Patent number: 10721594Abstract: Mobile devices provide a variety of techniques for presenting messages from sources to a user. However, when the message pertains to the presence of the user at a location, the available communications techniques may exhibit deficiencies, e.g., reliance on the memory of the source and/or user of the existence and content of a message between its initiation and the user's visit to the location, or reliance on the communication accessibility of the user, the device, and/or the source during the user's location visit. Presented herein are techniques for enabling a mobile device, at a first time, to receive a request to present an audio message during the presence of the user at a location; and, at a second time, detecting the presence of the user at the location, and presenting the audio message to the user, optionally without awaiting a request from the user to present the message.Type: GrantFiled: June 26, 2014Date of Patent: July 21, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Raja Bose, Hiroshi Horii, Jonathan Lester, Ruchita Bhargava, Kazuhito Koishida, Michelle L.

Publication number: 20070001186Abstract: An (Al, Ga, In)N and ZnO direct wafer bonded light emitting diode (LED), wherein light passes through electrically conductive ZnO. Flat and clean surfaces are prepared for both the (Al, Ga, In)N and ZnO wafers. A wafer bonding process is then performed between the (Al, Ga, In)N and ZnO wafers, wherein the (Al, Ga, In)N and ZnO wafers are joined together and then wafer bonded in a nitrogen ambient under uniaxial pressure at a set temperature for a set duration. After the wafer bonding process, ZnO is shaped for increasing light extraction from inside of LED.Type: ApplicationFiled: June 16, 2006Publication date: January 4, 2007Inventors: Akihiko Murai, Christina Chen, Daniel Thompson, Lee McCarthy, Steven DenBaars, Shoji Nakamura, Umesh Mishra

Publication number: 20060227099Abstract: A user input device includes one or more user controls that enable a user to selectively imports bits of data by activating the control when the user input devices proximate to a display surface of an interactive display system. By depressing or otherwise activating a user control, the user causes an element within the user input device to move through a plane of change so that the state of a parameter sensed by the interactive display system changes and is detected. In the examples provided, the parameter relates to infrared light that is reflected or absorbed or produced by a component of the user input device and is thus detected by an infrared sensitive camera. The input can be a single bit, or comprise a plurality of bits corresponding to a specific pattern.Type: ApplicationFiled: March 30, 2005Publication date: October 12, 2006Applicant: Microsoft CorporationInventors: Allen Ming-Kuang Han, Christina Chen, Dana Silverstein, Dawson Yee

Publication number: 20060092170Abstract: An object placed on an interactive display surface is detected and its position and orientation are determined in response to IR light that is reflected from an encoded marking on the object. Upon detecting the object on an interactive display surface, a software program produces a virtual entity or image visible through the object to perform a predefined function. For example, the object may appear to magnify text visible through the object, or to translate a word or phrase from one language to another, so that the translated word or phrase is visible through the object. When the object is moved, the virtual entity or image that is visible through the object may move with it, or can control the function being performed. A plurality of such objects can each display a portion of an image, and when correctly positioned, together will display the entire image, like a jigsaw puzzle.Type: ApplicationFiled: October 19, 2004Publication date: May 4, 2006Applicant: Microsoft CorporationInventors: Steven Bathiche, David Kurlander, Joel Dehlin, Dawson Yee, Donald Gillett, Christina Chen
