Abstract: Certain embodiments of the present application relate to a method for releasing a parcel from an unmanned aerial vehicle (UAV). The parcel is engaged with a hook attached to a line suspended from the UAV. The method includes lowering the hook such that the parcel is at least partially supported by a target surface, thereby performing an attempt to release the parcel from the hook, performing at least one iteration of an iterative procedure. The iterative procedure includes raising the hook, and determining whether the line remains loaded. The iterative procedure further includes lowering the hook an additional time in response to a determination that the line remains loaded, thereby performing an additional attempt to release the parcel from the hook. The iterative procedure further includes performing an additional iteration of the iterative procedure in response to the number of attempts failing to satisfy a threshold number of attempts.

Abstract: A method of detecting an event and recording quantitative parameters associated with the event is provided. The method includes securing an event detection and recording system on a piece of equipment, the event detection and recording system comprising a plurality of sensors, an internal power source, and a microcontroller. The method further includes activating a low monitoring mode and measuring one or more quantitative parameters with the one or more of the sensors at a first sampling rate to generate low monitoring mode sensor data; analyzing the low monitoring mode sensor data to detect initiation of a triggering event; terminating the low monitoring mode upon detection of the triggering event; and activating a high monitoring mode including measuring and recording one or more quantitative parameters at a second sampling rate, where the second sampling rate is greater than the first sampling rate. The associated system is also provided.
