A method, device, framework, and system provide the ability to control an unmanned aerial vehicle (UAV) to avoid obstacle collision. Range data of a real-world scene is acquired using range sensors (that provide depth data to visible objects). The range data is combined into an egospace representation (consisting of pixels in egospace). An apparent size of each of the visible objects is expanded based on a dimension of the UAV. An assigned destination in the real world scene based on world space is received and transformed into egospace coordinates in egospace. A trackable path from the UAV to the assigned destination through egospace that avoids collision with the visible objects (based on the expanded apparent sizes of each of the visible objects) is generated. Inputs that control the UAV to follow the trackable path are identified.

A habitat friendly, pressure conversion, wind energy extraction system is disclosed for safely extracting usable energy from wind. The system includes one or more shrouds or concentrator wings that convert the dynamic pressure of wind into relatively lower static pressure and thereby induces a vacuum that draws wind into a turbine centralized within the shrouds or concentrator wings. As such, the turbine impellor blades may be significantly smaller than the large diameter rotor blades of current popular designs and may be enclosed within the shrouds or concentrator wings that present themselves as highly visible objects and as such are easily avoided by birds in flight. The novel system in particular includes a device and method of airflow regulation than minimizes or prevents the stalling, or the generation of a turbulent flow of wind over or between the shrouds or concentrator wings. This stalling has been shown to occur when airflow is quickly accelerated by force of vacuum and drawn out of the turbine shroud which then mixes with and disturbs the otherwise smooth flow of wind over or between the shrouds or concentrator wings. The system may also include an aerobrake that responds quickly to protect the impellor blades or associated mechanisms from overspeeding or exceeding other design limitations under gusting or violent wind conditions. The system may also include a method of guiding elements of the system to orient appropriately into prevailing winds, and a method to support elements of the system, without unduly impeding the free flow of wind. Other advantages and objects are as well disclosed that increase safety and efficiency, increase installation potential, reduce costs and expenses, and minimize negative environmental impact.

A system for performing visible object determination. Visualization software running on a host processor represents space with a hierarchy of cones, and generates a hierarchy of bounding hulls from a collection of objects by recursively grouping clusters of objects. Each hull node in the hull hierarchy stores parameters which characterize a bounding hull for the corresponding cluster or object. The visualization software searches the cone and hull hierarchies starting with the root cone and the root hull. Before exploring a given cone-hull pair, a normalized cone size for the cone and a normalized hull size for the hull may be computed, and the sizes compared. If the cone size is larger than the hull size, subcones of the cone are explored with respect to the hull. Conversely, if the hull size is larger than the cone size, subhulls of the hull are explored with respect to the cone.

A system and method for performing visible object determination based upon a dual search of a cone hierarchy and a bound hierarchy performed by multiple processors. Each processor is configured to read a (global and / or local) problem queue to access a bound-cone pair. The bound-cone pair points to a bound in the bound hierarchy and a cone in the cone hierarchy. The processor computes a bound-cone distance between the bound and the cone, and compares the bound-cone distance to a visibility distance associated with the cone. If the bound-cone distance is smaller than the visibility distance, the processor may write two or more refined bound-cone pairs corresponding to a refinement of the original pair to the global or local problem queue. When the processor detects a leaf bound and a leaf cone, it updates a nearest object pointer and the visibility distance associated with the leaf cone.

An advantage of Ambisonics representation is that the reproduction of the sound field can be adapted individually to nearly any given loudspeaker position arrangement. The invention allows systematic adaptation of the playback of spatial sound field-oriented audio to its linked visible objects, by applying space warping processing as disclosed in EP 11305845.7. The reference size (or the viewing angle from a reference listening position) of the screen used in the content production is encoded and transmitted as metadata together with the content, or the decoder knows the actual size of the target screen with respect to a fixed reference screen size. The decoder warps the sound field in such a manner that all sound objects in the direction of the screen are compressed or stretched according to the ratio of the size of the target screen and the size of the reference screen.

An object editor capable of displaying a set of application software objects, which may include objects with a dynamic reflection capability (“reflective objects”), includes an object oriented configuration model instance (CMI), a generic adapter, and a UI framework. The CMI is particular to the set of application objects to be edited and defines a particular view of these objects to be provided by the editor. The CMI is external to the generic adapter and includes settings that control which application objects will be accessed and the manner of access, and in particular, which application objects will be visible, which of the visible objects' attributes will be displayed, the arrangement of displayed application objects and attributes, and the appearance of the displayed objects and attributes. The CMI is stored as a serialized XML file. The generic adapter reads the de-serialized CMI's current settings, selectively accesses the set of application objects to be edited and their attributes as dictated by the CMI settings, and passes the accessed information to the UI framework for display. The adapter uses reflection to access the attributes and associations of reflective objects. The CMI settings may be changed between editor invocations to cause objects or their attributes to be accessed and displayed differently, or not at all. The editor may be configured to edit a new set of software objects by substituting a new CMI corresponding to that set of objects. A CMI and generic adapter may be used in conjunction with applications other than an object editor, in which case the CMI settings define a manner of selectively accessing the application objects and may affect the operation of the application.

A system for performing visible object determination. Visualization software executing on one or more processors searches a cone tree with respect to a hull tree. Both trees respect the same group of transformations. Thus, the cone tree as stored in memory need not store all branches down to ultimate resolution. For example, the cone tree may store a selected cone and all its subcones down to the ultimate resolution, while subcones of other cones at the same level as the selected cone may not be represented in the stored cone tree. When the visualization software encounters a nonstored cone and a given hull H in its search procedure, the visualization software may apply an appropriate one of the group transformations to the given hull, and search the tranformed hull with respect to the selected cone (or a subcone of the selected cone).
