Abstract
Implementations of a fluid flow sensing assembly may include a first shell coupled with a second shell including a central vane structure; a blade assembly rotatably coupled within the central vane structure, the blade assembly including one or more flags extending from a central hub; and a one or more fluid flow sensor elements coupled with the second shell of the flow sensor, the one or more fluid flow sensor elements configured to detect motion of the one or more flags where the assembly may be configured to be coupled with one or more scent diffusers.
Claims20
A fluid flow sensing assembly comprising:
- a first shell coupled with a second shell comprising a central vane structure;
- a blade assembly rotatably coupled within the central vane structure, the blade assembly comprising one or more flags extending from a central hub;
- and
- one or more fluid flow sensor elements coupled with the second shell of the flow sensor, the one or more fluid flow sensor elements configured to detect motion of the one or more flags;
- wherein the assembly is configured to be coupled with one or more scent diffusers.
A fluid flow sensing assembly comprising:
- a central vane structure coupled with a blade assembly comprising a blade axle;
- a hub coupled to the blade axle;
- one or more flags coupled with the hub;
- one or more fluid flow sensor elements positioned in the central vane structure configured to detect movement of the one or more flags;
- and
- one or more electrical connectors coupled with the central vane structure configured to be coupled with one or more scent diffusers.
A method of sensing fluid flow comprising:
- providing a fluid flow sensor comprising a central vane structure coupled with a blade assembly comprising a hub and one or more flags coupled with the hub, the central vane structure comprising one or more fluid flow sensor elements electrically coupled with at least one electrical connector comprised in the central vane structure;
- contacting the blade assembly with airflow causing the blade assembly to rotate;
- generating a corresponding electrical signal using the one or more flags of the hub and the one or more flow sensor elements and supplying the electrical signal to the at least one electrical connector;
- conveying the electrical signal from the at least one electrical connector to a scent diffuser;
- processing the generated signal with the scent diffuser using a processor to determine a state of the airflow;
- and
- in response to determining a state of the airflow, releasing a scent composition with the scent diffuser based on one or more predetermined thresholds associated with the state of the airflow.
