Abstract: A sensor device is used for sensing position of a movable component. The sensor device can be applied to multiple applications. For example, proper alignment between a shifter spline and a shifter position sensor of a transmission assembly can be confirmed by applying the sensor device of the present invention to confirm alignment of the transmission shifter with a transmission shifter position sensor during transmission assembly. A rotary sensor converts angular movement to a proportional electrical output. A converter then converts the proportional electrical output to an input which can be read. The location of the movable component is then determined, and displayed.

Abstract: A device for determining position between two parts which are movable relative to one another, comprises a linear sensor arrangement, a length scale or angle scale comprising a sequence of transparent and non-transparent fields, an illumination device and elements for imaging at least one section of the scale on the sensor arrangement. The entire length scale or angle scale is divided into n graduation portions of equal length, wherein every portion contains a sequence of transparent and non-transparent marks, and the sequence is successively a number which is binary-coded with k bits and correlated with the respective portion as rough value code and a fixedly recurring number which is likewise binary-coded with k bits as a reference mark (reference mark with length of k bits). Every code bit is of equal length and is formed of a transparent and a non-transparent field (half-bit) of equal length, wherein the binary information comes from a sequence of two half-bits. A process for relative position determination shows how the sensing of the graduation and the evaluation and determination of the measurement values is carried out.

Abstract: A digital displacement encoder that includes a mechanical actuator constructed and arranged to be displaced to one of a null and a plurality of activation positions in response to an externally-provided force. Also included is a conductive member constructed and arranged to be positioned to one of a plurality of intermediate positions in response to the change in position of the mechanical actuator. A contact array comprising a plurality of activation signal contacts is fixedly disposed proximate to the conductive member. Also included is a digital signal generator comprising one or more electrical circuits electrically coupled to the plurality of activation signal contacts, and one more terminals at which output signals are provided. The conductive member electrically contacts a predetermined one or more of the plurality of activation signal contacts when the mechanical actuator is in each of the plurality of positions. At each of the intermediate positions, the conductive member electrically alters the electrical circuits that include the contacted signal contacts to cause a change in output signals. Preferably, the conductive member is comprised of a conductive elastomeric material. Also, it is preferable that a biasing element be included to urge the conductive member toward its null position. The digital signal generator is a voltage pull-up circuit, although any type of circuit may be used. In one embodiment, the digital signal generator provides a plurality of output signals having a nominal state responsive to the mechanical actuator being in the null position, and a plurality of activation states each responsive to the mechanical actuator being in one of the plurality of activation positions. Preferably, the signal contacts are traces on the printed circuit board. The mechanical actuator may be a rocker button, wheel or slide, among others.

Abstract: A programmable system synchronizes the operation of an electronic angular position indicator with the angular displacement of a rotor. The system can synchronize operation with rotors with non-uniform mark spacing. A sensor provides the system with electronic pulse patterns corresponding to marks on the rotor. Pulse patterns are compared to patterns stored in memory to determine the instantaneous angular position of the rotor. The synchronization system provides the angular position indicator with parameters appropriate to the angular position of the rotor. The system obtains synchronization during initial rotations of the rotor and continually checks synchronization during subsequent rotation.
