Abstract: A method of constructing a roadway having an embedded linear synchronous motor (LSM) utilizes prefabricated modules. Structurally, each module comprises a top plate, a multiple-phase winding tied to the top plate, and a concrete mold encapsulating the winding. With the modules prefabricated, the roadway is constructed by first excavating a trench to position a foundation at the trench bottom. Then a mud matt is positioned on the foundation. Next, the modules are laid end-to-end on the mud matt. Thereafter, the windings in adjacent modules are electrically interconnected through joints. Further, the joints are covered by junction boxes, and the trench around the roadway is filled in with aggregate.

Abstract: A system for controlling movements of a vehicle along a guideway includes an array of targets that are mounted on the vehicle, and a series of wayside sensors that are mounted on the guideway. A signal processor monitors the passage of targets past appropriate sensors and uses resultant signals to derive parametric values that are characteristic of the vehicle's movements. The parametric values are then coordinated with a controller for the operation of a linear synchronous motor that propels the vehicle.

Abstract: A device for activating a signal emitter for use in a firefighter locator system operates in conjunction with the firefighter's self-contained breathing apparatus (SCBA). The activation device includes a pressure sensor to monitor pressure on an air line that delivers air from the SCBA air tank to the SCBA air regulator. When the firefighter opens the SCBA air tank valve, pressure is sensed in the air line and the emitter is activated to transmit a signal. The signal is received by base stations that then use the signal to locate/track the signal emitter. Preferably, the activating system also includes a user operated reset button(s) and a shutoff circuit to allow the user to stop transmission of the signal by the signal emitter. The shutoff circuit is designed to stop transmission of the signal only after the air line has been depressurized and the reset button(s) is depressed.
