摘要： A method for emendation of attention trajectory in video content analysis is disclosed. The method includes steps of extracting attention area for each frame in a video sequence, each attention area of a frame selectively being a reference for the other frames, projecting the attention area of the reference to a current frame, and determining an enhanced attention area of the current frame by collecting and merging all the projected attention areas together with the original attention area of the current frame to emend the attention trajectory of the video sequence so as to make the attention trajectory smooth. Advantageously, short-life attention or noise is omitted, and the attention area is also enriched, therefore, the smooth of the attention trajectory improves subjective viewing experience of human being.

摘要： A method (400) and apparatus (1000) for compressing digital ink such as a hand-drawn object (104) are provided. The hand-drawn object is first prepared (406, 1010) and then Bezier curves based upon the hand-drawn object are generated (408, 1012). The Bezier curve representation (202) of the hand-drawn object (104) is further compressed (418, 1018) by modifying Bezier control points to produce a compressed Bezier curve representation (302) of the hand-drawn object (104).

摘要： A two component, high temperature, thermally stable explosive composition comprises a liquid or low melting oxidizer and a liquid or low melting organic fuel. The oxidizer and fuel in admixture are incapable of substantial spontaneous exothermic reaction at temperatures on the order of 475.degree. K. At temperatures on the order of 475.degree. K., the oxidizer and fuel in admixture have an activation energy of at least about 40 kcal/mol. As a result of the high activation energy, the preferred explosive compositions are nondetonable as solids at ambient temperature, and become detonable only when heated beyond the melting point. Preferable oxidizers are selected from alkali or alkaline earth metal nitrates, nitrites, perchlorates, and/or mixtures thereof. Preferred fuels are organic compounds having polar hydrophilic groups. The most preferred fuels are guanidinium nitrate, acetamide and mixtures of the two. Most preferred oxidizers are eutectic mixtures of lithium nitrate, potassium nitrate and sodium nitrate, of sodium nitrite, sodium nitrate and potassium nitrate, and of potassium nitrate, calcium nitrate and sodium nitrate.

摘要： A process transfers data packets through a protocol stack employed by a device that transmits packets on a packet connection to a wireless network between at least two, distinct wireless access technologies such as GSM/GPRS and UMTS. A first layer of the stack stores a copy of a transferred packet until confirmation is received from a next, lower layer of successful transfer of the packet of the stack. In the absence of such confirmation and on the occurrence of a switch of the packet connection to a new connection path, particularly one of a different wireless access technology, the stored packet is transferred to the protocol stack to be employed by the wireless device for the new packet connection path. Consequently, the packet transfer process avoids packets being lost on the occurrence of a switch between different technology wireless access packet connection paths.

摘要： The invention is directed to a process for transferring data packets through a protocol stack employed by the device for transmitting packets on a packet connection to a wireless network, said wireless network operating at least two, distinct wireless access technologies such as GSM/GPRS and UMTS. The packet transfer process generally comprises each layer of a protocol stack for a currently active packet connection path providing confirmation to a next, higher layer in the stack of successful reception of a data packet from that layer, thereby confirming successful transfer of the data packet through the stack. The first layer of the stack stores a copy of a transferred packet until such time as its receives confirmation from the next, lower layer of successful transfer of the packet of the stack. In the absence of such confirmation and on the occurrence of a switch (hand-off) of the packet connection to a new connection path, particularly one of a different wireless access technology, the stored packet is transferred to the protocol stack to be employed by the wireless device for the new packet connection path. Consequently, the packet transfer process avoids packets being lost on the occurrence of a switch between different technology wireless access packet connection paths.
