摘要:
A method of detecting contaminants on a window surface of a viewing system comprises the steps of: reflecting light off of contaminants on the window surface; capturing the reflected light in an image; converting the image into image data; and processing the image data to detect the contaminants on the window surface. Also, apparatus for detecting contaminants on an external surface of a window of a viewing system comprises: at least one light source for reflecting light from contaminants on the external surface; an imager for capturing an image of the reflected light and converting the image into image data; and a processor for processing the image data to detect the contaminants on the external surface. The apparatus may be embodied in a viewing system wherein the imager also captures images of a scene of the viewing system both including the light reflected from the contaminants and not including light reflected from contaminants; and the processor processes both of image data of the scene excluding reflected light from the contaminants, and image data of the scene including reflected light from the contaminants to detect the contaminants on the external surface.

A lighting system includes at least one light emitting diode and a coating of matrix material having at least one glass-coated quantum dot in a base material. The at least one glass-coated quantum dot may be selected from at least one of a group II-VI materials, III-V materials, IV-VI materials, I-III-VI materials and combinations of such materials. The matrix material may be silicone, and the lighting system may include a light bulb replacement fixture including a threaded screw electrically connected to the light emitting diode.

A nesting chair includes a self-supporting base with a pair of leg members. Each leg member has a front leg portion, a rear leg portion, and a generally horizontal portion. A transverse member extends between and interconnects the horizontal portions of the leg members. The transverse member and the first and second leg members together define a self-supporting base. A seat cushion is supported in a generally horizontal position by the seat base. A generally L-shaped back support bracket has one end connected to the transverse member of the base and a second end connected to a seat back.
