An electrical connector for use, for example, at the end of an audio visual (A/V) system cable. The connector includes a body from which extends a sleeve for engaging a corresponding feature of another electrical connector. The sleeve of the electrical connector of the present invention forms a slot having a first portion and a second portion that intersect with each other, the first slot portion having an orientation that varies from the orientation of the second slot portion. In one embodiment, the connector includes a cylindrical sleeve, and the slot first portion extends from the distal end of the sleeve parallel to the connector's central axis and intersects the slot second portion at a right angle, meaning that in combination the first slot-portion and the second slot portion define a clip that extends along the periphery of the sleeve.

Electrical connector

A method and apparatus for high fidelity duplexing, local transmission and reception of audio-signals transmitted from sources such as stereos, televisions, or musical instruments is taught. According to these teachings, high fidelity wireless stereophonic transmission system having a plurality of audio channels are realized. An oscillator is electrically connected to the first audio channel to provide a first carrier frequency upon which the data of the first audio channel is imposed. The first carrier frequency is then combined with a second audio channel's data forming a composite signal. The composite signal is then imposed on signal generated by a second oscillator. This second oscillator provides a carrier frequency for a frequency modulated (FM) transmitter. The signal from the FM transmitter is received by a receiver and the respective signal's of the two audio channels are demodulated and used to drive speakers.

Method and apparatus for high fidelity wireless stereophonic transmission

An apparatus and method to use the temperature of a transmitting radio to prevent transmission of radio waves outside of an assigned frequency band. More specifically, if a transmitter exceeds a specified temperature the transmitter will be automatically disabled to prevent temperature caused frequency shifts outside the approved frequency transmission band for the transmitter. The transmitter has a temperature sensor that senses temperature and compare the operating temperature against a preselected temperature limit. It the operating temperature either is too hot or too cold the transmitter will be disabled and will not transmit until the temperature falls or rises to an acceptable level.
