Abstract: Provided are stowable rack systems and methods for transporting various payloads. A stowable rack system for hauling various payloads includes a trailer having a body with a top surface and a recessed well and a rack. The rack includes a plurality of A-frames, each A-frame movable between an upright position relative to the top surface of the trailer and a stowed position within the recessed well. When at least two A-frames of the plurality of A-frames are in the upright position the at least two A-frames are operable to carry a first payload. When the plurality of A-frames are in the stowed position the top surface is operable to carry a second payload.

Abstract: A device for aseptic delivery of biological material from a vial includes a tubular barrel, a filter assembly, and a dispersion assembly. The dispersion assembly is at least partially disposed within the tubular barrel. The dispersion assembly includes a dispersion element, a piston, and a one-way valve. The dispersion element is in fluid communication with the vial to disperse the biological material from the vial. The piston is disposed at the distal end of the dispersion assembly and is in sealing contact with the tubular barrel. The one-way valve forms a fluid passageway in fluid communication with the dispersion element and the tubular barrel. The one-way valve is configured to allow a flow of the dispersed biological material from the dispersion element, through the fluid passageway, and into the tubular barrel, and to prevent a flow of the dispersed biological material from the tubular barrel into the dispersion assembly.

Abstract: A rack and lifter system and method is described. The system includes a rack having at least a first engagement opening, and a lifter having at least a first engagement member and at least a first vertical extension member, wherein in use the at least a first engagement member interlocks with the at least a first engagement opening of the rack, and the at least a first vertical extension member extends to lift the interlocked lifter and rack, wherein the at least a first vertical extension member includes means for movement. The lifter may include a guiding-and-lifting member which lifts the lifter and guides the lifter into an interior space of the rack. The lifter may include a towing machine connection member which connects the lifter to a towing machine which positions the lifter within the rack and tows the connected lifter and rack.

Abstract: An FM signal or protocol analyzer (PA) system: The PA system is capable of analyzing the broadcast signal at many levels, from analysis of the physical RF link to comprehensive analysis of the subcarrier messaging. The PA system is built on a computer including special hardware and software. The custom hardware comprises at least one precision RF receiver and signal processing circuitry. The custom software includes data acquisition, data analysis and data presentation software. As a feature of the present invention, a PA system is designed to be "user friendly." As such, it operates in a windowing environment and makes extensive use of graphical displays. The PA system can operate in a networking environment so the receiver and signal processing circuitry can be physically distant from the user's display and keyboard, in another computer connected to the network.
