Abstract: An economical position-sensing muon detector for muon radiography is constructed using a pair of glass plates spaced apart by crossed parallel barriers. Smaller detector wires are interspersed between the barriers and an ionizing gas is used to fill the space between the plates. A muon striking near where detector wires cross causes a local momentary current flow. The current flow in two of the detector wires is sensed to determine the coordinates of the muon impact. Such muon detectors can be assembled in modular surface arrays and such arrays can be positioned on spatial surfaces for differential inspection and detection of muons transiting through and emanating from objects placed within the inspection space. Such a detector constitutes a novel and useful invention in providing an inspection device and means for cargo or cargo vehicles that detects muons transiting through and emanating from hazardous materials intended to cause malicious harm.

Abstract: A rescue device with a GPS receiver, a computer, and vibration sensors. The device detects and distinguishes vibrations and sends a radio message to a Low Earth Orbit satellite that relays messages to a monitoring facility indicating the type of vibration detected. The geographic location of the device is included in the message. The entire device is constructed to resist vandalism and to permit it to be dropped from an aircraft for installation.

Abstract: A multiplayer electronic entertainment system with a central simulator style device surrounded by a plurality of video game style devices. The simulator style device has a two-player cab with collimated visual displays. The two-player cab is mounted on a hydraulic motion base. Each video game style device is fixed and has a direct view cathode ray tube display. All game devices are interconnected via an Ethernet switch, so that each participant is visible to the others in the electronic imagery that is created on the game devices.
