Abstract: A power contactor can include a first conductive terminal, a second conductive terminal, a power overlay having a conductive backplane and solid state switches, and a controller module configured to selectively operate the solid state switches to enable conductive communication between the first conductive terminal and the second conductive terminal.

Abstract: A piston for use in 4 Cycle reciprocating Internal Combustion Engines. The one embodiment includes a multifunctional Engraving or Imprint that is machined into the crown of the piston. This “Imprint” consists of concentric circles of metal removed in a machining process resulting in the compartments of the functional areas within the crown of the piston connected by either the height and or cross drillings within the Imprint. The functional result is to create low and high pressure zones within the crown of the piston as it proceeds upward on the compression stroke facilitating the creation of an active moving rotational swirl in the outer 25% on the top surface area of the piston circumference. The active swirl pattern results in ultimate homogenization of the air fuel mixture leaving no area of the combustion chamber with weak or separated air and fuel molecules resulting in enhanced power and complete combustion.

Abstract: A sealed feedthrough connector can include a non-conductive clamp plate having at least one first conductor aperture and further including at least one conductor having a first end connecting to electronics in a high-power electronics chassis. The conductor can include a second end connecting to a circuit external to the electronics chassis, with a shoulder between the first and second ends. The connector can include a non-conductive terminal panel, a plate seal, and a conductor seal, the terminal panel having at least one second conductor aperture. The non-conductive clamp plate can be secured to the non-conductive terminal panel with a wall of the electronics chassis and the plate seal between them. At least one conductor can extend the first end through the first conductor aperture and the second end through the second conductor aperture, the conductor seal being positioned between the shoulder and the clamp plate or the terminal panel.

Abstract: An LED night-light includes a housing and a toggle switch mounted on the housing. First and second prongs are supported by the housing. An LED driver circuit is electrically connected to a light-emitting diode. Movement of the toggle switch to a first position presses a second conductor against the second prong and thereby switchably connects the second conductor to the second prong. Movement of the toggle switch to a second position allows the second conductor to move out of contact with the second prong and thereby switchably provides an open circuit between the second conductor and the second prong. Electricity is supplied to the light-emitting diode and to the LED driver circuit when the toggle switch is in the first position. No electricity is supplied to the light-emitting diode and LED driver circuit when the toggle switch is in the second position.

Abstract: A low-radiance infrared airborne calibration reference is an infrared imaging and calibration method. The method includes positioning a mirror perpendicular to an optical axis of a focal plane array in both an open-face position and a mirror-reading position. Temperatures of a lens, window, and the mirror are determined. In-band radiance and offset is calculated to generate an adjusted calibration curve.
