Main scan pulses are applied to a CCD charge accumulation type linear photosensor array to effect horizontal scan of a linear portion of a light image of an original document focussed on the array. The document is moved by one increment each time the array is scanned to effect vertical scan. Scanning is performed intermittently under control of a run length encoder. The main scan pulses are delayed while the document is moved by one increment when the encoder causes scanning to begin.

An original document for facsmile transmission or the like is fed over a horizontal transparent platen by rollers for scanning. A light source illuminates the document and a mirror reflects a light image of a linear portion of the document perpendicular to the direction of movement horizontally to a converging lens. The light image from the lens is reflected upwardly by another mirror onto the light receiving surface of a linear photosensor array. The light receiving surface of the array faces d...

For facsimile transmission or the like an optical system scans an original document and produces quantized electrical signals which are stored in a buffer memory. A data compression unit reads out the signals and performs data compression thereon asynchronously with storage of the signals in the buffer memory. The data compression rate decreases in accordance with the proportion of high density areas of the document, and the electrical data signals accumulate in the buffer memory. The scanning s...

An apparatus for the Optoelectronic Measuring of the rotational speed of a shaft, and in particular the rotational speed of a shaft of a turbosupercharger which is part of an internal combustion engine. This apparatus makes it possible to measure the rotational speed of such a shaft in a simple, reliable, and cost-effective manner by utilizing an amplitude modulated pencil of light which is converted into a usable electronic signal by a special electronic evaluating system. The light modulator i...

Insulator circuit comprising an optoelectronic coupler consisting of a photoemitting diode positioned facing the photodetector, a photoemitting diode polarizing circuit, a signal input connected to the photoemitting diode and an output amplifier connected to the photodetector, wherein the photoemitting diode polarizing circuit comprises a high frequency power supply connected to a high frequency transformer and a rectifier circuit inserted between said transformer and the photoemitting diode.

A workpiece fed to a stitching point of a sewing machine, consisting of one or more layers of fabric, is transluminated by a source of visible or infrared radiation which is intercepted by two photoelectric sensors following each other in the direction of motion. The sensors work into respective radiation/frequency converters whose output voltages, after rectification, are compared in a window discriminator to provide an indication of the passage of a leading or trailing edge of a fabric layer m...
