  • Publication number: 20180176209
    Abstract: Concepts and technologies disclosed herein are directed to vehicle-to-everything (“V2X”) certificate management. According to one aspect of the concepts and technologies disclosed herein, a system can receive a CRL from a security credential management (“SCM”) system. The CRL can identify one or more certificates that have been determined to be invalid, such as when the certificate(s) has expired. The certificate(s) can be utilized by a vehicle for secure communications, including vehicle-to-vehicle (“V2V”) and vehicle-to-infrastructure (“V2I”) (collectively V2X). The system can format the CRL as a cell broadcast message. The system can then create a cell broadcast request directed to a cell broadcast center (“CBC”). The cell broadcast request can include the CRL formatted as the cell broadcast message. The system can send the cell broadcast request to the CBC to instruct the CBC to broadcast the CRL as the cell broadcast message.

  • Publication number: 20180159762
    Abstract: Switches within a telecommunications network exchange so-called available bandwidth messages, each of which advertises how much bandwidth remains unassigned on a respective link. The network is of a type in which circuits are provisioned with various predefined numbers of time slots (equivalent to bandwidth). The sending of an available bandwidth message for a given link is triggered by a change in the number of time slots available on that link if that change results in a change in the number of circuit bandwidths that can be accommodated by that link for a newly provisioned circuit.

  • Patent number: 9973964
    Abstract: A wireless data access system is provided to ameliorate bursty traffic occurring in a radio communications link such as a WiFi, WiMAX, 3G or cellular telephone link to a wireless network access device. A data traffic event is detected relating to traffic in the link. The traffic event may be a traffic burst exceeding a predetermined threshold. Based on detecting the data traffic event, a free-space optical communications link is established to the network access device to handle the traffic burst. The established radio link may be used to set-up and coordinate the free-space optical link.

  • Patent number: 9965476
    Abstract: A method of indexing multimedia content by creating database records that include location data is disclosed. Devices that generate multimedia content also generate location data corresponding to the location of the device when the content is generated. The location data includes geographical coordinates such as latitude and longitude as well as orientation and tilt. Other data may be recorded such as date and time of day, and light exposure. The content and location data are communicated to a Content Index Processor (CIP) that creates a database record from the location data and determines classifications for the database record that can be used by a person that is searching for particular multimedia content.

  • Publication number: 20180123640
    Abstract: Disclosed is a method and apparatus for reducing outbound interference in a broadband powerline communication system. Data is modulated on first and second carrier frequencies and is transmitted via respective first and second lines of the powerline system. A characteristic of at least one of the carrier signals (e.g., phase or amplitude) is adjusted in order to improve the electrical balance of the lines of the transmission system. This improvement in electrical balance reduces the radiated interference of the powerline system. Also disclosed is the use of a line balancing element on or more lines of the powerline system for altering the characteristics of at least one of the power lines in order to compensate for a known imbalance of the transmission system.

  • Patent number: 9942417
    Abstract: A method for providing local cordless service comprises the steps of receiving subscriber neighborhood zone selection input so that a mobile telephone equipped subscriber may place or receive calls for a fixed rate, for example, per month without having to pay radio frequency air time charges any time they are located within their selected subscribed-to zones. If the subscribed-to zones are adjacent to one another and the mobile subscriber roans from one zone to another, the subscriber may continue their fee call uninterrupted and without paying air time charges. However, when the subscriber roans outside their subscribed-to zones they may be switched from the present local cordless services to conventional personal communications services and pay air time charges. However for an active call, No air-time charges are incurred as the user transitions between the cellular/DPCS environment and the local cordless service environment.

  • Patent number: 9924201
    Abstract: A system and method of removing noise in a bitstream is disclosed. Based on the segment classifications of a bitstream, each segment or portion is encoded with a different encoder associated with the portion model and chosen from a plurality of encoders. The coded bitstream for each segment includes information regarding which encoder was used to encode that segment. A circuit for removing noise in video content includes a first filter connected to a first input switch and a first output switch, the first filter being in parallel with a first pass-through line, a second filter connected to a second input switch and a second output switch, the second filter connected in parallel with a second pass-through line, and a third filter connected to a third input switch in a third output switch.

  • Patent number: 9922430
    Abstract: Optimal resilience to errors in packetized streaming 3-D wireframe animation is achieved by partitioning the stream into layers and applying unequal error correction coding to each layer independently to maintain the same overall bitrate. The unequal error protection scheme for each of the layers combined with error concealment at the receiver achieves graceful degradation of streamed animation at higher packet loss rates than approaches that do not account for subjective parameters such as visual smoothness.

  • Patent number: 9913224
    Abstract: An adaptive SINR control process is triggered based on various quality measures associated with the received signal in a mobile device or on a geographic region in which a base station and an interferer are located. As part of the adaptive SINR control process, the mobile device reduces the signal level of the received signal, which reduces both the signal strength of the desired signal and the interfering signal. If the control process is triggered on the mobile device side, after detecting the presence of interference, the mobile device sends a request that the base station increase its transmit power of the desired signal to improve the receiving SINR in the mobile device. Alternatively, the mobile device may receive information from the base station causing the mobile device to reduce the signal level of the received signal based on quality indicators sent by the mobile device to the base station or based on geographic location of the base station.

  • Patent number: 9894325
    Abstract: A system and method to capture a plurality of images and store the captured images. The system has multiple camera systems capable of transmitting image data. At least one camera system is equipped with an apparatus for determining location coordinates such as GPS. A computer system monitors location coordinates, retrieves image data from the camera systems, and stores the image data into a file. A contiguous array of location coordinates is entered and the computer system locates camera systems within the contiguous array of location coordinates; retrieves image data from the located camera systems; and files the image data taken from each of the camera systems to obtain a file of image data. The system provides the ability to serially interleave frames or video captured from multiple sources.
