A dispenser interface module connects with an existing main processing board of a fuel dispenser via an existing data port of the main board and via a current loop communication link connection of the main board. The dispenser interface module determines an idle condition of the dispenser from analysis of signals on the link, without disturbing the signals on the link, and only performs actions such as reboot or software update of the main board, or retrieval of data from the main board through the data port, during the idle condition. The dispenser interface module may compress data retrieved through the data port by removing previously retrieved records from the retrieved data. The dispenser interface module instructs a communication module to wirelessly transmit the compressed data to a remote server for analysis. The communication module wirelessly receives, and forwards to the dispenser interface module, reboot or update messages and instructions.

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.

A device for controlling refueling of hydrogen includes one or more hydrogen refueling facilities for refueling a hydrogen-powered vehicle with hydrogen, and a controller that collects state information and control data of the hydrogen refueling facilities, performs artificial intelligence learning based on the state information and the control data, and controls operations of the hydrogen refueling facilities based on the learning result.

A fuel island redundant monitoring system having sensors of varying purpose to transmit data signals to dual remote monitoring stations. One monitoring site is a live monitoring station manned by personnel. The other monitoring station is a data receiving station utilizing unmanned machines, e.g., computers. The unmanned data station is capable of transmitting information to the manned monitoring station, to local fuel island managers and/or to local emergency responders, and/or to control equipment at the fuel island. The manned monitoring station is capable of transmitting commands or inquiries to the unmanned data station and/or to control equipment at the fuel island, and/or to local fuel island managers and/or to local emergency responders. Sensors may be dedicated to either the unmanned data station or the manned live monitoring station, or may send data to both stations.

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.
