Abstract: SET-UP ARRANGEMENT FOR A  COLOR TELEVISION RECEIVER                             Abstract of the Disclosure A service switch arrangement is provided to permit set-up adjustment of a color image reproducing kinescope in a color television receiver.  The receiver comprises a horizontal deflection circuit for providing a periodic horizontal deflection signal having a frequency synchronized by a sync signal derived from a composite color video signal, and means for deriving a receiver operating voltage from the periodic signal of a magnitude dependent upon the frequency of the periodic signal.  The switch has "normal" and "service" positions, and is coupled to respective direct voltage control terminals of luminance and chrominance channels and a vertical deflection circuit of the receiver.  In the "service" position, the switch renders the luminance and chrominance channels inoperative to couple signals, and vertical scanning is disabled, to permit set-up adjustment of the kinescope.  The sync signal is derived independent of the condition of the chrominance and luminance channels, and is coupled to the horizontal deflection circuit independent of the position of the switch, so that the derived voltage exhibits substantially the same magnitude in both "normal" and "service" positions.

Abstract: A B S T R A C T           A device employing the inherent self-torquing properties of a torque repeater to position its rotor. In the present invention, the torque repeater or synchro may have three stator windings and an output rotor.  It is contemplated that the electrical input to the device will be digital signals.  However, the invention will perform equally well with time varying or analogue input signals.  A plurality of electronic switches are connected to the stator terminals of the synchro converter and they operate under the control of a programmable switch control to short-circuit predetermined stator windings to provide the desired positional output signals.  A sectant detector connected to the stator windings detect signals on the stator windings and determines the present position of the rotor.  From this information, the desired positioning of the rotor is attained from the signals of the sectant detector.  The duty cycle drive acting in concert with the sectant detector positions the torque repeater between sectant positions.  An alternative to the sectant detector is the provision of an A/D converter used to drive the switches to allow the torque repeater to self-drive to the desired output position.

Abstract: ABSTRACT OF THE DISCLOSURE      A thermistor temperature sensing system includes a conventional comparator having a constant reference threshold voltage and a lin-earized thermistor sensor which in combination detect a limited range of desirable temperatures.  A means is also disclosed for extending the linearization of the thermistor in a piecewise manner at at least one temperature extreme where linearity typically severely deteriorates.  In a thermistor temperature sensing system, linearization of thermistor characteristics with respect to at least one temperature within the temperature extreme is achieved by utilizing circuitry which makes the threshold voltage of the conventional comparator a function of the setting of a potentiometer for a desired temperature within the temp-erature extreme to be sensed by a thermistor sensor.  The piecewise linearization technique disclosed allows easy interface with the therm-istor temperature sensing system for detection of an optimum of select-able temperatures in the extended range of linearized characteristics of the thermistor.
