Abstract: (1) Abstract of the Disclosure A high-definition signal, which is band-compressed by an offset sub-sampling circulating in n=4 fields, is supplied to a simple MUSE processor from an input terminal.  The simple MUSE processor generates a simple high-definition television signal is generated by super-imposing fields which are fewer than n=4 fields.  A scanning line processor converts said simple high-definition television signal into an interlaced scanning signal with a number of scanning lines which are smaller than that of the television signal of the present sys-tem.  The television signal, which is output from the scanning line processor, is converted into an analog signal by a digital-analog converter.  Two color differ-ence signals, which are obtained by the digital-analog converter, are input to a quadrature modulator.  The sub-carrier used in the quadrature modulator is gener-ated as follows a clock, which is synchronized with the sampling pulse of the high-definition television signal, is obtained from a synch regenerator.  The clock, which is obtained from the synch regenerator, is input to a phase-locked loop circuit.  The phase synch loop circuit generates the color sub-carrier, which is phase-synchronized with the clock, and supplies the color subcarrier to the quadrature modulator.  Therefore, according to the above-mentioned system, the field fre-quency of the input television signal can be set to (2) invert every frame as the field frequency of the input television signal is maintained.  Also, the frequency of the color sub-carrier can be set to be in a frequency draw-in range of a color processor of NTSC system.

Filed: 1991-07-04
Abstract: ABSTRACT           An electronic joystick is provided employing a sensor  element  to  determine  the magnitude  of translational displacement, if any, which the joystick has undergone.  A controller monitors the sensor element output and compares it to a predefined threshold value to determine whether or not displacement of the joystick has occurred.   If a displacement has occurred,  the controller examines the output of an array of additional sensor elements to determine the direction of the displacement.   The sensor elements in the array are utilized in pairs, one pair for each degree of freedom of movement.   The controller examines the difference between the output signals generated by the sensor elements of each pair to determine if a displacement of the joystick has occurred in a particular direction. Appropriate control  signals are generated by the controller representative of the direction and the magnitude of the displacement of the joystick for controlling a control device.   An additional pair of sensor elements are employed to detect rotational movement, if any, of the joystick.

Filed: 1990-05-04
Abstract: The invention is directed to an improved method and apparatus for monitoring the status of an AC electrical transmission line (101; 102, 103) connected betweeen first and second locations. In a disclosed embodiment of the method of the invention, first signal parameter values are generated, for the first location, by time integrating between zero-crossings of an AC signal parameter measured at the first location. Second signal parameter values are generated, for the second location, by time integrating between zero-crossings of the AC signal parameter measured at the second location. A stared first signal parameter value is read out, the read-out value being associated with a time that is a predetermined time prior to the time at which a second parameter value is received at the first location. An indication of the status of the transmission line is then produced as a function of the second signal parameter value received at the first location and the read-out first signal parameter value.
