Method and system for measuring a relative position and orientation of range cameras using a movement of an object within a scene. In general, the method and system determine the relative pose between two cameras by measuring a path the movement of the object makes within a scene and calculating transformation parameters based on these measurements. These transformation parameters are used to determine the relative position of each camera with respect to a base camera. The system and method incl...

A relative humidity detector, is formed upon a substrate such as glass or amorphous quartz. An aluminum layer evaporated onto the substrate has a layer of Al.sub.2 O.sub.3 anodized thereover to a thickness of 5,000 to 10,000 angstroms. A gold upper metallic layer overlies an adherent layer of chromium upon the Al.sub.2 O.sub.3 to a combined thickness of 1000 Angstroms. After the substrate has been mounted onto an appropriate header, it is submerged in a water bath for about 8 to 12 hours. It is ...

A relative positioning system enabling a user to return to a starting position or some other point on the user's path. The system may include an array of accelerometers. The output from the accelerometers may be integrated to quantify movement of the array. The various movements of the array may be reconstructed to determine a net two or three dimensional translation. The current location of the array may be compared to a reference point to derive at trajectory directing the user to the referenc...

Systems and methods for providing relative tracking for a user in an unprepared environment, e.g., in the field. A larger mobile unit, such as a truck, is tracked precisely in world coordinates using GPS and/or other tracking technology. A smaller mobile object or unit is then tracked with respect to the larger mobile unit. The tracking information of the smaller mobile object or unit is then combined with the tracking of the larger mobile unit such that the tracking of the smaller mobile object...

Calibrating the dose response of an image acquisition device comprises comparing a first self-calibration curve to a second self-calibration curve to determine the relationship between the curves; modifying an acquired image based on the at least one difference; and applying an initial calibration to the acquired image, whereby the dose response of the image acquisition device is calibrated.

Relatively quality value is described. In an implementation, a method includes calculating a mean success rate for a plurality of products utilized by a plurality of clients. For each of the products, a degree is determined, to which, either a first set of the clients or a second set of the clients predominate. The first set of clients have a success rate that is greater than or equal to the mean success rate and the second set of clients have a success rate that is less than or equal to the mea...

The invention relates to a digital sensor of relative position, which has a circular multipolar magnetic ring which is mobile in rotation opposite a stationary magnetic sensor comprised of at least two sensitive elements, respectively positioned facing a main track and a "revolution tick" reference track, and a device for processing of the output signals, such that on the magnetic ring, a magnetic pattern is produced from a pair of north and south poles whose transition is different from the tra...

A device for regulating the relative humidity of a closed chamber includes a layer of material capable of being impregnated with liquid and of adsorbing or desorbing vapor of the liquid. The material has on one of its surfaces a membrane which is permeable to vapor but not to liquid. The membrane having an outer surface which is hydrophobic. The adsorbent/desorbent material can be arranged in a sealed tank with an opening for filling with liquid. The device is especially suitable for a paint pal...
