor element (114) relative to the substrates (110, 112). Circuit conditioning electronics (124) is shown mounted directly on one of the substrates (110) and the sensor is mountable directly on a circuit board. A third embodiment (200) shows differential capacitors (224, 226, 228, 230, 232, 234) for minimizing errors due to misalignment of the movable element (114) with respect to the fixed supports (210, 212). Another embodiment provides a material system for use in condition responsive capacitive transducers having refractory metal for a sensing element and glass material for a supporting substrate.
