A constant tension tether management system for tethered aircraft includes a ground station for operatively coupling to an unmanned aerial vehicle. The ground station includes a spool rotatably disposed within the ground station and adapted to support a tether thereon. A first pulley is rotatably mounted within the ground station along a tether travel path. A second pulley is rotatably disposed within the ground station and moves in translation along the tether travel path. The first pulley is disposed along the tether travel path between the spool and the second pulley.

Constant tension tether management system for a tethered aircraft

A system for landing an unmanned aerial vehicle has an unmanned aerial vehicle and a ground-based platform. A guide structure for receiving the unmanned aerial vehicle is mounted on the ground base platform. The guide structure has an inner diameter greater than a smallest outer diameter of the unmanned aerial vehicle landing gear and less than the largest outer diameter of the unmanned aerial vehicle landing gear.

Landing structure for an unmanned aerial vehicle

An unmanned aerial vehicle has a substrate. A tether sensor is mounted on the substrate. The tether sensor determines an orientation of the tether relative to the substrate. A micro controller, receiving the measured orientation from the tether sensor, determines an orientation of the tether relative to the substrate, and as a function of the orientation, determines a corrective value and outputs the corrective value to the unmanned aerial vehicle as at least one of a roll output and a pitch output control signal.

Tether orientation sensor for controlling the position of a tethered aircraft

A UAV has two rotors. First and second sensors sense a first and second type of input respectively. The second type of input is different than the first type, the first sensor providing a first sensor output and the second sensor providing a second sensor output. The first sensor output is input to a first computer and the second sensor output is input to a second computer. The first and second computer communicate in parallel to process the first and second sensor outputs to create a control signal having a predetermined number of variables therein, each variable having an exclusive position within the signal. The first computer outputs a first variable and the second computer outputs a second variable, each output being assigned an exclusive position within the control signal. At least one of the first and second computers outputting the control signal to the rotors.

An illumination system according to the principles of the invention may include a first LED and a carrier material. The carrier material may be comprised of plastic, synthetic material, polymer, latex, rubber or other material. The carrier material may also contain a phosphor, fluorescent material, organic fluorescent material, inorganic fluorescent material, impregnated phosphor, phosphor particles, phosphor material, YAG:Ce phosphor, or other material for converting electromagnetic radiation into illumination or visible light.

Systems and methods for converting illumination

Methods and apparatus for generating and modulating white light illumination conditions. Examples of applications in which such methods and apparatus may be implemented include retail environments (e.g., food, clothing, jewelry, paint, furniture, fabrics, etc.) or service environments (e.g., cosmetics, hair and beauty salons and spas, photography, etc.) where visible aspects of the products/services being offered are significant in attracting sales of the products/services. Other applications include theatre and cinema, medical and dental implementations, as well as vehicle-based (automotive) implementations. In another example, a personal grooming apparatus includes one or more light sources disposed in proximity to a mirror and configured to generate variable color light, including essentially white light, whose color temperature may be controlled by a user.

Methods and apparatus in which at least one first LED generates first radiation having a first spectrum, and at least one second LED generates second radiation having a second spectrum different than the first spectrum. One or more controllers control at least one of the first radiation and the second radiation so as to control at least a color temperature of visible radiation. In one example, one or more sensors monitor at least one characteristic of sample radiation and provide one or more sensor signals to the one or more controllers, which in turn control at least the color temperature of the visible radiation based at least in part on the at least one sensor signal. In various implementations, the sample radiation may be ambient illumination (e.g., natural-light and/or light from other light sources), may be the visible radiation itself (e.g., to provide feedback to the one or more controllers), or generally any desired lighting condition to simulate.
