Patent number: 7937447Abstract: Methods and apparatus are provided for improving communication between processors in separate computer systems. Components and peripherals in individual computer systems communicate using input/output (I/O) buses such as PCI Express buses. The I/O buses are extended to allow interconnection between computer systems without having to introduce network infrastructure. A transfer controller supporting Direct Memory Access (DMA) is provided to allow even more efficient communication between computer systems.Type: GrantFiled: March 21, 2005Date of Patent: May 3, 2011Assignee: Xsigo SystemsInventors: Ariel Cohen, Shreyas Shah, Raymond Lim, Greg Lockwood

Patent number: 7937501Abstract: An improved method and apparatus is disclosed for communicating control information between components of an audio/video system. Processing and control logic is implemented to transfer a plurality of data streams on predetermined channels of a digital video interface. A first data stream contains video data received by a video interface receiver, where it is used to generate an image on a digital display. A second data stream contains control data, which is similarly received by the video interface receiver, and is used to control source devices coupled to the digital display.Type: GrantFiled: February 26, 2007Date of Patent: May 3, 2011Assignee: Dell Products L.P.Inventors: Joseph Edgar Goodart, David W.

Patent number: 7936776Abstract: This invention discloses a method for smooth capacity expansion of data communication product, and a smooth capacity expandable system of data communication. Architecture of the system at least comprises circuit card and switched network card; and further comprises interface card of switched network, interface transfer card and connection optical fiber. Based on these, it provides one kind of multiple frameworks structure with interconnection between frameworks. When the capacity is expanded, the original circuit cards and switched network cards keep unchanged, only smoothly increases the switched network cards and numbers of circuit card frameworks. Therefore, it implements smooth capacity expansion and client investment protection at the same time. With adding backup cards, it also implements capacity expansion without interrupting the service.Type: GrantFiled: December 8, 2006Date of Patent: May 3, 2011Assignee: Huawei Technologies Co., Ltd.Inventor: Chaojun Deng
