摘要： An electronic component matching system operates in conjunction with a component transport arrangement wherein a component-carrying supply tape from which components are removed for positioning upon a circuit board in a matched manner is linearly displaced. The components are thus sequentially moved to a pick-up point whereupon a predetermined number N of components having similar operating characteristics are incorporated in the same circuit. As the component-carrying supply tape is displaced toward the component pick-up point, an electro-optical sensor detects the presence or absence of components on the supply tape and provides this information to a microcomputer controller. The stationary sensor is positioned in spaced relation from the pick-up point along the component-carrying supply tape displacement path to allow for the detection of the predetermined number of components between the sensor and the pick-up point to ensure that a matched set of N components is available on the tape for incorporation in the same circuit. If the sensor determines that less than N components are present between the sensor and the pick-up point, the microcomputer advances the supply tape to the next group of matched components to prevent components from different matched groups having different operating characteristics from being incorporated in the same circuit. This system is particularly adapted for the automatic positioning of components such as transistors and diodes having matched operating characteristics for incorporation in the same circuit.

摘要： An extended range tunable resonant circuit for use in a VHF television receiver tuning system comprises a bandswitchable inductive network connected to a low series resistance gallium arsenide varactor diode. The resonant circuit, when operated in response to appropriate bandswitching signals and tuning voltages, is effective for establishing a plurality of tuning bands collectively defining an extended sub-UHF tuning range from about 54 MHz to at least 408 MHz.

摘要： A digital video communication system includes a two-way communication link between a source and a viewer. A video program, in sequential compressed digital form, is repetitively supplied to a fifo memory that has taps corresponding to the number of fixed length segments in the video program. The program is taken from one of the taps and supplied to a one segment-long fifo memory which has taps corresponding to fields in the segment. A program request by a viewer results in the segment at which the beginning of the program will next appear to be addressed and remembered. The field fifo is reset to the first tap and the video program data is processed and transmitted to the viewer from the first field tap. Should the viewer wish to interrupt the video program, a field counter is enabled by an interrupt signal to step over the field taps (at the field rate), thus "freezing" the program. The interrupt signal also causes the address counter to count up (change tap addresses) at the segment rate. When the interruption request is removed, the normal program transmission is restored from the "frozen" field of the video program.

摘要： An all-channel television tuner includes a single 75 ohm input for receiving airborne signals and CATV signals. A single band high frequency section tunes frequencies from 370 to 806 MHz and a three band low frequency section tunes frequencies from 54 MHz through 370 MHz. Both sections are coupled to the 75 ohm input through signal diverting means. A channel selector provides tuning voltages and band switching voltages to the sections and to the signal diverting means as a function of the channel selected.

摘要： A television receiver includes automatic fine tuning, synchronous detection, and a "window" type tuning system. The synchronous detector has a detector oscillator which is tunable to the nominal frequency of an intermediate frequency signal derived from a received television signal. For fine tuning control, a frequency comparator receives the outputs of a fixed frequency reference oscillator and the synchronous detector oscillator and develops a control signal for locking the tuner to the frequency of a received television signal.

摘要： A television receiver incorporating telephone interface circuitry permitting the viewer to remotely place outgoing calls by recalling a selected number from memory is disclosed. An infrared link is used for remotely answering incoming calls, initiating outgoing calls and programming a nonvolatile memory with a plurality of preferred telephone numbers for future use. The nonvolatile memory circuit is accessed by means of a microcomputer in response to user-initiated, remotely generated commands. The television receiver's display performs a user interactive function in displaying television/telephone mode operation information, the contents of user-accessed locations in the nonvolatile memory and the telephone number being stored in memory during the programming mode of operation. The microcomputer controls not only the telephone mode of operation of the system, but also television operation in generating digital tune words in response to a channel number entry and providing these tune words to an indirect frequency synthesis type of television receiver tuner. The contents of the nonvolatile memory may be updated, or changed, as desired by user selection of appropriate controls followed by entry of the new telephone number which is presented on the video display as it is entered for user verification. The video display is then cleared upon return to the television mode of operation or upon television receiver turn-off.

摘要： A television/telephone loudspeaker system is disclosed wherein feedback oscillation caused by having a speaker phone system simultaneously in the transmit and receive mode is minimized. Improved separation of transmit and receive signals is accomplished by microprocessor-controlled dynamic balancing of a bridge network coupled to a telephone isolation transformer to which the incoming and outgoing calls are provided. In addition, by microprocessor sampling of the television receiver's loudspeaker drive voltage from the telephone input line, dynamic proportional attenuation of microphone gain (AGC) is digitally accomplished in simulating full duplex operation. Bridge balancing is accomplished by means of test signals output by the microprocessor during quiet periods with various other audio signal refinements, such as room background noise cancellation, available with the constant monitoring of the microphone signal. Audio and visual indications of an incoming telephone call are provided by the television receiver's tuning system microcomputer which detects and decodes user remote commands and activates a phone relay and phone light emitting diode (LED) drivers.

摘要： A microprocessor based TV/TTX processor includes a stored pages ROM in the TTX processor for storing on-screen display messages and lists of functions and characteristics as pages of TTX data. An RGB switch is coupled to receive the output of a character generator in the TTX processor and to receive the video output of the TV for selectively displaying information from each source with or without the on-screen messages and lists. The stored pages ROM relieves the microprocessor of the necessity of generating the on-screen messages and lists. Items on the list are controllable by the viewer and an indication of the status of the item is given by the microprocessor changing a character in the display memory of the TTX processor.
