Abstract: A tool to assist with hand-tying of knots in balloons, cords, and the like. The tool has a head consisting of a hollow tube with an opening running the length of the tube. The tube is typically tapered with a flange toward the larger end, and the opening is incorporated at an angle nonparallel to the center line of the tube, forming a notch feature that passively retains material on the head until removed by the user. The head is connected to a handle with two or more functionally independent finger loops. The tool may be retained on the hand without unduly impeding dexterity and provides for greater control of the tool when in use.

Abstract: The invention provides for a multiple analyte detector that is capable of detecting and identifying explosive, chemical or biological substances having multiple analytes with a single system having multiple reporters. The reporters include fluorescent polymers, conducting polymers, metal oxide elements, electrochemical cells, etc. The reporters may be combinations of other reporters that are optimized for broadband detection.

Abstract: The current invention provides a detector and method suitable for sensing vapor-phase hydrogen peroxide. The detector utilizes a chemiluminescent material comprising a peroxide reactive compound, a dye and a solvent. Upon reaction with hydrogen peroxide, the chemiluminescent material will generate detectible light.
