A system for detecting water in an environment includes a first sensor configured to provide first feedback indicative of a temperature of the environment, a second sensor configured to provide second feedback indicative of a humidity of the environment, and an electronic circuit having a processor configured to execute one or more instructions stored on a memory of the electronic circuit. The one or more instructions are configured to receive the first feedback from the first sensor, receive the second feedback from the second sensor, generate a risk score by comparing the first feedback and the second feedback to baseline data stored on the memory of the electronic circuit, and provide an indication of a water detection event when the risk score is equal to or exceeds a threshold value.

Provided is a soldering apparatus including: a furnace body including a processing chamber in which boards are processed; a gasket provided at least to a part of the furnace body, and configured to seal the furnace body; a sealed space isolated from the processing chamber, and defined by the furnace body and the gasket; a gas supply apparatus configured to supply a first gas into the sealed space; and a measuring apparatus configured to measure one of pressure in the sealed space and concentration of a second gas in the sealed space.

Aspects and techniques of the present disclosure relate to a process of evaluating a pressurized fluid system including an automatic bleed valve arrangement therein for undesirable air leakage by diagnostically operating the automatic bleed valve arrangement. The disclosure also relates to methods of evaluating air presence in a pressurized fluid system sufficient to warrant bleed valve operation. Further, apparatus and features thereof are characterized.

A water leakage detection system includes: a solenoid valve that is provided to a water pipe having at least one feed-water valve on a downstream portion of the water pipe, and is configured to be set to at least one stage of a partially-opened state between a fully-closed state and a fully-opened state; a flow meter that is disposed on a downstream side of the solenoid valve; and a controller that controls an opening/closing state of the solenoid valve, and receives information on a flow rate detected by the flow meter. The controller detects water leakage in the water pipe when the solenoid valve is turned to the fully-closed state, and thereafter when the solenoid valve is set to the partially-opened state at a time point when a predetermined time elapses, and thereafter when the flow meter detects a flow rate.

Aspects and techniques of the present disclosure relate to a bleed valve system for bleeding fluid of a first, lower, specific gravity from a fluid of a second, higher, specific gravity, in a fluid system. The techniques can be used to provide a bleed valve system, for a pressurized fluid system, that is not sensitive to rotational orientation around a mounting axis.
