Method And Apparatus For Driving A Radiation Source

View page
US Patent:
20070278384, Dec 6, 2007
Filed:
May 31, 2007
Appl. No.:
11/756574
Inventors:
Kevin Heppell - Oakland CA, US
Assignee:
OPTISCAN BIOMEDICAL CORPORATION - Hayward CA
International Classification:
G01J 1/32
US Classification:
250205
Abstract:
A method and apparatus are described for driving a modulated radiation source (which can be, for example, an infrared light source). The method affects the power driving a light source in such as way so as to minimize the warm-up time of the source. The apparatus permits feedback control of a light source to specified powers or temperatures. Disclosed embodiments can improve source performance and lifetime and decrease the operating costs of the source.

Noise Reduction For Analyte Detection Systems

View page
US Patent:
20070258083, Nov 8, 2007
Filed:
Apr 11, 2007
Appl. No.:
11/734261
Inventors:
Kevin Heppell - Oakland CA, US
James Braig - Piedmont CA, US
Assignee:
OPTISCAN BIOMEDICAL CORPORATION - Hayward CA
International Classification:
G01N 33/48
US Classification:
356039000
Abstract:
Methods and apparatus are provided for determining the concentration of an analyte in a sample, such as an analyte in a sample of bodily fluid. Some embodiments use a synchronous demodulator and digital filter to reduce microphonic signal content. Some embodiments monitor the microphonic signal content and “hold off” on making a measurement until vibrations subside. Monitoring can be performed using an accelerometer or other vibration sensor. An algorithm can be used to examine the detector output signal and detect excessive microphonic components, making an accelerometer unnecessary.

Methods For Physical Authentication Of Medical Devices During Wireless Pairing

View page
US Patent:
20190222564, Jul 18, 2019
Filed:
Dec 21, 2018
Appl. No.:
16/229807
Inventors:
- St. Paul MN, US
Kevin Heppell - Portland OR, US
International Classification:
H04L 29/06
G16H 40/40
H04W 12/06
H04W 12/04
A61M 1/12
Abstract:
Systems and methods for physical authentication of medical devices during wireless pairing are disclosed herein. The method can include receiving a request to initiate coupling. Following the request, a visual identifier can be generated with a light source. The visual identifier can include embedded data used to couple the medical devices. The visual identifier can be captured in image data, which image data can be analyzed and the embedded data can be extracted from the image data. Based on the embedded data that is extracted from the image data, secure coupling between medical devices can be established.

Integrated Implantable Tets Housing Including Fins And Coil Loops

View page
US Patent:
20170250575, Aug 31, 2017
Filed:
May 12, 2017
Appl. No.:
15/593855
Inventors:
- Pleasanton CA, US
George Chao-chih Hsu - San Ramon CA, US
John Duc Nguyen - San Ramon CA, US
Carine Hoarau - Lafayette CA, US
Steven Reichenbach - Pleasanton CA, US
Kevin Gerald Heppell - Oakland CA, US
International Classification:
H02J 50/12
H02J 7/02
H01F 38/14
Abstract:
Systems and methods for wireless energy transfer are described. A transmitter unit has a transmitter resonator with a coil that is coupled to a power supply to wirelessly transmit power to a receiver unit. A receiver unit has a receiver resonator with a coil coupled to a device load. The receiver unit can include a ferrite enclosure to prevent transmission of magnetic flux into electronics of the receiver unit, and can include ferrite fins to increase a coupling between the transmitter resonator and the receiver resonator.
