摘要:
A method and apparatus are provided for automatically assessing a resolution of an optical sensor. An image is obtained from the sensor. The obtained image is thresholded to generate a binary image of black and white pixels using a first threshold value. A target area is selected from the binary image. The first threshold value is increased to generate a second threshold value. The target is thresholded using the second threshold value. At least one pixel is tagged at a center of the target area. Pixels surrounding a tagged pixel are processed, tagging white pixels. If a tagged pixel is at an edge of the target area, an orientation of an object in the target area is determined based on that edge. And, if no pixel is tagged at the edge of the target area, the second threshold value is decreased and the thresholding, tagging, and processing steps are repeated.

摘要:
A method for making an artificial hair sensor, comprising the steps of: (a) depositing an electrode at each end of a microcapillary having an inside surface; (b) coating a structural fiber with alumina; (c) placing the alumina coated structural fiber inside the microcapillary, wherein part of the alumina coated structural fiber is in a spaced annular relationship with the microcapillary inside surface and part of the fiber extends outside the microcapillary; (d) placing the microcapillary and alumina coated structural fiber inside a heated furnace chamber; and, (e) injecting a vaporized catalyst into the heated furnace chamber. The vaporized catalyst may be a solution of ferrocene in xylene. The microcapillary may be made of glass.

A surface can be coated with a liquid repellent coating. Materials for making the liquid repellent coating (e.g., a fingerprint resistant coating) can be selected on the basis of surface energy considerations, such as a receding surface energy. The materials can include a polymer and a liquid repelling material, for example, poly(ethyl methacrylate) and a fluorinated silsesquioxane such as fluorodecyl POSS.

Apparatus and method improving the performance and allowing increased directionality and bandwidth via display-like software defined antenna. A surface is composed of an array of interconnected pixels which are capable of either becoming conducting or resistive allowing arbitrarily sized and shaped antenna structures. Each pixel is controlled by biasing the base which alters the conductivity on the top portion of the pixel. The specific pattern which is active on the display style antenna is based on the desired direction, frequency range, and waveform necessary for a required transmit and receive function.

A method of forming perovskite thin films with micron-sized perovskite grains is provided. A layer of PbX2 in a solution containing a metal ion additive is applied to a structure. The structure with the PbX2 layer is annealed a first time. The PbX2 is exposed to CH3NH3X in a solvent. The structure with the exposed PbX2 layer is annealed a second time resulting in a CH3NH3PbX3 layer. X is selected from a group consisting of Cl, Br, I, CN, and SCN.

A system for automating the control of a Remotely Piloted Vehicle (RPV) includes a computer having a processor and a memory, a display operatively coupled to the computer and configured to display a future operating condition of the RPV and an input device operatively coupled to the computer. A predicted noodle tool is executed by the processor and configured to indicate a predicted future path of the RPV by generating a predicted noodle segment on the display. A directed noodle tool is executed by the processor to indicate a pilot-adjustable proposed future flight path of the RPV by generating a directed noodle segment on the display. Further, an input device mode selector is operatively coupled to the processor and configured to selectively map the input device to either manipulate a control surface of the RPV, or to manipulate the directed noodle segment.
