    摘要: An improved stepped etalon comprises a transparent body having a stepped surface. Adjacent step lands are separated from each other by a transition region which includes a curved, waved, or otherwise varied step wall such that the average height of the stepped surface does not change abruptly in the transition region from the height of one land to another, but instead varies gradually according to the particular shape of the step wall. In an alternative embodiment, the step transition is formed using a grey-scale or half-tone patterning in which the average height gradually varies across the transition region. The non-planar transition region reduces the amount of coherent interference caused by the step transition thereby reducing the dead spot behind the step transition portions where interference prevents accurate measurements of light transmission from being made.

    摘要: A cooling system assembly for a vehicle includes a heat exchanger with a plurality of fins for the transfer of heat to air passing therebetween. The heat exchanger has a pre-selected length, width, and thickness such that the heat exchanger fits adjacent an engine of the vehicle. A plurality of fan assemblies are positioned adjacent each other and juxtaposed the heat exchanger so that the fan assemblies cause air to travel across the fins when the fan assemblies are operating. Mounting brackets protrude from a periphery of each of the fan assemblies. Each of the mounting brackets has a set of ratchet grooves formed thereon and a bore extending therethrough. A bracket member is associated with each of the plurality of mounting brackets that connects the mounting bracket to either the heat exchanger or to one of the mounting brackets of the other fan assembly.
