Device and method for selectively controlling a processing device
First Claim
1. An RF controlled target, comprising:
- a radio frequency controller device, further comprising;
a switch configured to selectively activate data processing logic, the data processing logic having a data input line and a processed data output line;
a demodulator/modulator connected to the switch;
an antenna connected to the demodulator/modulator; and
wherein the switch activates the data processing logic responsive to receiving an RF signal; and
a processor operating the steps comprising;
sending data to the data input line;
generating expected data using the sent data;
receiving modified data from the data output line;
comparing the modified data to the expected data; and
operating the processor responsive to the comparison.

Abstract
A switch device is provided that selectively enables the utility of a processing device. In one example, the processing device is a microprocessor operating in a target device, such as a computer system, and the switch device is a radio frequency controller device that sets the switch responsive to an RF signal. The processing device only operates when: 1) the processing device is installed in the expected target device; and 2) the switch has been activated, for example, using the RF signal. The radio frequency controller device has a switch that is set to a defined state responsive to the RF signal. Conditional logic circuitry may use the RF signal to determine if the switch should be activated, and sets the state of the switch accordingly. The radio frequency controller device operates a data processing process only when the switch is activated. A processing device sends data to the radio frequency controller device, and if the switch is active, the processing device receives modified data in response. The processing device also generates expected data, and compares the expected data to the modified data. If the expected data matches the modified data, then the processing device is allowed to operate.
