2592 results about "Sky" patented technology

The sky (or celestial dome) is everything that lies above the surface of the Earth, including the atmosphere and outer space. In the field of astronomy, the sky is also called the celestial sphere. This is an abstract sphere, centred on the earth, on which the Sun, stars, planets, and Moon appear to be traveling. The celestial sphere is conventionally divided into designated areas called constellations. Usually, the term sky is used informally as the point of view from the Earth's surface; however, the meaning and usage can vary. An observer on the surface of the earth can see a small part of the sky, which appears to be a dome, also known as the sky bowl, flatter during the day than at night. In some cases, such as in discussing the weather, the sky refers to only the lower, more dense portions of the atmosphere.

Weather-responsive shade control system

An automatic daylighting method adjusts a window covering to block direct sunlight from entering the room through a window when the exterior sky condition is a sunny sky state and, subject to blocking direct sunlight, provides a desired daylighting interior light illuminance level and, if possible, a desired interior solar heat gain through the window. To prevent window covering oscillation, a delay may be used when the sky condition changes from a sunny to overcast state. The covering control may be based on various factors including interior light illuminance entering the window, a room heating or to cooling mode, whether the room is occupied by people, whether occupants have manually operated an adjustable window covering, and the exterior sky condition. The method may also detect an interior temperature level, e.g., to determine a heating or cooling mode of the room.

In a first set of preferred embodiments three relatively large aperture telescopes are rigidly mounted on a movable platform such as a ship or airplane with each telescope being directed at a substantially different portion of sky. Embodiments in this first set tend to be relatively large and heavy, such as about one cubic meter and about 60 pounds. In a second set of preferred embodiments one or more smaller aperture telescopes are pivotably mounted on a movable platform such as a ship, airplane or missile so that the telescope or telescopes can be pivoted to point toward specific regions of the sky. Embodiments of this second set are mechanically more complicated than those of the first set, but are much smaller and lighter and are especially useful for guidance of aircraft and missiles. Telescope optics focus (on to a pixel array of a sensor) H-band or K-band light from one or more stars in the field of view of each telescope. Each system also includes an inclinometer, an accurate timing device and a computer processor having access to catalogued infrared star charts. The processor for each system is programmed with special algorithms to use image data from the infrared sensors, inclination information from the inclinometer, time information from the timing device and the catalogued star charts information to determine positions of the platform. Direction information from two stars is needed for locating the platform with respect to the celestial sphere. The computer is also preferably programmed to use this celestial position information to calculate latitude and longitude which may be displayed on a display device such as a monitor or used by a guidance control system. These embodiments are jam proof and insensitive to radio frequency interference. These systems provide efficient alternatives to GPS when GPS is unavailable and can be used for periodic augmentation of inertial navigation systems.

Satellite downlink via patterns of uncollimated light

A satellite or spacecraft in low Earth orbit, when in eclipse and not illuminated by sunlight, represents a low-bandwidth datastream through modulation of a source of uncollimated light, such as a set of light emitting diodes. Transmission modes include generating patterns in the color, intensity or polarization of a light source, or precise timing control of a strobe signal. A ground station tracks the satellite in a telescope, stewing the telescope to follow the satellite as it moves across the sky, recording light generated by the satellite with a light sensor such as a video camera. The datastream is regenerated through analysis of recorded video. Satellite downlink is initiated by detection of eclipse, by command via radio uplink, or in response to a periodic automatic timer. In an alternative embodiment, the satellite represents the datastream through modulation of its effective albedo or reflective flux during periods of solar illumination.

Infrared images method for detecting targets at sea

The invention provides an infrared images method for detecting targets at sea, which relates to a method for detecting the targets at sea. The invention aims to provide the method for detecting the targets at sea, which not only can well inhibit sea clutters to obtain reasonable image segmentations, but also can extract out the fractal characteristics at a high speed to remove false targets so as to achieve effective detections. The method comprises the following steps: performing preprocessing on the obtained infrared images; performing self-adapting iteration threshold segmentation; detecting whether the part of a sea-sky line has a region of interest (ROI); extracting the ROI at the background part of the sea-sky line; extracting the ROI at the background part of a non-sea-sky line; and combining the regions of interest to obtain an image of interest to be further processed, and extracting the fractal characteristics of each ROI to perform target detections. The method can quickly and effectively segment out the regions of interest in the infrared images, and not only reduces the amount of calculation to extract out the fractal characteristics at a higher speed because the extracted regions of interest is far smaller than the original images, but also can remove the false targets appearing in the threshold segmentation through the fractal characteristics.

Use of self and neighboring vehicle gps/gnss data to estimate current and approaching sky visibility changes

A method and system for creating a sky visibility map, using data from a vehicle and its neighbors. A host vehicle with satellite-based navigation capability measures the quality of signals it receives from available satellites, where azimuth and elevation angles of the satellites are known from an ephemeris or almanac. The host vehicle also receives satellite signal data from surrounding vehicles via vehicle-to-vehicle communication. Using data from all of the vehicles, a sky visibility map is constructed, indicating where obstructions to satellite visibility exist for different locations. The sky visibility map is used to anticipate satellite signal quality. A driving environment classification can be used to configure other vehicle systems. The sky visibility map can also be constructed without using data from surrounding vehicles; the host vehicle can store its satellite signal data long-term and use it to estimate satellite visibility when returning to a location previously visited.
