Abstract
Abstract A system for aerating in a programmed manner the desired areas of a water pond to enhance the environment for marine life in the pond; said system including a propelled boat with an aerator mounted thereon and having direction control apparatus including a rotating beam-sending component, a plurality of beam-reflecting posts located in predetermined fixed relationship around the shore line of the pond, and a beam-receiving component mounted on the boat to receive the beam reflected back from each of the reflecting posts, whereby the position of the boat can be determined automatically by angle determining components combined with a microprocessor programmed to calculate by triangulation computation the position of the boat and produce a signal which is connected to a servo system which controls the direction of travel of the boat in its aerating path around the pond.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
209 words
An aerating system for aerating substantially all areas of a pond of water surrounded by a bordering shoreline, said system comprising: a self-propelled flotation unit, a subsurface aerating discharge nozzle mounted on said unit for discharging aeration gas into the water below the surface thereof, programmed means mounted on board the unit free from any connection with the shoreline for guiding and propelling the flotation on the water surface in a substantially predetermined path so that the aerating discharge for the nozzle effectively distributes the aerating gas to substantially all areas of the pond with complete freedom of controlled movement without restraints connected to the shoreline, said electronic control system comprising a sending, computing and automatic control of the direction and speed of the unit and which includes a laser beam timed transmitting device also mounted on the flotation unit combined with a plurality of reflecting mirrors mounted in fixed relation to the shore line of the pond to produce a flotation unit orienting signal, means on board the unit for sensing the orienting signal to determine the angular position of the flotation unit, said electronic control system automatically varying the direction of travel of said unit to be controlled in accordance with the sensed position of the unit.
Claim 2
Dependent Claim

An aerating system for aerating substantially all areas of a pond of water surrounded by a bordering shoreline, said system comprising: a self-propelled flotation unit, a subsurface aerating discharge nozzle mounted on said unit for discharging aeration gas into the water below the surface thereof, programmed means mounted on board the unit free from any connection with the shoreline for guiding and propelling the flotation on the water surface in a substantially predetermined path so that the aerating discharge for the nozzle effectively distributes the aerating gas to substantially all areas of the pond with complete freedom of controlled movement without restraints connected to the shoreline, said electronic control system comprising a sending, computing and automatic control of the direction and speed of the unit and which includes a laser beam timed transmitting device also mounted on the flotation unit combined with a plurality of reflecting mirrors mounted in fixed relation to the shore line of the pond to produce a flotation unit orienting signal, means on board the unit for sensing the orienting signal to determine the angular position of the flotation unit, said electronic control system automatically varying the direction of travel of said unit to be controlled in accordance with the sensed position of the unit.
Claim 3
Dependent Claim
64 words
The structure set forth in claim 1 which includes a plurality of fixed stationary reflector members for receiving and reflecting the laser beam transmitted from said flotation unit and means for rotating the laser beam transmitter through 360 degrees required orientation data for the electronic control system to constantly monitor the position of the flotation unit and guide the propulsion thereof around the pond.
Claim 4
Dependent Claim
33 words
The structure set forth in claim 1 and means mounted on said flotation unit for supplying energy for the laser beam transmitter, the propulsion power for the unit, and the directional control apparatus.
