Patent number: 6990435Abstract: A system for detecting tactile information includes strain-gauge touch sensors and a controller. Based on the sum output from each of tough-sensor sensor units, an analyzer in the controller calculates touch force Fi(t) at each measurement point. An automatic gain control adjusts the voltage amplitude Ai(t) of a sine wave of frequency fi applied to the sensor units at each measurement point to bring the voltage amplitude measured at each measurement point in line with a target voltage. The adjusted voltage Ai(t) is applied to the bandpass filter with a composite sine wave y(t) which includes sine waves of each frequency corresponding to the adjusted voltage amplitude Ai(t). This makes it possible to reduce the number of lines between the controller and touch sensors that includes numerous measurement points, and enables the gain of the touch sensors constituted by strain gauges to be controlled within an appropriate range.Type: GrantFiled: October 1, 2003Date of Patent: January 24, 2006Assignee: Harmonic Drive Systems Inc.Inventors: Makoto Kaneko, Ryuta Horie

Patent number: 6693516Abstract: A tactile transducer is able to provide a tactile display or serve as a tactile input sensor. Paired contactors having contactor tips separated by a gap are connected to transducer means (an actuator or sensor). Variations in the gap distance can create a tactile experience through skin stretch, or provide tactile input in sensor mode.Type: GrantFiled: May 10, 2000Date of Patent: February 17, 2004Inventor: Vincent Hayward

Patent number: 6692255Abstract: A refreshable Braille reader apparatus and method are disclosed, the apparatus preferably utilizing a rotating cylinder having endless rows of openings defined therethrough to a display surface with a pin held in each opening and freely movable therein. Static actuators at least equal in number to the rows of openings through the cylinder are maintained at a station adjacent to the surface of the cylinder, and are configured and positioned so that the pins are selectively contactable at either of their ends by different ones of the actuators during cylinder rotation in either forward or reverse direction thereby selectively positioning first ends of the pins relative to the surface of the cylinder to allow streaming of Braille text across a display area in either forward or backward order depending upon selected direction of cylinder rotation.Type: GrantFiled: August 6, 2001Date of Patent: February 17, 2004Assignee: The United States of AmericaInventors: John W. Roberts, Oliver T. Slattery, David W. Kardos, Edwin Mulkens, Bretton Swope

Patent number: 6650338Abstract: The methods and systems of the present invention receive video or image data, for example via television broadcast, cable, or satellite television signal, or directly from a video player, and process the data to determine the geometry and material properties of various objects represented in the video image. Geometry and material property information may be deciphered from a video image by reference to various fixed data sources and/or the application of known methods for elucidating such information from video or image data, such as shape-from-motion or shape-from-shading techniques. Alternatively, all or some of this information may be provided to the system together with the video or image data via a preconfigured side channel. The system coordinates and assembles the image data with the data relating to geometry and material properties of the objects and provides a realistic haptic interaction with those objects to the user.Type: GrantFiled: November 24, 1998Date of Patent: November 18, 2003Assignee: Interval Research CorporationInventors: Krasimir D. Kolarov, Steven E. Saunders

Patent number: 6639510Abstract: A tactile reading system and a communication device for tactile data reading and input with a computer. It includes a set of sensitive means (13, 13′) located each in the proximity of or inside the input means (12, 12′) and arranged such that they can, under the control of the computer, communicate a binary sensation on each one of the user's finger. To each combination of simultaneous detection of sensations on the fingers, corresponds a read character, the character being the same as the one transmitted by the computer under the simultaneous action on the input keys associated with the active reading keys for the combination concerned. The invention is particularly designed for blind people.Type: GrantFiled: October 9, 2001Date of Patent: October 28, 2003Inventor: Philippe Soulie

Publication number: 20030073058Abstract: Single dot tactile reading module including a tactile dot, driven by a rotation of a cam around its axis, either directly or through a pair of levers. A shape memory alloy wire is attached on one hand to a rod which ends can slide in slots cut in internal faces of the cam, on the other hand to a rod held in a fixed position at the bottom of the tactile module. The wire contraction, produce by Joule heating, rotates the cam which in turn moves the dot up or down depending on the direction of the rotation. The wire cooling, accelerated by a heat sink allows the return of the wire to its initial length with help of a spring which pushes the rod from one end to the opposite end of the slots the cam being prevented from rotating by a locking spring having two stable positions, one corresponding to the up position of the dot, the other to its down position.Type: ApplicationFiled: October 11, 2002Publication date: April 17, 2003Inventors: Oleg Tretiakoff, Andree Tretiakoff

Patent number: 6537071Abstract: An apparatus is disclosed for automating the insertion of spherically and non-spherically shaped members on an architectural sign face into pre-drilled holes in the sign corresponding to the pattern of Braille letters designed to be formed in the sign. A device is disclosed for holding a reservoir of spherically or non-spherically shaped members, delivering the members from the reservoir pan to a spindle and hammer assembly whereby the member is forcibly inserted into the pre-drilled hole on the sign face by the spindle and hammer in an arrangement desired for accurately duplicating Braille letters.Type: GrantFiled: July 27, 2001Date of Patent: March 25, 2003Assignee: Accent Signage Systems, Inc.Inventors: Reuven Rahamim, David F. Birch

Patent number: 6481134Abstract: A tag for attaching to a garment having an attribute and identifying the attribute to a person unable to visually identify the attribute. The tag includes a strip for attaching to the garment, and tactically discernable indicia disposed on the strip and being representative of the attribute of the garment. The strip is divided into a plurality of portions that are break-apartable from each other. The tactically discernable indicia includes a plurality of differently formatted discernable indicia that each represent the same attribute of the garment and include a symbol, Braille, and a letter. Each differently formatted discernable indicia is disposed on a different one of the plurality of portions of the strip. Depending upon which of the plurality of differently formatted discernable indicia the person prefers, an associated one of the plurality of portions of the strip is broken off and attached to the garment.Type: GrantFiled: April 2, 2001Date of Patent: November 19, 2002Inventor: Alicia Aledo
