Abstract: A method of and apparatus for cooling heat-generating devices in a cooling system is disclosed. The apparatus includes various sensors, control schemes and thermal models, to control pump flow rates and fan flow rates in a concerted manner, while minimizing power consumption, noise, and noise transients. The apparatus further includes at least one heat-generating device, at lease one heat exchanger, and at least one heat rejector. The apparatus can also include many pumps and fans.

Abstract: A cholesteric display may be formed, in some embodiments, using a single display element to produce multi-colors for display. A cholesteric material may be sandwiched between a pair of substrates, each associated with pairs of opposed electrodes that are arranged in general transversely to the optical axis of incident light. The first pair of electrodes produce one of two liquid crystal states and result in the reflection of light of a particular wavelength. Light of other wavelengths may be reflected when a second pair (or set) of opposed electrodes, arranged in general transversely, also to the optical axis of incident light, are biased appropriately. So does a third pair (or set) of electrodes. A black and white color display may be generated from a single display element by modulating the pitch length of the cholesteric material within each pairs (or sets).

Abstract: A power management apparatus includes a sensor and a display coupled with the sensor. The display is powered off when the sensor detects absence of a user and the display is powered on when the sensor detects presence of the user.
