Abstract: An apparatus for dispensing solid articles includes a manifold assembly. The manifold assembly includes a manifold and a door assembly. The manifold has a plenum and an inlet port in fluid communication with the plenum. The door assembly includes a door panel and a shield. The door panel is selectively moveable between a closed position, wherein the door panel restricts airflow through the inlet port, and an open position, wherein the door panel permits airflow through the inlet port. The shield defines a pocket to receive the door panel in the open position and thereby reduce or restrict flow of air behind the door panel.

Abstract: A fan module is disclosed. The fan module includes a base, at least one first side coupled to the base, and a plurality of fans coupled to the base. The plurality of fans are configured to substantially disperse thermal energy away from one or more electronic components in an enclosure to maintain a current temperature of the one or more electronic components below a critical temperature. The fan module further includes a connector mounted on the at least one first side and coupled to provide power to the plurality of fans. When one of the plurality of fans ceases to operate, the remaining fans in the plurality of fans continue to substantially disperse thermal energy away from the one or more electronic components while maintaining the current temperature below the critical temperature.

Abstract: A filter assembly comprising a cover plate and a filter support. The filter support includes a length extending perpendicularly from an edge of the cover plate, a first edge and a second edge defining a height, a first U-shaped filter support extending from the first edge and a second U-shaped filter support extending from the second edge. The first U-shaped filter support and the second U-shaped filter support are configured to hold a filter there-between.

Abstract: A method for switching digital signals is disclosed. From an external control connection, the method configures a plurality of digital signal paths with at least one crossbar switch and controls a plurality of input and output connections for the digital signals based on the crossbar switch configuration. The method further involves automatically revising the digital signal routing without manual intervention based on configuration commands from the external control connection.
