Abstract: An energy storage pack includes a coolant inlet manifold, a coolant outlet manifold, and a plurality of thermal-exchange tubes extending between the coolant inlet manifold and the coolant outlet manifold to exchange heat between coolant passing through the plurality of thermal-exchange tubes and a plurality of battery cells mounted adjacent to and among the plurality of thermal-exchange tubes within the energy storage pack. In one embodiment, at least one of coolant inlet manifold and the coolant outlet manifold includes a plurality of thermal-exchange tube terminating structures and a plurality of hose segments intercoupling the plurality of thermal-exchange tube terminating structures. The energy storage pack may further include a coolant inlet opening located on the coolant inlet manifold and a coolant outlet opening located on the coolant outlet manifold.

Abstract: Impact protection structures for vehicles are described. An impact protection structure includes a support structure of the vehicle, an interior rail coupled to the support structure, and an exterior rail coupled to the interior rail. The exterior rail has an inboard boundary wall positioned between an upper mounting region and a lower mounting region. The upper and the lower exterior mounting region of the exterior rail are coupled to an upper and a lower mounting region of the interior rail. At least a portion of the inboard boundary wall is spaced apart from an outboard wall of the interior rail such that when the exterior rail is impacted by a blunt-object barrier, the inboard boundary wall of the exterior rail deforms, thereby damping energy of the impact at the exterior rail and arresting crack propagation between the exterior rail and the interior rail.

Abstract: A liquid extraction cleaning device comprises a main unit, a liquid pump, a flexible hose, and a hand tool. The main unit comprises a vacuum pump.
