Abstract: A real-time wireless video exposure monitoring system comprising an exposure monitor, located at a field site, which detects the level of an environmental contaminant and supplies corresponding data via a serial data port to a serial-to-wireless bridge for real-time wireless transmission of the data to a wireless Internet access point. The system includes a video camera at the field site and a wireless video connection for transmitting video images from the video camera in real time to the wireless Internet access point. A client computer, which may be at a central station at a distant location, is adapted to connect via the Internet to the wireless bridge and the wireless video connection so as to receive real-time contaminant level data and real-time video, the client computer configured to provide real-time data recording and analysis.

Abstract: A real-time video radiation exposure monitoring system comprising a Geiger-Müeller meter and a video camera linked to a computer programmed to display video images from the camera simultaneously with data from the Geiger-Müeller meter. A radio modem provides wireless data communications between the Geiger-Müeller and the computer. One aspect of the invention is a retrofit of a conventional Geiger-Müeller meter to include a microcontroller with internal A/D converter enabling the meter to output instantaneous measurements in RS-232 serial format.

Abstract: An ergonomic tool handle (21) which is useful for a terminal insertion hand tool, gardening hand tools, knives, box cutters, screwdrivers and other pushing or pulling type hand tools. The tool handle (21) of the present invention is contoured to promote neutral posture between the hand and wrist as well as complementing the shape of the closed hand to distribute longitudinal tool forces evenly throughout the hand and arm of the user. The tool handle (21) accomplishes this neutral posture and contoured fit by featuring a humplike crown (28) which fits snugly into the pocket of the palm, a relatively flat underside (29) around which the user's finger tips (55-57) are wrapped and two sides (51, 52) with convex regions (30, 31) in diagonally offset relation. By moving one's hand up or down the tool handle (21), one size of tool handle (21) can ergonomically fit approximately 95% of male and female hand sizes.
