Abstract: An integrated linear generator system includes, for example, a generator assembly, a control system, a frame system, an exhaust system, an intake system, a cooling system, a bearing system, one or more auxiliary systems, or a combination thereof. The generator system is configured to generate power, as controlled by the control system. The generator assembly may include an opposed- and free-piston linear generator, configured to operate on a two-stroke cycle. The intake and exhaust systems are configured to provide reactants to and remove products from the generator assembly, respectively. The cooling system is configured to effect heat transfer, material temperature, or both, of components of the integrated linear generator system. The bearing system is configured to constrain the off-axis motion of translators of the generator assembly without applying significant friction forces.

Abstract: Systems and assemblies are provided for sealing an interface between a cylinder and a manifold corresponding to the cylinder. The cylinder comprises at least one port. A manifold interface is arranged adjacent to the at least one port. A seal is located inside of a circumferential pocket, wherein the circumferential pocket comprises at least a portion of the manifold interface. A spring is configured to preload the seal radially inward so that the seal stays in contact with the outer surface of the cylinder.

Abstract: A display system includes a graphics controller, a difference injector, a display controller, a power measurement circuit, an arithmetic controller and an error detector. The graphics controller provides an image frame to the difference injector. The difference injector modifies the image frame by a known image artifact, and provides the image frame and the modified image frame to the display controller. The display controller displays the image frame and the modified image frame at a display screen. The power measurement circuit measures a first power characteristic of the display screen during the display of the image frame and a second power characteristic of the display screen during the display of the modified image frame. The arithmetic controller determines a differential power characteristic based on the first and second power characteristics. The error detector determines whether the differential power characteristics are indicative of the display of a known image artifact.
