Abstract: A display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated with backlight illumination from a direct-lit backlight unit. The backlight unit may include an array of light-emitting diodes (LEDs) on a printed circuit board. The display may have a notch to accommodate an input-output component. Reflective layers may be included in the notch. The backlight may include a color conversion layer with a property that varies as a function of position. The light-emitting diodes may be covered by a slab of encapsulant with recesses in an upper surface.

Abstract: An integrated drive generator for an aircraft and a method of making and operating the same result in improved operation of the integrated drive generator, especially during cold start-up. This is accomplished through the use of at least one stop to prevent each of the cylinder blocks in the hydraulic pump and motor assembly of the integrated drive generator from moving away from the port plate more than a predetermined amount which will ensure establishment of hydraulic continuity between the pump and motor without substantial delay during cold start-up of the integrated drive generator.

Abstract: A torque transmitting apparatus which includes a tubular drive shaft defining a deaeration chamber integral with the interior of the shaft. Aerated liquid is ducted into one axial end of the deaeration chamber and separated air and residual liquid are ducted from the opposite end of the chamber, generally near the center thereof. Relative rapid rotation of the drive shaft causes radial acceleration of the liquid to effect separation of the more dense liquid from the air under the influence of centrifugal force. The deaerated liquid is ported from the outer periphery of the chamber during rotation of the drive shaft.

Abstract: A governor for controlling a hydraulic transmission including a housing, a flyweight assembly rotatable within the housing, an axially movable hydraulic transmission control valve within the housing connected to the flyweight assembly for axial movement in one direction within the housing in response to rotation of the flyweight assembly within the housing, a spring axially biasing the valve for axial movement in the opposite direction within the housing, means for sensing an underspeed condition of the transmission and including hydraulic elements responsive to the underspeed condition in excess of a predetermined condition for axially shifting the valve.
