Embodiments described herein related to devices and methods for the collection and/or determination of analytes, such as illicit substances including military explosives, explosives, and precursors thereof. In some cases, the device may be a disposable device that incorporates highly efficient sample collection in combination with microfluidic-based chemical analysis resulting in the rapid detection and identification of unknown materials. In some cases, multiple colorimetric detection chemistries may be employed, and the resulting 'barcode' of color changes can be used to positively identify the presence and/or identity of the analyte.

Methods and apparatuses for calculating an optimal revenue total yield for both sleeping and function space in a hospitality establishment for a set of demand that includes both group and transient demands. In a preferred embodiment of the invention, the revenue optimization problem is characterized as a mixed-integer linear programming (MILP) problem and solved using MILP techniques. Preferably, a small value is assigned to the 'cost' of a room upgrade and the cost of room upgrades are included in the revenue function to be optimized. In some embodiments of the invention, the actual revenue yield is compared to the optimum revenue yield.

A tool for cutting tubing, light pipe, and other similar cylindrical materials includes a circular cutting wheel or blade and opposite guide rollers in a spring loaded hand clamp frame. The frame spring urges the two opposed handles apart, thereby urging the two opposed jaws together, and thereby precluding any need for additional adjustment of cutting pressure during the cutting operation. The tool may be applied with only one hand to the material to be cut, and easily rotated about the material with only one hand, as no further adjustment of blade depth or cutting pressure is required. The relationship between the cutting blade and guide rollers is constant, with the center of the cutting blade always positioned linearly along the perpendicular bisector of the line between the two guide rollers, even though the opposed jaws move arcuately relative to one another. The guide rollers are affixed within one jaw, with the cutting blade portion slidably positioned relative to the guide rollers. The cutting blade portion is not positively connected to the opposite jaw, in order to allow the linear relationship of the guide rollers and cutting blade, and arcuate relationship of the two jaws of the tool. The guide roller and cutting blade relationship allows material of any practicable diameter to be cut by the present tool, without an asymmetrical force being placed on the material and causing it to be expelled from the jaws.

Tubing cutter

A tool for cutting tubing or light pipe provides conventional cutting rollers and a blade in combination with a spring loaded, open jaw clamp. The open jaw permits the tool to be passed over the side of the material to be cut, while the spring compressive force automatically urges the cutting blade into the material being cut as the tool is rotated around the material in the manner of conventional tubing and pipe cutters. Thus, the need to continually adjust the cutting blade as the cut deepens is eliminated. Two basic embodiments are disclosed, one comprising a handled clamp type tool with or without foldable or extendible handles, and the other comprising a C clamp type tool. The spring loading arrangement of the cutting blade is common to both. Various versions and improvements are also disclosed, including mechanisms providing for parallel actuation of the cutting assembly, proper spacing of the cutting rollers, and maintaining the proper angular relationship between the rollers and the cutting blade.
