Publication number: 20020172290Abstract: A method and apparatus for transporting signals from a high speed serial bus along a coaxial cable without using the physical layer (PHY). The wires from the high speed serial bus are used as analog inputs to a quadrature modulator. The quadrature modulator has a single radio frequency (RF) signal output that is connected to a coaxial cable for transmission along a distance of up to 100 meters. Furthermore, the RF signal is converted by a direct conversion tuner into signal outputs. The signal outputs are coupled to a second high speed serial bus connection. The high speed serial bus may be IEEE1394, Ethernet, or USB cable.Type: ApplicationFiled: May 18, 2001Publication date: November 21, 2002Inventors: Jack S. Chorpenning, John M. Dinwiddie

Patent number: 5434590Abstract: An information handling apparatus for transferring and composing image signals including a plurality of media sources configured to provide a corresponding plurality of image signals, a media bus connected to the media sources, and a media control module coupled to the media bus. The media bus allows selective access for the plurality of image signals. The selective access enables composition of the independent image signals in response to control information. The media control module receives a composed image signal from the media bus and provides the composed image signal to a display device.Type: GrantFiled: October 14, 1993Date of Patent: July 18, 1995Assignee: International Business Machines CorporationInventors: John M.

Patent number: 5388215Abstract: The functions of two virtual operating systems (e. S/370 VM, VSE or IX370 and S/88 OS) are merged into one physical system. Partner pairs of S/88 processors run the S/88 OS and handle the fault tolerant and single system image aspects of the system. One or more partner pairs of S/370 processors are coupled to corresponding S/88 processors directly and through the S/88 bus. Each S/370 processor is allocated from 1 to 16 megabytes of contiguous storage from the S/88 main storage. Each S/370 virtual operating system thinks its memory allocation starts at address 0, and it manages its memory through normal S/370 dynamic memory allocation and paging techniques. The S/370 is limit checked to prevent the S/370 from accessing S/88 memory space. The S/88 Operating System is the master over all system hardware and I/O devices.Type: GrantFiled: April 28, 1994Date of Patent: February 7, 1995Assignee: IBM CorporationInventors: Ernest D. Baker, John M. Dinwiddie, Jr., Lonnie E. Grice, James M. Joyce, John M. Loffredo, Kenneth R. Sanderson

Patent number: 4479179Abstract: A cycle steal mechanism for enabling a host processor to initiate and control the cycle stealing of data to or from a storage unit located in an I/O controller which is connected to the I/O channel bus of the host processor. The I/O controller also includes a microprocessor and a direct memory access (DMA) unit either or both of which can be used to control the transfer of data between the I/O controller storage unit and the host processor. Typically, the DMA unit is used for cycle stealing data between the controller storage unit and the host processor. The cycle steal mechanism of the present invention enables the host processor to also initiate and control the cycle stealing of data to or from the controller storage unit without interrupting the program running in the controller microprocessor and without interrupting the cycle stealing operations of the DMA unit.Type: GrantFiled: October 13, 1981Date of Patent: October 23, 1984Assignee: International Business Machines CorporationInventor: John M.
