Patent number: 10242391Abstract: A system for creating custom fragrances is described that allows a customer to interact with an employee and a Perfumer's Organ to interactively select several scents for base, middle and top notes. They can then iteratively adjust the scents chosen. In one embodiment, the scents selected by a customer are provided to a computing device having a prestored table which separates the scents into variable potency scents having variable perceived strengths and normal potency scents having standard, equal perceived strengths. The table indicates the amount of each variable potency scent to use to normalize the strengths. The remaining normal potency scents are then added with an equal amount. In an alternative embodiment, predetermined mixtures are provided to the computing device and used as ‘training data’ to adjust the coefficients of a generalized formula to create a prediction equation fit to the training data.Type: GrantFiled: November 9, 2015Date of Patent: March 26, 2019Inventors: Danielle K.
