Abstract: A multi-color cavity ringdown based spectrometer system is housed in a light tight enclosure to detect the presence of trace quantities of gas phase molecules emanating from a subject, explosives, drugs, or hazardous materials. A method is also disclosed for simultaneous real time detection of gas phase molecules emanating from explosives, drugs, hazardous materials, a subject's breath skin or bodily fluid.

Abstract: Winged costume attachments provide for the quick and easy donning and removal of costume wings, as worn for various costume parties or gatherings, stage plays, etc. The attachments comprise left and right shoulder and wrist straps, with each strap preferably formed of an elastic material covered with a protective fabric sleeve. Reinforcements are provided at each wingtip for secure attachment of the wrist straps, and an additional central reinforcement panel is provided for secure attachment of the shoulder straps. The central reinforcement panel may comprise a specific panel provided only for reinforcement, or may comprise a portion of an additional panel extending from the wing panels to form a tail or other component. The present attachment strap configuration results in the neck and chest areas of the wearer remaining clear of any attachment straps, thereby providing a safer costume which is easily donned and removed by small children without assistance.
