An electronic cigarette vaporizer includes a heating element and a microcontroller; the microcontroller monitors or measures external or ambient temperature and uses that as a control input. The control input automatically controls the power delivered to the heating element to ensure that the heating element operates at its optimal temperature. Where ambient temperatures are monitored or measured as very cold, then the power to the heating element is automatically increased to compensate.

An electronic cigarette vaporizer system includes a case and a vaporizer that is stored in the case; the system includes a non-contact sensor that detects release or withdrawal of the vaporizer from the case. When withdrawal of the vaporizer is detected, then the vaporizer electronic circuitry changes state, e.g. to a ready mode, or a pre-heating mode in which an inhalation detector is activated or to a heating mode, where an atomizing unit in the vaporizer is at least partly activated so that the vaporizer is fully heated when the first inhalation is taken.

Systems are provided for refueling a fuel tank of a motor vehicle via a funnel including an insert. In one example, a system may include a funnel including an insert coupled to an inner circumference of the funnel, the insert including a plurality of projections positioned on an inner perimeter of the insert. The plurality of projections may include a first projection spanning a first axial length, a second projection spanning a second axial length, and a third projection spanning a third axial length.

A volatile liquid refueling apparatus, which includes a probe including an outer collar, and a receiver including a receiving collar, where the outer collar of the probe and the receiving collar of the receiver are configured to join to create a vapor-tight enclosure, and where the receiver further includes a locking mechanism whereby the apparatus can be locked in an open position.

A volatile liquid refueling apparatus, which includes a probe including an outer collar, and a receiver including a receiving collar, where the outer collar of the probe and the receiving collar of the receiver are configured to join to create a vapor-tight enclosure, and where the receiver further includes a duel locking mechanism whereby the apparatus can be locked in either an open position or a closed position.

An electromechanically operated fuel nozzle having continuously adjustable flow rate settings between a closed position and maximum flow. The fuel nozzle includes a fuel dispensing pipe for dispensing fuel; an electromechanical valve device to control a flow of fuel in the fuel dispensing pipe, comprising an inlet pipe and an outlet pipe. The electromechanical valve device comprises at least one continuously variable flow electromechanical valve to control the flow of fuel; an electronic board for operating the at least one continuously variable flow electromechanical valve; and electric accumulator means for electrically powering the at least one variable flow electromechanical valve and the electronic board such that the predetermined portions provide the particular one of the flow rate settings. The electromechanical valve preferably comprises a servomotor controlled ball valve.

A fuel drip retention system includes a computer programmed to actuate one of a pump or a starter motor to generate a vacuum in an evaporation line between a fuel nozzle receiving port and a vapor canister. The vacuum is generated upon determining that fuel has stopped flowing into a fuel tank.
