摘要： In the normal rotation direction, a change in the main sensing signal caused by a front edge is defined as a signal change caused by an effective edge, and a change in the main sensing signal caused by a back edge is defined as a signal change caused by an ineffective edge. In the reverse direction, a change in the main sensing signal caused by the back edge is defined as a signal change caused by an effective edge, and a change caused by a front edge is defined as a signal change caused by an ineffective edge. Regardless of the rotation direction, a detection signal generating circuit generates a detection signal including falling-edge changes and rising edge changes caused by the effective edge and ineffective edge respectively. When the direction is changed, the signal change on the detection signal is prohibited. As a result, gear tooth detection discrepancies are prevented.

摘要： Disclosed are various embodiments of a single track reflective optical encoder featuring increased spatial resolution, reduced cross-talk between adjoining photodiodes, and increased amplitude output signals from individual photodiodes. With respect to prior art single track optical encoders, some photodiodes are removed from a photodiode array, while nevertheless maintaining appropriate phase relationships between pairs of A and A\, and B and B\, photodiodes. Such a configuration of photodiodes results in increased inter-photodiode spacing, and thereby permits spatial resolution to be increased while boosting current outputs from individual photodiodes. The single track optical encoder configurations disclosed herein permit very high resolution reflective optical encoders in small packages to be provided. In addition, the single track configuration reduces problems with misalignment between code scales and light detectors, permits relatively simple electronic circuitry to be used to process outputs, and reduces manufacturing, assembly, integrated circuit and encoder costs. Methods of making and using such optical encoders are also disclosed.

摘要： A rotation detection sensor for detecting both rotational position and direction of a rotating body with a gear includes a magnet, multiple magnetic sensors, a rotational position detection circuit, and a rotational direction detection circuit. The magnet produces a magnetic field directed to a gear tooth of the rotating body. When the rotating body rotates, the magnetic sensors output sensor signals shifted in phase from each other. The rotational position detection circuit performs a differential operation on the sensor signals received from at least two magnetic sensors and outputs a rotational position signal. The rotational direction detection circuit outputs a rotational direction signal based on the position signal and the sensor signal received from at least one of the at least two magnetic sensors.

摘要： A phase difference type resolver is adapted such that a calculator calculates an angle from a phase difference at a detection-signal zero cross point, determines a velocity at the angle based on an angle calculated from a phase difference at a previous detection-signal zero cross point, calculates an estimated angle at a next detection-signal zero cross point based on the velocity, divides a difference between the estimated angle and the angle into predetermined minimum detection angles, and outputs a real-time signal based on the minimum detection angles in a range after the angle but before the estimated angle.
