Patent number: 7051447Abstract: Methods and systems for realizing accurate coordinate measurement using a multi-joint measuring arm. A system includes a support member, a multi-joint measuring arm having a first end attached to the support member and a second end at which a probe can be installed, and a processor configured to produce a three-dimensional coordinate corresponding to a position of the probe based on an angle of each joint of the measuring arm. A parameter concerning a posture of the measuring arm is detected exceeding a prescribed value, and a user is warned in accordance with a result of the detection. The prescribed value has been determined, for example, in accordance with a probability that a measurement error due to a user action pulling the measuring arm away from the support member becomes out of an allowable range.Type: GrantFiled: February 26, 2004Date of Patent: May 30, 2006Assignee: Kosaka Laboratory Ltd.Inventors: Akira Kikuchi, Kenji Araki, Katsumi Oshiro

Patent number: 7010862Abstract: Celestial object location devices with sensor arrays of having less that one sensor for each of three orthogonal components of gravity and magnetic field vectors. The accuracy of position sensing is enhanced by estimating “missing” sensor input based on input from two orthogonal sensors provided, or determined with limitations from the two gravitational sensors provided.Type: GrantFiled: June 4, 2004Date of Patent: March 14, 2006Assignee: Yamcon, Inc.Inventors: Michael Lemp, III, Michael Hatalski

Patent number: 6988321Abstract: An electrostatic capacitance tilt angle sensor having a size that is reduced without lowering detection capacity. The sensor is provided with a case including a first wall and a second wall facing each other. A common electrode is arranged on the first wall and a differential electrode is arranged on the second wall. A liquid electrostatic capacitance medium is accommodated in the case and contacts the common electrode and the differential electrode. The electrostatic capacitance medium includes an insulative liquid base and fine particles mixed in the base. The fine particles have a dielectric constant that is higher than that of the base.Type: GrantFiled: October 28, 2004Date of Patent: January 24, 2006Assignees: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Hiroshi Ueno, Tadashi Hattori

Patent number: 6987460Abstract: Disclosed is an orientation device that may be deployed in a mechanical assembly such as a surveillance camera or enclosure to positively determine the physical orientation and/or attitude (tilt), or any change in such physical orientation and/or attitude, of either the camera or the enclosure, and report that information electronically. The invention includes a sensor that is triggered by the movement of a weighted flag along a shaft caused by gravity or gravity in conjunction with the operation of a spring. As the invention is rotated through 360°, the force of gravity and force of the spring are exerted on the weighted flag, causing it to move along the shaft as the assembly is rotated. Each movement by the flag is detected by the sensor which sends an electronic signal indicating that a predetermined point has been reached. Multiple assemblies may be used, offset from each other, to provide additional and more precise position information.Type: GrantFiled: March 14, 2003Date of Patent: January 17, 2006Assignee: PelcoInventors: Erik H. Tews, Alex Pokrovsky, Thomas C. Lyon

Patent number: 6981333Abstract: An ergonomically equipped and interference signal-reducing position measurement probe for mutual alignment of bodies has a speech input device and/or a speech output device. The probe is wirelessly linked to an external control or a higher-level supervisory computer either by an infrared interface or a radio link which operates at an extremely high frequency. Error-reducing measured value acquisition is effected by averaging. The average represents several individual measured value. In the acquisition of the individual measured values, it is watched that the times of measured value recording and the time peaks of a solid-borne sound oscillation on the measurement object are essentially asynchronous to one another.Type: GrantFiled: December 5, 2000Date of Patent: January 3, 2006Assignee: Pruftechnik Dieter Busch AGInventor: Dieter Busch

Patent number: 6886287Abstract: A rifle scope system allows adjustment of the scope while a shooter maintains the shooting posture and the scope sight picture. The scope system comprises an adjustment system comprising an electromechanical mechanism that responds to a signal from a remote controller manipulated by the shooter without having to significantly disturb the shooting posture. The adjustment system allows the shooter to adjust the scope's point of aim to coincide with a bullet's point of impact at a target. Such adjustment can be performed either by the shooter. Alternatively, such adjustment could be performed by a processor configured to adjust the point of aim based on a ballistic parameter associated with the bullet or the shooting environment. The adjustment system allows such processor-determined adjustments to be effected in a quick manner.Type: GrantFiled: May 19, 2003Date of Patent: May 3, 2005Inventors: John Curtis Bell, Kendall Seidel
