    摘要： An absolute capacitive micro pressure sensor including a pressure sensor element (250) with a mechanically fixed electrode and a deflectable pressure sensor membrane separated from the fixed electrode by a predetermined distance. A packaging defining a chamber is formed by a cover (207) assembled to a base plate (206) with an opening defined therein. The chamber is filed with a fluid and/or a gas at substantially constant pressure. Within the chamber, the pressure sensor element is mounted to the base plate to define an open cavity therebetween substantially aligned with the opening defined in the base plate. A gel (205) is disposed in the open cavity in contact with an exposed surface of the deflectable membrane.

    摘要： Optimal power switching circuitry for use in a closed system such as a TET system including an internal device (105) separated from an external device (100) by a boundary. The internal (105) and external (100) devices being powered by separate power sources. During telemetric communication from the external device (100) to the internal device (105) an external RF energy source is produced. If the power supplied by the external RF energy source produced during communication from the external device (100) to the internal device (105) exceeds that required for powering of the internal device (105), then the power switching circuitry cuts off power to the internal power source and instead draws power from the external RF energy source thereby conserving power consumed from the internal power source (130). The power switching circuitry may be implemented using either passive components (e.g., diodes) or active components (e.g., an analog switch).

    摘要： An implantable active pressure transducer including a pressure sensing element and associated sensor circuitry together enclosed within an innermost glass packaging. The pressure sensing element is anodically bonded to the innermost packaging substantially aligned with an opening defined therein. An outermost biocompatible metal packaging forms a cavity divided into first and second chambers by an intermediate partition. The innermost packaging is disposed within the first chamber without physically directly contacting or being fixed to the outermost packaging. A barrier plate is hermetically sealed to the intermediate partition to hermetically isolate the battery and communication circuitry from a pressure transmitting fluid. Inductive coupling is used to communicate data detected by the pressure sensing element internally within the implant.

    摘要： An implant includes a processor, RF communication circuitry, optical communication circuitry, a power source and a memory, all of which being hermetically sealed within a housing having a transparent window. Sensor readings are transmitted by RF using the RF communication circuitry to a remote reader after receiving interrogation signals from the reader. During calibration of the sensor, corrective coefficients are calculated by comparing actual sensor pressure readings with known pressure readings. The corrective coefficients are transmitted to the memory of the control circuitry using optical communication wherein modulated light is transmitted through the transparent window of the housing to the photo-detector.
