Abstract: In one aspect, the invention is a novel and non-obvious design for wind fan or wind turbine that 1) can adjust to changes in wind direction and 2) is collapsible or retractable when desired. Further, the invention relates to a novel and non-obvious design for a fan blade assembly that allows for the ability of the wind turbine to adjust to changes in wind direction and allows for the wind turbine to collapse or retract into a housing when not in use.

Abstract: A tire monitoring (TM) system includes a peak detector signal filter that is configured to substantially prevent impulse noise from increasing a data slicer threshold, while simultaneously allowing the data slicer threshold to follow the variations in a received message attributable to signal fading. The TM system also automatically determines the location of a plurality of vehicle tires relative to the vehicle, utilizes a single receiver to receive messages of multiple lengths and masks an alarm when a missing ID code corresponds to a stored ID code associated with a flat tire.

Abstract: Conventional bit-mapped address locations in a character oriented video random access memory (RAM) in which each character is represented by a bit mapping array comprised of ten lines each including eight pixels, or eight bits of information, in an X-Y matrix address organization are redefined in terms of the character and row address locations of a graphics oriented cathode ray tube controller for driving a video display. Groups of bits in the X-Y matrix address locations of the video RAM are shifted in a predetermined manner in generating a redefined, 1:1 mapping function addressing code which is provided to a cathode ray tube controller for driving the video display. A video RAM mapping module is provided for reorganizing the video RAM addresses and translating these addresses throughout the page of the video RAM in providing more efficient graphics mapping while retaining high resolution alphanumeric character video resolution.
