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.

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.

A head suspension mounts a head assembly in a disc drive. The head suspension includes controllable bending elements on the gimbal portion of the head suspension which allow dynamic control of the flying attitude of the head assemblies, and thus the flying height. In a first embodiment, the control elements are bi-metal features that utilize differential thermal expansion to control the flying attitude. In a second, and presently preferred, embodiment, the control elements are piezo-electric elements which provide bi-directional control of associated elements of the gimbal portion of the head suspension. In another aspect, the controllable bending elements are used to increase the flying height of the head assembly as the head assembly is moved from the data recording area of the disc into engagement with a textured 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.

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.

The present disclosure is directed to systems and methods for enabling unmanned and optionally-manned cargo delivery to personnel on the ground. For example, an aircraft may be used to provide rapid response cargo delivery to widely separated small units in demanding and unpredictable conditions that pose unacceptable risks to both ground resupply personnel and aircrew. Together with a ground vehicle, packages from the aircraft may be deployed to ground personnel in disbursed operating locations without exposing the ground personnel to the aircraft's open landing zone.
