摘要： Apparatus is disclosed for controlling the regulating inductance of a power supply by applying across a control winding mounted on the same core a voltage having a volt-second product proportional to the difference between a desired output voltage and the actual output voltage so that the frequency of response is the same under all operating conditions. In a preferred form, the apparatus is incorporated in a power supply having a source of DC pulses that are rectified to produce the output voltage and the volt-second product of the voltage applied across the control winding is proportional to the difference between the detected value of said pulses and a control voltage that is related to the difference between the actual output voltage and the desired value.

摘要： A displacement sensor employs an electromagnetic radiation source that generates a beam of electromagnetic radiation for measuring a feature of an object. The displacement sensor includes a displacement probe, a multi-dimensional diffraction grating and a plurality of photon detectors. A reflection surface, which is changed when the probe interacts with the object, interacts with the beam from the electromagnetic radiation source and reflects a beam from the reflection surface. The multi-dimensional diffraction grating interacts with the reflected beam and generates a pattern of diffracted beams. Each photon detector senses a different diffracted beam, thereby providing information about the state of the probe.
