Abstract: A bonding method and a bonding device for a flexible panel. In the process of bonding a protective cover plate and the flexible panel, a heated-type optical adhesive is used, the optical adhesive at normal temperature has relatively low viscosity and the viscosity thereof is below a bondable threshold, so that before the flexible panel and the edge of the protective cover plate are bonded, the optical adhesive and the edge of the protective cover plate come into contact in advance and then can be effectively separated, thus poor bonding in a bending region is avoided, the risk of generating bubbles and cracks is small, and the bonding yield can be improved. Moreover, the optical adhesive is increased in viscosity after heated, thereby ensuring that the flexible panel is bonded to the protective cover plate.

Abstract: An apparatus, e.g. a wireless media access point, includes a transceiver, a non-transitory storage medium, and a processor operably coupled to the transceiver and the storage medium. The processor is configured by instructions stored on the storage medium to transmit a first multicast channel associated with a first group temporal key (GTK), and to simultaneously transmit a second multicast channel associated with a second GTK.

Abstract: Charging systems and associated methods are disclosed that provide interim billing for a session in an IMS network. The charging system includes a charging data system that receives accounting messages from network elements serving the session in the IMS network, and generates partial CDRs for each network element based on the accounting messages. The charging data system also sets an aggregation/correlation timer. Responsive to an expiration of the aggregation/correlation timer, the charging data system aggregates the partial CDRs for each network element to generate an aggregated CDR for each network element. The charging system further includes a charging gateway system that, in further response to the expiration of the aggregation/correlation timer, correlates the aggregated CDRs to generate an interim consolidated CDR for the session, and transmits the interim consolidated CDR to a billing system. The billing system may then provide interim billing for the session based on the interim consolidated CDR.

Abstract: Apparatus and method for monitoring IP multicast delivery. One embodiment comprises an Optical Line Termination (OLT) device that includes a Network Termination (NT) device that connects to a core network, and a plurality of Line Termination (LT) devices that connect to an optical distribution network. The NT device generates an IP multicast monitoring stream directed to a group address, and transmits the monitoring stream to the LT devices. The LT devices then monitor for packets directed to the group address. When an LT device detects a loss of one or more packets directed to the group address, the LT device reports packet loss for the IP multicast monitoring stream to the NT device.

Abstract: Apparatus and methods for reporting stream loss in internet gateway devices. One embodiment comprises an internet gateway device for installation at a customer premises. The internet gateway device identifies a request to join an IP multicast stream identified by a group address, and monitors for packets directed to the group address. The internet gateway device detects a stream loss responsive to a failure to receive a packet directed to the group address during a time interval, and reports the stream loss for the group address to a management system.

Abstract: A content delivery system provides packet-level ratings of media content for use by client devices in rendering the media content thereon. A client device can store a permission level and compare the permission level with respective rating levels included in received media packets. The media content within the received media packets is rendered on the client device on the condition that the permission level compares favorably with the associated rating level and blocked on the condition that the permission level compares unfavorably with the associated rating level.

Abstract: Systems and methods that provide different levels of Internet Protocol Television (IPTV) services on Wi-Fi networks utilizing concurrent multicast streams. One embodiment comprises a Wi-Fi Access Point (AP) that identifies IPTV channel subscription information for users of Wi-Fi client devices. The AP utilizes multiple Group Temporal Keys (GTKs) to concurrently encrypt and multicast different IPTV channels, and provides the appropriate GTKs to the client devices based on the subscription information to allow different users of the Wi-Fi client devices to receive different packages of IPTV channels.

Abstract: Systems and methods are disclosed that monitor the speed that a mobile device is traveling, such as when the user of the mobile device is driving or riding in a vehicle. A speed monitoring system described herein receives a request from a third party to monitor a speed of a mobile device. The system periodically queries a mobile network for a location of the mobile device over a time period, and receives responses from the mobile network indicating locations of the mobile device. The system then determines a speed of the mobile device based on the locations indicated during the time period, and may determine the speed limit the roadway the mobile device is traveling on. The system then sends a notification message to the third party that includes an indication of the speed of the mobile device and possibly the speed limit.

Abstract: Systems and methods are disclosed that detect uninsured vehicles. An insurance monitoring system described herein receives a message over a mobile network from a mobile device embedded in a vehicle, where the message from the mobile device includes a vehicle identification for the vehicle. The insurance monitoring system queries an insurance database based on the vehicle identification to determine whether the vehicle is uninsured. If the vehicle is uninsured, then the insurance monitoring system sends a notification message to a law enforcement entity.
