摘要： An arithmetic unit for correcting a detection output of a detector for a mechanical error of the detector in accordance with a predetermined input/output characteristic (straight line) is provided. When a digital output of the detector exceeds an upper limit value stored in a main memory, the digital output becomes a new upper limit value. From a virtual line which passes through the new upper limit value and which is parallel to the straight line, a new lower limit value is obtained. A corrected operation output is obtained in accordance with a new input/output characteristic of the detector based on the new upper limit value and the new lower limit value. Thus, the correction accuracy is improved.

摘要： An optical system is provided having an analog image memory, an analog refresh circuit, and analog converters. An optical image is projected on a charge transfer array, such as a CCD imaging array, generating analog image charge samples in the array. The analog image charge samples can be shifted in the array and can be processed with an analog to digital converter to generate digital samples. The digital samples can be processed with a digital processor, such as a stored program digital computer; can be processed with an analog processor, such as a stored program analog computer; and can be processed with an analog filter processor, such as a Fourier transform processor. The analog image signal samples can be refreshed to reduce signal degradation, such as with a bias refresh circuit and a scale factor refresh circuit. Adaptive refreshing can be implemented by storing a reference signal in the analog memory and refreshing the analog image signal samples in response to the reference signal.

摘要： Memory technologies for storing filter samples include RAMs and CCDs. Adaptive memory capability and memory servo capability improve memory characteristics. In a RAM embodiment, a detector is used to detect a memory address condition and to control the memory and the memory address register in response thereto. In a CCD embodiment, a detector is used to detect a memory reference signal and to refresh the memory signals in response thereto. Improved memory refresh, memory performance, and memory capacity enhance system characteristics. Improved memory architecture provides advantages of increased speed, lower cost, and efficiency of implementation. Information stored in memory can be scanned out at a rate greater than the addressing rate associated with the memories. This permits higher speed operation with lower cost memories. Use of an output buffer, such as a FIFO, permits normalization of memory clock rates.

摘要： The determination of the position of a tape thread-in and thread-out mechanism in a cassette recorder is carried out using contact paths together with a slider contact that form position switches. Output signals of the position switches are coupled via a resistor network that combines the output signals and produces an output signal on a single conductor. The resistor network output signal is coupled to an input of an analog -to-digital converter. To improve the reliability of determining the position of the mechanism without requiring the use of highly accurate resistors in the resistor network, the voltage value assigned to each individual position is measured at the output of the network during a calibration operation. The voltage values are stored in a memory and used as the desired values during normal operation.
