Abstract: An optical encoder includes a coding element having a track with a track pattern that comprises multiple optically distinguishable sections. The optical encoder compares photodetector outputs with transition-specific thresholds that correspond to transitions between the optically distinguishable sections of the track. The comparisons are used to determine when the transition between two optically distinguishable sections of the track has passed the photodetector. Knowledge of the transition between two optically distinguishable sections is then translated into digital position information.

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: This invention describes encoding methodology for the encoder assembly 18 which senses position of a shift motor 14 in a shift system 10. The basic motivation is robust operation of the shift system 10 in the event of an open circuit (OC) fault in the encoder output signal bus 20 or any fault in the encoder power supply line 80. It is assumed here that the controller 40 is unable to detect the said faults in a manner that is direct and independent of the sensed position code. The most important aspect of the encoding scheme is that the likely motor positions (main-stop positions) should be assigned as many logically high bits as possible. Next, no main-stop position should look like either Neutral or any of the two adjacent positions when an OC fault takes place in the bus 20. Finally, no position in the complete range of the travel of motor 14 should possess code which is identical to the power loss code (all logical zero's).

Abstract: An optical sensor in which both analog and digital techniques are employed. The sensor comprises an encoder and a detector. The encoder includes a plurality of tracks extending along a sensing axis. Each track has a property that varies along the sensing axis, such that the property can have one of three or more distinguishable levels. The detector detects the levels of the tracks at a position along the sensing axis, and produces corresponding output signals. The levels vary in a manner such that the output signals encode the position of the encoder with respect to the detector. The levels may vary in steps or continuously. For stepwise variable tracks, preferably only one track changes its level at any given position, and all changes in level occur in single steps. Both optical and electrical implementations are described.

Abstract: A capacitive type measuring apparatus comprises first and second electrode arrays mounted on first and second support members which are relatively displaceable with respect to each other. The first electrode array comprises a series of discrete first electrodes uniformly spaced with a pitch P.sub.r defining a scale wavelength and the second electrode array comprises a series of discrete second electrodes arranged so as to define a plurality of electrode groups each having N electrodes, where N is an integer greater than 2. The second electrodes forming each of the electrode groups are positioned within the respective groups so as to respectively occupy predetermined group positions which are distributed over a distance spanning more than one scale wavelength such that each of the group positions corresponds to the relation position of a different one of a set of relative scale wavelength segment positions obtained by dividing the group into intervals corresponding to the scale wavelength, and dividing each interval into N equal segments.

Abstract: A displacement detector in accordance with the present invention detects the amount of displacement of an object to be measured. Sensing means are arranged side by side with predetermined spacing whose states change in response to the changes in electromagnetic energy such as light energy, magnetic energy, and electrical energy. An electromagnetic energy generating means and an electromagnetic energy transmitting means that is linked to the motion of the object to be measured, transmits the electromagnetic energy from the electromagnetic energy generating means to the sensing means that is situated at the position that corresponds to the displacement of the object to be measured. A conversion unit ouputs the detection signal obtained from the sensing means as a displacement detection signal, by converting the detection signal to a coded signal that is characteristic of the position of the sensing means for the position where there was a change in the electromagnetic energy. A trouble shooting unit diagnoses malfunctions by examining whether or not the change in the displacement detection signal is within the range of specified values. A rotation number measuring unit counts the number of rotations of the object to be measured based on the detection signal from the sensing means, and a maximum value screening unit screens the maximum value from among the sensor outputs when the electromagnetic energy is incident upon a plurality of sensing means.

Abstract: An instrument for measuring the relative position of two objects comprises a scale with an incremental graduation defining a measuring direction X. A plurality of identical reference marks are positioned along the graduation, each reference mark allocated absolutely to the graduation. To determine the absolute value of a reference mark, two successive spacings between the two reference marks preceding in the measuring direction X are determined. The two spacings are determined by scanning the incremental graduation.

Abstract: A system for distinguishing identical reference marks located on a graduation used in an instrument for measuring the relative position of two objects. An individual code mark, comprised of multiple code mark elements, is allocated to each reference mark. Each code mark element can occupy one of two possible locations. A binary number associated with each code mark is obtained during scanning of the reference marks and code mark elements. The binary number is generated from a stored raster by a decoding unit and is dependent upon the position of each code mark element, the spacing between adjacent code mark elements and the spacing between the reference mark and an adjacent code mark element.

Abstract: A mechanical dial indicating gauge or meter that, without mechanical loading, optoelectronically detects and encodes the pointer position as a digital signal by use of a technique of distributed point position latching. Counter means drives a circuit which cylically sequentially lights LED's along a scale and the count is latched that corresponds to current counter position when a detector on the scale pointer is activated during the sequential lighting. This latched count provides the digital signal of pointer position. This digital signal may then by transmitted to remote indicators, controllers, computers, and/or may be compared to preset values yielding set point outputs. An electrical lead for the detector includes a spiral loosely surrounding the pointer stem.
