Indexing Dithering Mechanism And Method

View page
US Patent:
7505140, Mar 17, 2009
Filed:
Apr 13, 2007
Appl. No.:
11/735014
Inventors:
Igor Leonidovich Tchertkov - Concord CA, US
Randall Jaffe - Clayton CA, US
Assignee:
Custom Sensors & Technologies, Inc. - Moorpark CA
International Classification:
G01C 19/70
US Classification:
356476, 7350401
Abstract:
Dithering mechanism and method for eliminating the effects of zero-rate bias in a rate sensor or gyroscope. Both continuously moving and indexing embodiments are disclosed. The mechanism includes a first part mounted in a fixed position centered about a dither axis perpendicular to the input axis of the gyroscope, a second part disposed coaxially of the first part and affixed to the sensing element of the gyroscope, and a plurality of piezoelectrically driven quartz flexure beams extending radially between the first and second parts for dithering the second part about the dither axis. In some embodiments, the dithering mechanism is formed separately from and affixed to the sensing element of the gyroscope, and in others it is formed integrally with the sensing element. In the indexing embodiments, radial arms and fixed stops limit movement of the mechanism between two fixed positions, and drive signals and holding potentials are applied alternately to dither the mechanism between the two positions and to hold it alternately in those positions during successive data acquisition periods.

View page
US Patent:
8506506, Aug 13, 2013
Filed:
Dec 30, 2009
Appl. No.:
12/649781
Inventors:
Dragan D. Nebrigic - Carlsbad CA, US
Herb Lara - Newark CA, US
Richard Hatch - Pleasanton CA, US
Igor Leonidovich Tchertkov - Walnut Creek CA, US
Kai Nakamura - San Mateo CA, US
Laura England - Alameda CA, US
Marlo Cinco - Castro Valley CA, US
Assignee:
Solta Medical, Inc. - Hayward CA
International Classification:
A61H 1/00
A61H 1/02
A61H 5/00
US Classification:
601 15, 607100
Abstract:
Apparatus and methods for delivering electromagnetic energy to a patient's tissue with a reduction in the pain experienced by the patient. The tissue treatment apparatus includes a delivery device configured to transfer electromagnetic energy through the skin surface to a region of tissue and a vibration device mechanically coupled with the delivery device. The vibration device is configured to transfer mechanical vibrations through the skin surface to the region of tissue.

Anchor-Tilt Cancelling Accelerometer

View page
US Patent:
20120125104, May 24, 2012
Filed:
Sep 30, 2011
Appl. No.:
13/249902
Inventors:
Jin Qiu - Sunnyvale CA, US
Joe Seeger - Menlo Park CA, US
Alexander Castro - San Francisco CA, US
Igor Tchertkov - Pleasanton CA, US
Richard Li - Mountain View CA, US
Assignee:
InvenSense, Inc. - Sunnyvale CA
International Classification:
G01P 15/125
G01P 15/00
US Classification:
7351432, 7351416
Abstract:
Described herein is an accelerometer that can be sensitive to acceleration, but not anchor motion due to sources other than acceleration. The accelerometer can employ a set of electrodes and/or transducers that can register motion of the proof mass and support structure and employ and output-cancelling mechanism so that the accelerometer can distinguish between acceleration and anchor motion due to sources other than acceleration. For example, the effects of anchor motion can be cancelled from an output signal of the accelerometer so that the accelerometer exhibits sensitivity to only acceleration.

Abstract:
A Microelectromechanical systems (MEMS) structure comprises a MEMS wafer. A MEMS wafer includes a handle wafer with cavities bonded to a device wafer through a dielectric layer disposed between the handle and device wafers. The MEMS wafer also includes a moveable portion of the device wafer suspended over a cavity in the handle wafer. Four methods are described to create two or more enclosures having multiple gas pressure or compositions on a single substrate including, each enclosure containing a moveable portion. The methods include: A. Forming a secondary sealed enclosure, B. Creating multiple ambient enclosures during wafer bonding, C. Creating and breaching an internal gas reservoir, and D. Forming and subsequently sealing a controlled leak/breach into the enclosure.
