  • Patent number: 11938326
    Abstract: Implantable medical systems enter an exposure mode of operation, either manually via a down linked programming instruction or by automatic detection by the implantable system of exposure to a magnetic disturbance. A controller then determines the appropriate exposure mode by considering various pieces of information including the device type including whether the device has defibrillation capability, pre-exposure mode of therapy including which chambers have been paced, and pre-exposure cardiac activity that is either intrinsic or paced rates. Additional considerations may include determining whether a sensed rate during the exposure mode is physiologic or artificially produced by the magnetic disturbance. When the sensed rate is physiologic, then the controller uses the sensed rate to trigger pacing and otherwise uses asynchronous pacing at a fixed rate.

  • Patent number: 7796157
    Abstract: A system and method for diagnosis of video device performance in the transfer of audio visual data over a video network physically interfaces with the network to receive audio visual data associated with the video device of interest and uses diagnostic tools to access the audio visual data for determination of performance statistics with analysis of the accessed audio visual data, including video device jitter, latency, throughput, and packet loss.

  • Patent number: 7061871
    Abstract: A system and method for identifying errors in a video conference conducted on a network are disclosed. A central device includes a central agent that detects an error during a video conference conducted on a network between two or more endpoints. The central agent distributes a capture agent via the network to a remote device associated with a collision domain that contains one of the two or more endpoints. The capture agent collects a plurality of media packets associated with the video conference in a capture file located in a storage medium associated with the remote device until a timer expires. When the timer expires, the capture agent communicates the capture file to the central agent at the central device.

  • Patent number: 6590603
    Abstract: The present invention discloses a system for managing streaming data. The system includes a management module and a processing module. The processing module includes a CODEC and a streaming appliance. The CODEC connects to a MCU, receives video conference data, and decompresses video conference data. The streaming appliance functions to receive video conference data, format video conference data for streaming, and send streaming video conference data to a selected network address. The management module functions to selectively manage the CODEC and the streaming appliance and their communication with associated systems. More particularly, the streaming appliance may be a web server that functions to transmit video conference data to a selected internet address.

  • Publication number: 20030028535
    Abstract: The present disclosure describes a system and method for a call control system for managing a video network. The call control system includes a master gatekeeper that is able to associate with and manage multiple video network elements, including circuit switched video network elements and packet switched video network elements. The call control system also includes a call control database and a connection engine. The call control database stores registration and status information related to associated network elements. The connection engine analyzes conference call requests and determines the appropriate connection required for the associated network element.
