Abstract: A capacitive pressure sensor (10) includes a electrically conductive generally piston shaped diaphragm (16) with a flexible base wall (26) configured to deflect (68) under pressure. The diaphragm (16) is generally U-shaped in cross section. The base wall (26) includes an upper, flat sensing surface (36) which acts a capacitive electrode. The diaphragm (16) further includes a step (54) around a radially-outermost perimeter (56) which is elevated from the flat sensing surface (36). A sensing electrode body (18) is located on top of the step and creates a capacitive sensing cavity (32) between the sensing surface (36) and the bottom surface of the electrode body (38). On the bottom surface of the electrode body (38) is formed a center, circular electrode (40) and a ring electrode (42) surround the center electrode (40). The center electrode (40) and the sensing surface (36) form variable capacitor (48) and the ring electrode (42) and the sensing surface (36) form a reference capacitor (50). A circuit (20) determines a differential capacitance between the variable capacitor (48) and the reference capacitor (50) and generates a pressure signal (52) indicative of fluid pressure (24) applied to the diaphragm (16). A spring ring (82) holds the sensing electrode body (18) against the diaphragm (16). The diaphragm (16) can be a machined metal part or a sheet metal cup (100). The sensing electrodes (40, 42) and signal generating circuit (20) can be a hybrid circuit (84).

Abstract: A control circuit for a vehicle for, e.g., chassis leveling or other purposes includes a controller (12) selectively sending drive signals to a load (14) through a switch FET (M1), and a BJT having a collector connected between the switch FET (M1), an emitter connected to ground, and a base connected to a current view resistor for short circuit protection. An over power protection FET (M2) is connected to the controller (12) and to the base of the short circuit protection transistor (Q1), with the gate of the over power protection FET (M2) being connected to the output of the switch FET (M1). A time delay capacitor is connected from the base of the BJT to ground. With this structure, if a ground fault causes the BJT to turn on, and if the drain-source voltage of the switch FET (M1) exceeds the gate threshold voltage of the overpower protection FET, the overpower protection FET is turned on, resulting in turning off the switch FET (M1) and, hence, avoidance of high power draw through the switch FET (M1).

Abstract: Linear velocity sensor and method for reducing non-linearity in the output signal of the sensor are provided. The sensor comprises a ferromagnetic housing 22 including an opening. The sensor further comprises a spool 32 disposed in the housing. The spool includes a bore 30 for receiving a slidable ferromagnetic rod 26. The ferromagnetic rod may be extendable through the opening in the housing. A magnet 28 is mounted at the one end of the rod distal from the opening when the rod is substantially inserted in the bore. A coil 50 is wound on the spool. The number of turns of the coil is arranged to taperingly increase as the coil progresses from an end of the spool proximate the opening in the housing to the opposite end of the spool. The tapering arrangement for the number of turns of the coil is selected to reduce non-linearity of an output signal of the coil indicative of linear velocity.

Abstract: A sensor (10) and method for measuring the volatility of liquid gasoline by estimating its driveability index includes a sensing element (11) having an interdigitated array of electrically conducting capacitor plates (28, 42) arranged to retain a predetermined volume of gasoline, the volatility of which is to be measured. The sensing element (11) is mounted in a vehicle to be in contact with the flow of gasoline while the engine is running so that a volume certain of gasoline is drawn between and remains within the electrically conducting plates (28, 42) when the engine is turned off. The sensing element (11) is connected to circuitry (54, 65) used to measure the change in capacitance of the sensing element (11) as a function of time while simultaneously measuring the temperature change of the sensing element (11) as the volume of gasoline retained by the sensing element (11) is evaporated over time. The measurements obtained by the circuitry (54, 65) are used in estimating the drivability index of the gasoline.
