An endoluminal prosthesis including a radially expandable frame and an anchoring member. The anchoring member includes a first arm attached to a first strut of the frame and a second arm attached to a second adjacent strut of the frame. The first arm is joined to the second arm to form a vessel engaging end that, together with at least a portion of the first arm and second arm, is directed toward a central axis of the frame in the frame's collapsed configuration.

The invention presents a method of generating a multicast stream for transporting video content such as live TV. First, the video content is encoded, and segmented into temporal chunks. Each chunk is then encapsulated in one or more RTP packets, depending on the size of the chunk, and each RTP packet is marked with a chunk marker to indicate which of the packets the boundaries between chunks lie. The multicast stream is then generated by encapsulating the RTP packets, preferably using UDP in IP packets. The chunk marker is provided for by a special field in the RTP payload header. The chunk marker can be a chunk index or a chunk offset. Both, individually and in combination, can be used to determine the boundary between chunks.

The invention relates to the technical field of large unmanned aerial vehicles, in particular to a large unmanned aerial vehicle cargo compartment for transportation, which comprises an unmanned aerial vehicle body, a cargo compartment is fixed at the bottom end of the unmanned aerial vehicle body, a lifting structure for lifting articles is arranged on the cargo compartment, and a positioning structure for adjusting the landing positions of the articles is arranged on the cargo compartment. A counterweight structure is arranged on the positioning structure; a supporting structure is arranged on the cargo cabin, and a moving structure is arranged on the cargo cabin; the arrangement of the supporting structure facilitates the adjustment of the supporting height, facilitates the adjustment of the overall maximum occupied space of the unmanned aerial vehicle body, facilitates the adjustment of the position of the moving structure, enables the movement of the unmanned aerial vehicle body to be more convenient and faster, and the arrangement of the lifting structure facilitates the rapid hanging of objects, enables the operation to be more convenient. Meanwhile, when the unmanned aerial vehicle body is used for high-altitude delivery of articles, the delivery position of the articles can be controlled through cooperation of the positioning structure and the counterweight structure, and then delivery is more stable and efficient.

The invention relates to a three-plate type high-energy-consumption viscous damping wall which is arranged between upper and lower floor surface beams and is used for vibration absorption and energy dissipation of a building structure. The three-plate type high-energy-consumption viscous damping wall comprises a wall body and a top sealing piece; the upper floor surface beam, the top sealing piece, the wall body and the lower floor surface beam are connected in sequence; a wall body sealing space is formed by connecting the wall body with the top sealing piece; an energy consumption damping structure is arranged in the wall body sealing space and the wall body sealing space is filled with viscous damping liquid; when a building floor has relative displacement, the energy consumption damping structure can slide in a viscous damping material of the wall body along the vertical direction of the wall body to generate a damping force, so that the energy of earthquakes or a wind load input structure is dissipated and a power reaction of the structure is reduced. Compared with the prior art, the three-plate type high-energy-consumption viscous damping wall has the advantages of strong energy consumption capability, stable performance, deformation resistance, stable output force, damage resistance and the like.

The invention provides a multifunctional walking carrying platform. The multifunctional walking carrying platform is characterized in that the walking carrying platform with the adjustable foot end trajectory comprises a vehicle frame A, a first leg mechanism B-a, a second leg mechanism B-b, a third leg mechanism B-c, and a fourth leg mechanism B-d; and the vehicle frame A is fixedly connected with a first rack B-a-1 of the first leg mechanism B-a, a second rack B-b-1 of the second leg mechanism B-b, a third rack B-c-1 of the third leg mechanism B-c and a fourth rack B-d-1 of the fourth leg mechanism B-d of a traveling assembly. According to the walking carrying platform with the foot end trajectory adjusting function, when the ground working environment changes, the leg mechanisms can change along with the change of the ground working environment, thus foot ends have the different foot end trajectories, and thus the function of stable advancing under different working environments isachieved.
