    • An exemplary apparatus includes a sensor array configured to sense a gas stream temperature, pressure, and humidity. The sensor array includes a plurality of sensors, each configured to sense at least one of the gas stream conditions. The apparatus further includes an electronic control unit comprising a memory storage device, a condition evaluation module, a display module, and a wireless transmission module. The memory storage device stores a plurality of condition parameters, each condition parameter corresponding to one of the gas stream conditions. The condition evaluation module is configured to determine if one of the sensed conditions violates one of the corresponding parameters, and is further configured to output a warning command in response to the determining. The display module is configured to display information relating to at least one of a sensed condition and a condition parameter. The wireless transmission module is configured to wirelessly transmit data relating to at least one of the warning command and one of the sensed conditions.

    • The invention relates to a hydraulic circuit which makes it possible to perform maintenance on a stack valve of the hydraulic circuit and to perform various functions such as flushing of the circuit and a trial run in parallel with the maintenance, and relates to a composite valve used in the hydraulic circuit. In the hydraulic circuit, the composite valve is interposed between the stack valve and a hydraulic power supplier and between the stack valve and a multifunction valve coupled to a hydraulic device. The composite valve includes: stop valves opening/closing communication between the hydraulic power supplier and the stack valve and stop valves opening/closing communication between the stack valve and the multifunction valve; and bypass circuits including stop valves opening/closing communication between the hydraulic power supplier and the multifunction valve, the bypass circuits provided closer to the hydraulic power supplier than the stop valves. This structure makes it possible to perform repair, checking, and/or maintenance on the hydraulic power supplier and the stack valve; flushing; and repair, checking, maintenance, and/or a trial run of the hydraulic device, simultaneously. The composite valve has uniform circuit configurations, which facilitates production of the valve.
