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： In a method or device to sample a web movement, an incremental encoder translates the web movement into two phase-offset output signals. A quadrature decoder generates first and second digital output signals with two respective signal levels. The first output signal is designated as a forward signal and the second output signal is designated as a backward signal. An evaluation circuit outputs a control signal and has a first counter that counts a signal change of the forward signal and subtracts from the count a signal change of the backward signal. A second counter counts a signal change of the control signal. A comparator compares values of the first and the second counters. A disabling device enables the forward signal if values of both the first and second counters are the same so that the forward signal is output, and disables the forward signal if values of the two counters are different.
