Various devices and systems for display surface temperature reduction are provided. For example, such a device can comprise a vented display having a display assembly configured to generate and project images, a backlight assembly configured to generate light to illuminate the display assembly, and an air gap that separates the display assembly from the backlight assembly and that is configured to permit a flow of air through the air gap to thereby facilitate the transfer of heat from the display assembly to the air flowing through the air gap to cool the display. For example, such a system can comprise a convective cooling system that is configured to direct a flow of cooling air across an exterior surface of a display and thereby lower the temperature of the exterior surface.

The system includes piping networks to deliver the various desired liquid necessities from a central bulk liquid storage station directly to the consumer in a trackable manner. The liquid distribution system includes a central bulk storage station, a piping network, a central data receiving and processing server, and a dispensing system for dispensing the liquid through one or more dispensing points.

Apparatus (2) for monitoring a set of fuel dispensers (10.sub.1, 10.sub.2, . . . 10.sub.N) of filing stations (1.sub.1, 1.sub.2, . . . 1.sub.M), for providing fuel stored in tanks (11) to vehicles, may include interfaces (21) to receive measurements from output probes (30.sub.1, 30.sub.2, . . . 30.sub.N) measuring fuel flowing through nozzles (11.sub.1, 11.sub.2, . . . 10.sub.N); measurements from amount probes (31) measuring a stored amount contained within the tank; and receipt data of fuel delivered; a memory (22) to store at least part of said measurements, and a computing means (23). The computing means may be configured for: determining two subsequent fuel deliveries for which stored amounts measured at the start of said deliveries are substantially equals; determining a suspicious situation by comparing said receipt data corresponding to said subsequent fuel deliveries with the sum of measurements provided by said output probes during the time period between these two subsequent deliveries; and triggering an action when a suspicious situation is determined.

A liquid volume transfer system includes: a liquid infusion device, including a first communication module, a first controller and a first flow rate detecting module; a liquid container, including a second communication module; and an unmanned aerial vehicle, including a third communication module, a third controller and a second flow rate detecting module. The first controller obtains a remaining liquid volume value from the second communication module through the first communication module, and determines a target infused liquid volume value based on the remaining liquid volume value and a total infused liquid volume value; after completion of infusion, the total infused liquid volume value is sent to the second communication module through the first communication module; the third controller obtains the total infused liquid volume value through the third communication module, and sends the remaining liquid volume value to the second communication module through the third communication module after spraying.

The system described herein employs electronic technology to improve the ability to dispense liquid from a container. The container can be programmed to dispense a specific amount of liquid, at a specific time. It can be voice-activated and connected to other electrical components such as a laptop or alarm system. The system may be used in laboratory equipment, medicine bottles, and food processors, although alternate methods may also be used.

A system determines that a fuel dispensing operation may be anomalous. In response, the system accesses fuel inventory data that indicates fuel levels in a fuel tank within a threshold period. The system determines a measure amount of fuel that left the fuel tank based on the fuel inventory data. The system determines a calculated amount of dispensed fuel associated with one or more fuel dispensing operations within the threshold period. The system compares the measured amount of fuel that left the fuel tank with the calculated amount of dispensed fuel. The system determines that the measured amount of fuel that left the fuel tank is more than the calculated amount of dispensed fuel. In response, the system confirms that the fuel dispensing operation is anomalous and communicates an electronic signal to the fuel dispensing terminal that causes the fuel dispensing terminal to stop dispensing fuel.

An improved fluid transfer accuracy, information collection, and overall management. A system may utilize a pump to transfer fluid from a source to a target vessel, a meter for measuring an amount of fluid transferred, a density meter to detect actual fluid density, and a control unit to determine actual fluid transfer amount based on density. As an example, a fluid flow meter can be coupled with a flow conduit to determine fluid volume, along with the density meter to detect real-time density of transferred fluid. During a fluid transfer event, such as aircraft refueling, LPG fueling, or other refined fuels or valuable liquids, fluid volume can be converted to fluid weight in real-time based on actual density. The real-time fluid weight can be used to determine if a target fluid weight has been reached, and fluid flow can be shut off at the appropriate time.

A machine for replacing used transmission or power steering fluid in a vehicle with new transmission or power steering fluid includes a frame having a housing. The machine includes a pair of service hoses that extend from the machine and connect to the vehicle for placing the machine in the fluid flow. New, used, and axillary fluid tanks are provided. A pump and a manifold are associated with two of the tanks. The pumps provide for the selective withdraw or insertion of fluid into or out of the tanks. A display on the housing presents an operator of the machine with various tasks or options the machine can perform. A processor controls activation of the pumps and other electrical components based on inputs received by the display. Scales are provided under one or more of the tanks for determining the amount of fluid going into and out of the tanks during the exchange process.

A system detects a fuel dispensing operation that indicates fuel is being dispensed from the fuel dispensing terminal. The system determines an identifier value associated with a volume of fuel dispensed from the fuel dispensing terminal. The system determines a measured volume per unit time parameter associated with the fuel dispensed from the fuel dispensing terminal by dividing the determined identifier value by a unit parameter. The system compares the measured volume per unit time parameter with a threshold volume per unit time parameter. In response to determining that the measured volume per unit time parameter is less than the threshold volume per unit time parameter, the system communicates an electronic signal to the fuel dispensing terminal that instructs the fuel dispensing terminal to stop dispensing fuel.

A refrigerator includes a cabinet defining a fresh food compartment and a door pivotally mounted to the cabinet and including an interior surface in communication with the fresh food compartment when the door is closed. A shelf unit is disposed adjacent the interior surface of the door, and a container is supported by the shelf unit. A fill mechanism is positioned vertically above the container and the container is configured to receive liquid from the fill mechanism. A sensor is configured to sense a property of the container or liquid received in the container. A control is in communication with the sensor and regulates a dispensing of liquid into the container based upon the sensed property. The sensor utilizes a magnetic sensing element located adjacent to the container.
