Abstract: The system for validating the use of an activity area comprises an activity area having at least one activity detector adapted for collecting activity data. A computer is configured for determining, based on the activity data, an activity level in one or more zones in said activity area, comparing the activity level in said one or more zones onto a known mapping of said activity area, and determining whether the activity level in said one of more zones is above a predetermined activity value based on said known mapping.

Abstract: A system and method for measuring a payload including a surface, the system comprising a sensor and a processor. The sensor is configured to generate a signal constituting data representing an unobstructed portion of the surface and an obstacle obscuring a portion of the surface. The processor is communicatively coupled to the sensor and is configured to identify data points in the data corresponding to the unobstructed portion of the surface, identify data points in the data corresponding to the obstacle, interpolate between some of the data points corresponding to the unobstructed surface adjacent the data points corresponding to the obstacle, generate interpolation data points corresponding to the portion of the surface obscured by the obstacle, and determine a volume of the payload based on the data points corresponding to the unobstructed portion of the surface and the interpolation data points.
