摘要： The present invention relates to automotive interface systems and methods. In one embodiment, an automotive interface system includes a steering wheel and an integrated interpolated variable impedance array that comprises a grid of sensing elements. The sensing elements are configured to power on simultaneously and to simultaneously generate multiple currents along multiple current paths in response to sensing a touch wherein the amount of current generated by a sensing element of the grid is directly proportional to the force applied by the touch. The automotive interface system also includes an analog-to-digital converter (ADC) and a processor communicatively coupled to the interpolated variable impedance array that are configured to receive the multiple currents along multiple current paths and determine a location, a duration, an area, and a force of the touch from the multiple currents along multiple current paths.

摘要： An encoder includes a scale, a detector array that includes a plurality of detectors, and a signal processor configured to process and convert into positional information, an output signal from the detector array. The signal processor includes a first phase acquirer configured to acquire a first phase of a first modulation period from an output signal of the detector array. The encoder further includes a weighting unit configured to weight an output signal from each of a plurality of detectors using a weight in accordance with a position of the detector array. The weight is set so that in a predetermined range that contains a spatial frequency corresponding to the second modulation period in a spatial frequency response of the first phase acquirer, a value weighted by the weighting unit is equal to or smaller than a non-weighted value.

摘要： A photoelectric encoder has a scale in which a main track for detecting an amount of movement is formed in a measuring direction. The photoelectric encoder includes an origin signal generating portion provided at a part of the main track in a direction orthogonal to the measuring direction. Thereby, change in a light receiving signal due to passage of the origin signal generating portion is detected to generate an origin signal. Thus, the origin signal which is in agreement with a main signal in phase is obtained and improve the reproducibility of an origin position.
