Abstract: A transmission shift position sensor that is adapted to provide an indication of the position of a transmission shift lever. The transmission shift position sensor includes a rotary position sensor and a rooster comb formed as an assembly. The direct coupling of the sensor to the rooster comb provides a positive indication of the automatic transmission shift sensor without the need for compensating for tolerances in mechanical linkages.

Abstract: A self-lubricating bearing and more particularly to a self-lubricated bearing which includes a race and a bearing element forming two mating bearing surfaces. For applications in which the bearing may be subjected to environmental conditions that could result in corrosion, one bearing surface may be formed from a corrosion resistant metal, such as stainless steel, while the mating bearing surface is homogeneously formed with the bearing element from a composite material which includes PFTE or Teflon. By homogeneously forming the bearing element from a composite material which includes Teflon, wear of the bearing element will not effect lubrication of the bearing.

Abstract: A compensation circuit for compensating for switching point errors in rotating target or gear tooth sensors. The compensation circuit may include a processing unit and a persistent storage device, such as an electrically erasable programmable read-only memory (EEPROM), for storing compensation values that are used to provide automatic compensation of the rotating target sensor after the sensor module is installed by the end user. The actual and compensation values may be determined and stored as linear functions in the form of mX+b, where X is the frequency of the rotating target, m is the slope and b is the y-intercept. In order to provide compensation, the actual slope value m is multiplied by a compensation value. The y intercept (i.e. b) is selected, for example, to be the maximum speed in a given application. The compensation values (i.e.

Abstract: A rotary position sensing assembly (10) includes a sensor (12) that monitors angular position, and which is fixedly attached to a first member (14), and a first arm (16) having a first end (18) pivotally attached to the sensor (12) and a second end (22) including a first portion (24) of a universal joint (26). The rotary position sensing assembly (10) also includes a second arm (28) having a first end (30) that includes a second portion (32) of the first universal joint (26) pivotally attached to the first portion (24) of the first universal joint (26), and a second end (34), including a first portion (36) of a second universal joint (38). The rotary position sensor assembly (10) further includes a second portion (40) of the second universal joint (38) fixedly attached to a second member (42) and pivotally attached to the first portion (40) of the second universal joint (38).

Abstract: A mechanical linkage assembly, which includes one or more mechanical devices, such as ball joint assemblies, over molded around one or both opposing ends of a connecting rod. The connecting rod is formed with a reduced diameter portion to enable the mechanical device to rotate relative thereto, while limiting axial movement therebetween. In such a configuration, the same tooling can be used even though the length of the connecting rod changes, since the mechanical devices can be molded one after the other on the ends of the connecting rod which reduces the cost and complexity of manufacturing the assembly.

Abstract: A rotary position sensor which includes a molded housing with a central aperture forming a drive arm cavity, a drive arm assembly and a rotor plate. The drive arm assembly carries a circular magnet and a shunt ring and is rotatably received within the drive arm cavity. The drive arm assembly is formed with an extending stud for connection to an external mechanical lever. The rotor plate is used to close the drive arm cavity and carries a magnetic flux responsive element and one or more flux concentrators and optional flux shunt. The molded housing, drive arm assembly and rotor plate are configured to minimize air space within the drive arm cavity after the sensor is assembled. By minimizing air spaces within the drive arm cavity, the amount of ice build up within the drive arm cavity is minimized. In addition, to further prevent a condition of ice lock of the drive arm assembly relative to the molded housing, all surfaces within the drive arm cavity are formed as smooth surfaces.

Abstract: An electronic circuit for automatically compensating for errors in the output signal of a displacement sensor. The electronic circuitry includes an analog to digital converter for converting an analog output signal from a linear displacement type sensor. The digital output signal from the sensor is processed by a microcontroller which automatically compensates for errors in the output signal. Ideal values, stored in an electronic memory, are used for compensation.
