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: A photographic recording arrangement to be mounted in a motor vehicle, particularly for use by law enforcement personnel, is described. The arrangement includes a camera of specific construction which is mounted on the dashboard and is capable of automatically taking, on a reel of film, sequential frames of pictures of the vehicle under observation, thus recording the license plate thereof, as well as the behavior of the driver handling the vehicle and, in another sequence, photographically recording, in a given number of frames, the speedometer reading of the car in which the camera is mounted.

Abstract: An accessory device for lighting fixtures is described. It comprises a pair of telescoping tubular housings having at one end a standard screw terminal adapted to fit a conventional electric socket and, at the other end, a standard electric lamp socket. Electrically conductive connections are provided within the housings for interconnecting the end terminals at any position of extension of the housings.
