Abstract: A cooling plate assembly for dual-sided cooling, the cooling plate assembly can include a first cooling plate and a second cooling plate. The first cooling plate that has a first cooling plate connector side and a first cooling plate cooling side that is opposite the first cooling plate connector side. The second cooling plate that has a second cooling plate connector side and a second cooling plate cooling side that is opposite the second cooling plate connector side. The second cooling plate is configured to attach to the first cooling plate such that formed between the first cooling plate connector side and the second cooling plate connector side is at least one cooling passage through which a cooling fluid is flowed to transfer heat from both the first cooling plate cooling side and the second cooling plate cooling side to the cooling fluid.

Abstract: Inverter apparatuses and systems with a DC energy source are disclosed, in which a planar and radially symmetrical positive DC busbar is coupled with a positive terminal of the DC energy source and a planar and radially symmetrical negative DC busbar is coupled with a negative terminal of the DC energy source. The inverter has a plurality of switches such that the plurality of switches are positioned radially symmetrically with respect to a center of the DC busbars. Each switch is coupled with either the positive DC busbar or the negative DC busbar on a first end and one of a plurality of AC busbars on a second end. A single toroidal filtering core is located at the center of the DC busbars and is coupled with the plurality of AC busbars.

Abstract: A method of making a piston for an opposed-piston engine comprises providing a piston. The piston comprises a substantially cylindrical portion including a sidewall and a piston crown located at an end of the piston. The piston crown comprises an end surface structured to form a combustion chamber when disposed within a cylinder bore in cooperation with an end surface of a cooperating opposing piston. A bonding layer including a bonding material is deposited on the end surface of the piston crown using a high velocity oxy-fuel spray process. At least one thermal barrier layer comprising ceramic material is deposited above the bonding layer.
