Filed:

Apr 20, 2001

Appl. No.:

09/674821

Inventors:

David S. Levy - Seal Beach CA
Robert Scarmozzino - Montrose NY

Assignee:

The Trustees of Columbia University of the City of New York - New York NY

International Classification:

G02B 626

US Classification:

385 15, 385 16, 385 17, 385 39

Abstract:

The Multimode Interference coupler according to the invention has smoothly continuous inwardly tapered sidewalls ( ) which define the width of the multimode region (W ) along the propagation axis of the device. The inward taper causes the average width of the device to be reduced in comparison to known couplers having straight sidewalls ( ). Further, invention allows the access waveguides ( ) to remain sufficiently spaced, while reducing the overall length of the device, to avoid lithographic gap fill-in and unwanted optical coupling between the waveguides.

Nuance Communications, Inc. - Burlington MA

International Classification:

G09B 1/00
G06F 3/041

US Classification:

434167, 434169, 434362, 345173

Abstract:

A method of interpreting keypad input includes identifying a first letter of a target word from activation of an initial key, identifying a set of possible intermediate letters of the target word in response to non-activating traversal of associated keys of the keypad following activation of the initial key, identifying a last letter of the target word from activation of a final key following the non-activating traversal, and then determining the target word based upon the identified first, intermediate and last letters. The method is particularly useful in key input devices sensitive to non-activating finger position above the keys.

Abstract:

A device and method for producing individualized meals according to the visual desires of each diner at a restaurant. Reservoirs of viscous foodstuff is deposited by an XY or XYZ plotter to simulate edible images and then cooked prior to diners immediately consuming them. The high-volume system includes a rotary shuttle table that contemporaneously prints, cooks, flips and dispenses food products, especially pancakes. Patrons draw images using drawing implements whose colors coincide with the viscous foodstuffs in the reservoirs. These images are digitally scanned and the data is used to drive the XY plotter thereby enabling colored printed food to correlate with images drawn by patrons immediately prior to ordering.

Abstract:

The system and method for building an engagement advertisement disclosed herein includes enabling an advertiser to choose from multiple design templates and specify phases to create a rich, interactive advertisement. The engagement advertisement can be deployed onto the Internet, where a viewer can take part in an advertising experience based on the engagement advertisement. The advertising experience includes phases, and the viewer may be required to perform at least one action in a phase in order to advance to another phase. A completion to the advertising experience may be signified to the viewer, and in response to the completion to the advertising experience, the viewer may optionally be provided with a remuneration. The engagement advertisement may be used either as a stand-alone engagement advertisement or as part of a campaign, which includes targeting data, start/end dates, and a budget.

International Classification:

G06F 300

US Classification:

395161

Abstract:

A graphics editor generates an Appearance Construction Graph (ACG) which represents an image formation process as a Directed Acyclic Graph (DAG). The ACG image transformation operations (transforms), and outputs (viewable images--sinks) which can be displayed, for example, in a window of a display screen, and manipulated to construct and edit complex images. Accordingly, the displayed ACG is a user interface that permits complex graphics images to be constructed in a straightforward manner, and thus easily understood and manipulated (edited) by an operator. The nodes in the ACG are selectively interconnected by links (edges). The complex image represented by the ACG can be constructed and displayed in a viewer window on the display screen by "running" the ACG. The graphics editor "runs" the ACG by performing operations on the image fragments as defined by the interconnected nodes of the ACG. When the ACG is "run", each output (or viewer) node displays its image in a viewer window which is automatically created.

Abstract:

The system and methods described herein provide a way for writers and publishers to stand behind individual and combined facts in their work by offering a bounty to a person who can supersede their own data in support of the fact's accuracy with better data, as measured by a pre-established fact evaluation guideline. Once sufficiently vetted by this system, facts are added to an apolitical certified fact database. Facts in the certified fact database also have a bounty upon their accuracy, however financial responsibility for the bounty is transferred to the system. Subscribers to the system may then download and use fact contained within the certified fact database to enhance their own work, while benefiting from the enhanced readership, interest and. trustworthiness provided by virtue of the bounty.

Inventors:

David Levy - Berkeley CA, US

International Classification:

A61B 17/16

Abstract:

Disclosed herein are bi-spring surgical hammer impact tools and methods of use thereof. The bi-spring surgical hammer impact tools can include an elongated drive rod disposed in the housing and including an impact flange in a mid-region thereof. A tool implement can be mounted to a first end of the elongated drive rod. An impact shuttle can be mounted on the elongated drive rod and can include first and second impact surfaces opposing opposite faces of the impact flange. A plurality of annular teeth can be defined by an exterior surface of the impact shuttle. First and second springs can be disposed against opposite ends of the impact shuttle. A partial tooth pinion attached to a drive shaft and movable for engagement with the plurality of annular teeth of the impact shuttle can be included.
