The low-temperature radiating section is connected to a cryo-pump, while the high-temperature radiating section comprises an infrared ray lamp or a far infrared ray lamp. The present invention is applicable to medical treatment, physical therapy, sterilization of cosmetics or pharmaceuticals, or to tests of critical temperature for survival of cells.
Abstract: An in-line water heater utilizing electrically conductive polymer structures for electrodes. The area of electrodes that confront one another can be varied, and thereby the temperature to which the water is heated can be variably adjusted. The heat is not generated by the electrodes, but instead by the resistance of the water to the electrical current flowing between them. While the electrodes can be moved relative to one another, preferably they will be fixed, and an non-electrically conductive current gating plate can adjustably be placed between them to variably adjust the amount of confronting areas. A field obstructor can be provided at the inlet and outlet of the heater housing to prevent the exit of electrical current from the heater electrodes, and also non-conductive grounding screens in place for secondary safety.

A proximal end of the scope is connected to an image-signal processing unit, in which the image-pixel signals are processed to produce a video signal. A light source device is provided in the processing unit. An optical light guide extends through the scope. When the connection is established between the scope and the processing unit, the light guide is optically connected to the light source device. The light source device includes a white light lamp, and an ultraviolet lamp, and a mirror for selectively introducing either the white light or the ultraviolet light into the light guide.
Abstract: A hydraulic transmission pump assembly adapted to provide fluid under pressure to predetermined components in a transmission including a one-way clutch assembly operatively coupled to the pump and an electric motor operatively coupled to the one-way clutch. The one-way clutch is operatively connected to an engine to provide motive power the pump and the electric motor at engine speeds above a predetermined level thereby providing fluid under pressure to the transmission and driving the electric motor to generate electricity. The electric motor is operable to drive the pump at engine speeds below the predetermined level to provide fluid under pressure to the transmission during this operating condition.
Abstract: In an embodiment, a method for reconstructing a corrected Magnetic Resonance (MR) image from acquired MR data subjected to gradient field non-linearity comprises producing a data set that corresponds to linear gradient fields responsive to the acquired MR data and reconstructing the data set into the corrected MR image. Thus, correction for distortion is a k-space based correction method.
Abstract: A technique is described for timing hardware or software events for use in an implantable medical device capable of performing many concurrent processes. The technique exploits a first timer for timing events using a timing interval of one millisecond and a second timer or clock signal for timing events using a timing interval of two seconds. A receive unit receives timer requests from the many concurrent processes with each timer request specifying a time delay before an interrupt or other timer completion signal is required. A control unit uses either the first timer or the second timer to time the request based upon the time delay and the respective timing intervals. An interrupt or other timer completion signal is issued to the requesting device following the specified time delay as timed by the selected timer.

Abstract: The automatically controlled pump includes a battery-powered motor with a housing, a pump in a housing with input and output ports. A switch turns ON and OFF the motor due to fluid pressure at the output. Sometimes, the pump housing is below the motor housing and below the battery housing. The input port is beneath the impeller and the output port. A version also includes a manual ON and OFF switch actuated by an operator and a check valve limiting upstream flow of the pressurized fluid. The fluid pressure sensitive switch is mounted downstream of the check valve. An irrigation surgical kit includes the automatically controlled pump, a spike for a fluid source bag, fluid lines and an operator controlled valve unit disposed at or near the surgical site. The method monitors fluid pressure at or near the pump's output and turns ON and OFF the motor.

Abstract: A controller controls the temperature of a hot plate and the degree of vacuum in a tightly closed space to a temperature and a pressure at levels at which a thinner contained in a resist applied to a wafer volatilizes and an acid generator, a quencher, and a polymer chain protecting group practically remain in the resist, for example, during heat processing. More specifically, the controller controls the temperature of the hot plate and the degree of vacuum in the tightly closed space to bring the temperature of the hot plate to about 40° C., and the degree of vacuum in the tightly closed space to approximately 5 Torr. Thereby, the heat processing can be performed for the wafer so that the acid generator is uniformly dispersed in the resist, or the quencher is uniformly formed on the front face of the resist without breakage of the polymer chain protecting group.
Abstract: The invention concerns a sealing- and cooling system for a submersible machine, such as a pump or a mixer.
The device comprises an easily replaceable (4) containing mechanical face seals with an intermediate room for a barrier liquid where a circulation pump (10) is arranged for circulation of said liquid along the seals as well as around the driving unit (1) of the machine. During circulation, the liquid passes a first narrow gap (6) around the driving unit where heat is absorbed and a second narrow gap (7) where heat is discharged.
Abstract: A device is described that can be easily used to warn an asthmatic or allergen reacting patient of irritant levels which may trigger an asthma or allergy attack for that person. The device continually monitors and records irritants in the air, and when the concentration exceeds the predefined level the device generates an alarm signal for the user. The recorded data can be downloaded to a computer, and this information can be used by the patient and the physician to identify irritants, guide treatment, and determine threshold levels.

Abstract: A method for monitoring a biological tissue includes illuminating the tissue, including a fluorophore, with a wavelength of light, the wavelength selected for exciting the fluorophore, determining a fluorescent emission of the fluorophore, the emission indicating the presence of the fluorophore, and correlating an emission of the fluorophore to an extent and degree of damage to the tissue. Damage to the tissue includes a breakdown of the fluorophore, resulting in a reduced level of emission. The fluorophore can include one of collagen and elastin. The fluorophore can include tryptophan, nicotinamide adenine dinucleotide, flavin and porphyrin. Correlating the emission of the fluorophore to the extent and degree of damage further includes processing a correlation of the emission over time, controlling the power of a laser welder based on the processed correlation, and preventing overheating of the tissue by the laser welder.
