Digital Angular Rate And Acceleration Sensor

View page
US Patent:
6595054, Jul 22, 2003
Filed:
May 14, 2001
Appl. No.:
09/855213
Inventors:
Jerome M. Paros - Kirkland WA
Theo P. Schaad - Seattle WA
Assignee:
Paroscientific, Inc. - Redmond WA
International Classification:
G01P 904
US Classification:
7350404, 7351429
Abstract:
A digital angular rate and acceleration sensor is constructed with force-sensitive resonators positioned longitudinally on one or both sides of the neutral bending plane of a cantilevered structure. The cantilevered structure has an inertial proof mass at its free end with a periodic velocity applied sideways to the bending plane. Rotation about the longitudinal axis, which produces periodic Coriolis acceleration, as well as inertial acceleration applied perpendicular to the bending plane, generate tensile and compressive forces on the resonators thereby altering the resonant frequencies that are thus a measure of angular rate of rotation and acceleration.

Triaxial Acceleration Sensor

View page
US Patent:
6826960, Dec 7, 2004
Filed:
Aug 7, 2002
Appl. No.:
10/214920
Inventors:
Theo P. Schaad - Seattle WA
Jerome M. Paros - Kirkland WA
Assignee:
Quartz Sensors, Inc. - Redmond WA
International Classification:
G01P 1510
US Classification:
7351429, 73510
Abstract:
A triaxial acceleration sensor comprises an inertial mass suspended in three orthogonal directions by support members in a statically determinate structure. Acceleration applied to the inertial mass generates loading forces that stress the support members either in tension or in compression. The stress levels are thus a measure of the applied acceleration. In an embodiment of this invention, the support members are force-sensitive resonators whose resonant frequencies of oscillation are related to the stresses in the members. The resonant frequencies are thus a measure of the complete three-dimensional vector of the applied acceleration.

High-Resolution Digital Seismic And Gravity Sensor And Method

View page
US Patent:
8616054, Dec 31, 2013
Filed:
Aug 6, 2008
Appl. No.:
12/187229
Inventors:
Jerome M. Paros - Kirkland WA, US
Theo P. Schaad - Seattle WA, US
Assignee:
Quartz Seismic Sensors, Inc. - Redmond WA
International Classification:
G01V 7/02
US Classification:
73382G
Abstract:
A high-resolution digital seismic and gravity sensor includes an inertial mass connected to one or more force-sensitive resonators. The weight of the inertial mass is substantially unloaded with a spring arrangement when exposed to the force of the static gravity field. Seismic accelerations applied to the base of the seismic and gravity sensor, or changes in the gravitational field, generate loads that are transmitted to force-sensitive resonators so that changes in resonant frequency are related to the applied load. The changes in resonant frequency are thus a measure of the seismic accelerations and gravitational field variations.

Method For Eliminating Output Discontinuities In Digital Pressure Transducers And Digital Pressure Transducer Employing Same

View page
US Patent:
20020117006, Aug 29, 2002
Filed:
Feb 23, 2001
Appl. No.:
09/792324
Inventors:
Jerome Paros - Kirkland WA, US
Theo Schaad - Seattle WA, US
International Classification:
G01L009/00
US Classification:
073/717000
Abstract:
Digital pressure transducers employing force-sensitive resonators are designed according to a method that eliminates spurious mode resonances. The dimensional and geometrical relationships of the force-producing pressure elements and structures are chosen such that spurious modes of oscillation are not excited by the resonant modes of the force-sensitive resonators.
