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.

Abstract: A training system provides workplace safety training. The training system includes one or more training mechanisms and a badge. The badge is operable to be registered with an employee and is operable to communicate with the training mechanisms. The training mechanisms are each operable to provide a training program to the employee. The badge is operable to receive progress of the employee for the training program from the training mechanisms, and the badge is operable to control access of the employee into an area of a jobsite based on the progress of the employee for the training program.

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. The controller receives an input from the user input device that is indicative of a selected heat profile of a plurality of heat profiles, and the controller controls the power output of the heater in accordance with the selected heat profile.
