Patent number: 8431841Abstract: A rangefinder, for locating an object moving parallel to a planar surface, is rigidly attached to a carrier that is pivotably movable between an obverse position and a reverse position relative to a planar surface. Preferably, an orienting mechanism is provided for determining which position, obverse or reverse, the carrier and rangefinder are in. Preferably, a pivot, for pivoting the carrier and the rangefinder between the two positions, is rigidly attached either to the plane surface or to an attachment mechanism for reversibly attaching the carrier to the planar surface.Type: GrantFiled: January 29, 2009Date of Patent: April 30, 2013Assignee: Pegasus Technologies Ltd.Inventors: Gideon Shenholz, Isaac Zloter

Publication number: 20100220078Abstract: A system 5 for tracking the position of a digital 100 pen including a (i) pen-fixed ultrasound device 210 (i.e. transmitter or receiver) and (ii) a plurality of writing-surface fixed ultrasound devices 150 (i.e. transmitters or receivers) is disclosed. In some embodiments, a measurement is made of the time that it takes for ultra-sound to travel between the pen-fixed ultrasound device 210 and the writing-surface fixed ultrasound devices 150 via a path that includes a writing surface sub-path 170 between the ‘given point’ 175 on the writing surface and the writing-surface fixed ultrasound devices 150. In some embodiments, the position of the digital pen 100 or a component thereof (for example, pen-fixed ultrasound device 210) may be determined in accordance with (i) the aforementioned measured times of ultra-sound travel; and (ii) the speed of sound within the writing surface 140. Related methods for tracking the position of the digital pen 100 are disclosed.Type: ApplicationFiled: October 7, 2007Publication date: September 2, 2010Applicant: PEGASUS TECHNOLOGIES LTD.Inventors: Isaac Zloter, Gideon Shenholz

Patent number: 6424340Abstract: A presentation board digitizer system for large boards preferably employs at least three spaced-apart ultrasound receivers assemblies. A current position of an ultrasound transmitter is assigned as a weighted centroid of time-of-flight position measurements based on at least two pairs of receiver assemblies. The weighting used varies as a function of the transmitter across the board. A preferred structure of an ultrasound receiver assembly for use in the system employs a pair of ultrasound receivers arranged side-by-side in a line perpendicular to the surface of the presentation board. The receives are connected so as to generate a total output signal corresponding to the instantaneous sum of the ultrasound signals received at each, such that the receiver assembly is most sensitive to ultrasound signals incident from a plane adjacent to the presentation board.Type: GrantFiled: July 26, 2001Date of Patent: July 23, 2002Assignee: Tidenet, Inc.Inventors: Rafi Holtzman, Isaac Zloter

Patent number: 6326565Abstract: A transmitter device is disclosed for use with a conventional pen in which the ultrasound transmitter is a cylindrical element lying coaxial with the pen and adjacent to its tip, and a jointed eraser structure. Conventional triangulation techniques are used to track the position and motion of a writer or eraser. An encoding facility associated with the pen provides the ability to distinguish whether the pen is used for marking or an as erasing implement, as well as determining the nature or character of written line width or eraser swath. A data stream thus generated can be used in a variety of ways, such as for example, to feed information into the memory of a digital computer, and/or to feed information for transmission to remote stations.Type: GrantFiled: February 28, 1997Date of Patent: December 4, 2001Assignee: Electronics for Imaging, Inc.Inventors: Rafi Holtzman, Isaac Zloter
