Abstract
A radio frequency controller device enables the utility of a target to be controlled using an RF communication. The radio frequency controller device has a switch that is set to a defined state responsive to the RF communication. More particularly, conditional logic circuitry uses the RF communication to determine if the target'"'"'s utility should be changed, and sets the state of the switch accordingly. The radio frequency controller device also has a target interface that allows the target to determine the state of the switch, and based on the state of the switch, a different utility will be available for the target. The radio frequency controller device also has an antenna for the RF communication, as well as a demodulator/modulator circuit. When used to control the utility of an electrical or electronic device, the radio frequency controller device has a low-power circuit portion that is used to set the state of the switch responsive to the RF communication, and also has a full power circuit portion that communicates with the target. In this way, the state of the switch may be set when the target is in a power-off condition, and the target is able to determine the state of the switch when the target is activated.
