First Claim
Patent Images
1. A receiver comprising:
- a sensor for receiving a signal;
a band-pass filter in communication with the sensor; and
a processor in communication with the band-pass filter, wherein the processor is configured to transmit a confirmation signal to the band-pass filter if the signal is distinguishable from noise.
