Abstract: A system for detecting and extinguishing fires occurring within a predetermined observation area in response to commands received from a monitoring center. The system includes a source of fire retardant liquid and a monitor for selectively directing liquid to the observation area. A valve is disposed in fluid communication between the source and the monitor and is selectively movable between a closed position wherein liquid is prevented from flowing through the valve, and an open position wherein liquid can flow through the valve. An infrared camera generates a signal in response to temperature changes occurring in the observation area. A network switch is provided for communicating with the monitoring center. A control unit in communication with the valve, the camera, and the network switch relays the signal to the monitoring center and moves the valve between the positions in response to commands received from the monitoring center.

Abstract: A gas supply system primarily designed for use with fire sprinkler systems which includes a control system which uses flow demand to automatically determine the mode of operation and switch between providing air and nitrogen. The gas supply system can operate either in standard nitrogen generation mode where nitrogen is supplied to the reservoir tank and/or sprinkler system or in a bypass mode, where sufficient pressure is only obtained by directly supplying air. The gas supply system can provide for improved safety in operation as well as the ability to operate the sprinkler system primarily when filled with nitrogen supervisory gas.

Abstract: An improved system and method for detection and suppression of fire that addresses the elements of the fire tetrahedron (e.g., heat, oxygen, fuel-rich smoke) to detect and suppress fires is described. Embodiments are comprised of a processor in communication with a detector, a fan, and a number of dampers. Upon detection of a triggering condition by the detector, the processor causes signals to be transmitted to the fan and dampers. Resulting changes to dampers and fans redirects airflow to evacuate heat, oxygen, and fuel-rich smoke through one or more vents in the compartment in which the triggering condition was detected. Advantages of described embodiments include utilizing existing HVAC systems, removing elements of the fire tetrahedron to suppress fires, and reducing unnecessary damage that may be caused by prior art suppression systems (e.g., sprinklers).

Abstract: A dispenser and methods for transferring liquids are disclosed. The dispenser may include a capillary tube with tip having an aperture, a piezoelectric actuator coupled to the capillary tube at a location. Actuation of the piezoelectric actuator causes a pressure wave to propagate along the capillary tube toward the tip such that radial motion at the location is transmitted as distally extending axial motion of the tip, thereby causing a droplet of a predetermined volume to be ejected from the aperture. In some embodiments, the capillary tube has a modulus of elasticity in a range which dampens acoustical noise from the actuation and provides single drop stability over a range of drop sizes.

The sprayer system includes a substantially vertical tubular housing extending from a well base to a distal end from which water communicated to the sprayer system is discharged. The tubular housing includes an inner tubular casing slidably supporting a piston assembly which is movable from the well base to the distal end in response to water communicated from a source to the well base. The piston assembly includes a primary check valve that is biased into engagement with an associated seat and includes a spray nozzle located downstream of the main check valve. When water from the source is applied to an effective pressure area on the piston assembly, an upwardly directed force is applied to the piston assembly when water is delivered to the well base.
