    摘要： A hydronic panel and system for heating and/or cooling a room is disclosed. The hydronic panel includes a plurality of contiguous channels. A first chamber is located at a first end, preferably the upper end, of the panel and includes an inlet and communicates with a first subset of the channels. A second chamber is located at an opposite end of the panel and communicates with the first subset and also with a second subset of the channels. A third chamber is located at the first end of the panel, the third chamber communicates with the second subset of the channels and includes an outlet. In this configuration, heated or cooled water flows from the inlet into the first chamber, through the first subset of the channels, to the second chamber, through the second subset of the channels, into the third chamber and out the outlet. Consequently, the heated or cooled water can heat or cool the space. In addition to at least one hydronic panel, the system includes a source of heated and/or cooled water under sufficient pressure to cause the water to flow through the panel. The system also includes a controller to control one or both of the temperature of the water and the flow rate of the water through the panel.

    摘要： We disclose a cordless window blind that includes at least one electromagnet within each slat. The slats may be inserted into orifices within rotatable slat mounting members on a vertical guide rail assembly. The orifices may house electrical connections which connect the electromagnets to at least one battery. The electromagnets may have the same polarity such that the electromagnet of one slat attracts the electromagnet of an adjacent slat. The magnetic attraction may move one slat toward the other slat causing the slats to move vertically along the guide rail assembly and either raise or lower the blinds. Alternatively, electromagnets on only one of two longitudinal edges of the slats may be actuated and attract a metal member on an adjacent slat. The magnetic attraction may cause the slats to tilt and rotate within the slat mounting members thus closing the blinds.

    摘要： A gear-shifting device is disclosed. The device comprises a first motor having a first rotor. The first rotor turns clockwise and counter-clockwise, creating a wobbling action. The device further comprises a compound planetary transmission, comprising a transmission ring attached to a ring gear. The compound planetary transmission receives power from the first rotor. The device further comprises a second motor having a second rotor. The second rotor turns clockwise and counter-clockwise. The device further comprises a shift assembly, comprising a drum, a cap, and a pinion gear. The pinion gear receives power from the second rotor. The drum locks with the pinion gear such that the drum rotates with the pinion gear. The transmission ring is attached to the drum, such that the transmission ring moves laterally as the drum rotates. The ring gear locks and unlocks with the cap as the drum rotates. The wobbling action enables the locking.

    摘要： An out-of-autoclave compression molding system is disclosed herein. The system includes a mold, a vacuum bag, a vacuum valve, a pressure plate, and a pressure valve. The mold includes a concave feature and a flange. The vacuum bag covers at least the concave feature. The pressure plate is positioned outside the vacuum bag clamped to the flange and on the mold to form a pressure cavity between the vacuum bag and the plate. An out-of-autoclave compression molding process is also described. The process includes pressing a composite material and thermoset resin into a mold having a flange; surrounding the mold, composite material, and resin with a vacuum bag; sealing and evacuating the vacuum bag; clamping a pressure plate to the flange; and pressurizing the cavity.

    摘要： We disclose a microfabricated device for both extracting and preconcentrating samples for gas chromatography analysis. The device includes a conduit with at least two sections and multiple ports which may be connected to multiple gas chromatography columns. The inner surface of the conduit may be coated with multiple sorbents which bind volatile analytes with different affinities. The sections of the conduit may be divided by a thermal barrier which inhibits heat transfer between sections. Consequently, each section may be independently heated to encourage desorption of volatile analytes. The disclosed device separates and concentrates volatile analytes into different pools according to their chemical and physical properties before they enter a gas chromatography column that is optimized for that pool. The device reduces the amount of heat and time needed to perform gas chromatography analysis as well as avoids the need for purified gas sources typically used for the moving phase.
