Abstract: A wireless telecommunication system is described that denies wireless telecommunication service to a wireless terminal in a proscribed area (e.g., prison, military installation, academic testing center, school, etc.). The system comprises an adjunct called a “service sentry.” The service sentry uses measurements of the location-dependent traits of the radio signals transmitted to, and received from, each wireless terminal in its purview to generate an estimate of the location of the wireless terminal. When the service sentry estimates that the wireless terminal has entered the proscribed area, it requests that the wireless switching center that services the proscribed area deny service to the wireless terminal. When the service sentry estimates that the wireless terminal has exited the proscribed area, it requests that the wireless switching center that services the proscribed area restore service to the wireless terminal.

Abstract: A method for performing contact tracing. An analysis system performing the method receives geo-temporal data comprising location data points for various wireless terminals, including the wireless terminals being used by people diagnosed as having a specified disease and the wireless terminals of others, one of whom having possibly infected those diagnosed with the disease. Based on filtering the geo-temporal data, the analysis system generates relatively-condensed mobility profiles that are representative of each person's locations and movements, and analyzes the mobility profiles. Through careful selections of various parameters based on the disease that is being analyzed, the mobility profiles are used instead of the relatively large amounts of geo-temporal data, to represent users of wireless terminals and to determine their interactions in regard to disease transmission.

Abstract: Techniques are provided for implementing a system for determining the range to a target object and orienting a map. In implementations, GPS data is used to determine the location of the system and an approximate distance from that location to the target. Based on the approximate distance, one or more parameters of operation of the system may be set. Modes of operation may be entered to further adjust parameters of operation. An optical pulse may then be projected at the target and its reflections collected and analyzed to calculate a distance measurement. A visual display may be adjusted based on the calculated distance estimate to the target.

Abstract: A method for performing contact tracing. An analysis system performing the method receives geo-temporal data comprising location data points for various wireless terminals, including the wireless terminal being used by a person diagnosed as having a specified disease and the wireless terminals of people who possibly have come in contact with the infected person. Based on filtering the geo-temporal data, the analysis system generates relatively-condensed mobility profiles that are representative of each person's locations and movements, and analyzes the mobility profiles. Through careful selections of various parameters based on the disease that is being analyzed, the mobility profiles are used instead of the relatively large amounts of geo-temporal data, to represent users of wireless terminals and to determine their interactions in regard to disease transmission.

Abstract: The present disclosure describes an apparatus for chemical-mechanical polishing of a semiconductor wafer. Some embodiments of the present disclosure include a pad, a slurry introduction mechanism, a wafer carrier (e.g., carrying a wafer being polished by the chemical-mechanical polishing system), a pad conditioner, and a pad cooling mechanism. The pad cooling mechanism of the present disclosure may apply a liquid or gas to the pad (e.g., to an upper surface of the pad) to control the temperature of the pad as the chemical-mechanical polishing process occurs. As a result, the temperature of the pad may be maintained at a safe and operable level for an extended period of time during chemical-mechanical polishing of a wafer.

A latch is attached to the long-handled object beneath the leg holder, and a slider is selectively movable along the lengths of the two legs and when moved towards the leg holder causes the legs to spread apart and spring outwardly away from the long-handled object, and when moved towards the latch, cause the legs to be brought together and extend parallel to and adjacent the long-handled object. The slider engages with the latch to lock the device in its propping position.

Abstract: Implementations relate to systems and methods for generating a user profile based on periodic location fixes. A cellular telephone or other mobile device captures location information via GPS or other capability. A location history can be generated from accumulated location fixes. The location history is then analyzed to detect the user's travel and dwell patterns. That information can be combined with business classification (e.g., SIC, etc.) or Point of Interest (POI) databases to identify a user's likely home, work, or other locations based on dwell-times, time of day, and other parameters. The user's age and gender can potentially be inferred based on types of locations visited, such as school locations. The user profile can be correlated with market segmentation databases to generate a marketing rating, such as a Nielsen or Claritas rating. Advertising, media, or other content can then be tailored to the user's individual location and demographic profiles.

Abstract: The thickness of subsurface layers if they had remained as they were prior to compaction may be estimated by restoring the volume of void space lost during compaction. Decompacted depths below seafloor, the depths the layers would be if compaction had not occurred, may be determined for the layers. A surrogate decompaction velocity may then be determined by dividing the decompacted depths by the travel times of acoustic waves that reflect off layers within the subsurface region. The decompaction velocity may be used in post-processing of acoustic data to produce a decompacted digital representation of the subsurface region. The decompacted digital representation may be used to directly interpret the thickness of layers prior to compaction, sedimentation rates over time, fault offsets, and other phenomena distorted by compaction.
