Abstract: A system and method for acquiring three-dimensional images of a magnetic flux leakage present in steel tendons, which are embedded in concrete and/or grout. The inventive method magnetizes the steel tendon. Transducers detect the intensity of the magnetic field along the steel tendon. Using this magnetic intensity, three dimensional images of the magnetic flux leakage are generated using a data acquisition and computing device.

Abstract: A system for reducing idle time in service vehicles such as police patrol cars. A bank of auxiliary batteries is provided. An electrically-powered auxiliary air conditioning compressor is also provided. The auxiliary air compressor is connected to the discharge and suction lines of an existing an conditioning system so that it can propel refrigerant through an existing refrigerant circulation loop. When the vehicle's internal combustion engine is switched off, the auxiliary batteries are selectively used to power the auxiliary air-conditioning compressor in order to provide cooling for the vehicle's cabin. The auxiliary batteries are also used to provide electricity to the vehicle's other electrical loads—such as emergency lights.
