    摘要: A method and apparatus for controlling weeds using concentrated solar energy is disclosed. Solar energy may be concentrated by Fresnel lens and directed by manual or automated methods at surfaces of weed plants to heat portions thereof causing damage. Shutters or other devices may be used to direct, and control intensity of concentrated, solar energy, such control preferably applied before significant concentration. In some embodiments, solar energy concentration apparatus may be integrated with ground, air, or water vehicles which may use solar photovoltaic cells for electric power for propulsion and other purposes. Vehicles may use global positioning satellite (GPS) receivers or other methods and apparatus, including video cameras, for navigation and selection of areas (e.g., row middles), plants, or portions of plants to be exposed to concentrated solar energy. Air vehicles may use hydrogen gas electrolyzed from water condensed from humid air to replenish hydrogen gas lost from containment vessels.

    摘要: Methods and systems are provided that control devices using signals transmitted over power lines in many different applications and configurations. They provide a lower cost approach for controlling devices via signals transmitted over power lines. The methods and systems may control intensity, spectral, and other characteristics of lighting devices, such as light-emitting diodes (LEDs) or assemblies thereof, via power lines. They may also control other types of loads, such as motors, relays, valves or the like. Additionally, techniques for independently controlling intensity and spectral content of selected high efficiency lighting devices are also described. For example, the brightness and color of an LED may be controlled via the power lines that supply power to the LED.

    摘要: Systems and methods are disclosed for determining location of a weapon firing incident. In one exemplary embodiment, there is provided a system for determining the location of a weapon firing incident in proximate position to a region traversed by vehicles. The system includes a first set of sensors associated with a first sub-region of the region, for detecting the weapon firing incident and for generating an output, and a processing component that determines a location of the weapon firing incident based upon the output. Moreover, the system may also include a second set of sensors arranged to detect the weapon firing incident along the travel path traversed by the vehicles and for generating a second output. Other exemplary embodiments may include arrangements of the sensors in patterns is associated with sub-regions and/or travel path as well as weapon fire location processing features.
