Abstract
A method and apparatus for allowing or disrupting passage of power in electrical appliances includes a portable wireless remote control device and a device in the form of an electronic circuit contained within one particular electrical appliance that is adapted for allowing or disrupting passage of power in the electrical appliance based upon wireless signals received from the wireless remote control device. The electrical appliance may be any of a variety of electrical appliance, such as a television, a video cassette recorder, a computer, a washer, a dryer, and the like. The wireless remote control device includes a housing. The housing includes mounted therein a display, thirteen input keys each representing two letters of the alphabet, and ten input keys respectively representing the numbers zero through nine. The housing also includes a DELETE input key, an ENTER input key, a left cursor input key, a right cursor input key, a down cursor input key, and an up cursor input key. The housing also includes a power cord which leads to a connector adapted for electrically connecting to an AC or DC power source external of the remote control device. An electrical appliance configured in accordance with the invention is equipped with a device in the form of an electronic circuit including an antenna, a wireless transceiver, a discriminator, an analog to digital and digital to analog converter, a digital logic controller, a memory, and a relay.
