  • Publication number: 20240107113
    Abstract: Various implementations disclosed herein include devices, systems, and methods that provide video content (e.g., a TV show, a recorded sporting event, a movie, a 3D video, etc.) within a 3D environment using parameters selected based on one or more contextual factors. Such contextual factors may be determined based on an attribute of the content (e.g., its intended purpose or viewing environment), the user (e.g., the user's visual quality, interpupillary distance, etc.), the 3D environment (e.g., current lighting conditions, spatial considerations, etc.), or other context attributes.

  • Patent number: 8618625
    Abstract: A planar, waveguide-based silicon Schottky barrier photodetector includes a third terminal in the form of a field plate to improve the responsivity of the detector. Preferably, a silicide used for the detection region is formed during a processing step where other silicide contact regions are being formed. The field plate is preferably formed as part of the first or second layer of CMOS metallization and is controlled by an applied voltage to modify the electric field in the vicinity of the detector's silicide layer. By modifying the electric field, the responsivity of the device is “tuned” so as to adjust the momentum of “hot” carriers (electrons or holes, depending on the conductivity of the silicon) with respect to the Schottky barrier of the device.

  • Patent number: 7640288
    Abstract: A method, schema and computer system for a location service provides data structures that are extensible by allowing different types of location awareness applications to retrieve and deposit location data. The method includes providing an abstract location object arranged in a schema to enable servicing a received request for a logical location of an electronic endpoint; and arranging one or more location elements within the context of the abstract location object. The location elements are configured to act as peers relative to the logical location and each location element is configured to act as a proxy relative to any other location element within the abstract location object.

  • Publication number: 20030115228
    Abstract: A schema-based location service for Internet access to per-user location data, wherein access to data is based on each user's identity. The location service includes a schema that defines rules and a structure for each user's data, and also includes methods that provide access to the data in a defined way. The location schema thus corresponds to a logical document containing the data for each user. The user manipulates (e.g., reads or writes) data in the logical document by data access requests through defined methods. In one implementation, the location schemas are arranged as XML documents, and the services provide methods that control access to the data based on the requesting user's identification, defined role and scope for that role. In this way, data can be accessed by its owner, and shared to an extent determined by the owner.
