Title: Generating action data for the animation of characters
Inventor: GAUTHIER ANDRE
IPC: G06T13/40
Filed: 2000-07-28
Abstract: Action data for the animation of characters is generated in a computer animation system. Body part positions for a selected character are positioned in response to body part positions captured from performance data. The positions and orientations of body parts are identified for a generic actor in response to a performance in combination with a bio-mechanical model. As a separate stage of processing, positions and orientations of body parts for a character are identified in response to the position and orientation of body parts for the generic actor in combination with a bio-mechanical model. Registration data for the performance associates body parts of the performance and body parts of the generic actor. Similar registration data for the character associates body parts in the generic actor with body parts of the character. In this way, using the generic actor model, it is possible to combine any performance data that has been registered to the generic actor with any character definitions that have been associated to a similar generic actor.

Abstract: A method for forming a spherical concave surface includes the steps of bringing a tool into contact with a material to be formed, rotating the material around a predetermined axis, and moving the tool in a first direction parallel to a central axis of the tool and is a second direction perpendicular to the first direction for forming the spherical concave surface on the material about the predetermined axis. In this method, a first angle of the central axis of the tool relative to the predetermined axis is selected to be greater than oe equal to a second angle of a tangent at a first end of the spherical concave surface in a cross- sectional plane including the predetermined axis relative to the predetermined axis. Because the tool may be moved only in one direction with respect to the second direction, a sudden recoil does not occur in a power transmitting mechanism in the processing machine.      Consequently , the shperical concave surface may be formed in a desired target spherical shape without generating any inconvenient variation caused by a sudden recoil.

Abstract: An apparatus and method for treating a cathode material provided on a surface of a continuous thin-film substrate and a treated thin-film cathode having increased smoothness are disclosed. A web of untreated cathode material is moved between a feed mechanism and a take-up mechanism, and passed through a treatment station. The web of cathode material typically includes areas having surface defects, such as prominences extending from the surface of the cathode material. The surface of the cathode material is treated with an abrasive material to reduce the height of the prominences so as to increase an 85 degree gloss value of the cathode material surface by at least approximately 10. The web of cathode material may be subjected to a subsequent abrasive treatment at the same or other treatment station. Burnishing or lapping film is employed at a treatment station to process the cathode material. An abrasive roller may alternatively be used to process the web of cathode material. The apparatus and method of the present invention may also be employed to treat the surface of a lithium anode foil so as to cleanse and reduce the roughness of the anode foil surface.

Title: Monitor for display re-imaging and display re-imaging system
Inventor: KANEKO TAKAHIRO
IPC: G09G3/36
Filed: 2000-09-29
Abstract: The display re-imaging system comprises a monitor (1) for display re-imaging and a television camera (30) having a display of the monitor for display re-imaging in a part of a field of view of the television camera. The monitor (1) consists of an LCD monitor comprising a back light: (11) including cold cathode fluorescent lamps (11-1 to 11-4) as a light source having a prescribed color temperature, and a non-self-light-emitting display panel (13) for selectively transmitting light emitted from the back light according to an image signal.  The color temperature of the cold cathode fluorescent lamps (11-1 to 11-4) is adjusted to a level corresponding to a reddish color to match with the color temperature of the re-imaging environment. According to such a monitor (1) for display re-imaging and a display re-imaging system, because the color temperature correction is performed on the back light itself, there is no problem of reduced brightness as was the case with the conventional RGB and filter adjustment methods that were used in connection with the conventional monitors for display re-imaging and display re-imaging systems using LCD panels. As a result, the monitor has a thin profile, consumes little power, and provides a bright display as compared to the conventional CRT display.

IPC: H04M3/51
Filed: 2001-03-12
Abstract: Selection of communications for service observing in an ACD system (103) is based on real-time dynamic parameters, i.e., on the present values of parameters whose values for the ACD system change over time. A supervisor/observer or an administrator selects (FIG. 2 or FIG. 5) one or more real-time dynamic parameters that correspond to communications whose servicing is sought to be observed. The correspondence may be either direct or indirect (e.g., correspondence to the agent (101 or 102) that services the communication). Call vectoring (111) or station prompting (112) of the ACD system then determines (302,304), from among the communications that are to be serviced at the ACD system, a communication whose corresponding one or more parameters meet the specified parameters, and connects (310) the determined communication to the service-observer's station (105) in addition to connecting the communication to the servicing agent, so that servicing of the communication by the agent may be observed by the observer. When the observed communication ends, the observer may observe the next communication that meets the selected parameters without needing to re-enter them.

Title: High-performance error-correcting codes with skew mapping
Inventor: GUINAND PAUL
IPC: H03M13/27
Filed: 2001-05-25
Abstract: A method for generating new forward error correction codes, called skew codes, for the reliable transmission of data in noisy channels is disclosed. The method involves adding additional sets of parity equations across the third dimension of a cubic array of bits. The parity equations are applied to the cubic array such that the rectangular patterns of one square array do not match up with a rectangular pattern in another square array. By selecting skew mapping parameters of the parity equations from a set of quadratic residues of prime numbers according to specific design rules, the resulting codes are well suited to low-complexity high-speed iterative decoding, and have error correction performance and error detection capability, particularly for applications requiring high code rates. An improved decoding method for decoding skew codes and any code that is defined by a set of sum-to-identity parity equations initially decoded using an algorithm that provides confidence values on all the symbols at every symbol time is also disclosed. Generally, the improved decoding method will make hard decisions based upon the soft decisions passed from the failed iterative decoding system to provide a valid code word, through manipulation of the parity check matrix and reduction of its columns and rows.

Title: Directional resistivity measurements for azimuthal proximity detection of bed boundaries
Inventor: HAGIWARA TERUHIKO
IPC: G01V3/30
Filed: 2000-02-10
Abstract: An azimuthally tunable resistivity measurement tool (202) comprises a set of three skewed receiver antennas (216, 218, 220) and a transmitter antenna (104, 108). The three skewed receiver antennas are oriented in equally spaced azimuthal directions. The transmitter antenna transmits a radio-frequency signal that propagates through the formation surrounding a borehole. Signals from the three receiver antennas can be measured and combined to synthesize the signal that would be received by a virtual antenna oriented in any desired direction. Virtual receivers oriented perpendicular to the tool axis and with variable azimuthal orientation can be synthesized. Orientation of such a virtual receiver that has a maximized receive signal amplitude can be used to identify the direction of a nearby bed boundary, and the maximized amplitude can be used to estimate the distance to the boundary.  In another embodiment, the tool comprises a set of three skewed transmitter antennas (208, 210, 212) and a receiver antenna (112). In yet anotherembodiment, the tool comprises a set of skewed transmitter antennas (208, 210, 212) and a set of skewed receiver antennas (216, 218, 220).
