Abstract: Systems and methods for the remote testing of a pressure switch, particularly a supervisory switch in a fire sprinkler system. The systems and methods detected a decrease in pressure below a target low threshold and above a modified high threshold where the modified high threshold is moved during testing to allow for testing without need to increase the pressure in the system substantially above a supervisory pressure.

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: A monitoring and testing system which is designed to automatically seal off the system from its gas supply and monitor internal pressure during that time to perform regulatory testing. The scheduling can be automated and can be done without maintenance personnel having to monitor the time passage and pressure manually. The system may also be designed to monitor operation of the air compressor, or related gas supply device, and evaluate if the operation of the gas supply is operating in a fashion indicative of a larger than desired leak. This effectively allows the system to monitor pressure changes during regular operation and on a somewhat continuous basis.

Abstract: Systems and methods for the remote testing of a paddle-type flow detector, such as are common in fire protection systems. Specifically, the systems and methods provide for mechanical movement of the vane to test activation of the flow detector under a flow condition, and which measure the amount of time the vane takes to return to the ready position to verify the presence of a paddle on the vane.

Abstract: A packaging system for pharmaceuticals is provided. The system includes a box having an opening, a pouch strip positioned within the box. The pouch strip includes a continuous series of sealed pouches rolled into a spiral with a first end and a second end. The opening in the box is of a shape configured to accommodate the cross section of the sealed pouches such that the pouch strip may be pulled through the opening outwardly from the box.

Abstract: A golf puffer has a cylindrical tube mounted horizontally behind the putter face with its front end aligned behind the sweet spot. The rear end of the tube is open. This tube acts as a resonant structure producing an enhanced characteristic sound when the sweet spot on the putter face strikes a golf ball. In addition, the tube typically has a diameter larger than that of a golf ball. The golfer's view of the cylindrical tube enhances the golfer's ability to correctly line up a putt by using the visual peripheral corridor created when the puffer is swung back and forth over the golf ball along the golfer's intended swing path prior to addressing and putting the golf ball.

Abstract: Methods and systems for evaluating a material sample is provided. The system includes a material sample holder including a first flange having an aperture therethrough, a second flange having an aperture therethrough, the first and second flanges configured to frictionally hold a material sample sandwiched therebetween, a waveguide coupled to a first end of each of the first flange and the second flange, each waveguide configured to direct electromagnetic waves through respective apertures, a waveguide adapter communicatively coupled to a second end of each waveguide, and a control unit electrically coupled to the wave source, the control unit configured to control the waveguide adapter to transmit and receive electromagnetic wave signals.
