摘要： Aspects of the present invention determine the resonant frequency of a sensor by obtain sensor signals in response to three energizing signals, measure the phase of each sensor signal, and using a group phase delay to determine the resonant frequency. The phase difference between the first and second signal is determined as a first group phase delay. The phase difference between the second and third signal is determined as a second group phase delay. The first group phase delay and second group phase delay are compared. Based on the comparison, the system may lock on the resonant frequency of the sensor or adjust a subsequent set of three energizing signals.

摘要： A communication system for communicating with an implanted wireless sensor is provided. A transmit antenna element can propagate an energizing signal onto a communication medium and a receive antenna element can recover a responsive implanted sensor response signal. The antenna box (204) includes a power amplifier for amplifying the energizing signal and timing regeneration circuitry for detecting an end to signals and outputting control signals for selecting mode operation. The antenna box can receive the energizing signal from the antenna cable (208) in a transmit mode and provide the implanted sensor response signal to the antenna cable in a receive mode. The antenna box can communicate with an electronic box (210) and/or conversion box (206) that provide and receive signals and provide power via the antenna cable.

摘要： Aspects and embodiments of the present invention provide a loosely-coupled oscillator including a sensor circuit and an electronic device that are not physically connected. In some embodiments, the electronic device includes an amplifier stage and a feedback network and the sensor circuit includes one or more LC circuits.

摘要： The present invention determines the resonant frequency of a wireless sensor by adjusting the phase and frequency of an energizing signal until the frequency of the energizing signal matches the resonant frequency of the sensor. The system energizes the sensor with a low duty cycle, gated burst of RF energy having a predetermined frequency. The system receives the ring down response of the sensor and determines the resonant frequency of the sensor, which is used to calculate a physical parameter. The system uses a pair of phase locked loops to adjust the phase and the frequency of the energizing signal. The system identifies false locks by detecting an unwanted beat frequency in the coupled signal, as well as determining whether the coupled signal exhibits pulsatile characteristics that correspond to blood pressure.

摘要： Attenuation in a received signal caused during transmission of the signal to a receiver is automatically compensated. An amplitude of first reference data within the received signal is compared (220) with an amplitude of second reference data. A gain of the received signal is varied (200) based on the results of the comparison. The amplitude comparison and gain varying are repeated until the amplitude of the first reference data and the amplitude of the second reference data differ by a predetermined amount.
