Patent number: 9671499Abstract: The effective use of weak GPS signals that are present in various environments enables an electronic device to pinpoint its location in such environments. The electronic device uses an antenna to perform sequential scanning in multiple directions for global positioning system (GPS) signals. The electronic device further analyzes GPS signals obtained from scanning the multiple directions to determine a number of acquired GPS satellites that provided the GPS signals. The GPS signals include code phases of the acquired GPS satellites. The electronic device then computes a location of the electronic device based on the code phases of the acquired GPS satellites when the number of acquired GPS satellites meets a threshold.Type: GrantFiled: October 30, 2013Date of Patent: June 6, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Jie Liu, Gerald R. DeJean, Nissanka B. Priyantha, Yuzhe Jin, Edward Hart, S M Shahriar Nirjon

Patent number: 9331743Abstract: Biological entity communication channel techniques are described. In one or more implementations, an apparatus includes a signal conductor having a side that is configured to be disposed proximal to a surface of a biological entity to use at least a part of the biological entity as a transmission channel to transmit a signal received by the signal conductor from an electrical device. The apparatus also includes a ground layer configured to be disposed on an opposing side of the signal conductor from the side of the signal conductor that is configured to be disposed against the surface of the biological entity.Type: GrantFiled: December 8, 2011Date of Patent: May 3, 2016Assignee: Microsoft Technology Licensing, LLCInventors: Ran Gilad-Bachrach, Gerald R. DeJean, Trang Thuy Thai

Patent number: 8708241Abstract: Radio frequency certificates of authenticity (RFCOAs) and associated scanners and methods are presented. In one implementation, an array of miniaturized antenna elements in an RFCOA scanner occupies an area smaller than a credit card yet obtains a unique electromagnetic fingerprint from an RFCOA associated with an item, such as the credit card. The antenna elements are miniaturized by a combination of both folding and meandering the antenna patch components. The electromagnetic fingerprint of an exemplary RFCOA embeddable in a credit card or other item is computationally infeasible to fake, and the RFCOA cannot be physically copied or counterfeited based only on possession of the electromagnetic fingerprint.Type: GrantFiled: December 8, 2009Date of Patent: April 29, 2014Assignee: Microsoft CorporationInventors: Gerald R DeJean, Darko Kirovski

Patent number: 8410985Abstract: Mobile device antennas with dielectric loading are described herein. In one example, a mobile device includes a ground plane, carried within an enclosure. An antenna is connected to the ground plane. Dielectric loading material is provided within at least a portion of an area defined between the ground plane and the antenna. The dielectric loading material results in a shortening of a required antenna length, thereby creating a recovered area, i.e., valuable space within the enclosure “recovered” by the use of dielectric loading material.Type: GrantFiled: June 7, 2010Date of Patent: April 2, 2013Assignee: Microsoft CorporationInventors: Sean R. Mercer, Gerald R. DeJean

Patent number: 8384608Abstract: Technology is described for a slot antenna. The slot antenna can include a substrate having a metal layer on a first side of the substrate. A feed line can be located on a second side of the substrate. A first polygon shaped slot can be formed in the metal layer of a first side of the substrate. A second polygon shaped slot can also be formed in the metal layer of the first side of the substrate. The second polygon shaped slot can be recessed within a perimeter of the first polygon shaped slot and the second polygon shaped slot and first polygon shaped slot share a common side. Examples of the first and second polygon shapes may include square or diamond shapes.Type: GrantFiled: May 28, 2010Date of Patent: February 26, 2013Assignee: Microsoft CorporationInventor: Gerald R.

Patent number: 8188925Abstract: A bent monopole antenna with shared segments is capable of tri-band communication. In an example embodiment, an antenna assembly includes a substrate, a first bent monopole, a second bent monopole, and a third bent monopole. The first, second, and third bent monopoles are disposed on the substrate. The first bent monopole includes a feedline segment and a first segment. The second bent monopole includes the feedline segment and the first segment. The third bent monopole includes the feedline segment and a second segment. The first, second, and third bent monopoles share the feedline segment, while the first and second bent monopoles also share the first segment. A T-junction is formed by the feedline segment, the first segment, and the second segment. In an example implementation, the first segment has a first width, and the second segment has a second width, with the first width being greater than the second width.Type: GrantFiled: November 7, 2008Date of Patent: May 29, 2012Assignee: Microsoft CorporationInventor: Gerald R.
