Abstract: This disclosure provides a technique for hierarchical packet marking for Core-Stateless Active Queue Management (CSAQM). In particular, a network node measures the bitrate of each of a plurality of subflows that comprise a traffic aggregate (TA). The plurality of subflows in the TA belong to a single entity, and each subflow has a normalized weight value. The node modifies a random rate determination for a throughput-value function (TVF) associated with the TA based on the bitrates and weight of each subflow in the TA. Then, based on the modified rate, the node calculates a packet value (PV) with which to mark a packet in a given subflow, and marks the packet with the PV. Marking packets according to the techniques disclosed herein achieves a desired weighted resource sharing, and ensures that the random rates are uniformly distributed for the entire TA.

Abstract: Methods and apparatus for packet marking for a Hierarchical Quality of Service (HQoS) is provided to control resource sharing among a plurality of network flows with differentiated services. A packet marker at a single point (e.g., gateway) encodes the resource sharing policy for a plurality of packet flows into a single packet value. The HQoS policy is then realized by using simple PPV schedulers at the bottlenecks in the network.

Abstract: A 3D modeling system for automatically generating fully-textured 3D models of objects from a sequence of images taken around the objects is disclosed. There are several processes developed to facilitate the operation of the 3D modeling system by an ordinary skilled person. One of the processes is the automatic calibration of a camera using only a portion of a calibration disc to essentially provide a larger effective field of view of the camera. Another process is a space carving process that subdivides volumetric cells recursively to fit to a 3D object using a tree structure that encodes the entire process. Still another process is a 3D mesh model generation process that begins with the tree structure and generates self-constraint and interconnected triangles, in a sense that all triangles intersect with each other either not at all or at common boundary faces, to represent the shape of the 3D object.

Abstract: The invention concerns a method for accessing information from a network data source, where the network data source is managed by a server means. In the method an information request is sent through the network to the server means from a requesting telecommunication means, and information is retrieved from the data source with the server means. The information retrieved from the data source is forwarded to a receiving telecommunication means, and further the information used at the receiving telecommunication means is transformed. According to the invention, dynamically determined unique transformation data is associated to the information request, where the transformation data is determined based upon a predetermined and/or previously fixed parameter system. The requested information is transformed based on the unique transformation data, and the information transformed according to the unique transformation data is used at the receiving telecommunication means.

Abstract: A 3D modeling system employing a commercially available structured light source is disclosed. The light source projecting a light stripe is swung manually across an object or a particular area of interest on the surface of the object. Under the illumination of the swinging light stripe, the object is imaged to produce a sequence of images. For each of the images, the position and orientation of the structured light source are independently and dynamically derived. From each of the images, a set of curvilinear points from the (deformed) projected line falling on the object or the area of interest are calculated in conjunction with a calibration model of the imager. The curvilinear points from all the images are merged to provide accurate and complete 3D data about the object or the area of interest.
