Abstract: A liquid heat sink is provided that employs natural convection of a liquid coolant (18') to cool a printed circuit board (14) on which are mounted a plurality of heat-generating components (12). In particular, the spacing d between the heat-generating components and a cold plate (20) used to cool the liquid must be such as to provide a Rayleigh number of at least about 1700 in the Rayleigh equation: ##EQU1## In the above equation, g is the acceleration of gravity, .beta. is the volumetric coefficient of expansion of the liquid coolant, T.sub.1 is the temperature of the cold plate, T.sub.2 is the temperature of the component to be cooled, .nu. is the kinematic viscosity of the liquid coolant, and .alpha. is the thermal diffusivity of the liquid coolant.

Abstract: A heat transfer device for use with a heat sink in removing thermal energy from an integrated circuit chip. The inventive device includes a first membrane of flexible, thermally conductive material having a first surface in contact with the integrated circuit chip. A flexible, thermally conductive radial finger contact spring is disposed in contact with a second surface of the first membrane. A second membrane of flexible, thermally conductive material is included. The second membrane has a first surface in contact with the spring and a second surface in contact with the heat sink.

Abstract: A method and apparatus for simultaneously recording multiple Fourier Transform Infrared (FT-IR) signals using an interferometer. The analog signals are coupled to switching means which is operable in response to a first control signal for synchronizing the operation of the interferometer and the control circuits and a second control signal for defining data acquisition intervals to direct the sampled data of the analog input signals over a circuit path including Sample and Hold and Analog to Digital Conversion circuits to a processor for storing the digital data corresponding to the analog input signals. The switching means is operated so that samples of the analog input signals are taken in sequence and stored in sequential storage locations in interleaved fashion. The processor is operable under program control to access the digital data so that all data samples for the same input signals are separated to produce an interferogram for each of the input signals.
