    Abstract: A display FIFO memory management system and method includes a programmable FIFO emulator for emulating a drain and fill time of the display FIFO memory to automatically predict a number of register entries remaining in the display FIFO memory at each predefined clock cycle. A programmable timer/counter has programmable precision to accommodate varying bandwidths of display screen display modes and is used to determine the number of entries remaining so that the emulator can accommodate varying screen display modes. A FIFO controller controls the timing of fetching display data from memory to fill the display FIFO memory based on the prediction of the number of remaining register entries in the display FIFO by the programmable emulator.

    Abstract: The present invention provides a personal propulsion device including a body unit having a center of gravity, where the body unit includes a thrust assembly providing a main conduit in fluid communication with at least two thrust nozzles, with the thrust nozzles being located above the center of gravity of the body unit. The thrust nozzles are independently pivotable about a transverse axis located above the center of gravity, and may be independently controlled by a single common linkage. The present invention may further include a base unit having an engine and a pump, which provides pressurized fluid to the body unit through a delivery conduit in fluid communication with both the base unit and the thrust assembly.

    Abstract: A method and system to automatically align overlaying video data on a computer screen based on input information of R or G or B data, horizontal synchronization signal data (Hsync) and vertical synchronization signal data (Vsync) automatically reconstructs a pixel clock time base of an offboard underlying graphics source for use in aligning overlaid video using a generated vertical pixel pattern. The system and method also automatically detects a size of an active computer screen region and position of a top left hand corner and a bottom right hand corner of the active computer screen region to align overlaying video using the reconstructed pixel clock time base and a single color block pattern.
