Publication number: 20180277938Abstract: A flexible antenna is associated with an active implantable medical device to facilitate communication between the implantable medical device and an external component in the outside world via, for example, long range or far field telemetry. The flexibility of the antenna allows it to conform to the shape of the location at which it is situated, such as on the cranial bone of a patient for an antenna associated with a cranially implanted medical device. The conformability of the antenna helps to maintain the antenna in the desired shape and to maintain it in the desired location relative to implantable medical device and the patient and improves patient comfort.Type: ApplicationFiled: May 31, 2018Publication date: September 27, 2018Inventors: Dean ANDERSEN, Stephen T. ARCHER, John Dunagan PEARSON

Publication number: 20160303572Abstract: A system and method for liberating different materials in recyclable material streams is provided. A material stream is introduced into an adjustable dwell time shredder. The dwell time of the shredder is adjustable by rotating the shredder from a first position to a second position, thereby changing the migration rate of objects within the shredder. The liberation of materials is not dependent on the ability of the shredder to reduce materials to a certain granule size in order to pass through a grate or screen. The dwell time of the shredder may be adjusted during operation of the shredder.Type: ApplicationFiled: April 15, 2016Publication date: October 20, 2016Inventors: Randall R. Brace, Dean Andersen

Patent number: 8386049Abstract: A communication wake-up scheme for an implantable medical device may involve repeatedly activating a receiver to determine whether an external device is attempting to establish communication with the implantable device. To reduce the amount of power consumed by the implantable device in conjunction with the wake-up scheme, the scheme may involve conducting preliminary RF signal detections as a precursor to conducting a full scan. In this way, power may be conserved since the more power intensive full scans may be performed less frequently. This preliminary detection of RF signals also may be adapted to reduce the number of full scans performed by the implantable device that do not result in communication with the external device. In some embodiments the adaptation involves adjusting one or more thresholds that are used in conjunction with the preliminary detection of RF signals.Type: GrantFiled: April 27, 2011Date of Patent: February 26, 2013Assignee: Pacesetter, Inc.Inventors: Benjamin T. Persson, Dorin Panescu, Dean Andersen

To reduce the amount of power consumed by the implantable device in conjunction with the wake-up scheme, the scheme may involve conducting preliminary radio frequency signal detections as a precursor to conducting a full scan. In this way, power may be conserved since the more power intensive full scans may be performed less frequently. This preliminary detection of radio frequency signals also may be adapted to reduce the number of full scans performed by the implantable device that do not result in communication with the external device.

Publication number: 20100114225Abstract: 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.Type: ApplicationFiled: November 5, 2008Publication date: May 6, 2010Inventors: Mir Imran, Dean Andersen, Joel Harris

Patent number: 7054687Abstract: 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.Type: GrantFiled: August 29, 2002Date of Patent: May 30, 2006Assignee: Pacesetter, Inc.Inventors: Dean Andersen, Marc Ryat

Patent number: 6356085Abstract: 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.Type: GrantFiled: May 9, 2000Date of Patent: March 12, 2002Assignee: Pacesetter, Inc.Inventors: Marc Ryat, Dean Andersen
