A spray chamber valve control system for ensuring that coolant is sufficiently available at the intakes of pumps in a spray cooled environment regardless of the attitude, acceleration or deceleration of a spray chassis. The spray chamber valve control system includes a spray chassis with an interior portion for spray cooling electronic devices, a plurality of valves positioned within the inner corners of the spray chassis, and a control unit in communication with the valves for controlling the operation thereof. The control unit ensures that at least one valve is open at all times. The control unit also provides a recovery routine for when only one valve is open during a valve state change.

A spray cooling system for extreme environments for providing a desired enclosed environment for electronic devices regardless of external environmental conditions. The spray cooling system for extreme environments includes an enclosure that isolates the electronic components from the external environment, a spray unit within the enclosure for thermally managing one or more electronic devices, a pump unit fluidly connected to the spray unit, a heat exchanger unit fluidly connected to the pump, and a control valve fluidly connected between the heat exchanger unit and the pump. An independent chamber preferably houses a heater unit, a first power supply and a control unit, whereby the heater unit initially heats the coolant within the independent chamber to a minimum operating temperature prior to operation of the electronic components.

An input/output transition board system for collecting and distributing input/output signals between a backplane board and an I/O board while allowing for additional electronic devices. The input/output transition board system includes a transition board having at least one front connector and at least one rear connector. The front connector is connectable to a corresponding rear panel connector within a backplane board. The rear connector is connectable to a corresponding front I/O connector of an I/O board. The transition board collects and passes the signals between the I/O board and the backplane board. The transition board is also preferably active with additional electronic devices connected to the transition board.

A ticket dispensing mechanism is disclosed having a housing, a worm and drive, an idler roller, and a drive roller that engages the worm. Rotating the worm rotates the drive roller to advance a strip of tickets placed between the drive roller and the idler roller. A sensor detects ticket movement and a control circuit controls the worm drive motor to rotate the worm until the appropriate number of tickets have been dispensed. A slotted mounting for the drive roller accommodates tickets of different thickness, and locks the tickets against unauthorized withdrawal.
