Title: Frame synchronization in multicarrier transmission systems
Inventor: ASLANIS JAMES T
IPC: H04L7/08
Filed: 1995-07-11
Granted: 2001-09-18
Abstract: A discrete multitone modulation transmission system is described in which frame synchronization is monitored at the receiver by correlating frequency domain complex amplitudes of a synchronizing frame with a stored synchronizing pattern. If the correlation result falls below a threshold, indicating a loss of frame synchronization, a plurality of correlations are performed, in each case using the stored complex amplitudes of the synchronizing frame multiplied by a respective complex value representing a respective complex derotation corresponding to a respective possible time shift of the synchronizing frame.  The best correlation result, if it exceeds another threshold, indicates a time shift for restoring frame synchronization, this being possible before the next synchronizing frame is received.

Title: A system for establishing a three-dimensional garbage matte which enables simplified adjusting of spatial relationships between physical and virtual scene elements
Inventor: ROHLFING THOMAS R
IPC: H04N5/222
Filed: 1998-05-25
Granted: 2008-09-23
Abstract: A new method and apparatus for creating, positioning and manipulating a garbage matte which obscures everything outside of a three-dimensional physical set or blue stage. Effectively, the garbage matte is a "negative" of a blue stage. What is important is that the garbage matte is created either as a virtual enclosure around all virtual objects in the virtual environment, or simply as a background color of the graphics engine generating the garbage matte. In this way, the garbage matte provides extensions of blue screens which comprise the blue stage, extending all the way around and behind the television cameras. Consequently, a compositor will not include in a composited output image those physical set elements which are masked by the virtual garbage matte. The compositor will replace areas hidden by the garbage matte with image data supplied by the computer image generator which stores the virtual environment. Furthermore, it is now possible to move the virtual location of the physical set (including the television cameras) within the virtual environment without having to readjust the position of the garbage matte relative to the model by anchoring virtual objects together so as to maintain relative position relationships at all times.

Title: A method and apparatus for performing minimally invasive cardiac procedures
Inventor: LABY KEITH PHILLIP
IPC: A61B19/08
Filed: 1997-02-19
Granted: 2006-08-15
Abstract: This invention is a system (10) for performing minimally invasive cardiac procedures. The system includes a pair of surgical instruments that are coupled to a pair of robot arms (16, 18). The instrumen ts (22, 24) have end effectors that can be manipulated to hold and suture tissue. The robotistic arms are coupled to a pair of master handl es (50, 52) by a controller. The handles can be moved by the surgeon to produce a corresponding movement of the end effectors. The moveme nt of the handles is scaled so that the end effectors have a corresponding movement that is different, typically smaller, than the moveme nt performed by the hands of the surgeon. The scale factor is adjustable so that the surgeon can control the resolution of the end effecto r movement. The movement of the end effector can be controlled by an input button, so that the end effector only moves when the button is depressed by the surgeon. The input button allows the surgeon to adjust the position of the handles without moving the end effector, so th at the handles can be moved to a more comfortable position.
