Abstract
Abstract A computer controlled odor mixing and dispensing system has an linear array of odorant containers arranged in an annular member. Each container is provided with a computer controlled metering delivery device which dispenses the odorant onto a rotating absorptive porus member. An air handling system forces air through the rotating member which mixes the odors deposited thereon and delivers the mixed odors to a user.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
168 words
A computer controlled odor mixing and dispensing system comprising: a hollow member having at least one opening in each of two spaced surfaces to define a fluid inlet and a fluid outlet; a plurality of containers each suitable for storing a different odorant arranged in an array and mounted in said hollow member proximate the opening defining the said fluid inlet; a plurality of controllable delivering means, one connected to each of said plurality of containers, for controlling, in response to control signals supplied by a computer, the volume of odorant dispensed from its associated container; a moving absorptive porus member mounted in said hollow member for receiving the odorants dispensed by said controllable metering delivery means; and, fluid pumping means mounted in said hollow member for establishing a fluid flow between said inlet and said outlet and through said moving absorptive porus member whereby odorants deposited on the said moving absorptive porus member are mixed by said fluid flow and motion and expelled at said fluid outlet.
Claim 2
Dependent Claim
168 words
A computer controlled odor mixing and dispensing system comprising: a hollow member having at least one opening in each of two spaced surfaces to define a fluid inlet and a fluid outlet; a plurality of containers each suitable for storing a different odorant arranged in an array and mounted in said hollow member proximate the opening defining the said fluid inlet; a plurality of controllable delivering means, one connected to each of said plurality of containers, for controlling, in response to control signals supplied by a computer, the volume of odorant dispensed from its associated container; a moving absorptive porus member mounted in said hollow member for receiving the odorants dispensed by said controllable metering delivery means; and, fluid pumping means mounted in said hollow member for establishing a fluid flow between said inlet and said outlet and through said moving absorptive porus member whereby odorants deposited on the said moving absorptive porus member are mixed by said fluid flow and motion and expelled at said fluid outlet.
Claim 3
Dependent Claim
38 words
A computer controlled odor mixing and dispensing system as set forth in claim 1 in which said hollow member is a cylinder and the fluid inlet and fluid outlet openings are located in the opposed planar end surfaces.
Claim 4
Dependent Claim
32 words
A computer controlled mixing and dispensing system as set forth in either claim 1 or claim 2 in which the odorant is a liquid and the controllable delivering means are piezo-electric pumps.
Claim 5
Dependent Claim
35 words
A computer controlled mixing and dispensing system as set forth in claim 3 in which the odorant containers are arranged in a linear array and the absorptive porus moving member is a slowly rotating disk.
Claim 6
Dependent Claim
34 words
A computer controlled mixing and dispensing system as set forth in claim 3 in which the odorant containers are arranged in a plurality of stacked cassettes and each cassette has a plurality of odorants.
Claim 7
Dependent Claim
44 words
A computer controlled mixing and dispensing system as set forth in either claim 1 or claim 2 in which the odorant is a solid and the controllable metering delivery means are heating elements for vaporizing the odorant as a function of a control current.
Claim 8
Dependent Claim
35 words
A computer controlled mixing and dispensing system as set forth in claim 6 in which the odorant containers are arranged in a linear array and the absorptive porus moving member is a slowly rotating disk.
Claim 9
Dependent Claim
34 words
A computer controlled mixing and dispensing system as set forth in claim 6 in which the odorant containers are arranged in a plurality of stacked cassettes and each cassette has a plurality of odorants.
