Title: Adaptive modeling and segmentation of visual image streams
Inventor: MOORBY PHILIP R
IPC: G06T7/00
Filed: 1998-04-01
Abstract: A technique for converging upon a computer-based model of a real world or synthetic scene. The computer model makes use of abstraction-based data objects as well as image-based data objects. A correlation mesh provides links between related image-based and abstraction-based objects. An initial step in a process analyzes an input image stream and user inputs to derive initial image-based objects and abstraction-based objects for the scene model.  Subsequent steps in the process allow user inputs to refine the image-based objects, abstraction-based objects and/or the correlation mesh. As a result, refinements to the image-based object model of the scene can improve the abstraction-based model of the scene, and refinements to the abstraction-based object model can improve the image-based model.

Title: Transmitting facility and receiving facility for a multipoint-to-point synchronous cdma network
Inventor: ENSSLE JURGEN
IPC: H04L7/06
Filed: 2000-06-08
Abstract: The object of the invention is to provide an acquisition method for a multipoint-to-point CDMA network (NET) that minimizes the influence of the acquisition procedure on the information transmission. The acquisition signals are encoded in a specific acquisition code that differs from the CDMA communication code of the information signals.      In addition, the acquisition signals are transmitted with an amplitude smaller than that of the information signals. At the receiving end, the acquisition signals are detected by correlation (11) and subsequent accumulation (12). This method maximizes the transmission capacity of the information signals. In addition, the acquisition time is reduced since adaptive contention-resolving techniques can be employed taking account of the estimated number of colliding terminals (2, 3, 4, 5).

Abstract: A connector having at least three parts is used to connect a fluid line to an opening of a component that is made of a thermoplastic material. The connector is produced by forming a first part of the connector from an essentially thermoplastic material. A  second part and a third part of the connector are produced from an essentially thermoplastic material so that the second part and the third part are fused together. The first part and the second part are connected in a fluid-tight manner outside of a mold. The material of the third part is selected so that it is capable of forming a fusion connection with the thermoplastic material of the component. The connector can also have at least one part. This connector is produced by injection molding a first outer part, an inner layer and an intermediate layer. The materials of the first outer part and the inner layer and the material of the intermediate layer are selected so that they have different properties with respect to their strength, impact resistance, and tendency to creep. At least one of the first outer part, the inner layer and the intermediate layer is formed so as to be impervious to diffusion.

Inventor: SUSSMEIER JOHN W
IPC: B43M3/04
Filed: 2000-08-30
Abstract: A method and device for synchronizing the motion between a chassis (master) motor and one or more enclosure feeder (slave) motors in an envelope inserting machine. The motion profile of one motor can be varied with time independently of the others. The displacement mapping method uses encoders, such as optical encoders, to obtain the displacement of each of the associated motors as a function of time. From the actual displacement of the master motor, an electronic computation device or process is used to calculate the theoretical displacement of each slave motor according the motion profile of the slave motor. The theoretical displacement is then compared to the actual displacement. If there is a discrepancy between the theoretical and the actual amount, then the motion of the slave motor will be adjusted so as to eliminate that displacement discrepancy.
