US Patent:

20180036448, Feb 8, 2018

Filed:

Aug 2, 2017

Appl. No.:

15/667570

Inventors:

Todd H. Becker - Ridgefield CT, US
Thomas A. Conroy - Newtown CT, US
David L. Langton - Marblehead MA, US
Christopher H. Patstone - Northampton MA, US

International Classification:

A61L 9/12
A61L 9/04

Abstract:

Aspects of the present disclosure include a method of managing scent in an environment, which includes disposing at least one scent diffusion device within an environment, wherein the at least one scent diffusion device comprises a communications facility that enables transmitting signals to and receiving signals from a remote computer, receiving at least one target value of a scent parameter for the environment at the remote computer, and controlling, via the remote computer, diffusion of a liquid from a source of the liquid in fluid communication with the at least one scent diffusion device to achieve the target value of the scent parameter. Controlling a diffusion rate of the liquid includes altering at least one of a voltage and a duty cycle applied to at least one component of the diffusion device.

Abstract:

Systems and methods for managing scent in an environment include disposing scent diffusion devices within the environment, wherein the diffusion devices comprise a communications facility that enables transmitting signals to and receiving signals from a non-fragrance dispensing, wide-area network gateway device that receives communication and control functions from a remote computer for distribution to the plurality of scent diffusion devices. A sensor in the environment transmits sensor data to the remote computer. A scent parameter for scenting the environment is received at the remote computer. Diffusion of a liquid from the scent diffusion devices is controlled by the network gateway device the to achieve the scent parameter, wherein controlling includes setting or adjusting an operation parameter of one or more of the scent diffusion devices in response to the sensor data.
