A harvesting system includes at least one modular unit coupled to a harvester includes a drying unit to dry a harvested material introduced into the harvester including at least one rotating drum, a number of appendages extending from the at least one rotating drum, at least one sensor to determine at least one environmental state within the drying unit, and at least one environmental state adjustment device to adjust at least one environmental attribute within the drying unit. The modular unit also includes a collection unit to collect the harvested material into a unit, a first conveyor mechanism to convey the harvested material from the drying unit to the collection unit, and a control system to control at least the harvester, the drying unit, the collection unit, the first conveyor mechanism, the sensor, and the environmental state adjustment device based on a signal received from the at least one sensor.

A network of modular, multitier pool mobile units, that wander around and under water of a swimming pool. The pool mobile units monitor for safety, emergency and accident related events and undertake appropriate actions to provide care and protection for swimmers, family members and bystanders. They scrub and clean the swimming pool bottom and wall surfaces and emit chemical agents to sanitize the swimming pool water. A central server provides safety monitoring help for drowning swimmers, and emergency and accident supports.

A stalk puller to be used with or without a mower/shredder utilizes a pair of independently mounted discs converging along their lower edge to grasp and pull stalks from the ground as the stalk puller is moved down the row by a prime mover. At least one of the discs is urged against the other by a spring such that the associated disc may allow rocks and debris to pass between the discs without damage. The spring mounting reduces adjustments due to normal wear as well as damage from debris.

An example harvester that may include a weed seed devitalizer and a controller that automatically adapts or adjusts the weed seed devitalizer. The controller is to receive data from at least one sensor indicating forthcoming weed seeds and to output control signals controlling the weed seed devitalizer based on the data.

A network of modular, multitier pool mobile units, that wander around and under water of a swimming pool. The pool mobile units monitor for safety, emergency and accident related events and undertakes appropriate actions, scrub and clean the swimming pool, emit chemical agents to sanitize the swimming pool water, and may play music. The pool mobile units may simply operate on the pool surface, be fully submersible, or semisubmersible. A central server manages a plurality of multitier pool mobile units in a plurality of swimming pools, supports music download, and provides experience based resources for the multitier pool mobile units. The central server provides experience based resources in the form of safety, emergency and accident supports. The user can configure the parameters of both pool mobile unit and the central server.
