摘要： A signal processing apparatus includes an adder and a weighting integrator. The adder receives a first input signal and an integrated signal, and generates a first output signal. The first output signal is obtained by subtracting the integrated signal from the first input signal. The weighting integrator receives the first output signal, and generates the integrated signal. The weighting integrator includes a weighting function generator, a multiplier, and an accumulator. The weighting function generator receives the first output signal. When the first output signal crosses a zero crossing point, the weighting function generator generates a weighting function. The multiplier performs a multiplication on the weighting function and the first output signal. The accumulator is connected to the multiplier for accumulating the product of the weighting function and the first output signal, thereby generating the integrated signal.

摘要： A method is presented for converting the sine/cosine signals from an optical encoder into a high-resolution position signal for use by a position control system while eliminating common noise and error sources. The improved noise performance resulting from the alias-free demodulation of encoder signals improves precision and reduces power consumption in precision motion control applications. The adaptive compensation of harmonic distortion eliminates errors related to offset, gain and quadrature of the encoder channels. The interpolator is able to process encoder signals at extremely high resolution without the speed limitation of prior art encoder interpolators.

摘要： A system and method for sensing position of an oscillating moving element. The inventive position sensor includes a first arrangement for sampling the position of the element at first positions thereof and providing samples in response thereto and a second arrangement for calculating other positions of the element using the sample of the first position. In the illustrative application, the first arrangement includes an LED and a photodiode and the moving element is a piston of a long-life cryogenic cooler. A processor receives samples from the photodiode and solves an equation of motion therefor. The equation of motion is P(t)=A·sin(ωt+θ)+B, where P(t)=the position of the element; A=position waveform amplitude; B=position waveform DC Offset; ω=angular frequency of operation; t=time; and θ=position waveform phase.

摘要： The present invention is based on the finding that the evaluation of the sensor signals of a position sensor with a mechanical period or, in general terms, the cooperation between position sensors and evaluation units, can be improved by eliminating divergence between the electrically optimal period and the mechanically optimal period. According to the present invention this is achieved in that the position sensor signal, which has a period which depends on the mechanical period of the scale of the position sensor, is translated into a translated signal with a period which corresponds to a second mechanical period, which e.g. has been set to the electrically optimal period, prior to—or for the purpose of—transmitting it to an evaluation unit, whereby not only can transmission errors be minimized and the evaluability improved but a complicated mechanical adjustment of the scale of the position sensor relative to the evaluation unit is avoided.

摘要： A sensor system is provided in which a digital absolute value of the particular position of a stationary part (stator) with respect to a part moving relative to it (rotor) is created, which is transferred in serial transmission to an evaluation circuitry, whereby transfer of the serial absolute value is induced each time by an external signal. In order to increase the resolution of the encoder, the change in absolute value is recorded each time in the sensor and finest interpolation is undertaken beginning each time from the time of the change. Finally, the absolute value is amended by the accumulated result of finest interpolation when interrogated by the external signal.
