Publication number: 20160352717Abstract: A system and method for controlling distribution and use of digital identity representations (“DIRs”) increases security, usability, and oversight of DIR use. A DIR stored on a first device may be obtained by a second device for use in satisfying the security policy of a relying party. Release of the DIR to the second device requires permission from a device or entity that may be different from the device or entity attempting to access the relying party. Further, the use of the DIR to obtain an identity token may separately require permission of even a different person or entity and may be conditioned upon receiving satisfactory information relating to the intended use of the DIR (e.g., the name of the relying party, type of operation being attempted, etc.). By controlling the distribution and use of DIRs, security of the principal's identity and supervisory control over a principal's activities are enhanced.Type: ApplicationFiled: August 10, 2016Publication date: December 1, 2016Applicant: Microsoft Technology Licensing, LLCInventors: John Shewchuk, Kim Cameron, Arun Nanda, Xiao Xie

Patent number: 9462179Abstract: A method of focusing an image sensor includes scanning a first portion of an image frame from an image sensor a first time at a first rate to produce first focus data. A second portion of the image frame from the image sensor is scanned at a second rate to read image data from the second portion. The first rate is greater than the second rate. The first portion of the image frame is scanned a second time at the first rate to produce second focus data. The first focus data and the second focus data are compared, and the focus of a lens is adjusted in response to the comparison of the first focus data and the second focus data.Type: GrantFiled: August 25, 2015Date of Patent: October 4, 2016Assignee: OmniVision Technologies, Inc.Inventors: Tiejun Dai, Eiichi Funatsu, Donghui Wu, Zheng Yang, Xiao Xie

Publication number: 20140215577Abstract: A system and method for controlling distribution and use of digital identity representations (“DIRs”) increases security, usability, and oversight of DIR use. A DIR stored on a first device may be obtained by a second device for use in satisfying the security policy of a relying party. Release of the DIR to the second device requires permission from a device or entity that may be different from the device or entity attempting to access the relying party. Further, the use of the DIR to obtain an identity token may separately require permission of even a different person or entity and may be conditioned upon receiving satisfactory information relating to the intended use of the DIR (e.g., the name of the relying party, type of operation being attempted, etc.). By controlling the distribution and use of DIRs, security of the principal's identity and supervisory control over a principal's activities are enhanced.Type: ApplicationFiled: February 10, 2014Publication date: July 31, 2014Applicant: Microsoft CorporationInventors: John Shewchuk, Kim Cameron, Arun Nanda, Xiao Xie

Patent number: 7802233Abstract: The intuitive display of trace historical data in a manner that processing control transfer between processing entities is represented in the context of trace data from multiple processing entities. For each processing entity, a set of one or more trace entries are identified for that processing entity and displayed in a manner that the trace entries for the processing entity are shown associated with the processing entity. The transfer of control between processing entities is also shown in a manner that illustrates a transfer of processing control.Type: GrantFiled: January 30, 2006Date of Patent: September 21, 2010Assignee: Microsoft CorporationInventors: Alexander T. Weinert, Lorenz S. Prem, Xiao Xie, Kan Zhang
