A scent dispenser includes a housing, holder having scent cartridge receiver(s) to removably hold scent cartridges, baffle(s) with a port which is positionable, actuator(s) (e.g., stepper motors), and a control subsystem that drives the actuators to position the baffles to selectively dispense scent from the scent cartridges. The scent cartridges can have passages, at least some of which contain scent media, and optionally one passage without scent media. The housing can be cylindrical and fittable in a cup holder of an automobile. The scent dispenser can have vents at a bottom, a grille at a top, and an air mover (e.g., fan) to create an air flow from the vents through the grille, passing through any scent channels which are aligned with the ports to dispense scent. One or more substrates (e.g., printed circuit boards) can have apertures (e.g., large central passage) to facilitate the air flow.

The present embodiments relate to selection and execution of one or more output actions relating to a modification of at least one feature of a vehicle. A series of sensors on a vehicle can acquire data that can be used to identify vehicle environment characteristics indicative of a status of a vehicle environment and an emotional state of the user. The vehicle environment characteristics and the emotional state can be processed using a user model that corresponds to a user to generate one or more selected output actions. The output actions can be executed on the vehicle to increase user experience. The output actions can relate to any of entertainment features, safety features, and/or comfort features of the vehicle.

A fragrancing device is disclosed. The fragrancing device includes a housing having an installation space and a longitudinal housing axis at which a carrier is arranged with contact. The carrier is provided separately with respect to the housing and includes a cover part that covers an installation space opening of the installation space. A carrier part having at least one fragrance cartridge receptacle for receiving a fragrance cartridge is provided. A guide stop is disposed axially in a direction of the housing axis between the carrier and the housing for guiding the carrier as part of a plug-in movement relative to the housing along the housing axis. The guide stop includes a guide pin and a guide pin receptacle.

An apparatus and method for cleaning contaminated air in an enclosed space, such as a transportation trailer or a shipping container. An air mover in the space circulates contaminated atmosphere from an area of low pressure to an area of higher pressure. The resulting pressure differential is used to draw a reverse, partial air flow through an air cleaning device. The repeated cycling of a portion of airflow results in cleaning of the atmosphere and a general reduction of the contaminant from the enclosed space.

Embodiments of the present disclosure relate to a sensory experience providing apparatus for providing a sensory experience based on sound in a vehicle, and a method thereof. The controller is configured to receive a sound played in the vehicle, extract a sound feature from the received sound, generate sensory information based on the extracted sound feature, and provide a sensory experience based on the sensory information.

The present invention discloses an air quality monitoring device that can measure the hazardous gas contents, including benzene, formaldehyde and VOCs, and other air quality measurements inside train cars in real time. The air quality monitoring device can be installed inside a train car, either in the middle of the car, or at the end, or other locations. Each air quality device is equipped with a unique ID (e.g., MAC address, IP address, and RFID), which can be associated with a car or location inside the train. When hazardous gas level in a train car exceeds the safety level, this car or location can be identified and an air quality control unit injects or sprays photocatalyst material to the air to improve the air quality.

A method is disclosed comprising drawing air into a robotic vapor device, exposing the drawn air to a sensor to detect one or more constituents in the drawn air, determining measurement data for the one or more constituents of the drawn air via the sensor, receiving a parameter from a transportation vehicle system, determining one or more vaporizable materials to vaporize based on the measurement data and the parameter, and dispensing a vapor comprised of the one or more vaporizable materials from the robotic vapor device.

A replaceable cartridge for a scent dispensing system includes a scent medium having at least one scent carrier and a body surrounding a chamber for housing the scent medium. A surface area of the scent medium is configured to control a diffusion rate of a scent from the scent medium, and a shape of the scent medium remains constant in different environmental conditions. At least a portion of the body is transparent or translucent.

A smell generation time predicting device is used for a vehicle air conditioner which includes an evaporator installed in an internal path of an air conditioner case and configured to, when the air conditioner is turned on, cool air blown into a vehicle room. The device includes a first temperature detector, a second temperature detector, and a control unit. The first temperature detector and the second temperature detector are installed at a downstream side of the evaporator in a mutually spaced-apart relationship. The control unit is configured to, when the air conditioner is turned off, predict a smell generation time in the evaporator depending on a temperature difference between the air temperatures detected by the first temperature detector and the second temperature detector.

An air freshener having a barrier for controlled release of fragrance is disclosed having a body having a top portion, a middle portion, and a bottom portion, an amount of fragrance loaded on the body, and a barrier positioned over a portion of the body.
