  • Patient monitoring involving receiving multiple asynchronous data streams with antenna diversity
    Patent number: 9749900
    Abstract: A radio frequency (RF) receiving apparatus (10) includes a first and second omnidirectional RF antennas (20) at different spatial locations or orientations, a first and second RF receivers (24), each connected to a corresponding one of the first and second omnidirectional RF antennas (20), and a controller (32) connected to the first and second RF receivers (24). The first and second RF receivers (24) receive and demodulate RF signals of at least first and second carrier frequencies to recover data packets from at least a first device which transmits data packets on the first carrier frequency RF signal and a second device which transmits data packets on the second carrier frequency RF signal.
    Type: Grant
    Filed: July 28, 2014
    Date of Patent: August 29, 2017
    Assignee: KONINKLIJKE PHILIPS N.V.
    Inventors: Calvert Tazewell Hawkes, Robert Andrew Harwell

  • Tuned frequency portal for power transfer in MRI environment
    Patent number: 7382125
    Abstract: A circuit for isolating line voltage from a patient in an MRI environment, uses a filter network tuned to line voltage and incorporating blocking capacitors to eliminate the need for bulky air core transformers, complex energy transfer systems, and ferromagnetic components, while providing reduced heating such as might produce patient discomfort.
