A technique for eliminating duplicate data is provided. Upon receipt of a new data set, one or more anchor points are identified within the data set. A bit-by-bit data comparison is then performed of the region surrounding the anchor point in the received data set with the region surrounding an anchor point stored within a pattern database to identify forward / backward delta values. The duplicate data identified by the anchor point, forward and backward delta values is then replaced in the received data set with a storage indicator.

A joining pin (3.2) with which two parts (1 and 2) made from a porous material, particularly wood or a wood-like material, are to be joined together, is anchored in the porous material at predetermined anchoring points (31, 33). For this purpose, a bore (4.2) with a closed inner end (41) is made in the parts (1 and 2). The shape of this bore (4.2) is so matched to the joining pin (3.2) that it can be introduced substantially without force expenditure into the bore and is positionable in a first position. At least one predetermined anchoring point (31, 33) between the joining pin (3.2) and the wall of the bore (4.2) is formed when pressure is built up by pressing the joining pin (3.2) with a pressing force (F) more deeply into the bore to a second position. Energy is supplied in a planned manner to the joining pin (3.2) so that at the predetermined anchoring points (31, 33) the thermoplastic material of the joining pin (3.2) is plasticized. The locally plasticized plastic material is pressed by the local pressure into the porous material of the parts and forms local, macroscopic anchors (10, 20). The joining pin (3.2) is, e.g., made entirely from a thermoplastic material and the energy for plasticizing is supplied thereto by ultrasonic vibration.

For machine segmenting of speech, first utterances from a database of known spoken words are classified and segmented into three broad phonetic classes (BPC) voiced, unvoiced, and silence. Next, using preliminary segmentation positions as anchor points, sequence-constrained vector quantization is used for further segmentation into phoneme-like units. Finally, exact tuning to the segmented phonemes is done through Hidden-Markov Modelling and after training a diphone set is composed for further usage.

The invention solves the problem of reducing interference in simultaneous wireless LAN (WLAN) and Bluetooth signal handling, especially in voice over IP communications via a WLAN telephone to a Bluetooth headset. The invention sets up a voice link between the terminal and the headset by establishing sniff anchor points in the ACL link for assigning relative priorities to the WLAN and Bluetooth ACL packet traffic. A higher priority is assigned to WLAN packet traffic when it collides with original Bluetooth ACL packet traffic during a sniff anchor point. Thereafter, a higher priority is assigned to the terminal's retransmission of aborted Bluetooth ACL packets and the headset's response ACL packets in available Bluetooth slots following the anchor point.

A compound bow or crossbow employs bowstring cams with bowstring cam grooves and power cord cam grooves. Preferably a pair of generally identical power cord cam grooves are positioned axially above and below the bowstring cam groove. The power cords are anchored to a fixed anchor point, e.g., a pylon, on the near end of the riser or on the near side of the crossbow bar or stock. The power cords do not cross over to the other limb. The reduction in the number of cam wheels and pulleys and in the number of strings or cords results in greater efficiency and higher transfer of energy from the bow to the arrow or bolt. There is no drop-off in pull weight at full draw. The bolt or arrow accelerates throughout the travel of the bowstring, resulting in significantly higher velocity.

A medical assembly is used to deliver a therapeutic substance to a treatment area. The medical assembly comprises a catheter having a distal end and a proximal end, a transducer supported by at least a portion of the distal end of the catheter assembly, and a delivery lumen mounted on the catheter for delivery of a therapeutic substance. Support for the transducer is provided at a preselected number of anchoring points, wherein an inner surface of the transducer is positioned at a preselected distance from an outer surface of the catheter. The preselected distance defines a gap that is occupied by a low density material such as a gas which reflects acoustic pressure waves directed toward the gap by a transducer when a voltage is applied to the transducer. The reflected pressure wave increases the energy in the system, enhancing transport of therapeutic substances from the delivery lumen to the surrounding tissues and / or cells to be treated. The medical assembly may optionally be used in conjunction with both macroporous and microporous balloons. The medical assembly may optionally be modified so that a plurality of transducers are used, wherein the distal end of a transducer is positioned at a preselected distance from the proximal end of an adjacent transducer.

A method for digital video distribution includes transmitting a multicast stream over a network. Upon receiving, at a time subsequent to a first anchor point and prior to a second anchor point in the multicast stream, a request from a client to begin receiving the multicast stream, a boost stream is generated, including at least a portion of the video data in the frames between the first and second anchor points. The boost stream is transmitted to the client during an interval between the time at which the request was received and the second anchor point in the multicast stream, so as to cause the client to display the video data beginning from the first anchor point. Upon completing transmission of the boost stream, the multicast stream is transmitted to the client beginning from the second anchor point.

The present invention provides a method for hierarchically decomposing a visual or audio object within an animation into plurality of objects which can be individually edited to achieve particular animation effects. For example, a graphical object may be decomposed into a plurality of graphical sub-objects, each of which is inherits an anchor point from the original object, or is given an original anchor point distinct from the original object. Each sub-object also includes a relative position for the sub-object relative to the anchor point. The path of the anchor point is combined with relative positions of the sub-objects to produce an animation for the object as a whole. This decomposition technique can greatly increase computational efficiency of an animation. It also provides for inheritance of attributes between objects and descendent sub-objects. The objects may support functions, or behaviors, such as morphing or motion blurring. The present invention additionally provides a flexible grouping operation to facilitate modifications to a group of objects. When a first type of modification is made to an attribute of an object in a group, this change is applied to corresponding attributes of other objects in the group. When a second type of modification is made to an attribute of an object in a group, the change only applies to the selected object or objects, and not to other objects in the group. The present invention allows objects to be manipulated on servers which are connected to a display via the Internet.
