Abstract: An air freshener that has a source of air freshening chemical with a fan that is controlled either by an optical device that senses light or a motion detector is disclosed. When a light is turned on or motion is detected, the fan will be activated for a predetermined time period. In certain embodiments, the fan will stop turning after a predetermined time. In certain preferred embodiments the source of air freshening chemical is disposed beneath the fan and allows fragrance to be delivered over time without the fan. The additional airflow provided by the fan causes more volatile fragrance chemicals to be removed from the source of air freshening chemical and admitted into the environment. Preferably, a microprocessor controls the fan so that a “burst mode” is created by controlling the frequency and intensity of the pulses of air freshener that are emitted. Also disclosed is a system for delivering a volatilized chemical integrated into a robotic vacuum cleaner.

Abstract: The present invention combines an air freshener that has a source of air freshening chemical with a fan that is controlled either by an optical device that senses light or a motion detector. When a light is turned on or motion is detected, the fan will be activated for a predetermined time period. In certain embodiments, the fan will stop turning after a predetermined time. Alternatively, the fan can continue to be powered until the light source is turned off (or all motion ceases), and only then either immediately shut down, or shut down after a predetermined time period. In certain preferred embodiments the source of air freshening chemical is disposed beneath the fan and allows fragrance to be delivered over time without the fan. The additional airflow provided by the fan causes more volatile fragrance chemicals to be removed from the source of air freshening chemical and admitted into the environment.

Abstract: Apparatus and methods for fragrance sensory stimulation connected to a multimedia source that has at least one audiovisual signal connected to an audiovisual display, and also has fragrance information synchronized with the audiovisual signal is disclosed. In preferred embodiments, a fragrance generator processes the fragrance information into a fragrance signal and at least one fragrance control system accepts a fragrance signal as an input, and generates a control signal and a controlled airflow. In turn, a fragrance delivery system preferably comprising a plurality of fragrance chemicals in communication with the controlled airflow, selectively volatilizes the fragrance chemicals is so that a short burst of fragrance is sensed by the subject. In certain embodiments, the fragrance delivery system comprises an indexing turret containing a plurality of ports, each port containing one of said plurality of fragrance chemicals.

Abstract: Apparatus and methods for emitting fragrance connected to an electromechanical device such as a robotic vacuum cleaner are disclosed. In preferred embodiments, a fragrance generator processes information generates a control signal and a controlled airflow. In turn, a fragrance delivery system in communication with the controlled airflow selectively volatilizes fragrance chemicals that are then selectively delivered by the device. In certain embodiments, the fragrance delivery system comprises an indexing turret containing a plurality of ports, each port containing one of said plurality of fragrance chemicals. In other preferred embodiment, a multiport micro-valve or array of such valves contains an absorbent material impregnated with a fragrance in each port.

Abstract: Apparatus and methods for fragrance sensory stimulation connected to a multimedia source that has at least one audiovisual signal connected to an audiovisual display, and also has fragrance information synchronized with the audiovisual signal is disclosed. In preferred embodiments, a fragrance generator processes the fragrance information into a fragrance signal and at least one fragrance control system accepts a fragrance signal as an input, and generates a control signal and a burst of compressed gas. In turn, a fragrance delivery system preferably comprising a plurality of fragrance chemicals in communication with the burst of compressed gas selectively volatilizes the fragrance chemicals so that a short burst of fragrance is sensed by the subject. Preferably, this short burst is followed by a purging burst that clears the fragrance so that another subsequent fragrance is easier to sense. The compressed gas may be generated by a source of compressed gas or a compressor.
