Patent number: 6570924Abstract: An entropy efficient video coder for wavelet pyramids approaches the entropy-limited coding rate of video wavelet pyramids, is fast in both hardware and software implementations, and has low complexity (no multiplies) for use in ASICs. It uses a modified Z-coder to code the zero/non-zero significance function and Huffman coding for the non-zero coefficients themselves. The encoding unit includes a significance function generator that receives coefficients and outputs a single significance bit. A zero coefficient eliminator receives coefficients in parallel with the significance function generator and outputs coefficients if non-zero. Output from the significance function generator is coded using the modified Z-coder. Output from the zero coefficient eliminator is coded using Huffman coding. Both outputs are combined to form the resulting compressed stream.Type: GrantFiled: November 19, 1999Date of Patent: May 27, 2003Assignee: Interval Research CorpInventors: William C.

Patent number: 6556184Abstract: A computerized interactor system uses physical, three-dimensional objects as metaphors for input of user intent to a computer system. When one or more interactors are engaged with a detection field, the detection field reads an identifier associated with the object and communicates the identifier to a computer system. The computer system determines the meaning of the interactor based upon its identifier and upon a semantic context in which the computer system is operating. One specific embodiment of the present invention is a bead interactor system that is a user playable sound and light show system. When an interactor bead is positioned within the detection space of the bead interactor system, a sound sequence begins and continues to play unaltered until the bead interactor is removed or other bead interactors are positioned within or removed from the detection space.Type: GrantFiled: November 16, 2001Date of Patent: April 29, 2003Assignee: Interval Research CorpInventors: Emily Weil, Greg Thomas, S.

Patent number: 6525711Abstract: A user can selectively engage some part or all of the haptic display of a haptic interface device to produce an enhanced interaction with an environment with which the user interacts using the haptic interface device. Further, the haptic interface device can be implemented so that the part of the haptic display that is engaged can be engaged to varying degree. The degree of engagement with the haptic display (together with whether part or all of the haptic display is engaged) determines the manner in which the haptic display is experienced by the user. The selective engagement with the haptic display is enabled by adding a haptic clutch model to the underlying haptic model used to produce the haptic display, the haptic clutch model engaging some part or all of the haptic model in response to user input. The addition of a haptic clutch model to the haptic model used to produce a haptic display provides a richer user interaction than is provided by a haptic display produced by the haptic model alone.Type: GrantFiled: June 24, 1999Date of Patent: February 25, 2003Assignee: Interval Research Corp.Inventors: Robert S. Shaw, Scott S. Snibbe, William L. Verplank, Karon E. MacLean
