Abstract: The disclosure generally relates to a heat exchanger apparatus having first and second heat exchangers arranged in a parallel configuration to receive a first fluid (e.g., a hot fluid) to be subjected to a heat exchange operation (e.g., cooling of the hot fluid). The first and second heat exchangers are further configured in a series configuration with respect to the flow of a second fluid to be used as a heat exchange medium (e.g., a cold fluid to be heated by the first, hot fluid). The heat exchanger apparatus can be used as a radiator (e.g., engine coolant heat exchanger) for a motorized vehicle, in particular a heavy vehicle intended for use in relatively hot ambient environments (e.g., an armored fighting vehicle adapted for desert use at ambient temperatures above about 100° F.). The disclosure also relates to methods of using the heat exchanger apparatus, for example in the motorized vehicle setting.

Abstract: A method and apparatus for a physical training device is provided to accommodate one or more athletes during support of a plurality of independent training scenarios for each athlete. The physical training device provides a plurality of training stations, where each training station may be specific to martial arts training activities, or may be generalized to facilitate training that is effective for a plurality of other sporting disciplines. The physical training device provides removable casters that facilitate maneuvering and reconfiguration of the physical training device. Lifting devices may also be configured along the bottom surface of the physical training device so as to provide a mechanism whereby the casters of the physical training device may be lifted off of the surface that is supporting the casters. Two or more physical training devices may be interconnected so as to provide a localized cluster of physical training devices.
