MILWAUKEE, WI--(Marketwired - Nov 24, 2014) - Prolitec, Inc., the global ambient scenting leader, has been granted an important technology patent for its AirQ ambient-scenting systems, the company announced today. The U.S. Patent & Trademark Office awarded the Milwaukee-based company a patent last month for its method of controlling the operation of a diffusion appliance to treat the atmosphere within an enclosed space.

"Patents like this, coupled with additional proprietary technologies and methods we use in providing the AirQ ambient scent service, allow us to offer our clients a truly hi-fidelity scent experience unavailable from any other scent provider," said Richard Weening, CEO of Prolitec. 

Utilized in retail stores, hotels, casinos, spas, fitness centers and other commercial entities in more than 90 countries across the globe, Prolitec's AirQ systems convert aqueous or non-aqueous liquids into plumes of ultra-fine droplets measuring about 1 micron in diameter. These droplets rapidly transition to a dry vapor uniformly distributed throughout indoor spaces. AirQ's on-board computer, which functions independently or in conjunction with a building's HVAC unit, controls the system and gives users the ability to precisely adjust the intensity and occurrence of the scent effect.

"Even the finest of fragrances are not attractively presented if they are too strong or too weak," Weening noted. "This type of control system insures an accurate presentation that is faithful to the perfumer's art."

In its abstract, the U.S. Patent & Trademark Office said the patent had been awarded for "a method of controlling operation of a diffusion appliance to treat the atmosphere within an enclosed space. The method may include programming the operation of the appliance according to a control scheme specifying a flow rate of liquid to a diffusion means and a periodic operation of the diffusion means. Control schemes may be associated with different volumes of spaces to be treated by the appliance, the rate of decay of the liquid within the space to be treated and the level of concentration of the liquid desired within the space."
