An apparatus and method for calculating the selectivity of a range query for multidimensional data using a multidimensional histogram are provided. A data space may be partitioned into one or more sub-spaces based on a sum of skew values of the one or more sub-spaces, a space-partitioning tree may be generated for the data space, and a multidimensional histogram may be generated for the data space based on the space-partitioning tree. A range query for multidimensional data may be processed based on the multidimensional histogram.

A cardiac rhythm management device for obtaining transthoracic impedance. The device comprises a sensor for obtaining a signal indicative of an action of a heart, an impedance measurement circuit adapted to measure transthoracic impedance and a processor for utilizing the signal indicative of the action of the heart to sample the transthoracic impedance at sampling intervals commenced by fiducial markers in the signal indicative of the action of the heart, where the sampling of the impedance signal removes the component of a stroke volume of the heart from the signal and thereby provides lung ventilation information.

An electric motor includes a stator, a rotor disposed to be rotatable with respect to the stator, and a cooling unit including a cooling fluid and disposed between the stator and the inverter device to cool the stator and the inverter device. Weight can be reduced, and thus, power consumption of a battery can be reduced and a traveling distance of the vehicle can be increased.
摘要:
An electric motor includes a case, a stator disposed in an interior of the case, a rotor including a shaft disposed to be rotatable with respect to the stator, and an oil circulator to contact with oil that is accommodated or stored at the interior of the case, the oil circulator may disperse at least a portion of the oil when the rotor rotates with respect to the stator. Accordingly, outputs can be improved by restraining an increase in the temperature of components.

A technique for identifying a vein in a patient is disclosed. The technique involves the application of a thermochromic ink to a venous area on the skin of a patient (e.g., human or animal). The thermochromic ink comprises thermosensitive color-changing microcapsules that contain a proton-accepting chromogen and a desensitizer. The desensitizer possesses a melting point above which the chromogen is capable of becoming protonated, thereby resulting in a color change. Thereafter, the venous area is observed for the color change.

A method and system for verifying capture in the heart involves the use of pacing artifact templates. One or more pacing artifact templates characterizing a post pace artifact signal associated with a particular pace voltage or range of voltages are provided. A pacing artifact template is canceled from a cardiac signal sensed following a pacing pulse. Capture is detected by comparing the pacing artifact canceled cardiac signal to an evoked response reference. Fusion/pseudofusion detection involves determining a correlation between a captured response template and a sensed cardiac signal.
摘要:
To provide a microwave plasma-treating apparatus which is capable of generating plasma having a high degree of uniformity of density and a high density for executing large-quantity and high-speed processing, capable of generating plasma of a large area, and capable of preventing dielectric windows from being thermally broken despite the apparatus being operated with large electric power for extended periods of time. The microwave plasma-treating apparatus includes a waveguide arranged to feed microwave electric power, a plurality of microwave coupling holes formed in the waveguide in the axial direction thereof, a dielectric member of a piece of plate capable of transmitting microwaves arranged in the waveguide in the axial direction thereof under the microwave coupling holes, a gap formed between the plurality of microwave coupling holes and the dielectric member, and a cooling member for cooling the dielectric member. Desirably, the microwave coupling holes have an annular shape.

An odor control substrate that is applied with an activated carbon ink is provided. The activated carbon ink is applied in a pattern that covers from about 25% to about 95% of the surface area of the substrate. Although not covering the entire surface, the present inventors have discovered that the activated carbon ink is still capable of providing good odor reduction qualities to the substrate. To further enhance the aesthetic appeal of the odor control substrate to a consumer, one or more colored inks may also be applied the substrate in a pattern that may or may not overlap with the activated carbon ink pattern. The colored ink(s) may contrast well with the activated carbon ink to provide an overall design that is more aesthetically than otherwise would be provided by a uniform coating of activated carbon ink.

This invention concerns extrudates having high surface area materials and at least one metal ion adsorbed onto the high surface area material. The extrudates may be breathable films, multilayer laminates and pultruded articles. The extrudates may be made into storage and packaging material to reduce odor and retard the ripening of fruit. The extrudates, if in the form of a breathable film or multilayer laminate may be used as outer cover material for personal care products like diapers, adult incontinence products, training pants and the like. The high surface area particle-containing extrudate may be made by adding modified nanoparticles to a filler before the filler is treated with a fatty acid. Alternatively, a filler previously treated with a fatty acid may be modified by subjecting the filler to sonic energy in the presence of an aqueous solution of metal ions and nanoparticles.

A planar substrate has a moisture activated shrinking filament applied thereon. When wetted, the shrinking filament shrinks and causes the planar substrate to gather and pucker. The planar substrate with the filament thereon may be compressed into a compact shape when in a dry state.
