Appl. No.:

09/326738

Inventors:

Michael A. Horton - Los Gatos CA
Jose A. Rios - Oakland CA
Jin Song - Saratoga CA

Assignee:

Crossbow Technology, Inc. - San Jose CA

International Classification:

G01P 2100

US Classification:

702 95, 702151, 702155, 701 11, 701220

Abstract:

A method and system senses the attitude of an accelerating object. Attitude sensing is accomplished by measuring acceleration in three orthogonal axes and measuring angular rate about each such axis to compute attitude accurately relative to a vertical axis. The system includes accelerometers and angular rate sensors for sensing the acceleration and the angular rate, respectively, of the object. A processor updates a quarternion representation of attitude based upon the angular rate of the object and a corrective rate signal to obtain the attitude of the object. Temperature compensation and frequency compensation may also be performed to update the quarternion.

Abstract:

Embodiments of the invention are directed to methods, systems and devices for providing sensitive user data to a mobile device using an encryption key. For example, a mobile application on a mobile device may receive encrypted sensitive user data from a mobile application server, where the user sensitive data is encrypted with a key from a token server computer. The mobile application may then request that the encrypted payment information be sent to the token server. The mobile device may then receive a payment token associated with the payment information from the token server.
