A device control system including a wearable device and a server. The wearable device includes a device that ejects a fragrance material, a biological sensor, and a computer. The computer transmits biological data to the server, receives a first control signal, and causes the device to eject a fragrance material upon receipt of the first control signal. The server includes a computer. The computer receives the biological data, estimates users emotion from the received biological data, and in a case where it is determined that the user has positive emotion by using a result of the estimation, (i) transmits the first control signal to the wearable device and (ii) transmits, to an aroma device, a second control signal for causing the aroma device to eject a fragrance material at a predetermined timing.

Described herein are systems and techniques for generating odor impressions of scents. Some embodiments provide odor impressions in an extended reality (XR) environment (e.g., virtual reality (VR) and/or augmented reality (AR)). The system determines spatial characteristics of an odor impression that is to be generated in the XR environment. The system generates one or more commands for generating the odor impression based on the spatial characteristics. The system transmits the command(s) to a controller for execution. The controller may control dispersal of scented media to generate the odor impression.

A component for a vehicle interior configured to dispense scent in a vehicle interior is disclosed. The component may comprise a scent-dispensing apparatus comprising a module configured for at least one scent-dispensing cartridge (removable/replaceable) containing scent media. An actuator may be configured to operate the module in a bypass mode or for selection/actuation of a cartridge. A selected cartridge may be actuated from a sealed state to prevent airflow through scent media to an unsealed state to allow airflow across/through scent media and into the vehicle interior. The actuator may comprise a mechanism (e.g. slider, cam mechanism); each cartridge may comprise a valve mechanism actuated by the actuator; each mechanism may comprise a spring. The module may comprise a fan to provide airflow. The component may provide a user interface. The component may comprise a console, overhead console, floor console, center console, etc.

A scent delivery system includes scent delivery units that are configured to deliver scent at a variable scent level by being turned on and off successively according to a variable duty cycle. The scent delivery system also includes a central controller configured to control the scent delivery units by generating command data based on a scenting schedule that indicates a desired activation time for more than one scent delivery unit. The scenting schedule is configured to further indicate a scent level bias to be applied to base scent settings that are associated with different scent delivery units. The central controller is configured to generate the command data, based upon a variation in the scent level bias, that takes into account a corresponding variation to duty cycles associated with different scent delivery units and to communicate the command data to the different scent delivery units.

A method for dispensing fluid materials includes: a plurality of fluid storage chambers with each of the plurality containing a stored fluid; at least one MEMS dispensing element disposed in fluid communication with at least one of the plurality of fluid storage chambers; a control element disposed in electrical communication with the at least one MEMS dispensing element and comprising a memory component; a power supply disposed in electrical communication with the at least one MEMS dispensing element and the control element; and a user interface disposed in electrical communication with the control element. The memory component contains programmed instructions which, when executed by the control element cause the system to randomly dispense a first fluid from a first fluid storage chamber, and randomly disperse a second fluid from a second fluid storage chamber.

A device comprises a delivery engine comprising a volatile composition and a microporous membrane, and an evaporation assistance element. In some embodiments the device includes a fan is configured to move a volume of air over the microporous membrane to facilitate evaporation of the volatile composition into the atmosphere.

A refill for holding at least two compositions comprises a container including a body and first and second compositions disposed within the body such that the first and second compositions are substantially separated and the second composition is disposed above the first composition. The refill further includes a tube disposed within the body of the container such that the tube contains the first and second compositions, wherein the tube has an inner diameter and an outer diameter. Still further, the refill includes a wick disposed within the tube, wherein the wick contains the first and second compositions and has a diameter that is smaller than the inner diameter of the tube to create a gap between the wick and the tube.

The distribution carousel (1) comprising a body (10) comprises a set of receptacles (13) of a set of reservoirs (20, 21) for fluid containing a fluid that is to be distributed, each one of the reservoirs comprising a distribution orifice (22) having a distribution axis (X), the set of receptacles being arranged in the body such that, once the reservoirs of the set of reservoirs are in place in the associated receptacles, the distribution axes of the reservoirs of the set of reservoirs intersect in a service region (Z) around a single mixing point (P).

The present disclosure relates to an odor generator device based on an intelligent mobile terminal, including: a communication module configured to establish a communication connection with the intelligent mobile terminal and acquire electronized odor information from the intelligent mobile terminal; a data processing chip connected to the communication module to parse the received electronized odor information and generate a corresponding odor generating instruction according to decoded data; and an odor generator connected to the data processing chip to generate a corresponding odor according to the odor generating instruction and emit the odor. The present disclosure further provides an odor generating method based on an intelligent mobile terminal, comprising: an electronized odor information acquisition step, an electronized odor information parsing step, and an odor restoring step.
