Patent number: 10478858Abstract: A piezoelectric micromechanical ultrasonic transducer (PMUT) includes a multilayer stack disposed on a substrate. The multilayer stack may include an anchor structure disposed over the substrate, a piezoelectric layer stack disposed over the anchor structure, and a mechanical layer disposed proximate to the piezoelectric layer stack. The piezoelectric layer stack may be disposed over a cavity.

Patent number: 10032008Abstract: A mobile device may perform authentication with an authenticating entity. The mobile device may comprise a plurality of sensors and a processor. The processor may be configured to: receive an authentication request from the authenticating entity requesting authentication information; and determine if the authentication request satisfies predefined user privacy preferences. If so, the processor may be configured to: retrieve the authentication information from at least one sensor to form a trust vector in response to the authentication request and to command transmission of the trust vector to the authenticating entity for authentication.Type: GrantFiled: October 24, 2014Date of Patent: July 24, 2018Assignee: QUALCOMM IncorporatedInventors: Jonathan Charles Griffiths, Eliza Yingzi Du, David William Burns, Muhammed Ibrahim Sezan

Patent number: 8736949Abstract: The color reflected by an interferometric modulator may vary as a function of the angle of view. A range of colors are thus viewable by rotating the interferometric modulator relative to an observer. By placing a textured layer between an observer and an interferometric modulator, a pattern which includes the range of colors may be viewed by the observer, and the range of colors may thus be viewable from a single viewing angle.Type: GrantFiled: December 20, 2011Date of Patent: May 27, 2014Assignee: QUALCOMM MEMS Technologies, Inc.Inventors: Manish Kothari, Gaurav Sethi, Jonathan Charles Griffiths, Eric Worthington
