Abstract: A computer processor driven system and method capable of identifying and constructing representations of hazardous areas. The hazardous area classification system has one or more processors, and a computer readable medium containing instructions that, when executed, cause the one or more processors to perform the steps of determining a position of a hazardous area for a predetermined location using a calculation based on a plurality of parameters, and generating a representation of the hazardous area.

Abstract: Disclosed are methods for identifying double-stranded nucleic acid protein binding sites and double-stranded nucleic acid binding proteins. The method can include contacting a sample with at least one partially double-stranded nucleic acid probe under conditions that permit binding of double-stranded binding proteins and partially double-stranded nucleic acid probes. In particular examples, the partially double-stranded nucleic acid probes include a first portion of single-stranded nucleic acid at least about 15 nucleotides in length with a unique index sequence and a second portion of double-stranded nucleic acid greater than about 8 base pairs in length with a potential binding site for a double-stranded nucleic acid binding protein. The protein bound partially double-stranded nucleic acid probe can then be isolated and detected by hybridization to a nucleic acid indexing probe. Also disclosed are kits and devices for carrying out the methods.

Abstract: An improved hand-worn signaling device is disclosed that comprises at least one light-emitting assembly on the palmar side of the hand and at least one light-emitting assembly on the dorsal side of the hand; in one embodiment of the invention, the palmar light-emitting assembly is red and the dorsal light-emitting assembly is green. One embodiment of the device also comprises a controller that detects hand motions by the user and activates the appropriate light-emitting assembly in response. In another embodiment, the controller detects the angle of the user's wrist or knuckles, and activates the appropriate light-emitting assembly depending on the angle of the user's joints. In another embodiment, the controller detects the spatial orientation of the user's hand, and activates the appropriate light-emitting assembly depending on whether the user's hand is positioned vertically with the fingers pointing straight up (the “stop” position) or in any other orientation.

Abstract: A heating, ventilating, and air-conditioning system utilizes a pressurized fluid to generate heat and drive the components of the system. As the pressurized fluids turns the components heat is generated. The heat in the fluid can be transferred to air via a heat exchanger and/or a radiant heater. A generator is turned by the pressurized fluid and generates electricity for an auxiliary fluid heater and operation of the system and/or backfed to a battery or power grid.
