    Abstract: A system and method include generating environment data from skylight sensor data. The environment data includes a value of a geospatially dependent parameter associated with light received from a predetermined celestial light source. At least two of a compass direction of the predetermined celestial light source when the skylight sensor data was received, a time at which the skylight sensor data was received, or a geospatial coordinate at which the skylight sensor data was collected are received. At least one of the compass direction of the predetermined celestial light source when the skylight sensor data was received, the time at which the skylight sensor data was received, or the geospatial coordinate at which the skylight sensor data was collected is determined, at least in part, from the environment data.

  • Publication number: 20120106170
    Abstract: A sight system is provided which may be selectively used in a variety of different ways. In one example, the sight system may be positioned on a rifle to provide a rifle sight system. In this example, the sight system may be positioned on the rifle barrel a substantial distance away from a user's eye. Advantageously, such an implementation may permit a user to effectively sight the rifle without compromising situational awareness. In another example, the sight system may be used to provide a telescopic sight with a reticle (e.g., a dot, crosshair, mark, or other appropriate shape) superimposed on an image (e.g., a zoomed or non-zoomed image) displayed from a camera. In another example, the sight system may be used to provide an occluded sight in which a camera and/or display of the sight system is disabled. As a result, a reticle may be displayed over an opaque background.

  • Patent number: 5124844
    Abstract: A method and an apparatus for locating in the sky celestial objects, using a telescope, wherein two guide stars and the celestial object are represented, according to their respective locations, on a disc which is able to rotate with respect to the telescope around an axis, orthogonal to the telescope axis, and passing through the representation of the celestial objects. The images of the two guide stars are projected in the sky and the telescope and the disc are moved until the images of the guide stars are superposed with the respective actual guide stars in the sky.The guide stars form a triangle with the celestial object. The telescope is preferably provided with a alt-azimuth type mounting. The guide stars are represented on the disc by small holes. A light source placed under the disc creates light dots which are projected in the sky using a plano convex lens optically aligned with the disc rotation axis, and a semi-transparent mirror inclined at 45 degrees on the rotation axis.

  • Patent number: 4360256
    Abstract: A photographic or electronic camera optoelectronic distance measuring system has a lens with two partial aperture diaphragms which create first and second partial bundles of rays. Two linear image sensors are provided together with optical devices for projecting segments of lines corresponding to two images obtained from the object onto the image sensors. An evaluating circuit, in dependence upon varying position displacements of sensor signals obtained from the one image sensor with respect to the sensor signals obtained from the other image sensor, determines a maximum correlation between these and an associated position displacement. A device is provided for deflecting the ray path at least partially into a view finder. Two focusing lens parts are arranged in a region of an eyepiece of the view finder which locate partial aperture diaphragms of the lens by imaging in the plane of the view finder eyepiece.
