  • Patent number: 10733736
    Abstract: This Invention is directed at the automated analysis of body scanner images. Body scanners are used in airports and other secured facilities to detect weapons, explosives, and other security threats hidden under persons' clothing. These devices use x-rays, millimeter waves and other radiant energy to produce an electronic image of the person's body and any concealed objects. Examination of these images by human analysts is slow, expensive, and subject to privacy concerns. The Invention provides automated analysis of body scanner images by recognizing that human anatomy is bilaterally symmetric to a high degree, while concealed objects are asymmetric. Digital techniques are used to separate the scanned image into its symmetric and asymmetric parts, thereby effectively separating anatomic from non-anatomic image features.

  • Patent number: 10339326
    Abstract: Methods, systems, and computer readable media can be operable to facilitate the encryption of a device identifier using an identification property of a SoC. A unique identifier of a cable modem may be encrypted using a unique key or other unique property of a SoC associated with the cable modem. When an authentication process is initiated at the cable modem, the encrypted unique identifier of the cable modem may be decrypted using the unique key or other unique property of the SoC, thereby producing the unique identifier of the cable modem. The decrypted unique identifier of the cable modem may be output from the cable modem to an upstream controller during the authentication process. In embodiments, an obfuscation key may be used to encrypt and decrypt the unique identifier of the cable modem, and the obfuscation key may be generated using a unique identifier of the SoC.

  • Patent number: 10306220
    Abstract: Embodiments disclose systems and methods for testing and determining outages of communication systems. A server can receive signal-reception-related information from set-top boxes (STBs) in a particular geographical region, where a STB: receives signals having a predefined pattern, generates a comparison of the predefined pattern to reference patterns stored on the STB, generates the signal-reception-related information based on the comparison, and sends the signal-reception-related information. The server can determine an outage status for the particular geographical region based on the signal-reception-related information. The server can generate an output based on the outage status. The output is configured to provide information related to the outage status of the particular geographical region and information for possible responses related to the outage status. The server can send the output.

  • Patent number: 10269141
    Abstract: Example embodiments relate to multistage camera calibration. An example embodiment includes a method. The method includes positioning a calibration target relative to a camera. The method also includes capturing a focused image of the calibration target. Further, the method includes determining one or more approximate locations of calibration points of the calibration target within the focused image of the calibration target. In addition, the method includes adjusting the focal length of the camera. Still further, the method includes capturing an unfocused image of the calibration target. Additionally, the method includes determining, based on the one or more approximate locations of calibration points of the calibration target within the focused image of the calibration target, one or more refined locations of calibration points of the calibration target within the unfocused image of the calibration target. Yet further, the method includes correcting for one or more optical aberrations within the camera.

  • Patent number: 10182248
    Abstract: In one embodiment, a video encoder generates an encoded bitstream representing a sequence of video frames including a keyframe. The encoder generates information for use by a decoder that receives the encoded bitstream to enable the decoder to generate display frames from a pre-keyframe video frame that is prior to the keyframe in the sequence of video frames. The encoded bitstream is sent to the decoder. In another embodiment, a video decoder receives from an encoder an encoded bitstream representing a sequence of video frames including a keyframe. The keyframe includes information to enable the decoder to generate display frames from a pre-keyframe video frame that was received prior to the keyframe in the sequence of video frames.
