  • Patent number: 9398072
    Abstract: In a KVM system, a system provides for USB devices to be accessed by target computers. A KVM switch connects a client with a target server via a network, the client computer having at least one device attached thereto. A second mechanism connects to a USB port of the target and communicates with the target using a USB protocol. A client mechanism communicates with the second mechanism via the network. A virtual media mechanism enables the target server to access the USB device attached to the client.

  • Publication number: 20110191810
    Abstract: Methods and systems provide for the distribution of both computer and home entertainment information. Computer and home entertainment audio-visual sources are distributed to displays throughout a house, and any of the sources can be viewed from any of the displays. Computers and televisions are integrated while allowing the computers and the televisions to be located in separate rooms of the house, thereby minimizing the need to co-locate items or to install additional wiring. The computer and home entertainment sources may be located in a single area and distributed to various receivers throughout the house. Multiple users may share any given information source. The entertainment and computer sources are connected to a single information hub that distributes the various source signals to remote receivers. Users may view any of the sources from any receiver in the house, and multiple different users may view different sources from any receivers in the house.

  • Publication number: 20110129784
    Abstract: The present disclosure relates to a silica-based crucible material that includes, before sintering or firing, selected amounts of a thermal expansion stabilizer component (B2O3 and Ca2SiO4) which impart improved thermal shock resistance and enhanced ability to withstand repeated thermal cycling, to a sintered or fired crucible made of the material. An illustrative embodiment of the invention provides a crucible material whose chemical composition comprises, in weight %, about 91% to about 98% SiO2, about 1% to about 8% thermal stabilizer component, and up to about 1.0% of additional oxides including MgO, Al2O3 Fe2O3, CaO and ZrO2.

  • Publication number: 20110109801
    Abstract: Methods and systems are provided to switch television channels during a commercial break and automatically notify the viewer when the commercial on the original channel is over so that the user may switch back to watch the original channel. This permits a viewer to avoid commercials during live television while maximizing the viewing of desired content on the original channel. A television channel selection device includes two independent tuners. In normal operation, a first tuner provides channel-selected signals to a television. When a viewer sees a commercial, the system begins a process employing a second independent tuner to internally monitor the first tuner signal until the termination of the commercial is detected. In the meantime, the first tuner provides channel-selected signals so that the viewer may view other channels. The viewer is notified of the end of the commercials by one of a variety of notification techniques.

  • Patent number: 7555567
    Abstract: A keyboard/video/mouse (KVM) switching protocol is disclosed in which KVM information is applied to a network of workstations. At least one data converter communicates on the workstation network and retrieves KVM information from the workstation network that is addressed to a server assigned to the converter. The converter places the KVM information in a format suitable to the assigned server and applies the converted KVM information to the appropriate standard device ports of the server. The system provides motherboard access to the servers that is characteristics of KVM switches but provides essentially unlimited scalability not known in traditional KVM switches.

  • Patent number: 7424551
    Abstract: A passive video multiplexing method and apparatus for encoding video synchronization signals within a KVM extension system. A Rack Interface Pod (RIP) is provided for receiving video signals from a network server and providing them to a remote user via a local area network (LAN). The analog signals received by the RIP are transmitted to a Rack Connection Manager (RCM) having video processing logic, a supervisory processor, a KVM switch system, and Ethernet interface circuitry. A plurality of ARI systems are connected to the RCM, and a plurality of network servers, intended to be controlled by the remote user, are connected to each ARI by a respective wiring strip or Pod Expansion Module (PEM). The RCM performs selective switching by sourcing current through a pair of diodes associated with an active channel of the PEM while reverse biasing diodes associated with an inactive channel to select a network server among the plurality of network servers.

  • Patent number: 6748473
    Abstract: A split computer (122) comprises a main module (140) remotely connected by external PCI bus (170) to a input/output (I/O) or extension module (142). The main module (140) comprises a processor (181) and an external PCI bus first interface (300). The input/output (I/O) module comprises one or more input and/or output device controllers and an external PCI bus second interface. The external PCI bus connects the external bus first interface of the main module with the external bus second interface of the input/output (I/O) module. The main module executes application programs, maintains user configurations, and maintains application configurations. Yet since the main module is located remotely, e.g., at a data center (150), the both security and centralized management are realized using existing hardware and software. The input/output (I/O) module has a relative small footprint and primarily performs input and output operations.
