摘要:
A method of increasing the area of carbon nanotubes used in fabricating capacitors is described. The method involves reacting carbon nanotubes with electrically conductive ions, molecules or nanoparticles that increase the surface area of the nanotubes. The capacitance and the energy stored in the capacitor can be increased by such treatment. Devices constructed from such treated materials and their properties are described.
摘要:
The subject system hardware and methodology combine disparate cameras into a cohesive gesture recognition environment. To render an intended computer, gaming, display, etc. control function, two or more cameras with non-coaxial axes are trained on a space to detect and lock onto an object image regardless of its depth coordinate. Each camera captures one 2D view of the gesture and the plurality of 2D gestures are combined to infer the 3D input.

A camera has a lens and aperture device for determining 3D information. A projector projects an optical pattern toward a surface. The camera has at least two off-axis apertures thereon, arranged to obtain an image of the projected pattern including defocused information. The camera is movable between different positions to image the surface from said different positions, and the projector is at a specified angle of at least 5° relative to said camera. A processor carries out a first operation using information received through the apertures to determine a pose of said camera, and to determine three dimensional information about the object based on a degree of deformation of said optical pattern on said surface indicative of a three dimensional surface. An embodiment projects a grid of laser dots and uses laser-dot defocusing for approximate Z and thus grid correspondence, which can greatly increase the working depth of the system.

摘要:
Described is a method and apparatus for obtaining additional information from an object and a method for surface imaging and three-dimensional imaging. Single lens, single aperture, single sensor system and stereo optic systems may be modified in order to successfully generate surface maps of objects or three-dimensional representations of target objects. A variety of the aspects of the present invention provide examples of the use of an addressable pattern in order to overcome mismatching common to standard defocusing techniques.
