  • Method of improving sensitivity and interference rejection in wireless receivers
    Patent number: 8711979
    Abstract: A wireless receiver for receiving a signal with a characteristic pattern includes a predictor for predicting the presence of a non-zero value of the characteristic pattern. A tracker tracks a noise component in the received signal between predicted non-zero values. The resulting noise component is subtracted from the received signal to output a processed signal, which is then decoded by a pattern discriminator and demodulator. The wireless receiver is less sensitive to noise and interference.

  • Implantable RF telemetry devices with power saving mode
    Patent number: 8538544
    Abstract: An electronic implantable device with a power saving circuit incorporates a radio frequency receiver with high power consumption. The first power radio receiver of high power is normally turned off during a period of inactivity. When an analyzer forming part of a second radio receiver and coupled to the first radio receiver detects a predetermined identification code in a received radio frequency signal received by the second radio receiver, it outputs a signal to turn on the first power receiver.
