A method and apparatus used for actuation is provided. In one embodiment, the apparatus comprises an actuation body having a gradually tapered wider end received at one end by an expandable member and at an opposing end by a drive shell. The actuation body being movable from a first position to a second position by means of the drive shell such that this movement causes a looser or tighter fit at the wider end with respect to the expandable member.

An exemplary embodiment is a multiple card enclosure including a mother card cage having a mother card enclosed therein and a daughter card removably positioned within the cage for connecting the daughter card with the mother card. The daughter card includes a power tab extending from a first edge defining the card and a signal connector extending from a second edge perpendicular to the first edge. The signal connector is configured to connect to the mother card for signal interconnection therebetween. A guide means is configured to guide the daughter card into the mother card cage and in signal interconnection with the mother card and is configured to provide power into and out of the daughter card via connection with the power tab.

A method for cooling electronic components in a rack, the method comprising: circulating a first liquid from a cold plate to one of a plurality of heat exchangers mounted within the rack; circulating a second liquid from a second liquid supply to the one of a plurality of heat exchangers; and transferring heat from the first liquid to the second liquid at the one of a plurality of heat exchangers.
摘要:
An integrating sphere, and an integrating sphere-based reflectance colorimeter/spectrophotometer for the measurement of color and appearance, having multiple receivers capable of concurrently receiving optical radiation scattered/reflected from a diffusely illuminated sample surface, with the capability of multiple measurement modes (e.g., multiple specular component excluded (SCE), SCE and specular component included (SCI), multiple SCI), multiple areas-of-view for a given measurement mode, multiple viewing angles per measurement mode, and combinations thereof. An embodiment of the invention includes two SCI receivers and two SCE receivers, each disposed at an equal viewing angle relative to the sample surface. For each viewing mode, two sample areas-of-view are provided. The SCE receivers are opposite each other, such that the specular component of each SCE receiver is excluded by the port of the other SCE receiver. The receivers provide the collected light reflected from the sample to a detector which preferably is provided by multiple spectrometers or a single spectrometer having multichannel capability to preferably sense the light from each receiver in parallel.
