摘要： A television receiver cable of tuning either "air" channels in an "air" tuning mode or "cable" channels in a "cable" tuning mode includes apparatus for automatically selecting the tuning mode. The auto-tuning mode apparatus operates in conjunction with apparatus for automatically programming a memory for storing tuning information for tunable channels. When the auto-programming mode is selected, the receiver is caused to operate in the cable tuning mode and a search is conducted for active cable channels. If a predetermined number of active cable channels is located, the receiver remains in the cable tuning mode and the memory is programmed with tuning information for all of the cable channels. If the predetermined number of cable channels is not located, the receiver is caused to operate in the air tuning mode and the memory is programmed with tuning information for all of the air channels.

摘要： A system and method of tuning an antenna of a portable device in a modular device system using a device ID associated with second device to tune one or more antennas of a first device. In an embodiment, the first device resolves the device ID of the second device to a set of tuning parameters which improve tuning of the antenna of the first device in the presence of the second device. In a further embodiment, the first device may also tune an antenna of the second device to improve its performance in the presence of the first device.

摘要： Receiver (1-9) provided with a frequency control loop (2-6) for automatic fine tuning, consecutively incorporating a controllable oscillator (6) which is tunable in frequency by means of a variable capacitance diode (D), a mixer stage (2) to which the signal from the controllable oscillator (6) is applied for converting an RF receiver signal into an intermediate frequency signal, a frequency voltage converter (4) tuned to a fixed intermediate frequency for converting frequency deviations of the intermediate frequency signal relative to the fixed intermediate frequency into amplitude variations of the frequency voltage converter (4) output signal relative to a refrence value, a control signal generating circuit (5) for deriving a control signal for the variable capacitance diode (D) of the controllable oscillator (6) from the output signal of the frequency voltage converter (4), which at least partly compensates the asymmetrical diode capacitance-voltage characteristic. In order to prevent unwanted side-tuning effects from occuring during this compensation, the frequency-dependent variation of the control signal for the variable capacitance diode (D) is to assume an asymmetrical S curve which is curved around the maximum values therein and which compensates the asymmetry in the diode capacitance variation.

An oscillation frequency controlling element which forms an external oscillation frequency control section of the digital oscillator and a circuit constant variable upon variations in its working length, is mounted on an operator operable knob shaft on the operational panel of the radio receiver around the rotation path of a sweep speed controlling element mounted coaxially thereto. The sweep speed controlling element and the oscillation frequency controlling element are connected to an input section of the digital oscillator. There is further provided a Distance/LOCAL receiver mode selecting element coaxially on the knob shaft.

摘要： A wireless single-frequency-channel, full-duplex, full-time transmit and receive communication node includes an antenna that transmits a transmit signal over a wireless transmit channel and that receives a receive signal over a wireless receive channel. A communications processor includes a first port electrically coupled to the antenna and a second port electrically coupled to a transmit path where the transmit path connects the second port to the first port. A third port of communications processor is electrically coupled to a receive path that connects the first port to the third port. The communications processor is configured to pass the transmit signal in the transmit path to the first port and configured to pass the receive signal in the receive path from the first port to the third port such that the transmit signal and the receive signal occupy a same frequency channel and operate simultaneously in a same time slot.
