A flow rate measurement system measures, by using a flow rate measurement device, a flow rate of cleaning gas in a container storage facility including: a storage rack including supporting portions; a transport device that transports a container to the supporting portions; and a gas supply device that supplies the cleaning gas to the container supported by the supporting portions. The transport device and the flow rate measurement device are connected via a power line communicatively by wire or wireless. The flow rate measurement device measures the flow rate of the cleaning gas in a state in which the transport device has transported the flow rate measurement device and the flow rate measurement device is placed on a target supporting portion.

A drive circuit for a solenoid valve having a coil and a poppet configured to translate within the coil includes a drive switch operable to de-energize the coil to translate the poppet toward a closed position, a sensor configured to detect the poppet translating within the solenoid valve, and a drive circuit configured to energize and de-energize the coil of the solenoid valve to translate the poppet of the solenoid valve between an open position and a closed position. The drive circuit includes a controller configured to receive a closure signal from the sensor, determine a closing time of the solenoid valve based on the closure signal, determine a time delay between de-energizing the coil and the determined closing time, and determine a fluid flow value of fluid flowing through the solenoid valve based on the determined time delay.

A powertrain controller of a vehicle provides a fuel pump actuator signal indicative of fuel flow to a vehicle bus. A processor is configured to receive data from the vehicle bus. The processor performs an integration of the actuator signal to accumulate fuel usage of the vehicle, and periodically sends the accumulated fuel usage, vehicle speed, engine speed, engine status, and vehicle location to a remote server. A subset of accumulated fuel usage is retrieved for a set of the vehicles of a fleet traversing a route during a timeframe, the accumulated fuel usage compiled from fuel pump actuator signals. Fuel waste is computed for identified idle time periods within the accumulated fuel usage. Monetary waste is computed from the fuel waste. A report is generated including the monetary waste.

A method, computer program product, and system for suppressing rerouting in a navigational system which includes a processor monitoring movements of a vehicle relative to a planned route generated by a navigational system, where the planned route includes a trip from a point of origin to a destination and the navigational system includes program(s) providing navigational assistance to a driver during the trip. The processor detects a first movement of the vehicle which is a deviation from the planned route. The processor determines that the deviation is based on an intentional circumstance. The processor suppresses execution of rerouting functionality of the navigational system and pauses the program(s) providing navigational assistance. The processor detects a second movement of the vehicle that includes a resumption of the planned route and resumes the program(s) providing navigational assistance.

A method of detecting fluid flow through a solenoid valve in a fluid application system includes dispensing fluid through the solenoid valve, de-energizing a solenoid coil of the solenoid valve to close the solenoid valve and control a fluid flow through the solenoid valve, determining a closing time of the solenoid valve based on a signal from a poppet measuring sensor, determining a time delay between the de-energizing the solenoid coil and the closing time, and determining a fluid flow value based on the time delay.
