  • Patent number: 10283337
    Abstract: Despite the desire to measure the composition and concentration of the microparticles included in a gaseous body sample serving as the measurement target, there is a problem that measurement cannot be performed accurately due to the effect of substances other than the gaseous body sample adsorbing to a trapping body of the analyzing apparatus that traps the microparticles, for example. Therefore, provided is a microparticle composition analyzing apparatus that analyzes composition of microparticles contained in a gaseous body sample, comprising a gas analyzer and a control section that sequentially introduces into the gas analyzer a comparative gas and a sample gas caused by the microparticles generated by irradiating the gaseous body sample with a laser.

  • Patent number: 10006651
    Abstract: A personal cooling device utilizes a portable container for retaining a liquid that is wicked into a wicking, material and a fan to draw air into the container through a plurality of apertures to produce a flow of cool air. Air drawn into the container through the apertures flows through the wicking material and is cooled by evaporative cooling. The air then flows out of the top of the container and through the air moving device. A funnel is configured around the outer perimeter of the container to capture any liquid that spills out of the apertures and direct it back into the container. A battery pack may be coupled to the air moving device by an extension cable for storing the battery pack in a more convenient location, such as on a belt.

  • Patent number: 7712325
    Abstract: A modular electronic cooling system with moving parts, composed of a base unit and individual modules inserted into this base unit in respect to the expected upper limit of the heat load may utilize thermoelectric power generation and the heat load itself to allow for operation independent of any external power source. By the same mechanism the cooling system scales within a range automatically reacting to and dissipating a dynamic heat load via forced convection, and doing so passively, without the need for specific programming. This cooling system uses porous material or multi-layered mesh parts, thermoelectric components, a modular assembly system and independent enclosure parts for described porous material or multi-layered mesh, an electronics control system that may be passively activated, and a motor assembly. Altogether the system provides maximum efficiency in terms of form factor.

  • Patent number: 7708256
    Abstract: A fragrance disperser in one form includes a single fan that passes air over a wicked single or double fragrance. A second form has the fan reversible to provide two different airstreams that evaporate respective different fragrances one after the other. Where two fragrances are provided, the evaporation may be by respective electrical heaters. A fragrance source may be formed by two sheets joined together to form two chambers each receiving a respective wick and having respective exposed wick portions. The source may incorporate a source of electrical power. An alternative source has a reservoir for fragrance and a wick located in an air passage forming part of the source so that an air flow is guided through the passage past the wick to evaporate fragrance. Where two fragrances are provided, the fragrance sources may be located side-by-side and matching fragrances may have, for example, matching indicia on the sources so that the match can be easily determined visually.

  • Patent number: 7624971
    Abstract: A device includes a housing having a hollow center and a case having a hollow fiber membrane. The case is at least partially located inside the hollow center of the housing. A first gas flow flows to the hollow center through an introducing pipe and exits the housing via a discharging pipe. A second gas flow flows through the hollow fiber membrane in the case. The first gas flow enters the case through an inflow opening in the case from a gap between a wall of the housing and the case and exits the case through a discharging opening in the case to the gap between the wall of the housing and the case. The introducing pipe is located adjacent to a dividing wall. The device provides a humidifying property by transferring moisture from the first gas flow to the second gas flow or vice versa.

  • Patent number: 7494114
    Abstract: A system and method for producing a controlled blend of two or more fluids. Thermally-induced permeation through a permeable tube is used to mix a first fluid from outside the tube with a second fluid flowing through the tube. Mixture ratios may be controlled by adjusting the temperature of the first fluid or by adjusting the pressure drop through the permeable tube. The combination of a back pressure control valve and a differential regulator is used to control the output pressure of the blended fluid. The combination of the back pressure control valve and differential regulator provides superior flow control of the second dry gas. A valve manifold system may be used to mix multiple fluids, and to adjust the volume of blended fluid produced, and to further modify the mixture ratio.

  • Patent number: 7494532
    Abstract: A carrier is used to carry a liquid, and a high voltage is applied between a discharge end of the carrier and an opposed electrode to emit ionized liquid particles. The carrier has a liquid collecting end opposite to the discharge end to feed the steam of the liquid from a steam generator, condensing the liquid therearound, and feeding the condensed liquid to the discharge end. Accordingly, even when the liquid contains cations such as those of Ca and Mg, the steam of the liquid can extremely reduce the content of these impurities, avoiding the precipitation of the impurities at the discharge end of the carrier to assure stable electrostatic atomization.
