The present invention provides modular intraluminal tubular prostheses, particularly stents and stent-grafts, for the treatment of disease conditions, particularly aneurysms. Modular sections of the prostheses, or "prosthetic modules," may be selectively combined to form a composite prosthesis having characteristics which are tailored to the specific requirements of the patient. Each prosthetic module preferably includes one or more standard interface ends for engaging another module, the module/module interface typically comprising ends which overlap and/or lock within a predetermined axial range. Advantageously, the axial length, cross-section, perimeter, resilient expansive force, axial flexibility, liner permeability, liner extensibility, radial conformability, liner/tubal wall sealing and anchoring, and other prosthetic characteristics may be varied along the axis of the composite prosthesis, and also along the axis of each prosthetic module. The modules are preferably individually introduced into a lumen system of a patient body so that the composite prosthesis is assembled in situ. Ideally, selection of appropriate prosthetic modules and the flexibility of the interface overlap range provides a custom fit intraluminal prosthesis which provides a therapy tailored to the individual patient's needs.

A nose cone assembly for a gas turbine engine comprises a spinner and a plurality of circumferentially spaced mounting members for mounting the spinner on a fan hub of the gas turbine engine. Each of the mounting members is rigid in a generally axial direction and flexible in a generally radial direction.

A surgical access device for use in laparoscopic surgical procedures includes a housing portion and at least one moveable device port. The housing portion has an axial bore extending therethrough, defining a central axis of the surgical access device. The at least one moveable device port is moveable about an annular path corresponding to an annular seal member. Each moveable device port defines a lumen extending therethrough, and each lumen is substantially parallel to the central axis of the surgical access device.

A brake shoe assembly comprising a brake shoe to which brake plates are assembled. The brake shoe and brake plates are connected by a key or tang in one to a key way or slot in the other. Preassembled fasteners are provided on the brake plates to facilitate alignment of the brake plates with the brake shoe so that the key is received in the slot. Fasteners may be provided in four open corner areas so that the brake plate may be secured to the brake shoe with metal-to-metal contact where the brake plate is secured to the brake shoe. A brake shoe having a cylindrical outer surface or an outer surface defined by a plurality of flats is provided.

The invention relates to a launching device for a sub-caliber artillery projectile employing a base with sliding band, the base being linked to sabot sectors by means of hinges that can be detached during flight, the opening of the sabot being activated thanks to the dynamic air pressure on the flared shapes to the fore of the sectors, said hinge is flanged radially so as to prevent its becoming separated from the sabot sectors 5 outside of the flight phase.

The invention discloses a mobile phone lens cleaning production line device, which comprises a feed mechanism, a cleaning mechanism and a drying mechanism, and is characterized in that: the inside of at least one of the feed mechanism, the cleaning mechanism and the drying mechanism is provided with a worm and worm gear transmission device for transmitting lenses of mobile phones. The mobile phone lens cleaning production line device has the characteristics of good cleaning effect, high drying efficiency and stable transmission.

In certain embodiments, an entertainment system includes a housing configured to be mounted to a headrest. The housing can define a first hinge portion, a base wall, and one or more sidewalls. The housing can include a lock portion. In some embodiments, the system includes a screen assembly including a viewing screen. The screen assembly can define a second hinge portion that cooperates with the first hinge portion to pivotally couple the screen assembly with the housing. The screen assembly can further define an arm movable relative to the viewing screen. The arm can be configured to interact with the lock portion to retain the screen assembly in a stowed configuration in which the screen assembly is substantially prevented from moving away from the base wall of the housing. The arm further can be configured to be actuated to permit rotation of the screen assembly away from the base wall of the housing. In some embodiments, the system includes a headrest configured to be installed in a vehicle.

A redundant release apparatus having a multi-segment split spool with a central bore adapted to axially restrain a tensioned member. Two tensioned tapes are overlappingly wound around the spool segments thereby preventing radial movement of the spool segments. Overlapping winding design of each of the tapes provide predictable unwinding dynamics upon release. The multiple segments require less radial motion for release of the tensioned member.

The invention discloses a master-slave intervention operation robot slave side operating device and a control method thereof, and belongs to the technical field of machinery manufacturing. The device comprises a mobile platform, a shell, a body, a telescoping mechanism, two locking switching mechanisms and a guide wire; the shell is installed on a base of the mobile platform, the body is assembled in the shell, one end of the telescoping mechanism is fixedly connected with the shell, the other end of the telescoping mechanism is fixedly connected with an operating table, and the two locking switching mechanisms are arranged on the outer side of the shell and the outer side of the telescoping mechanism respectively. According to the master-slave intervention operation robot slave side operating device, by optimally designing the slave side body, the telescoping mechanism and the locking switching mechanisms, the problems that guide wire pushing is bent, the pushing force is difficult to measure, assembling and disassembling are inconvenient, and guide clamping and loosening switching is uncontrollable are solved, and the advantages of being reasonable in structure, easy to machine and manufacture and convenient to control are achieved.

The invention relates to an exhaust gas turbocharger (1) having a housing and having a shaft (2) which is arranged so as to be capable of rotating about its longitudinal axis in the housing and on which a turbine wheel (4) and a compressor wheel (3) are seated and which is guided in radial bearings (5, 6) and in at least one axial bearing (9), the radial bearings (5, 6) being embodied as passive, permanent-magnetic bearings which each have a bearing plate (12, 16) which is seated on the shaft (2) as a rotor, and at least one stator (19, 20, 21, 22) which is disposed axially opposite to said rotor. In order to achieve a radial oscillation damping of the shaft (2) in a simple manner, it is proposed according to the invention that a resilient element (60, 61) is disposed between the stator (19, 20, 21, 22) and a part (37, 38) which is fixed to the housing.
