Abstract: A submersible pool vacuum system for powered debris collection from pool floors. The system includes a submersible powered vacuum assembly operatively connected to a buoyant power source via a buoyant-neutral umbilical tether for transmitting power. The vacuum assembly includes a motor and propeller for generating suction, a filtration media for debris collection, and multidirectional wheels for maneuverability thereof. The system includes a coupling handle for ergonomic retrieval and a pole for operator-controlled navigation from a pool deck. The buoyant power source includes a rechargeable battery and other systems for extended operation. A method of use thereof involving using the disclosed systems to collect and remove debris from pools.

Abstract: An unmanned visual monitoring system used outdoors to patrol large expanses of space such as along highways, fences, railroad lines, rivers, borders, beaches, etc. Guidance and support for the unmanned surveillance camera carriage vehicle, as well as the electrical power for its operation, are provided to the carriage and camera by conductive track cables. Spaced superstructures having upright poles and a cantilever extension placed along the track system length act to vertically support the system above the ground. At a remote control center location from the carriage, an operator can control the movement of the vehicle and the operation of the video camera. Operational electrical power for moving the carriage and controlling the camera's movement are supplied via power lines connected at different polarities to the track cables of the track system.
