Remotely controlled local interface lock -out system, with manual override, for electronic devices and appliances

This invention is an improvement to existing and future electronic remote control devices and the device that is controlled. This added improvement or feature allows for an electronic remote control system to disable the local control (i.g. pushbuttons, touchpads, etc.) of any or all of the functions of an electronic device while still allowing these functions to be controlled remotely. The electronic devices include but are not limited to televisions, video cassette recorders (VCRs), digital video disc (DVD) players, stereos, radios, appliances or entry systems. This disabling feature can be activated from, but not limited to, the remote control unit. This disabling feature can be deactivated either via the local interface (i.g. pushbuttons, touchpads, etc.) on the device that is under control or remotely via the remote control. If done locally, the deactivation can be triggered by, but not limited to, a sequence the user executes via existing pushbuttons or by other means on the local interface. Local interface deactivation is needed in cases where the remote control unit becomes unusable for any reason while the said disabling feature is active.

DETAILED DESCRIPTION OF THE INVENTION This section describes an improvement to existing and future electronic remote control devices and the device that is controlled. The functional block diagram of the design concept and implementation shown on the page titled “Drawing:” of this Utility Patent Application describes a system that remotely disables the local control of any or all of the functions of an electronic device while still allowing these functions to be controlled remotely. The electronic devices include but are not limited to televisions, video cassette recorders (VCRs), digital video disc (DVD) players, stereos, radios, appliances or entry systems. This disabling feature can be deactivated either locally or remotely. Blocks are denoted in boldface. Signals are denoted in Italics. The Local Control Interface is the physical means by which the user controls the functions of the electronic device. This is done via pushbuttons, keypads, touchpads, or any type of mechanical switch. The outputs of the Local Control Interface are the Local Control Signals that electronically control the functions of the device. The Remote Control Receive Unit is located inside the electronic device. It decodes the signal from a remote control device into signals that are useable by the Functional Control Unit and Blocking Control Unit.
