  • Publication number: 20160103339
    Abstract: A dual-sensory eyewear device for providing visual and aural distractions. The dual-sensory eyewear device includes a frame to which a pair of voltage controlled liquid crystal display lenses and audio devices may be connected. An electronics system and a power system are also included and are housed within the frame. The power system provides electrical current while the electronics package dictates operation of the lenses and the audio devices. Display drivers of the electronics package allow the pair of lenses to switch between an opaque and transparent state, while an audio amplifier operates the pair of speakers. Operation commands to dictate use of the pair of lenses and the pair of speakers can be remotely transmitted to the electronics package through a wireless communication module and interpreted through a signal decoder.

  • Patent number: 8873374
    Abstract: A method is disclosed that enables an improved technique for recovering from an error scenario encountered during a call setup involving a malfunctioning media gateway and corresponding media gateway controller. The media gateway first detects a malfunction that affects a digital signal processing resource, and then proactively selects a processing resource available elsewhere at the gateway. The media gateway selects the new processing resource based on criteria including: i) the capabilities that were identified to handle the packet stream at the affected (faulty) processor; ii) the capabilities of the IP terminal originating the packet stream that is being moved; and iii) the Internet Protocol address of the affected processing resource. Advantageously, an effort is made to avoid having to inform the media gateway controller of the move, thereby minimizing any discontinuity in each packet stream and minimizing the time and processing that are required to establish the call.
