摘要： The present invention is a MEMS-based two-phase LHP (loop heat pipe) and CPL (capillary pumped loop) using semiconductor grade silicon and microlithographic/anisotropic etching techniques to achieve a planar configuration. The principal working material is silicon (and compatible borosilicate glass where necessary), particularly compatible with the cooling needs for electronic and computer chips and package cooling. The microloop heat pipes (μLHP™) utilize cutting edge microfabrication techniques. The device has no pump or moving parts, and is capable of moving heat at high power densities, using revolutionary coherent porous silicon (CPS) wicks. The CPS wicks minimize packaging thermal mismatch stress and improves strength-to-weight ratio. Also burst-through pressures can be controlled as the diameter of the coherent pores can be controlled on a sub-micron scale. The two phase planar operation provides extremely low specific thermal resistance (20-60 w/cm2). The operation is dependent upon a unique micropatterened CPS wick which contains up to millions per square centimeter of stacked uniform micro-through-capillaries in semiconductor-grade silicon, which serve as the capillary “engine,” as opposed to the stochastic distribution of pores in the typical heat pipe wick. As with all heat pipes, cooling occurs by virtue of the extraction of heat by the latent heat of phase change of the operating fluid into vapor.

摘要： A chromatograph fabricated using microelectromechanical techniques. The chromatograph includes a first layer superimposed over a second layer. At least one micro-channel is etched into the second layer to provide the separation column of the chromatograph. The surfaces of the micro-channel are chemically activated in order to separate the components of a sample flowing through the micro-channel by bonded phase chemistry. A third layer is placed in superimposed relationship with the second layer. At least one pair of electrodes is formed to the third layer with at least a portion of the electrodes internal to the micro-channel of the second layer. The electrodes detect separated components flowing through the micro-channel and identify them by their electrical conductivity. The depth of the micro-channel is greater than the width, thereby minimizing pressure drop across the device and allowing the chromatograph to operate with a high degree of speed, sensitivity and accuracy. Good resolution is obtained with narrow integrated electrodes for sensing the separated components of the sample.

摘要： An implantable auditory system for a human subject includes a microsensor, a processor and a microactuator. The microsensor is implanted in the middle ear to transduce sound waves into electrical signals. The processor is implanted in a hole surgically sculpted in the skull and controls amplification and processing of the electrical signals. The microactuator is micromachined from a single crystal and acts as a parallel plate capacitor, with a diaphragm spaced from the rest of the crystal by an extremely small void therebetween. The microactuator is implanted in the middle ear, and it may extend into the inner ear through a surgically formed fenestration or be mounted to the ossicular chain. Electrical signals conveyed to the microactuator set up electric fields across the narrow void and the diaphragm to produce electrostatic forces that cause the diaphragm to vibrate, thereby directly or indirectly vibrating fluid in the inner ear. Use of electrostatic forces to vibrate inner ear fluid reduces electrical current requirements, resulting in increased battery life.

摘要： A solid state microanemometer is micromachined from a crystal to a shape with four thick external sides that define an outer rectangle, four thin sections that define an inner rectangle and four diagonally directed branches interconnecting the corners of the outer rectangle to the inner rectangle. Four semiconductor resistors located on the four inner sections form a sensing bridge. Each external side has a pair of electrical contacts that are electrically interconnected, via conductive leads that extend along the diagonal branches and partially along the inner sections, to one of the semiconductor resistors. The physically connected semiconductor resistors and external sides form a rugged solid state device, while thermal and electrical isolation of the resistors from each other permits higher operating temperatures and improved fluid flow sensing capability.

摘要： Extra- to intra-corporeal power is provided by a transformer implanted at least partially within a defunctionalized intestinal pouch (or sack), such as an ileal pouch. The transformer includes a continuous loop magnetic core which is implanted within the pouch. The pouch itself includes a passageway permitting the secondary wiring to extend around the and through the magnetic core and through its central opening without entering the pouch providing intracorporeal current. Wire providing the primary windings extend from outside the body in through a stoma into the pouch and surround portions of the magnetic core within the pouch. Because of the use of a generally continuous loop magnetic core of high permeability, there is little or virtually no magnetic flux leakage. A solid circular core of a high permeability material may be used. In an alternate embodiment of the present invention the magnetic core can be divided into two separate portions, one implanted within the pouch and one implanted within the peritoneum adjacent the pouch so that the two core portions combine to form a generally continuous loop magnetic path, separated only by the intestinal wall of the pouch.
