Title: Video telecommunication system and method for compressing and decompressing digital color video data
Inventor: MUSIC JOHN
IPC: H04N9/808
Filed: 1989-03-23
Granted: 1993-10-12
Abstract: ABSTRACT OF THE DISCLOSURE             The method and system of compressing and decompressing digital color video data in a video communication system utilizes a digital color video signal having three video color components, and involves the determination of a predetermined number of the most visually significant combinations of color components in a picture frame, and the encoding of the color components as compressed color codes in a series of run length and compressed color code combinations. Line-to-line differ-ences and movement of edges and segments of the picture frames are determined, and frame-to-frame differences are also encoded to reduce the amount of information to a minimum. Further statistical  encoding of at least a portion of the run length and color code combinations is also  provided. The digitally compressed color component codes are decoded according to a look up table to form a table of the three digital color components for each run length, and the run lengths and corresponding color components are stored in an array in a buffer memory to represent the scan lines in a video picture frame.

Abstract: COMBINATION INFRARED AND AIRBORNE DRYING OF A WEB                      ABSTRACT OF THE DISCLOSURE        Method  and device in a drying of a moving web, in which the web is passed while being supported free of contact through various drying gaps in which the web is dried by infrared radiation and air blowing.  The web is passed into an infrared treatment gap in which infrared radiation is applied to the same, preferably from gas-operated infrared-radiation elements.  Cooling air of the infrared unit is blown into the treatment gap and towards the web.           After the infrared treatment gap, the web is immediately passed into an air drying gap within which the web is dried by way of air blowings which, at the same time, support the web free of contact.           The cooling air and possibly combustion gases from the infrared unit are passed through a web inlet opening of the airborne web dryer unit into an interior of the box of the airborne unit to constitute part of its circulating air.  The cooling air required by the infrared unit is passed into the infrared unit out of a pressure compartment of the airborne unit.

Abstract: To provide an adequate dc supply to the electronics of a telephone, when on hook or off hook, there is a transistor (T2) with its emitter-collector path in one line wire, and a storage capacitor (Cpsu) across the input to the telephones's circuits. This capacitor is charged up and maintains dc supply when the line voltage (at A) falls below a preset level. The base of this transistor is connected via another transistor (T1) to the other line wire. The speech output (VIN) is connected via an operational amplifier (A) to the base of the second transistor (T2). Hence the dc supply and the speech output are in parallel.

Abstract: A smoke detector is disclosed having a radiation source operated in a pulsed mode. Externally of a direct radiation region of the radiation source there is arranged a radiation receiver which, in the presence of smoke or other particles emanating from a combustion process and located in the radiation region, is impinged by scattered radiation and delivers an output signal to an evaluation circuit. The evaluation circuit contains switching elements which, when the number of source output signals or pulses exceeds a predetermined threshold value for the number of source output pulses, delivers an alarm signal. Near to the radiation receiver there is arranged a reference cell in the direct radiation beam of the radiation source, this reference cell controlling the emission of radiation by the radiation source. Further, there is provided circuitry which, in the presence of a slow change in the amplitude of the receiver output pulse, adjusts an amplitude threshold value set for the amplitude of the receiver output pulse at a rate corresponding to a time-constant of more than one minute. Consequently, there is obtained an output signal of the radiation receiver which is dependent upon the smoke density and which is independent of the contamination or soiling of the smoke detector.
