Abstract: A wearable medical monitoring system is provided that includes a support structure worn by a patient, which also housing electrodes and sleep sensors for generating health data. The health data includes ECG data, respiration data, and sleep data, which are used to determine cardiac conditions and sleep disorders. Sleep disorder indexes are formulated with various combinations of sleep factors from the health data of the patient, correlating in time with particular periods of sleep by the patient. In comparing the sleep disorder indexes with respective sleep disorder indicators, potential sleep disorders may be discerned by the monitoring system. Sleep information about the sleep disorders and warnings may be transmitted by the monitoring system to health support entities.

Abstract: A method for improving bonding and sealing in a well, comprising providing a wellbore, providing a pipe, coating an outside surface of the pipe with an adhesive thermoplastic resin, running the coated pipe into the wellbore, and causing the temperature of said wellbore to increase to a temperature greater than a melting temperature of said adhesive thermoplastic resin.

Abstract: Actuator control system and method comprising an electric motor driving a hydraulic pump in fluid delivery communication with a source of hydraulic fluid; a variable speed controller operatively coupled to the motor for driving the pump at variable speeds; an external hydraulic actuator in fluid delivery communication with the pump for receiving pressurized fluid flow from the pump; and a feedback loop operatively coupled from the motor to the controller for providing feedback signals correlative to a pressure of the pressurized fluid flow through the driven pump for driving the external hydraulic actuator in response to the feedback signals for providing electronic velocity and force control of actuation of the external hydraulic actuator. The actuator control system and method can operate on one or many high-pressure hydraulic linear and/or rotary actuators on different pieces of hydraulically driven equipment and with different velocity requirements actuating in different directions.

Abstract: A system and method for controlling the temperature of a process tool uses the vaporizable characteristic of a refrigerant that is provided in direct heat exchange relation with the process tool. Pressurized refrigerant is provided as both condensed liquid and in gaseous state. The condensed liquid is expanded to a vaporous mix, and the gaseous refrigerant is added to reach a target temperature determined by its pressure. Temperature corrections can thus be made very rapidly by gas pressure adjustments. The process tool and the operating parameters will usually require that the returning refrigerant be conditioned and processed for compatibility with the compressor and other units, so that cycling can be continuous regardless of thermal demands and changes.

Abstract: A barrier system for a subsurface treatment area is described. The barrier system includes a first barrier formed around at least a portion of the subsurface treatment area. The first barrier is configured to inhibit fluid from exiting or entering the subsurface treatment area. A second barrier is formed around at least a portion of the first barrier. A separation space exists between the first barrier and the second barrier.

Abstract: Improvements in systems and methods which employ a two-phase fluid, such as a refrigerant, as a saturable fluid in direct heat transfer relation to a thermal load, are realized by extraction of vapor from the saturated fluid before heat exchange. Moreover, automatic changing of the paths under command of a controller enables charges to be effected between different modes at higher rates than in other systems by employing the variety of modes available in the direct transfer system.

Abstract: Disclosed is a composition comprising a chemical formulation useful for creating geosynthetic composites in-situ, which includes a reactive ester having at least one carbon-carbon double bond, preferably a vinyl ester of a C9 to C11 versatic acid or vinyl ester of a long chain fatty acid, or a combination thereof, at least one unsaturated thermoplastic elastomer soluble in the reactive ester; at least one di- or tri-functional acrylate or methacrylate monomer. The formulation may further include a non-aqueous drilling fluid.

Abstract: In many processes used in fabricating semiconductors the wafer is seated on the top surface of a pedestal and heated in a high energy process step, such as plasma etching. The pedestal, chuck or platen may be cooling but the wafer gradually heats until the process can no longer continue. Where large, e.g. 300 mm diameter, wafers are being processed the temperature level across the wafer is difficult to maintain substantially constant. In this system and method the lateral temperature distribution is equalized by a heat sink structure in a chamber immediately under the wafer support on top of the pedestal. A number of spatially distributed wicking posts extend downwardly from a layer of wicking material across the top of the chamber, into a pool of a vaporizable liquid. At hot spots, vaporized liquid is generated and transported to adjacent condensation posts extending up from the liquid. The system thus passively extracts heat to equalize temperatures while recirculating liquid and assuring adequate supply.

Abstract: Disclosed is a composition comprising a chemical formulation useful for creating geosynthetic composites in-situ that includes a melamine-formaldehyde resin in a non-aqueous drilling fluid.

Abstract: Systems and methods for heat exchange in accordance with the invention define adequately long-interchange distances for two fluids by wrapping a tube containing a first fluid about the wall of an inner cylindrical tank, within a gap formed with a second concentric tank. A second fluid is transmitted in the space defined between the turns of the tube and the two walls, providing effective short length thermal interchange through the tube walls. The tube is in the line contact with both tank walls and the fluids can flow rapidly over an adequately long length, so that high efficiency is provided in a low cost system.

Abstract: Disclosed is a method of reducing lost circulation, sealing lost circulation zones, and stabilizing weak formations, using copolymers of ethylene acrylic or ethylene methacrylic acid, or the single valence ionomers thereof, characterized as low density, solid at ambient temperature, reactive in selected temperature ranges, ductile, and able to adhere to rock and to each other to form ionomers in situ, wherein said copolymers are optionally used in combination with other solid agents, and wherein the treatment of said zones can be further enhanced by particle sizing and by blending into the treatment mixture multivalent alkaline earth and/or transition metals to provide optimum properties for the resulting ionomers given formation temperatures, conditions, and compositions.

Abstract: Disclosed is a method for strengthening a wellbore with an exposed geological formation, the method including: determining or estimating material properties of the exposed geological formation; determining changes necessary in material properties of the exposed geologic formation to achieve desired improvements in property of the exposed geologic formation; and treating the geological formation to improve material property values by injecting a formulation that hardens in-situ to form a geosynthetic composite. In another aspect, the present invention relates to an apparatus for utilizing the described method with minimal handling of chemicals which is an automated in-line chemical metering and pumping apparatus that requires no large mixing tank.
