  • Patent number: 6456488
    Abstract: A portable notebook computer having a thickness of only one inch is obtained by provision of a computer housing containing a keyboard assembly and a motherboard positioned directly below the keyboard assembly, the keyboard assembly and the motherboard thereby defining a region in the enclosure. The other components comprising the computer; i.e. a hard disk drive, a PCMCIA option slot, a trackball assembly, and a DC to DC convertor, are positioned in an adjacent and generally co-planar relationship with this region. A battery housing is mounted externally on the computer housing for supplying electrical power to the computer.

  • Publication number: 20020133828
    Abstract: Web pages with integrated video are rendered in a head-end without the video content. The head-end creates key frames that depict the graphical representation of web pages, again exclusive of program video. Key frames arriving at set top boxes are written to a background display plane and signal that program video redirected by head-end to set top box should be rendered to an overlay display plane.

  • Patent number: 6378068
    Abstract: A laptop computer system includes a protected mode microprocessor capable of operating in restricted and unrestricted modes, and an arrangement which in response to a predetermined condition saves information from the processor and then forcibly switches the processor to its unrestricted mode of operation. When running a multi-tasking operating system where an application program is being executed in a restricted mode, a suspend/resume operation can be carried out in which the system is substantially powered down and then powered back up, and will resume the interrupted application with the restricted mode back in effect. Further, set-up changes such as adjustment of the processor speed can be made without exiting the application program running in the restricted mode.

  • Publication number: 20020040391
    Abstract: A network architecture is provided in which a server farm is assembled with systems-on-a-chip, each of which implements one or more integrated standard or other network interfaces. The standard network interface of a system-on-a-chip is connected point-to-point to the standard network interface on another system-on-a-chip. The configuration disclosed herein eliminates the need for standard network opponents when assembling the server farm, resulting in significant savings both in terms of cost and space.

  • Patent number: 5974261
    Abstract: A computer system has a processing unit with suspend/resume capability, a memory, and a hard disk drive. In response to a first command from the processor, the hard disk drive sends its status to the processor and the processor stores it in the memory. In response to a second command from the processor, the hard disk accepts from the processor the status retrieved by the processor from the memory, and restores itself to this status. In an alternative embodiment, the hard disk drive response to the first command by storing its status on its own hard disk, and responds to the second command by restoring this status from the hard disk. In each case, an output line from the hard disk used to control a light emitting diode is also selectively used to create an interrupt to the processor which facilitates the systems entry into the suspend mode.

  • Patent number: 5901035
    Abstract: A very thin portable computer includes a computer housing for holding electronic components and a battery housing movably mounted external to the computer housing, the battery housing adapted for holding batteries for supplying power to the electronic components. The battery housing is rotatably mounted on the computer housing such that the battery housing rotates between a closed position wherein the battery housing covers the rear side of the computer and an open position wherein the battery housing exposes connectors on the computer housing and elevates the rear side of the computer housing to an angle convenient for typing.

  • Patent number: 5638532
    Abstract: Computer systems using a processor that is capable of operating in a system management mode (SMM) employ a dedicated system management RAM (SMRAM). The processor uses the SMRAM when the processor is performing a task associated with the SMM. The processor is capable of generating a range of system addresses. The range includes a particular subrange of system addresses that are used for accessing the SMRAM. A memory controller decodes the system addresses generated by the processor and enables access to the SMRAM, regardless of whether the processor is operating in the SMM, when the controller decodes a system address of the particular subrange. The range of system addresses also includes a second subrange. The memory controller also enables access to the SMRAM when the processor is operating in the SMM and the controller decodes a system address of the second subrange. The memory controller indicates to the processor whether data associated with the enabled SMRAM can be stored in a cache memory.
