Abstract: A fluid heat exchange system with a fluid flow circuit having a heat exchange fluid flow loop, a heat absorption component (as in a domestic hot water tank inclusive of small commercial use tanks as in tanks of 20 to 120 gallons), a heat exchanger and preferably also a pump. A controlled and automated fuel supply source based heater (as in a pellet stove) is in heat passage communication with the said heat exchanger. A control unit triggers activation of the pump upon fluid in the heat absorption component reaching or dropping below a preset temperature, and the fluid flow circuit is arranged such that, during times of non-activation of the pump, fluid is free to flow in a unidirectional flow within the fluid circuit based on thermodynamic temperature differentials alone. A retrofitting of a domestic hot water tank is also featured preferably making use of preexisting drain and safety vent porting for in-feed and out-feed porting in the exchange loop side.

Abstract: A catheter is designed with a virtual electrode structure for creating a linear lesion. The catheter includes a sensor array that measures temperatures of adjacent tissue along the length of the virtual electrode section. The sensors in the sensor array include a conductive material that is substantially coated with an electrically and thermally insulating material. An aperture is formed in the insulating coating to expose an area of the conductive material. Leads are coupled with each sensor and are connected at their opposite, proximal ends with a discrimination circuit. The circuit processes the signals induced in the sensors to output a single temperature measurement, for example, the highest temperature, the lowest temperature, or the average temperature. The sensors also measure cardiac electrical activity and the leads are further connected to an electrocardiograph monitor to determine the efficacy of treatment.

Abstract: Certain ?-amino acids that bind to the alpha-2-delta (?2?) subunit of a calcium channel are disclosed. These compounds and their pharmaceutically acceptable salts are useful in the treatment of a variety of psychiatric, pain and other disorders. Also disclosed are methods of making the ?-amino acids.

Abstract: Methods of preparing compounds of Formula I are provided.

Abstract: The present invention is a method for calculating blood pressure of an artery having a pulse. The method includes applying a varying pressure to the artery. Pressure waveforms are sensed to produce pressure waveform data. Waveform parameters are derived from the sensed pressure waveform data. Blood pressure is then determined using the derived parameters.

Abstract: Methods of preparing compounds of Formula I are provided.

Abstract: Methods and materials for preparing 4-substituted-2-buten-4-olides are disclosed. The method includes reacting a mucohalic acid with a silyl enol ether or a ketene silyl acetal in the presence of a Lewis acid.

Abstract: A novel wide area-networked system and method allows users of a web site-based network to negotiate, modify and interpret the performance of complex agreements between network users via the web site. A web site host computer system provides contract templates governing the general type of contractual relations contemplated by the contractual parties, and allows direct negotiation between the users via the web site. Complex terms are allowable, including those that vary the price of goods and services over the course of a contract, such as volume discounts, rebates, and other incentives. The host computer system also serves to locate buyers and sellers with similar contractual interests and provides a history of previous network contracts to give potential buyers and sellers an idea of probable contractual terms when dealing with a prospective contractual party.

Abstract: A blood pressure measurement device with a sensor locator for placing a non-invasive blood pressure measurement device over an underlying artery, the sensor locator having a plurality of extending fingers spaced from each other coupled to the non-invasive blood pressure measurement device.
