Patent number: 9265428Abstract: A wireless sensor for indicating a physical state within an environment includes a housing defining a hermetically sealed cavity. A structure located within the cavity of the housing has elements providing capacitance, the elements being arranged such that the distance and thereby the capacitance of the structure changes when a physical state of the environment changes. The structure has a resonant frequency based at least in part on the capacitance of the structure when in the presence of a fluctuating electromagnetic field. When the sensor is positioned within an environment and is subjected to a fluctuating electromagnetic field, the resonant frequency indicates the physical state of the environment.Type: GrantFiled: July 18, 2008Date of Patent: February 23, 2016Assignee: ST. JUDE MEDICAL LUXEMBOURG HOLDINGS II S.A.R.L. (“SJM LUX II”)Inventors: David O'Brien, Jason White, Michael A. Fonseca, Jason Kroh, Mark Allen, David Stern

Patent number: 8237451Abstract: The present invention determines the resonant frequency of a 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 or set of frequencies and a predetermined amplitude. The energizing signal is coupled to the sensor via magnetic coupling and induces a current in the sensor which oscillates at the resonant frequency of the sensor. The system receives the ring down response of the sensor via magnetic coupling and determines the resonant frequency of the sensor, which is used to calculate the measured physical parameter. The system uses a pair of phase locked loops to adjust the phase and the frequency of the energizing signal.Type: GrantFiled: April 1, 2011Date of Patent: August 7, 2012Assignee: CardioMEMS, Inc.Inventors: James Joy, Jason Kroh, Michael Ellis, Mark Allen, Wilton Pyle
