Title: Signal processing system for laser detector - includes logarithmic amplifier to reduce effect of large signal changes
IPC: G01S7/486
Filed: 1977-01-19
Abstract: The signal processing system is especially for the output signals from laser detectors to reduce the effect of large signal charges from false target information. Two detector output signals with a large momentary dynamic range are fed into separate signal chains each containing a logarithmic amplifier. The signal equivalent to the logarithmic value of the detector signal is passed through a processing circuit that considers the difference in these signals. The output from this circuit gives a signal with a polarity that indicates which of the two signal chains has the higher output. The circuit contains preamplifiers having a bandwidth of 25 MHz. Linear summing amplifiers each with a bandwidth of 25 MHz. Linear summing amplifiers each with a bandwidth of 35 MHz are followed by logarithmic amplifiers, scanning components, a differential amplifier, and a limiter. The output of the OR gate is connected to an automatic control circuit.

Abstract: ABSTRACT OF THE DISCLOSURE A document/copy carrying drum of a facsimile transceiver is rotatably driven by a synchronous motor.  The synchronous motor is connected as a load in series with a first transistor and a first power supply of one polarity. The synchronous motor is also connected in series with a second circuit and a second power supply of opposite polarity so as to apply DC voltages of opposite polarity during alternate conduction of the transistors. Conduction of the transistors is controlled by alternately applying a series of relatively low voltage pulses to the bases of the transistors through high frequency isolation transformers.  The pulses are separated by a time interval less than the base storage time of the transistors so as to assure continuous conduction between the collector and emitter of a transistor while a series of pulses is applied to the base thereof.]

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to stereophonic micro-phones.  In the stereophonic broadcasting and recording of sound, it is necessary to have the sound from the left side separately recorded and reproduced from the sound from the right side.  This is often accomplished with spaced microphones, but it is often difficult for the amateur or the hobbiest to position and maintain micro-phones in spaced relationship when he wishes to make a stereo recording.  It is often possible to secure a com-parable result if two microphones, both directional, are placed back to back so that each microphone receives sound coming from a different direction.  Preferably, the microphones should be separable from each other, so that, when desired, the microphones can be separated and spaced apart so that they may record in the normal stereophonic manner.  The present invention comprises a microphone assembly making use of a pair of microphones that are mechanically, but releasably held together.  Each of the microphones has similar acoustic and electrical character-istics and each has directivity characteristics such that it responds to sound coming to it from only one side.          One form of microphone having such a directivity character-istic is often referred to as a cardioid microphone.  The means holding the two microphones together may be of any suitable type, such as a simple mortise and tenon or dove-tail slide.

Abstract: (S76P108) VIDEO TIME BASE CORRECTOR                    ABSTRACT OF THE DISCLOSURE          In a time base corrector which converts incoming video signals to digital form and writes the digitized signals in sequentially enabled units of a main memory at a clocking rate varying generally in accordance with time base errors in the incoming signals, whereupon the signals temporarily stored in the memory are read out or fetched from the successive main memory units at a standard clocking rate and reconverted to analog form for eliminating the time base errors: a drop-out memory stores drop-out information in respect to drop-outs detected in the incoming video signals written in each of the main memory units; drop-outs are eliminated in the output from the time base corrector by rewriting, in each memory unit storing video signals having drop-out as indicated by the drop-out memory, video signals from another memory unit shown by the drop-out memory to be free of drop-out, with such rewriting being effected simultaneously with the read out of the video signals from such other memory unit; and upon the rewriting of video signals in a memory unit, the stored drop out indicating information in respect to that memory unit is erased from the drop-out memory.  Further, the clocking rate for reading out the video signals from each of the main memory units is modulated in accordance with velocity error information stored in a velocity error memory during writing of such video signals in the respective main memory unit, and the velocity error memory is operative, upon rewriting in a main memory unit for eliminating drop-out, to replace the velocity error information stored in respect to such main memory unit with the velocity error information associated with the main memory unit from which the rewritten video signals are drawn.
