  • Publication number: 20200175301
    Abstract: Some dynamic pixel binning methods may involve identifying ROI optical sensor data corresponding to optical sensor pixels in a region of interest (ROI). Some such methods also may involve identifying non-ROI optical sensor data corresponding to optical sensor pixels outside the region of interest and determining a first binning factor for the non-ROI optical sensor data. The first binning factor may be based on a number of pixels in the region of interest and a target output data rate. Some such methods also may involve applying the first binning factor to the non-ROI optical sensor data and outputting optical sensor data, including the binned non-ROI optical sensor data, at the target output data rate.

  • Publication number: 20200137522
    Abstract: A user equipment (UE) has dual connectivity to a first Radio Access Technology (RAT) and a second RAT, such as Long Term Evolution (LTE) and New Radio (NR). The UE receives a request for location information for the first and second RATs, e.g., after transmitting capability information indicating dual connectivity. The UE obtains location information for the first and second RATs and transmits the location information to a location server. The location information, for example, may be location measurements obtained for the first and second RATs, a location estimate, or both. The request for location information may be received using the first RAT and the location information may be transmitted using the second RAT. The request for location information may include a first request for the first RAT, and a second request for the second RAT received after location information for the first RAT is obtained.

  • Patent number: 10616858
    Abstract: Disclosed are techniques for determining a location of a user equipment (UE) communicating over a shared communication medium in unlicensed spectrum. In an aspect, the UE receives a unique or distinct positioning reference signal (PRS) configuration for each of a plurality of secondary cells, where each PRS configuration includes a common set of positioning occasions and where the plurality of secondary cells are in contention for the common set of positioning occasions. The UE attempts to measure a PRS for each of the PRS configurations in each positioning occasion and typically measures a PRS for just one PRS configuration in each positioning occasion due to the contention for positioning occasions. The UE reports the PRS measurements and the identities of the measured PRS configurations to a location server which uses the reported data to determine a location for the UE.

  • Patent number: 10594921
    Abstract: Methods, systems, and devices for dual phase detection auto focus (PDAF) power optimization are described. A camera device may capture a frame including a pixel array representing a scene. In some examples, each pixel of the pixel array may be a phase detection (PD) pixel having one or more values, or one or more PD pixels positioned randomly across the pixel array. The camera device may identify a configuration of the pixel array, and determine a condition of the pixel array relative to the configuration. The configuration may be a binning configuration or a frame pattern configuration, and the condition may include an illumination condition related to the pixel array representing the scene. The camera device may determine and apply a reconfiguration to at least a portion of the pixel array based on the condition of the pixel array, and determine a lens position of the camera device therewith.

  • Publication number: 20200028583
    Abstract: Disclosed are techniques for determining a distance (or range) between a first wireless entity and a second wireless entity. In an aspect, the first wireless entity transmits a first positioning reference signaling (PRS) signal to the second wireless entity at a first time, where the first PRS signal is received by the second wireless entity at a second time, and receives a second PRS signal from the second wireless entity at a third time, where the second PRS signal is transmitted by the second wireless entity at a fourth time. The first wireless entity enables the distance to be determined by a location computing entity, for example, by a location server, based on the first, second, third, and fourth times. The first wireless entity may be a mobile device or a base station and the second wireless entity may be the other of the mobile device or base station.

  • Patent number: 10511771
    Abstract: Disclosed herein are techniques for dynamically configuring an image sensor of a mobile device for visible light communication (VLC) to an operational mode based on the position of the image of a VLC source on the image sensor and the different regions of interest (ROIs) of different operational modes of the image sensor. The operational mode that the image sensor is configured to has the smallest ROI among ROIs of operational modes that include at least a portion of the image of the VLC source on the image sensor. Techniques disclosed herein can reduce the power consumption of the mobile device during VLC communication and improve the effective sampling rate of VLC signals by the image sensor.

  • Patent number: 10291320
    Abstract: Techniques described herein, which may provide for a location determination of a mobile device, can also provide for the determination of a viewing direction of a user of the mobile device. In particular, a user can wear a head-mountable apparatus with one or more light sensors configured to detect light from one or more modulated light sources. Using this information, not only may a location of the head-mountable apparatus be determined, but also an orientation, which can enable a determination of an approximate direction the user is looking.
