Patent number: 8326534Abstract: 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 reference point, such as an originating point. The trajectory may be continuously or periodically updated. Applications may include various displays presenting images, numbers, pointers, paths, vectors, or data by digital screens, watch faces, or other devices integrated with or remote from the processor calculating the vector back to the point of origin.Type: GrantFiled: August 25, 2011Date of Patent: December 4, 2012Inventor: Phillip M.

Patent number: 7038770Abstract: A virtual-tight-wire system is provided for determining a centerline in a large rotary machine (10). The virtual-tight-wire system includes a columnar light source (30) that is positioned at one end of the rotary machine (10). A columnar beam of light (32) is emitted from the light source (30) toward light receivers (26) in a first and second centering tool (24). The beam of light (32) is adjusted to impact the center of the light receivers (26). Once the beam (32) has been aligned, the beam acts as a virtual tight-wire for identifying a centerline of the rotary machine (10).Type: GrantFiled: September 25, 2003Date of Patent: May 2, 2006Assignee: Siemens Power Generation, Inc.Inventors: Waheed A. Abbasi, Wilbert B. Rethage

Patent number: 6501536Abstract: A method and apparatus for use in locating the eyes of a vehicle driver or passenger in a vehicle for controlling vehicle systems including the positioning of vehicle sideview mirrors in relation to the driver's eyes to maximize the view of traffic on either side of the vehicle or the characteristics of vehicle airbag deployment. The location of a driver's or passenger's eyes is derived from the adjustment by the driver (or passenger, if capable of doing so) of adjustable light beam(s) emanating from light source(s) or illuminated indicia, until it (or they) intersect the driver's or passenger's eyes. From the angles of adjustment of the light beam(s) and other known coordinates of the vehicle, the location of the driver's or passenger's eyes or the target may be computationally derived as a set of Cartesian coordinates.Type: GrantFiled: January 22, 2001Date of Patent: December 31, 2002Inventor: Ronald J.

Patent number: 6453568Abstract: A laser protractor comprising two laser pointers fixed in a body to point exactly 90° apart in the same plane and a third laser pointer mounted on a movable arm rotatable about an axis perpendicular to the intersection of the first two laser pointers (as extended). The laser protractor includes leveling bubbles and degree scales on the body permitting the protractor to be accurately positioned with both fixed lasers in a horizontal plane, in a vertical plane or in any other plane as required. The laser protractor, because of its simple rugged construction, can be made inexpensively with simple off-the-shelf pointers, each battery powered with inexpensive batteries.Type: GrantFiled: November 19, 1999Date of Patent: September 24, 2002Inventor: Jeff Hymer

Patent number: 5088203Abstract: An eyeglasses measuring system comprises a fixed light source which projects a light beam onto two reflecting mirrors. The reflecting mirrors split the light beam into two separate light beams. One of the beams is positioned so that it tangentially illuminates the patient's cornea. A target mirror is then moved, by turning an adjustment screw. This adjustment positions the projection path of the second light beam tangentially onto the front surface of the patient's eyeglasses. The distance between the two beams of light is then determined by reading a scale.Type: GrantFiled: June 17, 1991Date of Patent: February 18, 1992Inventor: Leonard E. Neiswander

Patent number: 4219939Abstract: The present invention relates to a method and device for carrying out a survey of the basal area of a forest stand and the distribution of the individual trees with respect to diameter classes.The device of the invention comprises a caliper combined with a relascope in such a way that a certain position of the caliper corresponds to a certain sighting-angle. Furthermore the device comprises a sight field located at an observation point. When practicing the method of the invention the tree to be measured is calipered. Then the sighting-angle of the relascope is compared to the sight field and by checking if the sight field is within the sighting-angle it is determined whether the measured tree is within its border line circle or not.Type: GrantFiled: July 19, 1978Date of Patent: September 2, 1980Inventor: Christer Turen

Patent number: 4057906Abstract: A portable navigational instrument has edge portions which are adjusted so that the instrument's orientation with respect to a vessel can be maintained constant in different positions within the vessel's wheelhouse. Bearings of objects are determined by a sighting arrangement which co-operates with a scale which is set in accordance with the vessel's steering compass bearing, corrected for deviation, whereby the need for a compass on the instrument is avoided. The sighting arrangement can comprise a single visible sight, and/or three such sights enabling horizontal angles between objects to be determined from a further scale, and/or a radio direction finding aerial.Type: GrantFiled: January 23, 1976Date of Patent: November 15, 1977Inventor: Richard Creighton King
