Abstract: The suspension system for a trailer is disclosed. The suspension system includes a torsion axle and an air spring operating to accommodate a wide range of a load weight applied to the trailer without any change in ride comfort. The air spring can be adjusted for its pressure inside to cover a heavy load weight, while the torsion axle can have relatively softer spring materials therein to cover a light (and zero) load weight. The air spring and the torsion axle are arranged in series to provide adequate suspension based on the load weight.

Abstract: An energy storage/battery system is disclosed. The system can include a multi-voltage configurable module (MVCM) and a multi-voltage configurable backplane (MVCB) that form the system. The system can be dynamically controlled to bring MVCMs on or offline to deliver power and capacity to a device.

Abstract: A launch cable assembly for use with an MPO switch and OTDR to test a multi-fiber cable, which includes a mandrel around which is wrapped between twenty-five and two hundred feet of multiple fiber optic strands, where the mandrel and fiber optic strands are housed within a housing, the fiber optic strands are in optical communication with a port in the housing, the fiber optic strands exit the housing from a fiber exit in the housing, and the fiber optic strands terminate in an assembly connector, which is preferably a standard MPO connector.
