The present disclosure is directed to systems and methods for controlling access to fuel repositories such as an underground gasoline storage tank located at a retail gas station. A method of the present disclosure may include sensing when a fuel access cover is removed from a pipe that leads to an underground fuel storage tank. Alternatively, or additionally, the method may include sensing when a fuel regulation device or an access panel of a fuel pump has been accessed. Systems consistent with the present disclosure may monitor both a set of fuel storage tanks access points and a set of fuel pump access points that control the flow of pumped fuel. Unauthorized access to fuel may result in an alarm being initiated. Such systems may also allow authorized individuals to access fuel storage tanks or metering devices of specific fuel pumps after providing authorization information to a computer.

Provided is a process that includes determining, by a computer system and using a volumetric flow sensor, that a target volume of a fluid has been pumped by a pump through a first leg of a hole system that is representable by a U-tube. The process includes determining, by the computer system and using a pressure sensor at the pump, whether a first pressure reading of the pump is substantially equal to a target pressure. The process further includes notifying, by the computer system and in response to the first pressure reading being substantially equal to the target pressure, that a target top of fluid in a second leg of the hole system has been satisfied.

Systems and methods for providing network connectivity and remote monitoring, optimization, and control of pool/spa equipment are provided. “Internet-of-Things” (IoT) functionality is provided for pool and spa equipment in a flexible and cost-effective manner. Network connectivity and remote monitoring/control of pool and spa equipment is provided by various components such as a network communication and local control subsystem installed in pool/spa equipment, and other components. Also disclosed are various control processes (“pool logic”) which can be embodied as software code installed in any of the various embodiments of the present disclosure.

An apparatus and method for preventing undue wear on a concrete pump relies upon monitoring a volume of water in a water box for cooling and lubricating pumping seals on a material pumping piston within a material pumping cylinder. The apparatus includes a water level sensor to generate signals corresponding to a water level in the water box. The signals are received at a computing device including a central processing unit (CPU) to apply an algorithm drawn from the memory to determine whether the water level in the water box is sufficient for operation of the concrete pump and if not sufficient, to generate a water level alert. The CPU sends a water-level alert and in response to the alert, to execute a pump-preserving action. Such a pump-preserving action may include sounding a klaxon alarm; displaying an alert; playing a recorded warning; and shutting down operation of the concrete pump.

In a system and method for supervisory management of fluid pipeline/LNG plant/gas plant/refinery/offshore oil and gas platform allowing simultaneous execution of commands at all control points, significantly increasing the speed at which an optimal set-point can be achieved in comparison to manual entry of commands. The pipeline/LNG plant/gas plant/refinery/offshore oil and gas platform control system has a cascade control configuration that can operate in conjunction with existing pipeline/LNG plant/gas plant/refinery/offshore oil and gas platform protection systems. The control room operator can activate automatic operation via the supervisory management system, and can subsequently command that the system switch back to manual control instantaneously. Dynamic models predict operating conditions of pipeline/LNG plant/gas plant/refinery/offshore oil and gas platform processes subject to constraints on pressure and other operating parameters. A steady-state optimization layer, operating in conjunction with real-time control, determines optimal states without operator intervention.

A substrate processing apparatus configured to perform a preset processing on a substrate includes a pipe through which a liquid flows; a liquid leakage collector configured to receive the liquid leaking from the pipe; a first detector provided within the liquid leakage collector, and configured to detect the liquid; a second detector provided at a position higher than the first detector within the liquid leakage collector, and configured to detect the liquid; an indicator configured to notify liquid leakage information indicating a liquid leakage; a power supply configured to perform a power feed to the substrate processing apparatus; and a controller configured to control the indicator to notify the liquid leakage information based on a detection result of the first detector, and control the power supply to stop the power feed to the substrate processing apparatus based on a detection result of the second detector.

The invention relates to a method for controlling a concentration of dissolved oxygen in a volume (V) of water (W), wherein a device (1) for dissolving oxygen in water (W) is submerged in said volume (V) of water, wherein oxygen is injected by the device (1) with an adjustable flow rate into a main water stream (W′) sucked into a housing (100) of the device (1), and wherein the oxygen enriched main water stream (W′) is discharged by the device (1) out of the housing (100) of the device (1) into said volume (V) of water (W), and wherein a current concentration of oxygen dissolved in the sucked main water stream (W′) is measured with an oxygen probe (6) that is integrated into the housing (100) of the device (1), wherein said current concentration of dissolved oxygen is transmitted in a wireless fashion to a hand-held device (9) of an operator, and wherein the flow rate of the injected oxygen is controlled such that the measured current concentration of dissolved oxygen approaches a pre-defined reference value.

A system is provided for tracking, in a distributed water infrastructure, water usage by category. The system may comprise at least one processor configured to receive from at least one sensor associated with the distributed water infrastructure signals indicative of water usage in the distributed water infrastructure.

A bed system includes microclimate control capabilities for providing quality sleep experience. The bed system can include a microclimate control subsystem configured to supply conditioned air (e.g., heated or cooled air) to a mattress, or draw ambient air from the mattress, to achieve a desired temperature at the top of the mattress. Utilizing supply of conditioned air to provide air at desired temperature to the mattress system, or utilizing air suction to drain heat away from the mattress system, can provide precise microclimate control at the mattress, thereby permitting conformable sleep.
