Abstract: A maze construction system for fire and rescue training exercises includes a plurality of panels that are tensionably supported between a ceiling and floor. Each panel includes at least one extendable column that terminates with a pad for contact with a ceiling surface. A flange along at least one vertical edge of the panels permits the panels to align at their edges. The panels are quickly assembled and disassembled, and are easily reconfigured to form new maze paths without requiring additional additional tools.

Abstract: A maze construction system for fire and rescue training exercises includes a plurality of panels that are tensionably supported between a ceiling and floor. Each panel includes a pair of extendable columns that terminate with a pad for contact with a ceiling surface. A flange along at least one vertical edge of the panels permits the panels to align at their edges. The panels are quickly assembled and disassembled, and are easily reconfigured to form new maze paths without requiring additional tools.

Abstract: A receiver hitch rack system and apparatus for providing storage of receiver hitch devices in a clean, safe, stable, and organized manner. The receiver hitch rack system and apparatus comprises a mounting device and a mounting base, wherein the mounting device may be removably attached to the mounting base, and wherein the mounting base may be attached to a structural support, which includes, but is not limited to, a stud wall, a tool box, a vehicle and a fence. The receiver hitch devices are inserted or fastened onto the mounting device, preferably tube-shaped. The receiver hitch rack system and apparatus may be stored in a vertical or horizontal manner depending upon the receiver hitch device's configuration and the space available.

Abstract: A checkstop architecture allows an entire computer system to be immediately halted when a failure(s) or error(s) has occurred at a chip, component, device, sub-system, etc. The present checkstop architecture provides a way of preserving and later providing the state of the computer system at failure or error. The checkstop architecture utilizes a single-wire checkstop that provides a way for quickly stopping all chips in the system and a JTAG that provides a way for querying the error registers in determining which chip pulled checkstop first and what had occurred to cause the error. The present system and method also utilizes a service processor, various computer devices, and at least one central checkstop collection location. The occurrence of the checkstop at one of the computer devices is detected by its internal checkstop operation. The occurrence of the checkstop is driven to the at least one central checkstop collection location, all other of the computer devices, and the service processor.

Abstract: A sequenced initialization used for maximizing detection of errors and failures and triggering of respective attention signals. A number of computer devices each having a JTAG interface, an attention distribution sub-system, and a service processor are provided. Each computer device is inaccessible during a built in self test (BIST) and is coupled to an error register bit. Fences for computer devices are put up so that the inputs are in a known state and computer devices driving the inputs have no effect. BISTs for computer devices are performed as they are released from reset. Determination of when BISTs are complete and if each BIST has passed is performed.
