An implantable vessel filter device having a plurality of radially expandable legs with hooks, and a center-post configured to prevent entanglement of the radially expandable legs when they are compressed against the center-post. In one variation, the filter device comprises a first set of legs, forming a first filter basket in the expanded position, and a second set of legs, forming a second filter basket distal to the first filter in the expanded position. Hooks may be provided on the second set of legs to prevent migration of the filter along the vessel after the filter is deployed. Grooves may be provided along the shaft of the center-post to receive the hooks and prevent the hooks from interlocking when the legs of the filter are compressed along the center-post.

A modification to allow delivery of a two port medical flow restrictor over a guidewire, and a means to mechanically collapse the new device. A thin walled, foil-like shell, is compacted for delivery. The invention includes the device, delivery assemblies, and methods of placing, and using, the device. A device with an aneurysm lobe and an artery lobe self-aligns its waist at the neck of an aneurysm as the device shell is pressure expanded. Mechanical force collapses both the aneurysm lobe and the artery lobe, captivating the neck of the aneurysm and securing the device. The device works for aneurysms at bifurcations and aneurysms near side-branch arteries. The device, unlike endovascular coiling, excludes the weak neck of the aneurysm from circulation, while leaving the aneurysm relatively empty. Unlike stent-based exclusion, the device does not block perforator arteries. This exclusion device can also limit flow through body lumens or orifices.

Delivery systems, and methods using the same, having an ultrasound viewing window for improved imaging and a needle for ablation treatment of target tissues. In an embodiment, the target tissue is a fibroid within a female's uterus. In an embodiment, the delivery system includes a rigid shaft having a proximal end, a distal end, and an axial passage extending through the rigid shaft. In an embodiment, the axial passage is configured for removably receiving the ultrasound imaging insert having an ultrasound array disposed a distal portion.

The invention discloses a stream computing system abnormity perception-oriented fault tolerance method and system. The system comprises a computing module, a system monitoring module, a dynamic extension module, a fault recovery module and a computing resource pool module, wherein the system monitoring module periodically detects computing states of all working nodes in the system; when the detected state of a working node is in warning, the working node in the warning state is subjected to preventive fault recovery through interaction of the system monitoring module, the dynamic extension module, the fault recovery module and the computing resource pool module; the system monitoring module further monitors the working node in the warning state, and the fault recovery module performs different processing modes according to changes of the state of the working node from the warning state to a fault state, a normal state and an abnormal state. The fault tolerance method is a fault tolerance method for realizing transparency to a user in a stream computing system. The fault tolerance method disclosed by the invention has a complete fault recovery process, and the fault recovery efficiency of the stream computing system is improved.

A system for ocean bottom sensing for performing geological survey. Herein the system comprising a cable further comprising a cable jacket (9), at least one optical fiber (6), and a plurality of detectors enclosed by the cable jacket (9). The latter including at least a first and a second detector (1, 2), the at least first and second detector (1, 2) comprising at least one intrinsic fiber optic sensor (3x, 3y, 3z, 3h, 3g, 3t). The detectors are communicatively connected to the at least one optical fiber (6) for allowing interrogation of the intrinsic fiber optic sensors (3x, 3y, 3z, 3h, 3g, 3t) and the cable jacket (9) has substantially a same cross-sectional diameter (D) and same outer shape at the at least first and second detector (1,2) and in between said first and second detector (1,2).

The invention discloses a double-clutch friction pair system. One side of the steel plate bracket of the friction plate is mounted with friction material, and the other side is a smooth surface; One side of the material faces one side of the dual plate; the steel plate bracket of the former plate is in direct contact with the friction material of the latter plate, and dissipates the heat generated by the friction between them. The friction pair system of the invention can effectively optimize the heat dissipation effect of the clutch and avoid failure of the clutch due to excessive temperature. At the same time, because the heat dissipation burden of the dual plate and the friction plate steel plate bracket is reduced, the design thickness of the friction pair system can also be correspondingly thinned, the axial length of the clutch is shortened, and the layout of the clutch is significantly improved.

A curtain airbag is proposed to improve the deployability of an airbag cushion while simplifying the structure of the curtain airbag by forming a sub-chamber. The curtain airbag includes a main chamber of an airbag cushion secured to an upper end inside a vehicle body to be deployed to a lower end thereof, a first sub-chamber of the airbag cushion deployed above a pillar trim while pushing the vehicle body to move the main chamber towards a center of a vehicle, and a second sub-chamber of the airbag cushion deployed between an end of the pillar trim and the main chamber, thus pushing the main chamber to prevent the main chamber from being caught by the end of the pillar trim.
