Abstract: To permit the use of a single remote control device in an AV system that can supply incompatible video signals, a switch box (18) receives composite and S-video signals from an AV receiver, transforming these signals into the component video domain, and also receives component video signals from, e.g., a DVD player (14), with the output of the switch box being displayed on a television (16), and also receives a signal from a DVI source (101). The synchronization portion of the component video signal from the DVD player is sent to one of the input ports (14) of the AV receiver as a trigger signal for comparison thereof with the synchronization signal in the switch box (18). When a user selects the AV receiver input port into which the trigger signal is input, the sense signal at the switch box (18) is identical to the synchronization signal of the component video, and the switch box (18) consequently sends the component video to the television (16).

Abstract: An interchangeable electrical connector includes a connector body and an adapter body. The connector body includes electrical contact means, such as a banana plug tip, for engaging an electrical terminal. The connector body includes a conical portion and a threaded portion which is coaxial with the conical portion. The adapter body includes a conical portion which is shaped for co-operative engagement with the conical portion of the connector body, and a threaded portion which is coaxial to the conical portion of the adapter body. The threaded portion of the adapter body is for cooperative engagement with the threaded portion of the connector body, such that cooperative rotation of the connector body relative to the adapter body draws the conical portion of the connector body into engagement with the conical portion of the adapter body. The wedging action of the two conical portions frictionally engages the connector body to the adapter body.

Abstract: Method for the secure engagement of an electrical plug within its respective receptacle, for increasing the efficacy of the electrical contact therebetween, and apparatus to perform the method. An electrical plug, having reversibly expandable electrically conductive blades, includes an internal swage mechanism which enables the expansion of the blades within the receptacle once the blade has been inserted therein. The swage function is effective without recourse to additional tools.

Abstract: A circuit and method for improving the accuracy of an electrical signal communicated between electrical devices, particularly audio equipment, is disclosed herein. The apparatus includes a circuit that biases a cable to a biased voltage. A signal, analog or digital, is communicated through the biased cable. The present invention has applicability in any cable that is used to send electrical signals between electrical equipment, and particularly equipment for reproducing audio signals, such as high fidelity stereo equipment in order to more closely reproduce the musical qualities of the original recordings.
