    Abstract: A method and system for measurement of ground based vehicle speed includes a movable platform that includes an unmanned aerial vehicle (UAV) located in proximity to a roadway, the UAV operates under control and navigation of a UAV control unit, and the UAV also carries camera and monitoring equipment, the camera and monitoring equipment including an onboard computing system, and a camera with a wide angle lens and a camera with a telephoto lens, the cameras being mounted on a pan/tilt device. An algorithm operated by the on-board computing system is used to detect and track vehicles moving on a roadway. The algorithm is configured to detect and track the vehicles despite motion created by movement of the UAV. The cameras mounted on the pan/tilt device are moved under the direction of the computer vision algorithm to maintain a target vehicle of the detected moving vehicles in view, and the speed of the target vehicle is measured.

    Abstract: A device includes at least one stress-engineered portion and at least one second portion. The stress-engineered portion includes at least one tensile stress layer having a residual tensile stress and at least one compressive stress layer having a residual compressive stress. The tensile stress layer and the compressive stress layer are mechanically coupled such that the at least one tensile stress layer and the at least one compressive stress layer are self-equilibrating. The stress-engineered portion is configured to fracture due to propagating cracks generated in response to energy applied to the stress-engineered portion. Fracture of the stress-engineered portion changes functionality of the device from a first function to a second function, different from the first function.

    Abstract: A light emitting diode (LED) light bulb includes a thermally conductive base and at least one LED assembly disposed on and thermally coupled to a surface of the base. The LED assembly includes at least one LED configured to generate light. A thermal optical diffuser defines an interior volume and the LED is arranged to emit light into the interior volume and through the thermal optical diffuser. The thermal optical diffuser is disposed on the surface of the base and extends from the base to a terminus on the light emitting side. The thermal optical diffuser is configured to include one or more openings that allow convective air flow between the interior volume of the thermal optical diffuser and ambient environment.

    Abstract: Methods of leveling ink on substrates and apparatuses useful in printing are provided. An exemplary embodiment of the methods includes irradiating ink disposed on a surface of a porous substrate with radiation emitted by at least one radiant energy source. The radiation heats the ink to at least a viscosity threshold temperature of the ink to allow the ink to flow laterally on the surface to produce leveling of the ink. The ink is heated sufficiently rapidly that heat transfer from the ink to the substrate is sufficiently small during the leveling that ink at the substrate interface is cooled to a temperature below the viscosity threshold temperature thereby preventing any significant ink permeation into the substrate.
