A cable plug retention clip having a clip body adapted to secure a cable plug to a power distribution unit. The clip body has a first retention mechanism adapted to secure the clip body to the power distribution unit, and a second retention mechanism adapted to secure the clip body to the cable plug. A system having a power strip comprising a power outlet adapted to receive a plug of a power cord, and a plug retainer adapted to couple the plug to the power strip. The plug retainer has a first retention mechanism engageable with the power strip, and a second retention mechanism engageable with the plug.

A rack mount computing system having a keyboard and display assembly mountable in a 1 U rack space. The keyboard and display assembly are provided in a clamshell configuration to reduce space consumption of the keyboard and display assembly to facilitate mounting in the 1 U rack space.

System and method for mounting a keyboard and display assembly in a 1U rack space

A combination of a track ball mechanism and a scroll mechanism. The combination may be placed proximate a standard portion of a keyboard so that a user can access either the track ball mechanism or the scroll mechanism without removing either hand from the standard portion of the keyboard. The track ball mechanism and the scroll mechanism may be integrated with one another to some extent.

The field of the invention is an improved keying system for categorizing a consumable cartridge by using a two component system including a relatively long-lived portion and the relatively short-lived consumable cartridge. The improved system includes a lug element and a structure for mounting the lug element to the relatively long-lived portion, which may be the inner housing of a copier machine or other machine using consumable cartridges. Ideally, the lug element is self-fixturing into a void space. The consumable cartridge has portions defining a void into which the lug element projects when the consumable cartridge is inserted into the relatively long-lived portion for machine operations.

A dual bin paper feed tray is removably insertable into the standard height tray-receiving housing opening of an image reproduction machine such as a printer or copier. The tray has adjacent front and rear paper holding bin areas each configured to hold a stack of approximately 250 cut paper sheets, the overall tray thus being adapted to hold the entire contents of a standard one ream package of cut paper sheets. In operation, the loaded tray is inserted, front end first, into the housing opening and the machine's paper feed system operates to sequentially feed paper sheets from the front tray bin into the machine. When the machine's paper sensing system detects that the front bin has been emptied, a shift structure incorporating a motor-driven gear train and associated cam/follower apparatus is automatically operated to move the rear paper stack into the front tray bin for infeed to the machine.
