Abstract: An actuation assembly and method is described for a computing environment comprising a main housing and a (first) wedge complementary to the main housing. This wedge is connected to the housing at least partially such that this wedge and the main housing form a unitary housing entity. The wedge is also formed such as to house a lead screw on one of its sides. A plurality of slide mechanisms is also provided. The slide mechanism is connected to opposing sides of the main housing and the wedge. A drive wedge is also provided. The drive wedge is connected to the main housing and the first wedge and formed such that it can be moved from a first position to a second position via a lead screw.

Abstract: The fluid circuit for a hematology analyzer includes a block-like plastic member with passageways for fluid, and a reaction chamber recess that communicates with one or more of the fluid passageways. A detachable metallic heat transfer cover member is positioned across the reaction chamber recess to close the reaction chamber recess and establish a confined reaction chamber. A heater is placed in conductive contact with the metallic heat transfer cover member to heat the cover member and thereby conduct heat to the reaction chamber. The metallic heat transfer cover member is detachably secured to the block-like plastic member and can thus be removed and replaced as needed.

Abstract: A connector for attaching a printed circuit board to other apparatus is formed as a separate connector body with a plurality of pins projecting from one end surface that are attached to the printed circuit board by being secured in vias through the board and a threaded opening at the end surface opposite the one end surface from which the pins project. When a bolt is received in the connector threaded opening and drawn tight to secure the printed circuit board to other apparatus, the stresses and material deformation induced by the securing bolt are isolated from the printed circuit board. Further, the attachment of the pins to the printed circuit board rather than the use of screws extending through holes in the circuit board reduces the size of ‘keep out’ zones that must be avoided by the wiring paths on each wiring surface of the printed circuit board through which mounting holes extend.
