摘要： An input signal for controlling a television power supply has "power-on" and "power-off" signal states. When the input signal is in the "power-on" state, it couples a clock signal to a primary winding of a transformer causing an alternating current voltage that is conductively isolated from the input signal to be developed across a secondary winding of the transformer. When the input signal is in the "power-off" state, it decouples the clock signal from the primary winding so that no alternating current voltage is developed across the secondary winding. The signal across the secondary winding is demodulated in a demodulator that produces a control signal that is conductively isolated from the input signal. The control signal is coupled to a regulator of the power supply. A power-on state of the control signal occurs when the alternating current voltage is developed at the secondary winding terminal. A power-off state of the control signal occurs when the alternating current voltage is absent.
摘要翻译：用于控制电视电源的输入信号具有“上电”和“断电”信号状态。当输入信号处于“上电”状态时，它将时钟信号耦合到变压器的初级绕组，导致与输入信号导电隔离的交流电压，以跨变压器的次级绕组开发。当输入信号处于“断电”状态时，它会将时钟信号与初级绕组分离，从而在次级绕组之间不产生交流电压。次级绕组中的信号在解调器中被解调，该解调器产生与输入信号导电隔离的控制信号。控制信号耦合到电源的调节器。当在次级绕组端子处产生交流电压时，发生控制信号的通电状态。当不存在交流电压时，发生控制信号的断电状态。

摘要： Images of underwater features, animate and inanimate, are produced from substantial distances in any direction around a boat, using small and easily mountable sonar devices, including three sonar transducers, two being stationary and the third being directable, the transducers being operable at various ultrasonic frequencies. Under keyboard control and using completely integrated electronic circuitry, images and echo sounding reports are generated on a graphic video display. The images include a sector-shaped image from a sector scan which covers a selected range of azimuth angles at a selected down angle.

摘要： This circuit provides a digital output indicating the presence or absence of the infrared (IR) carrier signal. The incoming IR signal is sampled by a clock at a frequency which is about 4 times the carrier frequency. The high and low samples are tabulated in two counters in a race. When 8 high or 16 low samples are counted, the envelope status flip flop is set or reset, respectively, and both counters are reset. The output of the envelope status flip flop represents the envelope of the IR carrier signal.

摘要： A control device signals user inputs to an audio-video display. The control device may be configured as a pillow speaker and include a speaker for reproducing audio from the audio-video display. The control device is coupled to the audio-video display by wiring. Shared signals in the wiring are used to provide power to operate the control device and are used to signal the user inputs to the audio-video display. A touch panel is used to sense user inputs. The touch panel may be transparent with an underlay containing indicia of user-selectable commands located below the touch panel. The arrangement and selection of commands available to the user may be modified by changing the underlay.

摘要： Apparatus for controlling various functions of a television receiver such as the picture and audio responses includes a keyboard with numbered keys which are normally used for selecting channels and a program key. When the program key is pressed, an on-screen character generator is caused to display a numbered list or menu of the various functions to be controlled. Thereafter, a particular function can be selected for control by pressing the correspondingly numbered key. This causes the numbered list or menu of the characteristics of the selected function, e.g., the brightness, contrast, sharpness, color level and color tint of the picture, to be displayed. Thereafter a particular characteristic can be selected for control by pressing the correspondingly numbered key.

摘要： In a system for communicating between multiple signal sources and at least one destination, communications occur via a communications, line shared by the signal sources. The multiple signal sources are coupled to the shared communications line via respective interface circuits. The interface circuits operate to determine which signal source will control the shared communications line. The operation of the interface circuits involves a switching or enabling function responsive to signal activity from one of the signal sources. The switching operation also involves assigning relative priorities to the signal sources. The priortizing feature results from an interaction between the relative impedances of the signal sources and the destination.

摘要： A television receiver includes a single tuner for tuning both television channels and broadcast FM stations. The tuner is operated at a fixed gain setting in FM reception mode. The tuner serves as the first conversion stage of a double conversion FM receiver, wherein the mixer of an FM radio integrated circuit serves as the second conversion stage. The arrangement operates at a specific and non-arbitrary first IF frequency. The FM receiver is also capable of automatically receiving National Weather Service broadcasts on that one of NWS's seven allocated frequencies which is operating in a listener's area. The receiver provides an on-screen display of the currently tuned FM channel number.
