Abstract: A system for measuring crop weight in a harvester elevator includes a receiver and processing node and one or more weight sensing instruments coupled to one or more paddles of the harvested elevator, respectively. The weight sensing instruments each include a weight sensor and a transmitter in communication with a receiver and processing node. The weight sensor is configured to dynamically measure the weight of a static harvested crop, relative to the sensor and corresponding paddle, at ascends in the harvester elevator.

Abstract: Methods and apparatuses for providing wide-area surveillance with a radar and/or other sensors from a stratospheric balloon launched from a land or ship platform for detection, tracking, and classification of maritime, land, and air objects such as ships, people/vehicles, or aircraft are described generally herein. In one or more embodiments, an apparatus is battery operated and includes a stratospheric balloon filled that is filled with helium when it is launched and a gondola with a radar system and communication equipment suspended therefrom. When launched, the apparatus can travel with the wind until it reaches an altitude of approximately 68,500 ft., then it can move substantially horizontally with the stratospheric winds until it returns to earth via a parachute. Multiple apparatus launches at periodic intervals can help provide continuous coverage of the surveillance area. The apparatus can be recovered and re-used or can be considered expendable.
