Translational Mass In-Plane Mems Accelerometer
US Patent:
8307710, Nov 13, 2012
Filed:
Jul 9, 2009
Appl. No.:
12/500487
Inventors:
Paul W. Dwyer - Seattle WA, US
John Strehlow - Mukilteo WA, US
John Strehlow - Mukilteo WA, US
Assignee:
Honeywell International Inc. - Morristown NJ
International Classification:
G01P 3/00
US Classification:
7351439, 7351416
Abstract:
An in-plane Micro Electro-Mechanical Systems (MEMS) accelerometer device with improved performance. An example MEMS device includes one or more components for generating a magnetic flux field perpendicular to a major plane. The device also includes a substrate, a proof mass, a hinge element that flexibly connects the proof mass to the substrate, the major plane corresponds to a major surface of the proof mass, a plurality of conductive leads located at a position on the proof mass proximate the magnetic flux field, a plurality of conductive springs, each of the springs are electrically connected to a corresponding one of the conductive leads, and a plurality of anchor pads connected to the substrate and one of the conductive springs. Isolation trenches directly connect to outer edges of the leads that are adjacent to other leads or proof mass material. The leads and springs include a plurality of slots.

Honeywell International Inc. - Morristown NJ
International Classification:
G01P 15/125
US Classification:
7351432, 7351439, 7351417, 7351423
Abstract:
An in-plane, closed-loop Micro Electro-Mechanical Systems (MEMS) accelerometer device with improved performance. An example MEMS device includes one or more components for generating a magnetic flux field perpendicular to a major plane of the device. The device includes substrates, a proof mass, spring elements that flexibly connect the proof mass to the substrate and constrain the proof mass to translate within the major plane of the device which corresponds to a major surface of the proof mass, a plurality of conductive traces located at a position on the proof mass proximate the magnetic flux field, a plurality of conductive springs, each of the springs are electrically connected to a corresponding one of the conductive traces, and a plurality of anchor pads connected to the substrate and one of the conductive springs.
Mems Vibrating-Beam Accelerometer With Piezoelectric Drive
US Patent:
2012019, Aug 2, 2012
Filed:
Feb 2, 2011
Appl. No.:
13/019913
Inventors:
John Strehlow - Mukilteo WA, US
Doug MacGugan - Bellevue WA, US
Doug MacGugan - Bellevue WA, US
Assignee:
HONEYWELL INTERNATIONAL INC. - Morristown NJ
International Classification:
G01C 19/56
US Classification:
7350416
Abstract:
A high-temperature drive component for a double-ended tuning fork (DETF). The drive component attaches to a surface of at least one of the tines. The drive component includes at least one piezoelectric trace sandwiched at least partially between two electrical traces. At least one of the tines includes a doped silicon base with drive component located thereon. One of the electrical traces is electrically connected to the doped silicon base and the other is electrically isolated from the doped silicon base.
