    • A cooling apparatus and method including a plurality of heat-producing devices positioned in a plurality of cabinets arranged in a row that allows flow of a first fluid through the heat-producing devices and cabinets where the flow is directed from an upstream end of the row to a downstream end of the row. The cabinets have a space therebetween wherein a heat exchanger is positioned between and adjacent to the cabinets, thereby the cabinets and heat exchangers alternate in the row. Each heat exchanger allows flow of a second fluid therethrough for cooling the first fluid. A fluid-moving device is positioned adjacent the heat-producing devices for encouraging flow of the first fluid through the cabinets' heat-producing devices and through the heat exchangers, thereby encouraging heat transfer in each of the heat exchangers from the first fluid to the second fluid.

    • The trajectory of an electromagnetic actuator is adjusted by pulse-width-modulating feedback control of the waveform which energizes the coil. As applied to actuators for impact printing, the objectives of the control scheme are to regulate the armature's time of flight and its velocity at impact, in spite of disturbances, thereby to provide higher-quality printing at increased speed. Each actuation is produced by energizing the coil with a series of pulses. Regulation is accomplished under microprocessor control by measuring the state variables of the system--armature position, armature velocity, and coil current--at the beginning of each pulse, comparing these measurements to ideal values, and modulating the width of the pulse as a function of the errors. In general, the appropriate functional relationship between the measured errors and the pulse-width modulation is nonlinear, and is different for each pulse in the series. Systematic means for determining these relationships are given.

    • An apparatus for cooling N heat-producing devices, where AT is an integer no smaller than one, using a cooling fluid that may be supplied at a temperature below the dew-point temperature of ambient air. To avoid condensation on the heat-producing devices, the cold fluid is warmed, upstream of the heat-producing devices, to a temperature T0 that is above the dew-point. The warming is accomplished, in a heat exchanger, by the warm fluid returning from the heat-producing devices. The amount of warming is controlled by periodically measuring T0 as well as the N temperatures downstream of the N heat-producing devices, and sending these N+1 temperature measurements to a control element that implements a control algorithm whose purpose is to achieve a set-point value of T0 by regulating, via N control valves, the flow of fluid to the N heat-producing devices. Also provided is a method for cooling the N heat-pro during devices pursuant to the inventive apparatus by a temperature control over the cooling fluid.

    • An arrangement for the cooling of computer data centers. More particularly, the arrangement eliminates the problems present in the uneven or inadequate cooling of computer racks due to unwanted airflows, which are encountered between so-called hot aisles and cold aisles present in a computer data center. Specifically, this problem is solved through the provision of partitions which, under normal circumstances, prevent the unwanted airflows by standing in a vertical orientation, yet which, in the event of a fire, collapse from the vertical orientation to a horizontal orientation, thereby avoiding interference with water sprays from sprinkler heads, and thus complying with fire codes and ordinances. Moreover, also employed is a method of preventing the unwanted air flows by utilization of the novel arrangement comprising the fire-code-compatible, collapsible partitions.
