Abstract: Dynamic data clock rate for data transfer to a display. The rate at which data is transferred from memory by a processor to a display is controlled such that data is transferred at or near one or more pixel refresh rates specified for the display while allowing at least one of the processor or memory to perform other tasks. A rate at which data is transferred from the processor to the display is reduced when the processor and/or memory is burdened with other tasks. When the processor and/or memory become more available as a result of reduction or elimination of other tasks, the rate at which data is transferred from the processor to the display is increased.

Abstract: A system ling client computers, particularly client notebook computers, to communicate with a computer local area network (LAN) using infrared or other transparent links. The system includes a pseudo nic driver, transparent communication hardware, and a transparent link in a network interface unit. The pseudo nic driver hides the technical details of the transparent communications by presenting itself as a traditional nic driver to the client networking software. The network interface unit bi-directionally communicates via the transparent link with an, for example, an infrared enabled client computer and performs the necessary bridging between the low level infrared signals and traditional LAN system such as Ethernet.
