  • Patent number: 10896449
    Abstract: A facility procuring information about a distinguished property from a user knowledgeable about the distinguished property that is usable to refine an automatic valuation of the distinguished property is described. The facility displays information about the distinguished property used in the automatic valuation of the distinguished property. The facility obtains user input from of the user adjusting at least one aspect of information about the distinguished property used in the automatic valuation of the distinguished property.

  • Patent number: 10575199
    Abstract: A method is provided for performing over-the-air (OTA) testing of a device under test (DUT). The method includes establishing an OTA connection with the DUT, while the DUT is in signaling mode, the OTA connection including advertising channels and data channels; sending universally unique identifier (UUID) requests at different transmit powers to the DUT over the data channels of the OTA connection; receiving UUID responses from the DUT over the data channels of the OTA connection in response to at least some of the UIDD requests; and determining a packet error rate (PER) for the received UUID responses from the DUT based on a ratio of a number of received responses and a number of sent connect requests. The determined PER indicates sensitivity of a receiver in the DUT.

  • Patent number: 9195116
    Abstract: Systems and methods for focus control in a pan-tilt-zoom (PTZ) camera system are described herein. An example of a method described herein includes identifying a set of trace curves associated with the camera system, each of the trace curves specifying relationships between focus lens positions and zoom lens positions for a corresponding camera position, selecting a trace curve using the set of trace curves and one or more of pan angle, tilt angle or installation height of the camera system, and identifying a focus lens position for a current zooming factor of the camera system based on the selected trace curve.
