United States Patent 9,635,886 disclosed an electronic cigarette with a thermal flow sensor based controller as shown in the following figure.

The controller comprises a housing; a battery, a controller assembly; an air for allowing air to enter into the housing, a mouthpiece; a fluid reservoir; an atomizer; at least a light emitting diode; and a display. The thermal flow sensor is fabricated using micro-electro-mechanical systems (MEMS) technologies which is amenable to create the electronic cigarette with a thermal flow sensor based controller having stable evaporated liquid delivering, immediately response to smoker inhalation, like normal cigarette inhalation resistance, low power consumption, and no accidental actuation take place.

The controller has been used for new electronic cigarettes recently launched by Blu MAX in Brighton.

The new generation of e-cigarette, blu MAX™ boasts Responsive Draw™ technology that gives users complete control over their in-hale. The innovation has been created to provide smokers and vapers with an experience closer to smoking a cigarette than ever before, without the harmful tobacco or tar substances.

Responsive Draw™ is unlike any other technology in the e-cigarette market; responding to the strength of the in-hale, users can take in as much or as little vapour as they like, depending on their needs and mood. The sleek new e-cigarette also imitates the visual sensations of traditional drawing with its intelligent light system that illuminates with the intensity of the draw. “blu MAX is different from other vaping products due to its ‘Mass Air Flow’ technology making it the first electronic cigarette that adapts to the user’s draw.

In other words, vaping blu MAX is more enjoyable, since this is the first e-cigarette that responds to the intensity of your draw.” Titus Wouda Kuipers, CEO Fontem Ventures. blu MAX™ will be available on sale from the 17th November, exclusively in Brighton stores.
