Abstract: An apparatus for training canines to detect complex hazardous substances from an odor mixture developed from at least two separated material components having at least two separated odors respectively. The training apparatus has a chamber base unit having at least two vial wells configured to hold separate containers of the material components and a chamber top unit having a first side facing the chamber base and a second side opposite the first side. The first side of the chamber top unit and the chamber base unit define a primary vapor mixing chamber in fluid communication with the vial wells. A mechanical seal between the chamber top and the chamber base seals the primary vapor mixing chamber. A passageway extends through the chamber top unit connecting the primary vapor mixing chamber to the second side of the chamber top unit.

Abstract: Disclosed is an apparatus having: a pressure chamber and a gas-producing microorganism within the chamber. The pressure chamber is capable of maintaining a gas pressure of at least 0.5 psi above atmospheric pressure.

Abstract: A method and system for generating vapors of liquid solutions where a pneumatically modulated liquid delivery system maintains a defined flow rate for a liquid solution. The pneumatically modulated liquid delivery system includes a flow meter configured to measure a flow rate for the liquid solution flowing from a pressure vessel; a microcontroller configured to determine a pressure necessary to achieve the defined flow rate; and an electronic pressure control unit configured to adjust the pressure inside the pressure vessel. The system includes a nebulizer coupled to the pneumatically modulated liquid delivery system configured to receive the liquid solution from the pneumatically modulated liquid delivery system at the defined flow rate and configured to generate an aerosol of the liquid solution. A heat tube can vaporize the aerosol generated by the nebulizer.

Abstract: Provided is a method and apparatus for attaching a fluid cell to a planar substrate. The planar substrate may have on it sensors or devices for detecting components within the fluid, and/or be treated to selectively bind or react with components within the fluid. Substrates might include solid-state IC integrated circuit sensor microchips, glass slides, genomic and proteomic arrays, and or other suitable substrates that can make conformal contact with the fluid cell. The fluid cell can be mounted directly on top of the substrate to easily create a fluidic system in a wide variety of implementations. The assembly does not require modification of the substrate; all the fluidic connections are inherent in the apparatus. The present device can be made using low-cost materials and simple methods.

Abstract: The present invention relates to a device for interconnecting multiple fluid conduits in a microfluidic environment. The device is typically used to make a low-pressure fluidic connector system for microfluidic applications. A male connector component containing an array of conical nozzles having through holes is connected to fluidic tubing. A female connector component supports an elastomer membrane having an array of receptacles complementary to the nozzles. Through holes through the female connector and membrane are also connected to fluidic tubing. The conical nozzles are aligned with membrane receptacles and a connecting mechanism evenly distributes a compressive force between the male and female components to establish a fluid-tight seal between the nozzles and the membrane.
