A handheld fluid meter includes a cartridge valve controlling the flow of fluid through the handheld meter. The cartridge valve includes a valve cartridge and a valve stem disposed within the valve cartridge. The cartridge valve guides the valve stem and provides the only sealing surface for the dynamic seals and control seal disposed on the valve stem. The handheld meter dispenses through a nozzle, which includes an overmolded stem tip that generates a laminar fluid flow as the fluid exits the nozzle. The overmolded stem tip is a compliant material. The handheld fluid meter includes circuitry configured to invert the orientation of a visual output provided by a display of the handheld fluid meter to facilitate installation of the handheld fluid meter for use in an oil bar application.

A supply control apparatus includes a display information output unit configured to output display information to allow a user to recognize an identifier of a supply object and information to prompt the user to decide on the supply object when the supply object is supplied to a supply destination container and a supply control unit configured to remove a supply limit for the supply destination container of the supply object when a decision operation in which the user confirming the display information decides on the supply object is detected.

When filling a vehicle with fuel, a person must touch and hold the dispenser nozzle by the handle 11, squeezing the trigger lever 13. This handle 11 is contaminated by fuel vapour, residue, bacteria, dirt and contaminants by previous usage of multiple persons touching and holding the handle 11 with contaminated hands. The present invention relates to a protective material dispenser 101 with protective material 103 therein, which is releasably couplable to such a fuel gun 2. In this way, a user may easily retrieve some of the protective material 103 from the dispenser 101 prior to touching the fuel pump hand grip 11, and then cover the hand grip 11 to protect his/her hands from making direct contact therewith.

An aerosol-generating article may comprise a liquid storage portion containing a liquid aerosol-forming substrate, and a hydrochromic material provided on the liquid storage portion. The hydrochromic material has a first colour when in the presence of or when in contact with the liquid aerosol-forming substrate and a second colour when in the absence of or when not in contact with the liquid aerosol-forming substrate. An aerosol-generating system may comprise the aerosol-generating article, an aerosol-generating element, and an aerosol-generating device. An aerosol-generating device may comprise an electrical power supply, an electronic photosensor, and a controller configured to control a supply of electrical power from the electrical power supply based on a value of an optical property sensed with the electronic photosensor.

A fluid management system includes an authentication device and a fluid dispensing meter, and the fluid dispensing meter includes a processor and a memory. The authentication device is configured to provide user-identification data to the processor. The processor is configured to recall approved user identities from the memory, to compare the approved user identities to the user-identification data received from the authenticator, and to control a trigger control mechanism between the activated state and the deactivated state based on the comparison of the user-identification data and the approved user identities.

A handheld fluid meter includes circuitry configured to invert the orientation of a visual output provided by a display of the handheld fluid meter and to modify the functionality of buttons that control scrolling on the display. The control circuitry inverts the orientation of the visual output based on a command provided to the control circuitry by a user or by a position sensor.
