Abstract: Disclosed are a reader device, system, and method for communicating with a wireless sensor. The reader device may be configured to analyze the strength of a response signal transmitted from the wireless sensor in response to an excitation pulse generated by the reader device. In one embodiment, the reader device may be configured to engage be placed in a plurality of modes to allow the reader to transmit a signal, such as a short pulse of energy or a short burst of radio frequency energy to cause the wireless sensor to output a resonant signal. The reader device may receive the resonant signal from the wireless sensor and evaluate it against predetermined values. The evaluated signals may be used to assess the strength and the proximity of the reader device relative to the wireless sensor as it is implanted in a patient.

Abstract: Disclosed is a self-test device and method for assessing the functional performance of a reader device that is configured to interface with a wireless sensor. The self-test device may be configured to analyze the accuracy of a signal transmitted from the reader device or the accuracy of a signal received by the reader device. In one embodiment, the reader device may be configured to engage the self-test device to allow the reader to transmit a signal, such as a short pulse of energy or a short burst of radio frequency energy to cause the self-test device to output a resonant signal. The self-test device may receive the transmit signal from the reader and evaluate it against predetermined values. The evaluated signals may be used to assess the accuracy of the transmit signal of the reader device to identify potential calibration issues and initiate remedial action by an automated system or human intervention if needed. The self-test device may be built into a docking station where the reader is placed when not in use.

Abstract: Disclosed is a reader device, system, and method for communicating with a wireless sensor. The reader device may be configured to communicate wirelessly with an implant device associated with a proprietary system provided by a first entity. An external device, that may not be associated with said first entity, is provided and is configured to be calibrated to communicate with the implant device that is located within a patient. The external device may be used in place of an existing reader device that was initially calibrated to communicate with the implant device prior to the implant device being placed within the patient. The external device may be particularly useful for implant devices that communicate wirelessly with external devices where said implant devices are intended to be located within the human body on a permanent or indefinite duration of time.

Abstract: A wireless circuit includes a housing having at least one opening, and sensor connected to the housing at the opening. The sensor includes a first layer having a first dimension and a second layer having a second dimension shorter than the first dimension. The second layer may be positioned entirely within the housing and a surface of said first layer may be exposed to an exterior of the housing.

Abstract: 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. The reader uses an ambient reading or other information to select a subset of the possible ring signal frequencies, and tunes or adjusts its circuits and algorithms to focus on that subset.
