| 8081302 | Multimode optical sensor A Multimode Optical Sensor (MMOS) is a laser radar (ladar) that employs both coherent, or heterodyne, and noncoherent detection at long range, i.e. ranges for which the target is no more than a pixel in dimension. Coherent detection provides much higher velocity res... | 12/20/2011 |
| 6613441 | Boron- and/or aluminum-containing mixtures, hybrid materials, and coatings The present invention relates to mixtures prepared from (A) at least one linear, branched, or cyclic monomeric organosilane having at least two silicon atoms with hydrolyzable and/or condensation-crosslinking groups in which the silicon atoms are bonded to... | 09/02/2003 |
| 5298977 | Visual inspection method for part mounted on printed circuit board Three different color light beams which are converged to a single light spot on the surface of a circuit board at predetermined incident angles, are irradiated onto the top surface of an electronic part mounted on the circuit board, then distances between... | 03/29/1994 |
| 5039217 | Optical transceiver apparatus for detecting distance between two cars An apparatus for detecting the distance between one's car and the car ahead, together with the angle between the axes of the two cars. The apparatus has a pair of driving optical systems disposed at a predetermined distance from each other, each driving o... | 08/13/1991 |
| 4943149 | Telescope A bearing bush with a side opening is mounted within a telescope barrel. The telescope thus may be easily mounted on a tilting axis by simply inserting an axle into the bush. Mounting and adjustment of the tilting axis within its bearings and of angular m... | 07/24/1990 |
| 4697921 | Device for detecting a relative change in distance between two measuring points, and its use As is known, the walls in cavity structures often become quiescent only after a prolonged period. In order to detect whether and to what extent rock displacements can occur, measuring instruments are installed at mutually opposite points (I, II) on walls ... | 10/06/1987 |
