Patent number: 8154389Abstract: A wireless sensor reader is provided to interface with a wireless sensor. The wireless sensor reader transmits an excitation pulse to cause the wireless sensor to generate a ring signal. The wireless sensor reader receives and amplifies the ring signal and sends the signal to a phase-locked loop. A voltage-controlled oscillator in the phase-locked loop locks onto the ring signal frequency and generates a count signal at a frequency related to the ring signal frequency. The voltage-controlled oscillator is placed into a hold mode where the control voltage is maintained constant to allow the count signal frequency to be determined.Type: GrantFiled: April 7, 2009Date of Patent: April 10, 2012Assignee: Endotronix, Inc.Inventors: Harry D. Rowland, Roger Dwight Watkins, Balamurugan Sundaram
