Abstract: A linear pump includes a housing having a bore and axially spaced apart inlet and outlet. A first check valve is joined to the housing for controlling flow of fluid through the bore. A piston is disposed coaxially in the housing bore for axial translation therein and includes a piston bore and axially spaced apart inlet and outlet. A second check valve is joined to the piston for controlling fluid flow through the piston bore. A linear motor includes a plurality of axially adjoining drive coils disposed in the housing, and a pair of axially spaced apart magnet rings disposed in the piston and spaced radially inwardly of the drive coils for magnetically cooperating therewith to axially oscillate the piston in the housing for cyclically pumping the fluid in turn through the housing and piston inlets and outlets in unidirectional flow through the housing and piston bores.

Abstract: The keyboard assembly for a computer with movable keyboard pallets. The pallets are movable relative to each other between a compact stowing position and an extended operational position. A movement mechanism moves at least one of the pallets in a lateral direction relative to the other pallet and then towards the other pallet in a direction orthogonal to the lateral direction. The movement mechanism can be connected to the cover of the computer to automatically control movement of the pallets based upon position of the cover relative to a base of the computer. Thus, the pallets can be automatically moved from the compact stowing position, when the cover is closed, to the extended operational position when the cover is opened. Upon moving the cover from the open position to the closed position, the pallets are automatically moved from the extended operational position to the compact stowing position.
