The present invention provides a process and apparatus for utilizing waste heat to power a reconfigurable thermodynamic cycle that can be used to selectively cool or heat an environmentally controlled space, such as a room or a building. Several embodiments of the rearview mirror assembly each comprise a mirror housing, a mirror disposed in the mirror housing, and some structure to allow extension of the mirror between an inboard position and an outboard position. Such techniques can be used to offer image-based products for sale over a computer network such as the Internet so that the user can change attributes of the image-based products before ordering. The whole-blood system also has a sample element that is situated in the optical path of the beam. Each contact element extends to form a point such that during installation in a direction of impact that is oriented inwards and in an essentially radial manner, the point penetrates the cable sheath and produces an electrical contact with the cable shield.
