First Claim
Patent Images
1. A method, comprising:
- transmitting a first signal in a first format;
transmitting a second signal in a second format;
detecting, using an array, a wireless device within a given range generating a signal in response to the first signal,wherein the array comprises a staring antenna-coupled imaging array having lens elements, which comprise plastic, and dipole antennas coupled to diode detectors, wherein the array is configured to detect the signal generated by the wireless device to range resolution of about one meter for a range of up to about 100 meters; and
generating a detection signal upon detecting the device.
