Measuring Temperature Change In An Electronic Biomedical Implant

US Patent:
7200504, Apr 3, 2007
Filed:
May 16, 2005
Appl. No.:
11/130644
Inventors:
Michael L. Fister - Simi Valley CA, US
Assignee:
Advanced Bionics Corporation - Valencia CA
International Classification:
G01R 23/00
G01K 7/00
US Classification:
702 75, 702130
Abstract:
The change in temperature of an implanted electronic device can be determined by providing power to one or more circuit elements included in the implanted electronic device, wherein the circuit elements comprise a non-crystal oscillator. A shift in the output frequency associated with the non-crystal oscillator can be detected, and the temperature change of the implanted electronic device can be determined based on the detected output frequency shift. One or more signals based on the output frequency associated with the non-crystal oscillator can be transmitted by the implanted electronic device. The transmitted signals can be received by an external device, which can detect the current output frequency associated with the non-crystal oscillator from the transmitted signals and compare the current output frequency with a previous output frequency to determine the output frequency shift associated with the non-crystal oscillator. The output frequency can, for example, be converted to a voltage measure.

Measuring Temperature Change In An Electronic Biomedical Implant

US Patent:
7426445, Sep 16, 2008
Filed:
Feb 16, 2007
Appl. No.:
11/676202
Inventors:
Michael L. Fister - Simi Valley CA, US
Assignee:
Boston Scientific Neuromodulation Corporation - Valencia CA
International Classification:
G01R 23/00
G01K 7/00

Systems And Methods For Communicating With Or Providing Power To An Implantable Stimulator

US Patent:
8386048, Feb 26, 2013
Filed:
Jan 11, 2005
Appl. No.:
11/034190
Inventors:
Kelly H. McClure - Simi Valley CA, US
Scott M. Loftin - Rosamond CA, US
Robert D. Ozawa - Woodland Hills CA, US
Michael L. Fister - Simi Valley CA, US
Assignee:
Boston Scientific Neuromodulation Corporation - Valencia CA
International Classification:
A61N 1/378
US Classification:
607 60, 607 61, 607 32, 607 31
Abstract:
An exemplary system for communicating with or providing power to an implantable stimulator includes a coil configured to emit a magnetic field for driving a corresponding circuit in the implantable stimulator and a coil driver circuit configured to drive the coil with a tuning frequency. The coil driver circuit actively adjusts the tuning frequency such that the coil operates at a frequency substantially equal to a resonant frequency. An exemplary method of communicating with or providing power to an implantable stimulator includes driving a coil with a tuning frequency and actively adjusting the tuning frequency such that the coil operates at a frequency substantially equal to a resonant frequency. The coil emits a magnetic field used to drive a corresponding circuit in the implantable stimulator.

Synthetic Aperture Video Photometer System

US Patent:
5267038, Nov 30, 1993
Filed:
Dec 30, 1988
Appl. No.:
7/292187
Inventors:
Michael L. Fister - Simi Valley CA
International Classification:
H04N 1700
US Classification:
358139
Abstract:
A synthetic aperture video photometer system wherein the synthetic aperture is established by an apparatus which senses video output from an interactively determined portion of an image-producing display, develops an electrical signal from the sensed video output and digitizes the electrical signal to develop an M by N array of digital pixel values, which correspond only to the interactively determined portion of the display. The apparatus then analyzes the pixel values for the automated inspection of the display. The automated inspection may include luminance, jitter and line width measurements. The synthetic aperture video photometer system provides a photo detector system which utilizes a synthetic aperture to eliminate the use of an aperture mask. The synthetic aperture video photometer system also provides a photo detector system wherein the synthetic aperture may be adjusted to eliminate undesirable video output of a test pattern which would saturate the photo detector.
