A cage and sleeve assembly for an embolic filtering device used to filter embolic particles from a body vessel has a strut assembly that is movable between an unexpanded position and an expanded position. The struts are configured to form a cage having an open cell design. The open cell design provides a filter cage with increased radial flexibility that also increases the contact with a vessel wall while reducing the landing zone length. Such an open cell design may have one or more rings that are not connected together at each vertex, and may be constructed from one ring. The sleeve assembly of the embolic filtering device may be joined to the filter cage at each vertex of the open cell or along the periphery of the open cell.

A method and device for reducing paravalvular leakage upon implantation of a replacement heart valve is provided. The valve assembly includes a tissue or bioprosthetic heart valve attached to an anchoring structure. The anchoring structure includes an inlet rim that is substantially C-shaped in cross section to form a concave landing zone. The anchoring structure self-seats when implanted in the sinus of a patient with the proximal and distal ends of the C-shaped inlet rim pushed against the aorta to effectively prevent paravalvular leakage.

The first discrete fastener element group includes at least one first discrete fastener element having a profile height. The base material has a profile height that is greater than the profile height of the first discrete fastener element. The landing zone may be associated with the outer cover in the front waist region between the front ear regions.

The invention relates to an absorbent product, such as a diaper or an incontinence garment, comprising a casing, an outer side of the casing being distal from the body of the wearer in use of the garment and an inner side being proximal to the body of the wearer in use of the garment, said casing having a front part, a rear part and a crotch part lying between the front and rear parts, the casing comprising an absorbent structure, whereby the absorbent product further comprises a fastening system, for attaching opposing side portions of the front and rear parts to each other, comprising at least two cooperating fastening elements, wherein the first element functions as a landing zone for the second element, characterized in that the first element comprises at least one skewing-preventing part, which skewing-preventing part prevents the front and rear parts to slide relative one another, as it adheres to the inner part.

According to one aspect of the present invention, there is provided a radar altimeter which utilizes a downward looking MIMO phased array to form multiple beams, covering a relatively wide sector, e.g., +/−60 degrees or thereabouts. The distance to the ground is then measured in each beam allowing the ground profile to be formed. The beams may be tilted forward to cover from about +90 degrees forward (horizontal) to about 30 degrees behind nadir. The provision of such a forward tilt gives a greater degree of coverage in the direction of approach vector to the ground. This additional cover enables the altimeter to more accurately detect other vehicles in the proximity to the current approach vector of the vehicle to the desired landing zone.

Restrictions of conventional techniques for assisting navigation of a vertical takeoff and landing vehicle in circumstances where there is a possibility of the view being obscured, can be overcome by using a three-dimensional model in combination with image processing to determine which segments of a landing zone are visible and which segments are obscured. A pilot is provided with a view of the landing zone that is a combination of live images and simulated segments from the three-dimensional model. Whereas conventional techniques focus on generating better simulated views, an implementation of this invention includes generating a view of an obscured landing zone that includes live imager. Fusing live imagery with other sensor information to generate a view allows the pilot to use a much real information as possible, and facilitates increased pilot confidence that the pilot can proceed and execute a successful landing.

A runway indicator is displayed overlying a target runway for providing supplementary guidance to support the pilot's ability to fly a stabilized approach. The highlighted runway position indicator provides cues to verify that the aircraft is continuously in a position to complete a normal landing using normal maneuvering during the instrument segment of an approach and includes a landing threshold, a landing zone on the runway, an approach line leading to the runway, an outline highlighting the sides and ends of the runway, a rectangle larger than and surrounding the runway, and a visual precision path approach indicator.

Disclosed is a perfluoropolyether (PFPE) lubricant comprising less than about 10 percent PFPE molecules having a molecular weight lower than about 2000 Daltons, and wherein the average molecular weight of the lubricant is greater than about 5000 Daltons. Such a lubricant comprises less than about 15 percent PFPE molecules having a moleuclar weight greater than about 10,000 Daltons. Also disclosed is a thin film magnetic disc comprising a recording surface and a PFPE lubricant in contact with the recording surface. The recording surface of such a thin film magnetic disc can be adapted to magnetically record information via an air bearing read/write head. The recording surface can be smooth. The disc can further comprise a rough-surfaced landing zone inward of the recording surface, wherein the PFPE lubricant is in contact with the landing zone. Also disclosed is a method of lubricating a thin film magnetic disc. The method can comprise applying a narrow, high molecular weight fractionated PFPE lubricant to the disc. In addition, a method of preparing a PFPE lubricant for use with a thin film magnetic disc is disclosed. The method can comprise fractionating a PFPE lubricant to include less than about 10 percent PFPE molecules having a molecular weight lower than about 2000 Daltons. The average molecular weight of such a lubricant after fractionation is greater than about 5000 Daltons.

A knitted fabric female fastening portion for a mechanical fastener having a knitted fabric, an underlying substrate, a bonding layer, said bonding layer having a first plurality of non-intersecting bond lines and a second plurality of non-intersecting bond lines which are combined to form a pattern of intersecting bond lines that define tessellating pattern elements.

A pneumatic tire comprises shoulder land zones and middle land zones divided by shoulder main grooves and a crown main groove. The shoulder land zone is divided by shoulder lateral grooves into shoulder blocks. The middle land zone is formed as a circumferential rib in substance. The middle land zone is provided with first and second middle outward slots which extend from the shoulder main groove toward the axially inside beyond the widthwise center line of the middle land zone, while gradually decreasing the width and inclining with respect to the tire axial direction at an angle [theta]1 and an angle [theta]2 ([theta]2>[theta]1), respectively, and terminate within the middle land zone. The open ends of the first and second middle outward slots respectively face the open ends of the shoulder lateral grooves at the shoulder main groove.

An electronic marker may provide an approach notification to enable people to understand and interpret actions by a UAV, such as an intention to land or deposit a package at a particular location. The marker may communicate a specific intention of the UAV and/or communicate a request to a person. The marker may monitor the person or data signals for a response from the person, such as movement of the person that indicates a response. The marker may be equipped with hardware and/or software configured to provide notifications and/or exchange information with a person or the UAV at or near a destination. The marker may include a display, lights, a speaker, and one or more sensors to enable the UAV to provide information, barcodes, and text. The marker can provide final landing authority and can “wave-off” the UAV if an obstacle or person exists in the landing zone.
