Patent number: 7800773Abstract: A client print server link is provided, which uses two-way communication between a client computer and a printing system typically comprised of networked output devices and print servers. The client print server link provides detailed information regarding each print server and connected device within a printing system. The client print server link allows a client user at a client computer to access information and control each of their print jobs quickly and efficiently within a single application, without requiring the user to access a plurality of separate utilities. The client print server link groups and displays information that is relevant to print jobs sent by a single client user to connected print servers and output peripheral devices.Type: GrantFiled: December 3, 2007Date of Patent: September 21, 2010Assignee: Electronics for Imaging, Inc.Inventors: Bradley S.

Patent number: 6501461Abstract: A graphic data-acquisition system which employs an active tracking system provides a retrofittable apparatus for converting a substantially planar surface into an electronic data capture device, in which the components of the system are readily retrofittable, at relatively low cost, to a wide variety of otherwise conventional writing-surface structures, such as so-called dry-erase whiteboards. Conventional triangulation techniques are used to track the position and motion of a writer or eraser. An encoding facility associated with the writing implement provides the ability to distinguish whether the writing implement 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: March 24, 1999Date of Patent: December 31, 2002Assignee: Tidenet, Inc.Inventor: Rafi Holtzman

Publication number: 20020167496Abstract: A marking device for digital transcription systems provides a transmitter marking device that is comprised of a modular holder and sleeve. The sleeve is a “smart” sleeve that identifies the color of an inserted drawing implement to the holder. The holder is detachable from the sleeve and houses a battery, electronic circuit, and pressure sensitive switches. The electronic circuit controls the electrical functions of the transmitter marking device and contains electronic circuitry that controls the transmitter device's power and varies the IR transmitter signal by varying the number and duration of the IR pulses as the battery voltage level changes.Type: ApplicationFiled: June 24, 2002Publication date: November 14, 2002Inventors: Yao Ding, Rafi Holtzman

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: 6184873Abstract: A pen positioning system is provided, in which a pen, having multiple output elements, is adapted to accurately determine the location of the pointing tip of the pen, in relation to an electronic tablet. The output elements, preferably ultrasonic transmitters having distinct frequencies, are located a fixed distance from each other, and are also related in space to the pointing tip of the pen. The geometric relationship between the output elements and the pointing tip of the pen allows the location of the pointing tip to be determined, independent of the angle which the pen is inclined against the surface of the writing tablet. A detection system is used to receive the output signals from the output elements, isolate the output signals from each other, and process them independently to determine the location of the output elements and of the pointing tip of the pen.Type: GrantFiled: January 20, 1998Date of Patent: February 6, 2001Assignee: Electronics for Imaging, Inc.Inventors: Daniel R.
