  • Publication number: 20100114225
    Abstract: Embodiments described herein provide lid structures for medical implant (MI) housing. In one embodiment, the invention provides a lid structure for a MI housing comprising a substrate comprising a dielectric material, a conductive portion fabricated on a substrate surface or interior, a frame at least partially surrounding the substrate perimeter, a plurality of vias projecting at least partially through the substrate, a plurality of conductive pins with at least one pin projecting through a via. The frame is hermetically joined to the substrate and can be hermetically joined to the housing. The conductive portion allows electrical components, including capacitors, inductors, resistor and antennas to be fabricated on or coupled to the substrate surface or interior. The antenna comprises a conductive trace positioned on a substrate top surface and is configured to send and receive signals between an implant within a patient's body and a communication device external to the body.

  • Patent number: 7623914
    Abstract: An implantable medical device (IMD) is provided. The IMD comprises a sense circuit, a main processing unit coupled to the sense circuit, a memory unit coupled to the main processing unit, and a reconfigurable processor unit coupled to the memory unit and the main processing unit. The reconfigurable processor unit is adapted to receive data, perform a processing function on the data, and return processed data to the memory unit. The memory unit is adapted to store the processed data. The main processing unit is adapted to execute programmed instructions and selectively reconfigure the processing function of the reconfigurable processor unit in response to one of the programmed instructions. Such a configuration can be used to implement a method of efficiently processing data in an IMD.

  • Patent number: 7054687
    Abstract: An apparatus for extracting activity information and position information from a composite signal generated by a motion sensor includes an analog to digital converter for converting the composite signal from analog to digital format. A wide-band low pass filter having a frequency response of about zero hertz to about ten hertz and a narrow low pass filter having a frequency response of about zero hertz to about 0.5 hertz filter the digitized composite signal. An adder subtracts the output of the narrow-band low pass filter from the output of the wide-band low pass filter. The resulting difference represents information regarding the activity level of the motion sensor, and the output of the narrow-band low pass filter represents information regarding the position of the sensor.

  • Patent number: 6356085
    Abstract: An apparatus for converting capacitance in a capacitive sensor into a voltage signal. A capacitive sensor monitors a physical parameter. A capacitance of the sensor varies with the physical parameter. A voltage supply applies an alternating voltage to the capacitive sensor, which creates an output signal from the sensor. A modulator modulates the output signal, which produces a voltage signal that corresponds to the capacitance of the sensor.
