The present invention is a water damage prevention system that has a residential or industrial / commercial facility water supply interruption system. The system is comprised of a remotely controllable base station with shut-off / on mechanism that is in wireless or wired communication with a convenient controller. The base station with shut-off / on mechanism is interposed within a water line from a water main to the living or operating quarters portion of a residential or a industrial / commercial facility or building, such that activation of the base station with shut-off / on valve operates to prevent flow of water from the water main to the living quarters when the residential home or industrial / commercial facility or building is vacated or unsupervised. In this manner, damage to the living quarters or the industrial / commercial facility or building from failure of water pipes running through the living or working quarters is prevented during times that the shut-off mechanism is activated.

In a vehicle air conditioner where air blown into a passenger compartment is heated in a heater core using cooling water for cooling a fuel cell system as a heating source, a flow amount of cooling water flowing into the heat core is controlled by a control valve based on a surplus heat quantity of the fuel cell system and a necessary heat quantity of the passenger compartment. Further, when the surplus heat quantity of the fuel cell system is smaller than the necessary heat quantity, an insufficient heat quantity is supplemented by a supplementary heater.

A pinch valve includes a spring disposed between a movable iron core of a solenoid and an end cover thereof, and which urges the movable iron core toward the side of a tube provided in a body. An elastic force of the spring is set to be smaller than a reactive force of the tube that is applied to a valve plug. In a non-excited state of the solenoid, the valve plug is pressed toward the solenoid by the reactive force of the tube, so as to enable a fluid to flow through a flow passage of the tube. Conversely, in an excited state of the solenoid, since an attractive force of the movable iron core toward the tube is added to the elastic force of the spring, the valve plug is pressed in opposition to the reactive force of the tube for thereby blocking the flow passage.

Disclosed are methods, systems, and computer program products for performing temperature standardization of the volume of a liquid product from a distributor to a consumer. Using a volume measurement device and a temperature measurement device located at a rack, a storage tank, and a dispenser, a gross volume and temperature of the liquid product at, respectively, the rack, the storage tank, and the dispenser can be measured. Volume data indicative of the gross volume and temperature data indicative of the temperature can be generated. A time-stamp system at each of the rack, the storage tank, and the dispenser allocates a time-stamp to each of the volume data and the temperature data so that a reconciliation process can use each of the time-stamps, the temperature data, and the volume data to reconcile gross to net volumes at a single point in time.

Disclosed are methods, systems, and computer program products to prevent a delivery vehicle from making an unauthorized delivery of liquid product to a liquid product storage tank at a retail store facility. A retail system and / or a centralized inventory management system can monitor one or more tanks at the retail facility for liquid product delivery from the carrier. The retail system and / or the centralized inventory management system can automatically interrupt delivery of liquid product when the delivery vehicle begins to delivery the liquid product to an unauthorized tank.

Current sensing resistors are connected directly to output terminals of MOSFETs forming the series switching stage of a PWM sinewave dimmer. An analog sensed current signal is coupled through an EMI resistant current link to comparators that provide an overcurrent indication in response to an overcurrent condition. A logic circuit overrides PWM control signals from a programmable controller, and operates drivers to render the series switching stage nonconductive and to render a clamp switching stage conductive until after the end of the current PWM duty cycle power on segment. The logic circuit sends an overcurrent signal through an optocoupler to an input of the programmable controller. The input of the controller is polled at a clock frequency for overcurrent signals and if the count exceeds a limit in any half cycle, or a maximum sum in sixteen half cycles of the AC supply, the series switching stage is rendered nonconductive and the clamp switching stage is rendered conductive pending a reset signal.
