Abstract: A fragrance dispenser can comprise a housing having a socket portion and defining a receptacle configured to receive a bottle having a fragrance-producing liquid therein and a wick extending therefrom. A heater can be disposed proximate to the receptacle so that, when the bottle is received within the receptacle, the heater is disposed proximate to the wick. A controller can be configured to deliver electrical voltage (e.g., pulse-width-modulated voltage) to the heater. A user input device can be in communication with the controller.

Abstract: A coupling mechanism is provided for coupling a vehicle with a payload. A latch mechanism includes a spring-loaded latch. The spring-loaded latch can be operable to transition between a locked configuration and an unlocked configuration. A tension connection can be operable to hold the latch mechanism under a tension force. When the payload receives a release force, the spring-loaded latch transitions to the unlocked configuration such that the payload is releasable from the vehicle.

Abstract: In at least one aspect, a computer-implemented method includes: accessing, by an agricultural management system, first data from an operational database; accessing, by the agricultural management system, second data from a real-time data server; determining a metric based on the first data and the second data; generating a first graphical user interface (GUI) for display on a client device, where the first GUI includes at least one data visualization based on the metric; and adjusting, by the agricultural management system, a setting of a piece of equipment.

Abstract: An access control system is provided with an access control structure. The access control structure is operable to control access to a zone. A housing forms one or more through paths, and a dividing wall received in the housing is configured such that each through path is non-linear.

Abstract: A modular system for drones is provided. A chassis can include a coupling mechanism operable to removably couple the chassis with a drone. A plurality of modular components can be operable to be interchangeably coupled with a control component. The modular components can be operable to be detachably coupled with a payload.
