Publication number: 20060087510Abstract: A method and system of configuring a three-dimensional model using a keyboard. A three-dimensional model is provided that is configurable about a plurality of degrees of freedom in which each respective degree of freedom is associated with a value representing a magnitude of movement from a neutral position. At least one key on a keyboard is associated with each respective degree of freedom of the three-dimensional model. In response to the selection of at least one key on the keyboard, identifying the respective degree of freedom associated with the keyboard selection and adjusting the value associated with the identified degree of freedom. Although keyboard based, this interface allows the user to obtain a desired configuration of the three-dimensional model without prior knowledge of any 3D software and without selecting and applying transformations using a graphical user interface.Type: ApplicationFiled: August 31, 2005Publication date: April 27, 2006Inventors: Nicoletta Adamo-Villani, Gerardo Beni

Patent number: 4871252Abstract: Method and apparatus for positioning a three-dimensional object at a preselected position within a workstation. An optical system in the apparatus creates a 3-dimensional image of the object at the selected preselected position. An imaging device in the apparatus detects macroscopic features related to the extent of volume overlap between the object and image, and this information is used to direct the object, through a mechanical drive, toward a position of greater volume overlap with the image. In one aspect of the invention, the optical system produces a holographic image, and the imaging device is designed to detect both macroscopic features related to volume overlap, and interference fringes which form when the volume overlap between the image and object is within about 50 microns, providing object positioning to within about 50 microns.Type: GrantFiled: October 30, 1986Date of Patent: October 3, 1989Assignee: The Regents of the University of CaliforniaInventors: Gerardo Beni, Alan Mar, C.

Patent number: 4847786Abstract: Method and apparatus for analyzing a 2-dimensional sensory-input field containing three or more distinct classes of objects. The field is represented by a 2-dimensional array of elements in which each separate class of objects in the field has a separate classification value. The field is scanned with a 2.times.2 window containing the element being scanned and three adjacent and connected window elements, where each of the adjacent window elements has been previously assigned an object label which identifies one object containing that element. If the element being scanned has the same classification value as any of the adjacent window element, it is assigned the object label of that same-classification window element. Otherwise, the element being scanned is assigned a new label. If the element being scanned has the same classification value as two adjacent and orthogonal elements, and these orthogonal elements have been previously given different object labels, the two different object labels are merged.Type: GrantFiled: August 20, 1986Date of Patent: July 11, 1989Assignee: The Regents of the University of CaliforniaInventors: Jing Wang, Gerardo Beni

Patent number: 4588348Abstract: A movable part of a robot, such as the fingers of the robot hand, are provided with an array of tactile elements mounted on a substrate. Each element includes a magnetic dipole embedded in a compliant medium on one side of the substrate and a magnetic sensor on the other side of the substrate. The dipole and sensor are in parallel planes. A force or torque deforms the compliant medium and displaces the magnetic dipoles with respect to the sensor. The sensor detects the change in magnetic field and produces an electrical signal which is used to control the robot. Magnetoresistive sensors are preferred. To detect torque, each element illustratively includes four sensors arranged at 90.degree. to one another and a magnetic dipole oriented at 45.degree. to each sensor.Type: GrantFiled: May 27, 1983Date of Patent: May 13, 1986Assignee: AT&T Bell LaboratoriesInventors: Gerardo Beni, Susan Hackwood, Lawrence A. Hornak

Patent number: 4545713Abstract: An articulating waveguide arm assembly, comprising long arm segments, (11, 12, 15, 17, 19) and short corner segments (13, 14, 16, 18) has a single-mode hollow dielectric waveguide located inside each segment and an optically reflecting device (33, 34, 37, 38, 39) located at the end of each segment. The waveguide assembly is mechanically affixed to a robot assembly having protruding side shields (65, 66). The robot assembly includes a pair of long arms (61, 62) corresponding to a pair of the waveguide arms (15, 17). Another waveguide arm segment (12) of the waveguide assembly passes over the protruding side shields and terminates in a pair of successive corner segments (13, 14) for enabling a laser beam propagating through this long arm segment to enter into one of the pair of long waveguide segments (61).Type: GrantFiled: November 10, 1983Date of Patent: October 8, 1985Assignee: AT&T Bell LaboratoriesInventors: Gerardo Beni, Thomas J. Bridges, Susan Hackwood, Chinlon Lin

Patent number: 4417786Abstract: An optical change in a device is produced through modification of the surface tension between two materials by the change of an electric field. For example, such a device is formed by introducing an electrolyte and a metal such as mercury into a capillary tube. The surface tension between the two fluids is changed through application of a voltage between them. When the surface tension is altered the relative positions of the fluids in the tube also change. Thus, it is possible to introduce one fluid into a portion of the tube which contained the other before the change in voltage, i.e., the position of the interface between the fluids, is moved. If the two fluids have different colors, the translation produces a color change if the area of the tube near the initial interface position is viewed.Type: GrantFiled: June 11, 1981Date of Patent: November 29, 1983Assignee: Bell Telephone Laboratories, IncorporatedInventors: Gerardo Beni, Susan Hackwood

Patent number: 4411495Abstract: A display cell having at least two states of different opacity, comprises a first material having a first index of refraction, a second material dispersed within the first material and having a second index of refraction, the difference between the first and the second indices of refraction being variable over a range of values, and means for varying the difference in index of refraction over a portion of the range. When the indices of refraction of the first and second material are substantially the same, the display is substantially transparent. Otherwise it is opaque or substantially less transparent.Type: GrantFiled: April 15, 1981Date of Patent: October 25, 1983Assignee: Bell Telephone Laboratories, IncorporatedInventors: Gerardo Beni, Harold G.

Patent number: 4201454Abstract: Electrochromic devices based on anodic iridium oxide as the electrochromic material have been made. These devices exhibit long term stability, memory, and good response times, e.g., less than 80 msec. for reflectivity changes of about 70% (50 msec. for 50% changes). Devices using an anodic iridium oxide film immersed in a sulfate electrolyte have been operated for more than 6.times.10.sup.5 coloration/bleaching cycles at 0.5 Hz without noticeable change in properties. Response times and stability are also improved by a heat treatment of the anodic iridium oxide at temperatures between 40 and 100 degrees C.Type: GrantFiled: June 27, 1978Date of Patent: May 6, 1980Assignee: Bell Telephone Laboratories, IncorporatedInventors: Gerardo Beni, Joseph L.
