Abstract: A vapor-compression multi-evaporator cooling system comprises a cooling control system and two or more evaporators each coupled to an expansion valve. Each evaporator is selectively enabled or disabled during operation. When an evaporator is enabled, the evaporator transfers heat into a working fluid within the system. When an evaporator is disabled, the evaporator does not exchange any appreciable amount of heat within the system. The cooling control system includes a cooling controller, an adjustable compressor, a condenser, and a variable speed fan that provides selectable amounts of cooling to the condenser. During operation, the cooling controller adjusts the compressor operation and fan speed to maintain stable operation of the cooling system. To compensate for enabling or disabling of evaporators, the cooling controller adjusts compressor operation and fan speed to provide more or less compression and more or less condenser cooling to maintain stable and efficient operation of the cooling system.

Abstract: An integrated circuit is wire bonded in a manner such that there is consistent RF performance from integrated circuit package to integrated circuit package. Bond distances within the integrated circuit are measured, each corresponding to a wire bond to be formed. An area under a hypothetical wire bond profile is calculated as a function of the bond distances, a baseline wire length, and a baseline loop height. A wire is bonded across a given one of the bond distances to form a given one of the wire bonds. A wire bond profile for the given wire bond is provided having an area thereunder that is substantially equal to the calculated area.

Abstract: A variable stator vane assembly and a bushing thereof. The bushing includes a metal bushing body and a wear-resistant coating. The assembly includes a rotatable trunnion and a first metal bushing. The trunnion is capable of being located in a through hole extending between outer and inner surfaces of a compressor casing of a gas turbine engine. The first metal bushing is capable of being located in the through hole proximate the outer surface to surround a first portion of the trunnion when the trunnion is located in the through hole. The first metal bushing and the first portion have wear-resistant coatings which are in mutual contact, apart from any intervening lubricant, when the trunnion and the first metal bushing are located in the through hole and the trunnion is rotating with respect to the first metal bushing.

Abstract: The present invention relates to the use of sigma-2 agonists to potentiate the activity of antineoplastic agents. These substances are useful for treating cancerous tumors and, in particular, drug resistant tumors in humans. Methods for sensitizing multidrug resistant cells to antitumor agents comprising contact the cells with a sigma-2 agonist are also described.

Abstract: The present invention relates to sigma-2 receptor agonists and their use in the treatment of immunodeficiency virus infections, especially human immunodeficiency virus (HIV) infections. The invention particularly relates to sigma-2 agonists, especially CB-184 and its analogues, that decrease cellular production of sphingomyelin when provided to recipient cells, and inhibit HIV replication.

Abstract: A method facilitates assembling a variable vane assembly for a gas turbine engine including a casing and an inner shroud. The method comprises providing at least one variable vane including a radially inner spindle that includes a groove defined therein that has at least one machined face, and coupling the variable vane radially between the casing and the inner shroud such that at least a portion of the radially inner spindle is inserted at least partially through an opening extending radially through the inner shroud. The method also comprises securing the variable vane to the inner shroud by engaging the spindle machined face with a retainer coupled to the inner shroud.

Abstract: The present invention relates to a class of compounds having affinity for certain cancer cells, e.g. lung carcinomas, colon carcinomas, renal carcinomas, prostate carcinomas, breast carcinomas, malignant melanomas, gliomas, neuroblastomas and pheochromocytomas. The compounds of the present invention can also bind with high specificity to cell surface sigma receptors and can therefore be used for diagnostic imaging of any tissue having an abundance of cells with sigma receptors. The present invention provides such compounds as agents for diagnostic imaging and for detecting and treating tumors containing the cancer cells described above.

Abstract: There is disclosed a power amplifier includes an in-phase power splitter generating two split signals from an input signal, and two amplifiers capable of operating in different modes. The split signals are provided as respective inputs to the two amplifiers which are coupled through transmission lines such that as the first amplifier approaches the maximum power it can produce, the output from the second amplifier begins to contribute to the power amplifier output and supplements and modifies the power provided by the first amplifier thereby extending the range of input power over which the power amplifier delivers output power.

Abstract: An apparatus which aligns a ball grid array (BGA) device over a substrate. The apparatus preferably includes a cup-shaped member for cupping and holding the solder balls of the BGA device, and an elongate member attached to the cup-shaped member. The cup-shaped member is attached between the BGA device and the substrate at two or more different positions so that the solder balls of the BGA device become aligned over the terminals of the substrate by operation of gravity.

Abstract: A transmission line balun transformer for providing a single ended output signal from a pair of differential input signals includes two transmission line signal couplers. The couplers are individually designed to be relatively loosely coupled devices, i.e. having a coupling factor greater than 3 dB, but are coupled together with proper phase relationships so as to achieve a relatively tighter composite coupling characteristic in the order of 3 dB, thereby resulting in an increase in bandwidth.
