Appl. No.:

17/163098

Inventors:

- Redwood Shores CA, US
Robert James Hennessy - Pleasanton CA, US

Assignee:

Oracle International Corporation - Redwood Shores CA

International Classification:

G06F 40/18
H04L 29/06
G06F 9/445

Abstract:

A multidimensional data cube at a server may store values and functions. The functions may use values stored in the data cube as inputs to generate results. A client application may retrieve values stored at a server in a multidimensional data cube to be updated and viewed locally at the client. Instead of evaluating functions at the server and transmitting the results to the client, the functions themselves may be translated into equivalent functions that can be evaluated in real time at the client. As inputs to the functions are a changed at the client, the function results can be updated at the client without requiring back-and-forth transmissions to the server or additional queries to the data cube.

Robert Hennessy - San Jose CA, US
Joe Seeger - Menlo Park CA, US

International Classification:

G01C 19/5712
G01C 19/5783

Abstract:

The subject disclosure provides exemplary 3-axis (e.g., GX, GY, and GZ) linear and angular momentum balanced vibratory rate gyroscope architectures with fully-coupled sense modes. Embodiments can employ balanced drive and/or balanced sense components to reduce induced vibrations and/or part to part coupling. Embodiments can comprise two inner frame gyroscopes for GY sense mode and an outer frame or saddle gyroscope for GX sense mode and drive system coupling, drive shuttles coupled to the two inner frame gyroscopes or outer frame gyroscope, and four GZ proof masses coupled to the inner frame gyroscopes for GZ sense mode. Components can be removed from an exemplary overall architecture to fabricate a single axis or two axis gyroscope and/or can be configured such that a number of proof-masses can be reduced in half from an exemplary overall architecture to fabricate a half-gyroscope. Other embodiments can employ a stress isolation frame to reduce package induced stress.

International Classification:

G01C 19/5712
G01C 19/5747
G01C 19/5762

Abstract:

In a first aspect, the angular rate sensor comprises a substrate and a rotating structure anchored to the substrate. The angular rate sensor also includes a drive mass anchored to the substrate and an element coupling the drive mass and the rotating structure. The angular rate sensor further includes an actuator for driving the drive mass into oscillation along a first axis in plane to the substrate and for driving the rotating structure into rotational oscillation around a second axis normal to the substrate; a first transducer to sense the motion of the rotating structure in response to a Coriolis force in a sense mode; and a second transducer to sense the motion of the sensor during a drive mode. In a second aspect the angular rate sensor comprises a substrate and two shear masses which are parallel to the substrate and anchored to the substrate via flexible elements. In further embodiments, a dynamically balanced 3-axis gyroscope architecture is provided. Various embodiments described herein can facilitate providing linear and angular momentum balanced 3-axis gyroscope architectures for better offset stability, vibration rejection, and lower part-to-part coupling.
