Latest Patents
One of Ramsay's latest patents is the Multi-plane page mode video memory controller. This invention describes a page mode memory controller designed for multi-plane color video displays. It provides three bits per pixel corresponding to three page partitioning in each of sixteen 64K dynamic RAMs. The three bits per pixel are routed to a color lookup table, allowing for a choice of eight colors from a palette of 64 colors. The graphic display information is combined with alphanumeric video information on a pixel-by-pixel basis. This combined information is then converted from a digital signal to an analog signal. The page mode reads access three color planes for video display cycles using a counter for the two least significant memory column address bits. To create the displayed image, vectors are drawn three times, once at each plane.
Another significant patent is the Modular power supply system. This invention is a power distribution system intended for use in a highly modular desktop computer system. It provides a programmable modular DC power supply, including a power module that produces a first fixed regulated DC voltage. This voltage is coupled from the power module to a power bus, which is then distributed to a plurality of DC-to-DC converters. Each converter is operable to change the first DC voltage to a second regulated DC voltage selected from a variety of programmed voltage values.
