A portable drug testing device for handheldly collecting a sample from exhaled breath of a subject for further sensor based analysis. The portable drug testing device comprising a housing comprising at least one inlet and at least one outlet for the exhaled breath to exit through, and a sampling membrane arranged in the housing. a tubular element having a mouthpiece section for the subject to exhale into, and a selective trap section in fluid communication with the mouthpiece and the inlet of the housing having a non-straight gas flow path for letting aerosols pass through the tubular element. The sampling membrane is arranged to collect the aerosols from the exhaled breath. The portable drug testing device further comprises a volume measure unit for determining that a pre-defined volume of the exhaled breath has passed through the sampling membrane.

To improve the production yield rate of a synthesis corundum cell superior in translucency, chemical resistance or an optical component comprising calcium fluoride. On the other end side of synthetic corundum piece, spacer intervenes between the surfaces which will be bonded. The spacer is crushed flat by pressure force which effects the other end side of synthetic corundum piece in the case of heat-treatment after the temporary bonding. Thereby, the spacer does not disturb the synthetic optical contacting or chemical pressurized fusion bonding state of corundum piece.

A composite housing and a method of assembling a composite housing for a scanning assembly. A body of the housing defines an opening of a first perimeter. A polymethylpentene scanning plate is provided which has lip with a marginally larger perimeter than the first perimeter. During assembly of the composite housing, at least a part of scanning plate is thermally contracted to allow it to be positioned within the opening such that the peripheral side surface of the scanning surface faces the edge of the body. When the scanning plate returns to ambient temperature and expands at least a portion of the side surface of the scanning plate engages the edge of the body.

A fan blade and method of covering a fan blade root portion for a gas turbine engine are disclosed. The fan blade includes an airfoil having a leading edge end and a trailing edge end, a root portion having a first side surface extending from the leading edge end to the trailing edge end and a second side surface at an opposite side of the first side surface and extending from the leading edge end to the trailing edge end, and a covering disposed against the first side surface and the second side surface, wherein the covering is positioned against the root portion as a single member.

A method and apparatus for assembling a high purity liquid distribution system is described. A distal end portion of the tube is heated then pushed over a sleeve so that the distal end portion can have a shrink seal fit over the sleeve to mitigate accidental or inadvertent pull out of the tube from a fitting. Other benefits are also achieved such as minimal flow restriction of the liquid flowing through the joint and the tube.

A workpiece unit containing a workpiece body is provided. A method for producing the workpiece unit is also provided. The workpiece body contains a plurality of sections. The sections divide the processing surface of the workpiece body. The size of each section of the workpiece body can be adjusted or selected according to the demand so that it is possible to increase utilization efficiency of the workpiece body.

A medical device-includes a scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the balloon by a process that includes inflating the delivery balloon during a diameter reduction to improve scaffold retention and maintaining an inflated balloon during the diameter reduction and prior and subsequent dwell periods.
