Patent number: 8229699Abstract: Adaptive rule-based methods to solve localization problems for ad hoc wireless sensor networks are disclosed. A large problem may be solved as a sequence of very small subproblems, each of which is solved by semidefinite programming relaxation of a geometric optimization model. The subproblems may be generated according to a set of sensor/anchor selection rules and a priority list. The methods scale well and provide improved positioning accuracy. A dynamic version may be used for estimating moving sensors locations in a real-time environment. The method may use dynamic distance measurement updates among sensors, and utilizes subproblem solving for static sensor localization. Methods to deploy sensor localization algorithms in clustered distributed environments are also provided, permitting application to arbitrarily large networks. In addition, the methods may be used to solve sensor localizations in 2D or 3D space. A preprocessor may be used for localization of networks without absolute position information.Type: GrantFiled: May 16, 2011Date of Patent: July 24, 2012Assignee: The Board of Trustees of the Leland Stanford Jr. UniversityInventor: Holly Hui Jin

Patent number: 8074241Abstract: A method for providing panoramic videos and images to a user using a server-client architecture while minimizing the wait time necessary before still images are available for viewing or videos begin playing. A series of location-referenced panoramic images are separated into one-dimensional tracks. Intuitive user controls are provided which allow the user to start and stop video playback, step through the panoramas in a track one at a time, and change the viewing orientation within the panorama. A video will start playing as soon as the video files for the preferred projected cube faces have been downloaded. This delay is reduced by storing the videos as keyframe distance files for opposing directions for each cube face and further reduced by encoding videos with different starting points so that they are staggered by a portion of the keyframe distance.Type: GrantFiled: March 12, 2008Date of Patent: December 6, 2011Assignee: The Board of Trustees of the Leland Stanford Jr. UniversityInventors: Joakim Arfidsson, Hendrik Dahlkamp, Andrew Lookingbill, Sebastian Thrun

Publication number: 20110262839Abstract: A proton conducting electrolyte membrane comprising a ceramic electrolyte layer including an inorganic proton conductor and a ceramic protective layer formed on at least one surface of the ceramic electrolyte layer and having proton conductivity; a membrane electrode assembly including the proton conducting electrolyte membrane; and a proton conducting ceramic fuel cell including the membrane electrode assembly. In the proton conducting electrolyte membrane, the ceramic protective layer may have an improved chemical bond with the ceramic electrolyte layer compared with a Pd metal protective layer, such that interlayer delamination may be lessened. Also, compared with a Pd metal protective layer, the ceramic protective layer is more appropriate for ceramic electrolytes such as BYZ and BYC that transmit protons or simultaneously transmit protons and oxygen ions used in a fuel cell operating at a temperature range of about 200 to about 500° C., for example, about 250 to about 500° C.Type: ApplicationFiled: April 22, 2011Publication date: October 27, 2011Applicants: The Board of Trustees of The Leland Stanford JR.

Patent number: 7692425Abstract: The present invention provides a system and method for parallel imaging that performs auto-calibrating reconstructions with a 2D (for 2D imaging) or 3D kernel (for 3D imaging) that exploits the computational efficiencies available when operating in certain data “domains” or “spaces”. The reconstruction process of multi-coil data is separated into a “training phase” and an “application phase” in which reconstruction weights are applied to acquired data to synthesize (replace) missing data. The choice of data space, i.e., k-space, hybrid space, or image space, in which each step occurs is independently optimized to reduce total reconstruction time for a given imaging application. As such, the invention retains the image quality benefits of using a 2D k-space kernel without the computational burden of applying a 2D k-space convolution kernel.Type: GrantFiled: January 30, 2009Date of Patent: April 6, 2010Assignees: General Electric Company, The Board of Trustees of the Leland Stanford Jr. UniversityInventors: Anja C.
