  • Publication number: 20040081346
    Abstract: A computerized method and system for non-intrusive testing of an information processing system. This includes stimulating a system-under-test, capturing an image from the system-under-test visual output and one or more of the following: converting the captured image to a grey-scale bitmap, deriving pixel patterns from sub-portions of the captured image, normalizing the derived pixel patterns, scoring pixels in a pixel pattern according to color intensity, comparing pixel patterns with graphical object definitions, and finding and outputting matches taking into consideration tolerances for color, resolution, object spacing and overlap, and font kerning variation. The output is optionally a text string representing the recognized text within the captured image. The method and system also automatically learns new graphical object definitions when appropriately provided with graphical objects.

  • Patent number: 5890995
    Abstract: An interactive exercise apparatus engages a user's mind and body. The apparatus comprises an exercise mechanism, a steering mechanism, and a control mechanism for manipulation by the user to achieve exercise, to indicate a direction of motion, and to interact with virtual objects in a simulated environment. The exercise mechanism can be, for example, the steps of a stair climbing simulator or the pedals of a bicycle, preferably a recumbent bicycle. A simulated environment (e.g., an interactive simulated three-dimensional environment or an interactive simulated three-dimensional fluid environment) is generated by a computer and displayed on a display system for the user. In one embodiment, the simulated environment comprises an enclosed space representing a game field. In this embodiment, an interactive competitive ball game is played using networked exercise apparatus.

  • Patent number: 5879826
    Abstract: A polymer electrolyte membrane fuel cell using hydrogen as the fuel and oxygen containing air as the oxidant. The fuel cell including a hydrogen side electrode; an air side electrode; an electrolyte positioned between the electrodes; a hydrogen diffuser/collector plate including hydrogen channels; and an air diffuser/collector plate including air channels. A method of operation of the fuel cell including introducing hydrogen into the hydrogen channels and introducing air into the air channels at a pressure of less than 5 psig and with a channel velocity of between about 0.15 and 7.0 meters/second.

  • Patent number: 5591059
    Abstract: A water ski having an elongated body of generally uniform thickness from its nose to its aft end, and including a body having a nose portion which inclines gradually upwardly, a forward body portion, and a rear body portion. The forward body portion has a width which is generally uniform and which is like that of a conventional water ski. The rear body portion extends rearwardly from the forward body portion and has side edges which diverge outwardly and rearwardly toward the rear end of the ski, with the width of the ski at its rear end being at least 150% of the width of the forward body portion. The longitudinal length of the rear body portion is from 25 to 75% of the length of the ski.
