FIELD OF THE INVENTION

The present invention relates to aviation equipment, in particular to means and methods for visualising images in the air, and specifically to a system and method for visualising images based on the use of controllable unmanned aerial vehicles, as well as to an unmanned aerial vehicle which may be used as part of such system and method for visualising an image.

BACKGROUND OF THE INVENTION

To date, manned and unmanned aerial vehicles with various designs and propulsion units used in the prior art for visualising images have become widely popular. In particular, known are drones, airplanes, helicopters, gliders, aerostats and other types of aircraft which are capable of performing, to one degree or another, visualisation of images in the air, in particular capable of carrying displays for displaying images, screens for projecting thereon images, various light sources for emitting light with different wavelength and/or capable of dispersing in the air various aerosols or suspensions for projecting thereon an image, and/or the like.

The unmanned aerial vehicles are advantageous over other types of aircraft which may be used to visualise an image in the air in the following: (i) possibility to accommodate such unmanned aerial vehicles in close proximity to the region of space in which it is contemplated to use these unmanned aerial vehicles for visualising images, thus allowing them to quickly occupy the appropriate spatial locations in a predetermined region of space; (ii) possibility to obtain an approval from local authorities (local administration) for use of such unmanned aerial vehicles within city limits for visualising images, for example, advertising static or dynamic images; (iii) possibility to visualise images in the air using such unmanned aerial vehicles at a small distance from the ground surface and, accordingly, viewers, thus allowing viewers to clearly see the images being visualised; (iv) less likelihood of causing serious injuries to viewers viewing the images being visualised, or threats to life of such viewers in the event of occurrence of malfunctions in the operation of such unmanned aerial vehicles, breakdowns of such unmanned aerial vehicles, or unexpected collisions of unmanned aerial vehicles to other air or ground objects; and (v) less noise pollution of the region of space in which there are visualised the images using such unmanned aerial vehicles as a result of the operation of air propulsion units thereof.

In the meantime, use of other types of air vehicles, such as, for example, airplanes, helicopters, gliders, aerostats, or the like, in some regions of space, especially in urban conditions, has significant limitations for visualising images. In particular, airplanes, helicopters and other similar aircraft require the availability of corresponding takeoff and landing areas which occupy a significant area, require obtaining a permission from local authorities for use of such air vehicles within city limits for visualising images and may be significantly removed from the region of space in which it is contemplated to visualise images using such aircraft. Furthermore, the overall dimensions of most aircraft, speed of movement thereof in the air and the noise from engines or air propulsion units thereof preclude the possibility of use thereof within city limits at a small distance from viewers observing the images being visualised using such air vehicles.

For example, US patent No. 10303415 (hereinafter US 10303415) published on May 28, 2019 describes a system for visualising an image which is comprised of unmanned aerial vehicles provided each with distinct means for visualising an image, and a control device communicatively coupled, in a wired or wireless manner, to unmanned aerial vehicles and configured to direct said unmanned aerial vehicles to a predetermined region of space so as to enable each of said directed unmanned aerial vehicles to be disposed in a predetermined spatial location to form in the air an aggregate display from said displays. It should be noted that the system for visualising an image disclosed in US 10303415 does not provide accommodation or parking of unmanned aerial vehicles used for visualising an image in close proximity to the region of space in which it is contemplated to visualise said image in the air, thus also complicating the task of delivery of unmanned aerial vehicles to said region of space, complicating the task of replacement or replenishment of the range of unmanned aerial vehicles involved in the implementation of the image visualisation process, and lengthening, in terms of time, the process of formation of an aggregate display in the air using such unmanned aerial vehicles.

Thus, the mass adoption of unmanned aerial vehicles for visualising images in a predetermined region of space, especially within city limits, requires at least to solve the urgent problem related to the storage or parking of such unmanned aerial vehicles in close proximity to the region of space (including in the region of space within city limits) in which it is contemplated to visualise an image in the air using such unmanned aerial vehicles, or to the delivery of such unmanned aerial vehicles to said region of space.

Accordingly, US patent No. 10370101 (hereinafter US 10370101) published on May 18, 2017 describes a system for visualising an image which is comprised of unmanned aerial vehicles provided each with distinct means for visualising an image, parking stations in which there are accommodated said unmanned aerial vehicles, and a control device communicatively coupled to unmanned aerial vehicles and configured to direct said unmanned aerial vehicles to a predetermined region of space so as to enable each of said directed unmanned aerial vehicles to be disposed in a predetermined spatial location to form in the air an aggregate display from said displays.

Although the system for visualising an image disclosed in US 10370101 at least partially solves the above task of storing or parking unmanned aerial vehicles used for visualising an image, said unmanned aerial vehicles according to US 10370101 are only capable of hovering in the air so as to maintain spatial positions thereof in the air and, accordingly, maintain the spatial position of the aggregate display with an image being visualised thereon, thus complicating the possibility of replacement of at least one of the unmanned aerial vehicles whose image visualisation means are involved in the visualisation of an image on the aggregate display, without deteriorating the quality of the image being visualised (in particular, for example, without temporal disappearance of at least a portion of the image being visualised, the portion corresponding to image visualisation means related to the unmanned aerial vehicle being replaced), and/or thus complicating the possibility of movement of the aggregate display in the air without deteriorating the quality of the image being visualised (in particular, for example, without temporal disappearance of at least a portion of the image being visualised, the portion corresponding to image visualisation means related to the unmanned aerial vehicles being moved, or without temporal interruption of demonstration of the image being visualised for a period of time corresponding to the time necessary for rearrangement of unmanned aerial vehicles for altering the spatial position of the aggregate display formed from the image visualisation means thereof).

Thus, the main disadvantage of the known system for visualising an image disclosed in US 10370101 is that it is possible to lose the quality of an image displayed on the aggregate display while performing replacement of at least one of the unmanned aerial vehicles whose image visualisation means are involved in image visualisation on the aggregate display, and/or in the event that there is a need to move in the air the aggregate display and, accordingly, the image being visualised on said aggregate display.

Thus, there is an obvious need for further improvement of the known systems for visualising images, in particular, for maintaining the quality of the image being visualised on the aggregate display formed from the image visualisation means of distinct unmanned aerial vehicles while movement in the air of said aggregate display and the image being visualised thereon and while replacement of at least one of said unmanned aerial vehicles.

Accordingly, the technical problem solved by the present invention is to create a system for visualising an image which at least partially eliminates at least one of the above disadvantages of the known system for visualising an image which is increased likelihood of image quality deterioration while performing replacement of at least one of the unmanned aerial vehicles whose image visualisation means are involved in visualisation of an image on the aggregate display and/or while movement of said aggregate display with an image being visualised thereon in the air.

DETAILED DESCRIPTION

Hereinafter, various exemplary embodiments of the present invention are described with reference to the accompanying drawings; however, it should be understood that the description below does not define or limit the scope of the present invention.

In the following description, a detailed description of known functions and designs will be omitted as this unimportant information may obscure the concept of the present invention.

It is to be understood that in the following description the terms such as "first", "second", "upper", "lower", "lateral", "front", "rear", etc. are used solely for convenience, and they should not be interpreted as limiting terms. In particular, as used in the present invention, unless explicitly stated otherwise in the description herein, the terms "first", "second", "third" or the like are used to distinguish elements, components, parts, assemblies, modules, blocks, embodiments, or the like, to which they pertain, from one another and not meant to describe any particular relationship therebetween. Thus, for example, it should be understood that the use of the terms "first group" of unmanned aerial vehicles and "second group" of unmanned aerial vehicles is not intended to imply any particular order, type, chronology, hierarchy or ranking (for example) of/between groups of unmanned aerial vehicles in a plurality of unmanned aerial vehicles, nor is their use (by itself) intended to imply that "third group" of unmanned aerial vehicles, "fourth group" of unmanned aerial vehicles, etc. may further exist. Further, as is discussed herein in other contexts, reference to a "first group" and a "second group" does not preclude herein the two groups from being the groups of the same elements. Thus, for example, in some instances, unmanned aerial vehicles in a "first group" of unmanned aerial vehicles and in a "second group" of unmanned aerial vehicles may coincide in terms of design, while in other cases they may be different in terms of design.

References to an item in the singular should be understood to include such items in the plural, and vice versa, unless explicitly stated otherwise or clear from the context. Grammatical conjunctions are intended to express any and all disjunctive and conjunctive combinations of conjoined clauses, sentences, words, and the like, unless otherwise stated or clear from the context. Thus, the term "or" should be understood to generally mean "and/or" and so forth.

Recitation of ranges of values herein is not intended to be limiting, referring instead individually to any and all values falling within the range, unless otherwise indicated herein, and each separate value within such a range is incorporated into the description as if it was individually recited herein.

Words "about", "approximately" or the like, when accompanying a numerical value, are to be construed as including any deviation as would be understood by one of ordinary skill in the art to operate satisfactorily for an intended purpose. Ranges of values and/or numeric values are provided herein as examples only, and do not constitute a limitation on the scope of the described embodiments.

Any and all examples provided herein, or at least a portion thereof, as well as corresponding phrases ("for example", "such as", "in particular" or the like), are used merely to facilitate understanding of the principles of the present invention and to provide for sufficient disclosure of the present invention; however, these phrases do not pose any limitations on the embodiments of the present invention, for description of which embodiments they are utilized herein, in particular they do not limit practical implementations of elements, components, parts, assemblies, modules, blocks, devices, means and/or the like utilized to disclose the principles of design and operation of the present invention.

Terms and definitions used in the description herein

The term "illustrative" means a non-limiting example, instance or illustration. In a similar manner, the terms "for example" and "by way of example" used herein set off lists of one or more non-limiting examples, instances or illustrations. As used herein, circuitry is "configured" to perform a function whenever the circuitry comprises the necessary hardware and code (if any is necessary) to perform the function, regardless of whether performance of the function is blocked or forbidden (for example, by an operator-configurable setting, factory trim, etc.).

As used in the present invention, the term "correspondence" and derivatives thereof (i.e. adjective, verb, adverb) does not necessarily mean exact conformity or exact equality in/to/between whatsoever in any respect but may imply a departure or deviation from said equality within specified limits. For example, the term "corresponding coordinates", unless the description herein clearly dictates otherwise, means not only that these coordinates may be exactly equal to one another or may exactly coincide with one another but also implies that said equality or coincidence of coordinates may be established with some error (for example, with the error of operation of a GPS system) or within the bounds of a predetermined geographic region surrounding an exact geographic point or region to which these coordinates belong, or an exact geographic location to which these coordinates belong.

As used in the present invention, the term "unmanned aerial vehicle" (UAV), unless the description herein clearly dictates otherwise, refers to an unmanned aircraft which is configured to fly or that is capable of moving by air in automatic mode, i.e. without involving a human or external control sources, or is capable of moving by air in semi-automatic mode, i.e. with receipt of at least a portion of control commands from a human (for example, a pilot, an operator, etc.) or an external source (for example, a control server or control device) via predetermined communication channels.

In one of the embodiments of the present invention, the system 500 for visualising an image may include at least one parking station 100 or one or more parking stations 100 (for example, one, two, three, four, five, six, seven, eight, nine, ten or more parking stations 100). It should be noted that in the case of using only one parking station 100 it must be configured to accommodate, park or store therein all the unmanned aerial vehicles 200 being part of the system 500. It should also be noted that in the case of using two or more parking stations 100, each of those parking stations must be configured to accommodate, park or store therein at least a predetermined portion of unmanned aerial vehicles of the plurality of unmanned aerial vehicles 200 being part of the system 500, wherein the quantity of unmanned aerial vehicles 200 accommodated in such parking stations 100, as well as shapes, sizes, types, specifications, etc. of such unmanned aerial vehicles 200, may be the same as well as different.

The parking stations 100 being part of the system 500 for visualising an image shown in Fig. 1 are intended each to accommodate, store or park therein the unmanned aerial vehicles 200. It should be noted that for visualising an image the system 500 may not use the parking stations 100 at all (in particular, it may at least partially utilize the unmanned aerial vehicles 200 present in the air at a predetermined distance from the region of space in which region it is contemplated to visualise an image, or the unmanned aerial vehicles 200 used for visualising other images in nearby regions of space that are removed from said region of space to a distance being within a threshold value), may utilize only one parking station 100, or may utilize two or more parking stations 100 (i.e., three, four, five, six, seven, eight, nine, ten or more) which are geographically removed from one another or disposed at a distance from one another and which are present within the limits of the zone surrounding the region of space in which region it is contemplated to visualise an image. For example, the parking stations 100 may be disposed at a distance of several meters, tens of meters, hundreds of meters away from one another or several kilometers away from one another. It should be noted that the geographical disposition of the parking stations 100 must enable timely replacement of one or more unmanned aerial vehicles 200, including if or when necessary to move the image being visualised in the air in various directions and over various distances in relation to the region of space in which region said image was originally or initially visualised.

One skilled in the art would readily appreciate that the quantity of parking stations 100 and mutual disposition thereof may differ depending on specific geographical locations (in particular, depending on whether the region of space in which the image is contemplated to be visualised is in open air, within or beyond city limits, or the image is formed in the interior of a building, such as in a cinema hall or in a room). In particular, in large cities there may be a need for more parking stations 100 at shorter distances from one another, as opposed to small cities, areas between cities, or other possible locations beyond city limits. In order to visualise an image in the interior of a building, there may be sufficient one parking station 100 as well as multiple parking stations 100.

Any one of the parking stations 100 shown in Fig. 1 is a stationary structure provided with compartments for accommodating therein the unmanned aerial vehicles 200.

In the given variation of the embodiment of the present invention, the control module of the unmanned aerial vehicle 200 or the control device of the system 500 may in a similar fashion enable altering of the spatial location, course of movement and/or mode of operation of said unmanned aerial vehicle 200 in the event that the distance to at least one of the detected unmanned aerial vehicles 200 is less than a predetermined threshold value, wherein such image capturing device (not shown) may be a photo camera, video camera, video recorder, video radar, and the like.

In yet another embodiment of the present invention, the fuselage 220 in each of the unmanned aerial vehicles 200 being part of the system 500 shown in Fig. 1 may be further provided with at least one robotic manipulator or grip (not shown) being under control of the control module (not shown) of said unmanned aerial vehicle 200, wherein the fuselage 210 may be further provided with an image capturing device (not shown) configured to capture images in the field of view in real time so as to enable identifying in said field of view at least one of the unmanned aerial vehicles 200 present in a predetermined spatial region and further connected to said control module so as to present thereto data relating to identified unmanned aerial vehicles, and the control module in turn may be further configured to actuate said grip in response to said data relating to identified unmanned aerial vehicles, the data being received from said grip, so as to enable performance of a detachable gripping of said identified unmanned aerial vehicle 200. It should be noted that in the given embodiment of the present invention, such image capturing device may be a photo camera, video camera, video recorder, video radar, and the like. It should also be noted that, in this embodiment of the present invention, the unmanned aerial vehicles being gripped by the grip may include the unmanned aerial vehicles 200 released from at least one of the parking stations 100 being part of the system 500 and directed to a predetermined spatial region, the unmanned aerial vehicles from parking stations being part of other system for visualising an image similar to the system 500, and/or any other unmanned aerial vehicles which may be directed to a predetermined region of space for forming a desired two-dimensional or three-dimensional object within the scope of the subject technology described herein.

In one of the embodiments of the present invention, at least two of the unmanned aerial vehicles 200 being part of the system 500 shown in Fig. 1 may be configured to mechanically connect to one another to form an aggregate unmanned aerial vehicle. Such aggregate unmanned aerial vehicles are configured each to detachably interact with one another and/or with at least one of the rest of the unmanned aerial vehicles 200. It should be noted that such aggregate unmanned aerial vehicle (not shown) formed from several unmanned aerial vehicles 200 mechanically connected to one another may be originally accommodated in a linked or docked state in one of the parking stations 100 or may be from distinct unmanned aerial vehicles 200 directed from the corresponding parking stations 100 to a predetermined spatial region. It should be noted that the unmanned aerial vehicles 200 forming such aggregate unmanned aerial vehicle (not shown) may be mechanically connected to one another in a horizontal plane and/or vertical plane to form an aerial structure of connected to one another unmanned aerial vehicles 200 which has any shape and geometric dimensions suitable for the interaction of such aggregate unmanned aerial vehicle (not shown) with at least one other similar aggregate unmanned aerial vehicle and/or with at least one distinct unmanned aerial vehicle 200 which are suitable for free movement of such aggregate unmanned aerial vehicle (not shown) in one of the parking stations 100 and which are suitable for free movement of such aggregate unmanned aerial vehicle (not shown) by air individually or as part of a two-dimensional or three-dimensional object used for image visualisation. Such aggregate unmanned aerial vehicle (not shown) may respond to control commands/instructions as integral whole, i. e. the operation of unmanned aerial vehicles 200 in such aggregate unmanned aerial vehicle may be synchronized (for example, using the control device of the system 500 or the control module of one of the unmanned aerial vehicles 200 forming such aggregate unmanned aerial vehicle). Furthermore, the unmanned aerial vehicles 200 forming such aggregate unmanned aerial vehicle (not shown) may be electrically connected to one another to form a single power supply circuit and an aggregate power source (for example, the aggregate power source may be formed from batteries of connected to one another unmanned aerial vehicles 200) supplying power to or powering all said unmanned aerial vehicles 200 substantially simultaneously, thus making it possible to consider the range not of each such unmanned aerial vehicle 200 individually but rather the range of an aggregate unmanned aerial vehicle (not shown) as a whole. It should also be noted that the process of mutual mechanical connection of the unmanned aerial vehicles 200 may be started or launched in response to control commands presented by the control device of the system 500 for visualising an image or the control module of one of the unmanned aerial vehicles 200 forming such aggregate unmanned aerial vehicle to said unmanned aerial vehicles 200. Furthermore, mutual mechanical connection between the unmanned aerial vehicles 200 forming the aggregate unmanned aerial vehicle (not shown) may be implemented immediately between the housings or bodies of the unmanned aerial vehicles 200 to be connected as well as by means of a connecting structure (not shown) with which there may be secured together or connected said unmanned aerial vehicles 200 to be connected (for example, using fastening or connecting means known in the prior art) and which said unmanned aerial vehicles 200 to be connected are collectively capable of carrying by air. Such connecting structure may be configured in the form of a ground structure to which the unmanned aerial vehicles 200 to be connected to one another may be secured or connected while presence thereof on the ground surface, wherein said connecting structure may be configured expandable or deployable, thus allowing said unmanned aerial vehicles 200 to expand or deploy said connecting structure on the ground surface as well as in the air while application thereto the tractive forces from the unmanned aerial vehicles 200. Furthermore, such connecting structure may be configured in the form of an aerial structure which is configured to independently move or fly in the air and to which the unmanned aerial vehicles 200 to be connected to one another may be secured or connected while presence thereof in the air, wherein said connecting structure may be configured expandable or deployable, thus allowing said unmanned aerial vehicles 200 to expand or deploy said connecting structure in the air while applying thereto the tractive forces from the unmanned aerial vehicles 200.

It should also be noted that the above aggregate unmanned aerial vehicle (not shown) may be formed from unmanned aerial vehicles 200 accommodated in at least one parking station of the parking stations 100 being part of the system 500, unmanned aerial vehicles 200 directed to a predetermined spatial region from at least one of the parking stations 100 being part of the system 500, unmanned aerial vehicles 200 being present in a predetermined spatial region as part of a two-dimensional or three-dimensional object used for visualising an image, and/or unmanned aerial vehicles released from at least one of the parking stations being part of at least one other system for visualising an image similar to the system 500.

When discharged, the aggregate unmanned aerial vehicle (not shown) being part of the formed two-dimensional or three-dimensional object used for image visualisation may be replaced with other (charged) aggregate unmanned aerial vehicle in the course of image visualisation or in the course of accommodation of said discharged aggregate unmanned aerial vehicle in one of the parking stations 100. While replacing a discharged aggregate unmanned aerial vehicle (not shown) with a charged aggregate unmanned aerial vehicle, said discharged aggregate unmanned aerial vehicle may be directed to one of the parking stations 100 to be accommodated therein or thereon so as to enable further storage in said parking station 100 and/or to enable replenishment of the range of such aggregate unmanned aerial vehicle. Alternatively, while replacing a discharged aggregate unmanned aerial vehicle (not shown) with a charged aggregate unmanned aerial vehicle, the unmanned aerial vehicles 200 being part of said discharged aggregate unmanned aerial vehicle (not shown) withdrawn from a two- dimensional or three-dimensional object formed in the air in a predetermined spatial region may be removed from interaction with one another (i.e., they may fly away from one another so as to unform such aggregate unmanned aerial vehicle into distinct unmanned aerial vehicles 200) so as to enable direction of each of same to one of the parking stations 100, thus allowing to accommodate the discharged unmanned aerial vehicles 200 in the parking stations 200 so as to enable further storage thereof in those parking stations 100 and/or enable replenishment of the range of at least one of those unmanned aerial vehicles 200.

First embodiment of unmanned aerial vehicle

Fig. 2 is a schematic view of one of illustrative embodiments (first embodiment) of an unmanned aerial vehicle in the form of which there may be implemented each of the above unmanned aerial vehicles 200 used in the system 500 for visualising an image shown in Fig. 1.

The unmanned aerial vehicle 200 shown in Fig. 2 comprises a fuselage 210 and two propulsion units 220 installed or secured on the fuselage 210 and is provided with a display device or display 230 which is configured to display a static or dynamic image and is communicatively connected to the control module (not shown) of the unmanned aerial vehicle 200 which in turn is configured to establish a connection so as to enable exchange of data with the above control device (not shown) being part of the system 500, wherein said control module is further configured to control the operation of the display 230, including in response to data or control instructions received from the control device of the system 500.

In one of the embodiments of the present invention, the unmanned aerial vehicle 200 shown in Fig. 2 may be provided with at least one display 230, in particular it may be provided with two, three, four, five, six, seven, eight, nine, ten or more displays 230 configured each to display a static or dynamic image when turned on or actuated, wherein said displays 230 may be secured on the fuselage 210 such that there are no interspaces therebetween or that they are disposed at a predetermined distance from one another. It should be noted that in such embodiment of the present invention, the displays 230 in each unmanned aerial vehicle 200 shown in Fig. 2 may be disposed coplanar with one of the sides of the fuselage 230, may be disposed at an angle with respect to one another on one of the sides of the fuselage 230, or may be disposed on different sides of the fuselage 230.

While directing the unmanned aerial vehicles 200 according to Fig. 2 to a predetermined spatial region, the control device of the system 500 which control device controls the operation of those unmanned aerial vehicles 200 by way of presenting control and/or navigation commands to the control modules thereof enables disposition of each of said directed unmanned aerial vehicles 200 in a predetermined spatial location in accordance with a predetermined model of arrangement of unmanned aerial vehicles (described above) known to the control device of the system 500 to form in the air at least one aggregate display 300 shown in Fig. 1 of the displays 230 each of which corresponds to one of those unmanned aerial vehicles 200, wherein said formed aggregate display 300 is substantially one of specific embodiments of the above two- dimensional or three-dimensional object formed in the air while implementing the above system 500 for visualising an image. Thus, in a given spatial region in the air there may be parallelly or sequentially formed two or more composite displays 300 using the displays 230 being part of the unmanned aerial vehicles 200 directed by the control device of the system 500 from the corresponding parking stations 100 to said spatial region.

In one of the embodiments of the present invention, the unmanned aerial vehicles 200 whose displays 230 are used to form the aggregate display 300 may be disposed in the air in predetermined spatial locations thereof corresponding to a specific model of arrangement of unmanned aerial vehicles such that said displays 230 may be disposed at a distance from one another (i.e. to form interspaces therebetween in which there is precluded the possibility of image visualisation) or may be disposed immediately adjacent to one another to form a generally continuous showing or displaying region for image visualisation.

In another embodiment of the present invention, the unmanned aerial vehicles 200 whose displays 230 are used to form the aggregate display 300 may be disposed in the air in predetermined spatial locations thereof corresponding to a specific model of arrangement of unmanned aerial vehicles such that said displays 230 may form in the air a substantially two- dimensional aggregate display 300 in which the unmanned aerial vehicles 200 are present in one and the same plane and which generally has the shape of a known two-dimensional geometric object (for example, shape of a rectangle, square, triangle, trapezoid, parallelogram, circle, oval, or the like) or any other suitable two-dimensional shape, or a three-dimensional display that generally has the shape of a known three-dimensional geometric object (for example, a cube, pyramid, parallelepiped, sphere, or the like) or any other suitable three-dimensional shape.

In yet another embodiment of the present invention, the unmanned aerial vehicles 200 whose displays 230 are used to form the aggregate display 300 may be disposed in the air in predetermined spatial locations thereof corresponding to a specific model of arrangement of unmanned aerial vehicles such that said displays 230 may form in the air an aggregate display 300 having any curvilinear shape, concave shape, convex shape, irregular shape, or the like.

In some other embodiment of the present invention, the unmanned aerial vehicles 200 whose displays 230 are used to form the aggregate display 300 may be disposed in the air in predetermined spatial locations thereof corresponding to a specific model of arrangement of unmanned aerial vehicles such that said displays 230 forming in the air the aggregate display 300 are displaced in space with respect to one another along at least one of the three coordinate axes (x, y, z), for example along one of the two coordinate axes corresponding to the vertical and horizontal axes, or along the both of those coordinate axes simultaneously so that the aggregate display 300 may have a concave shape, a convex shape, an irregular shape, or a curvilinear shape.

In some embodiments of the present invention, each of the unmanned aerial vehicles 200 may be further configured to present, in real time, data relating to the operation of the display 230 thereof to the control device of the system 500 so as to enable replacement thereof with at least one other unmanned aerial vehicle 200 being part of the system 500 from at least one of the parking stations 100 being part of the system 500 in the event of a breakdown or failure of said display 230, wherein said process of replacement may be substantially performed similar to the above process of replacement of a discharged unmanned aerial vehicle 200 with a charged unmanned aerial vehicle 200.

Each of the displays 230 in the unmanned aerial vehicles 200 may be one of a group of displays comprising: an LCD display, LED display, OLED display, AMOLED display, DLP display, TFT display, IPS display, TN display, STN display, CSTN display, FSTN display, DSTN display, DLP display, TFD display, LTPS display, UFB display, CRT display, PDP display, laser display, and the like.

The control device (not shown) of the system 500 is configured to present data relating to an image to the unmanned aerial vehicles 200 which have been directed to a predetermined spatial region and whose displays 230 are used to form the aggregate display 300 so as to enable displaying of the image 400 at least on a portion of said aggregate display 300. It should be noted that depending on the predefined features or parameters of the image 400, it may be displayed on the entire showing or displaying region of the aggregate display 300, the region being formed by all displays 230 being part of the aggregate display 300, as well as only on a portion of the showing or displaying region of the aggregate display 300 formed by a portion of the displays 230 being part of the aggregate display 300. In one of the embodiments of the present invention, the control device (not shown) of the system 500 may be further configured to present navigation commands to the unmanned aerial vehicles 200 whose displays 230 form the aggregate display 400 for the collective movement of said unmanned aerial vehicles 200 in the air so as to maintain a predetermined model of arrangement of unmanned aerial vehicles, thus allowing to uniformly move in the air the formed image 400 in the air without deforming same or degrading the quality thereof.

Each image 400 which may be visualised on the aggregate display 300 may be brought into accordance with a specific model of arrangement of unmanned aerial vehicles. In particular, the image 400 being visualised may be defined automatically depending on a predefined or user- selected model of arrangement of unmanned aerial vehicles and/or a predefined or user-selected spatial region in which it is desired to visualise said image 400. Alternatively, the image 400 to be visualised on the aggregate display 300 may be user-selected or defined separately from the region of space in which it is desired to visualise the image and/or separately from the model of arrangement of unmanned aerial vehicles, in particular using, for example, the above user device. It should be noted that the image 400 which is to be visualised on the aggregate display 300 and which the control device of the system 500 presents as part of data relating to the image to the control modules of the unmanned aerial vehicles 200 whose displays 230 form the aggregate display 300 may be preliminarily loaded or recorded by the operator into a local database being part of the control device of the system 500, or may be transferred as a data packet from an external source of data (for example, from a web-site, database, data server, and the like) via a wireless data transfer channel established between the control device of the system 500 and that external data source in response to a request of the control device of the system 500 which request, in turn, may be generated, for example, in response to a request of the user device using which the user may select said image in the list of selectable images which may be visualised on the aggregate display 300.

The image 400 displayed on the aggregate display 400 may be a still or static image (for example, a photograph, drawing, picture, and the like). Furthermore, the image 400 displayed on the aggregate display 400 may be a motional or dynamic image (for example, a clip, presentation, video film, animated image, and the like). Furthermore, the image 400 displayed on the aggregate display 400 may be any combination of a static image and a dynamic image.

The image 400 displayed on the aggregate display 400 may be a two-dimensional image, a three-dimensional image, or a combination thereof, wherein such two-dimensional or three- dimensional image may be at least partially motional.

Furthermore, the image 400 may be a combination or a mix of multiple distinct or identical individual images, wherein a portion of said individual images may correspond to the main image, and the remaining portion of said individual images may correspond to the background for said main image.

As shown in Fig. 1, the unmanned aerial vehicles 200 whose displays 230 form the aggregate display 300 form one movable string of unmanned aerial vehicles, in which string said unmanned aerial vehicles 200 move one after another along a predetermined trajectory, wherein the beginning of said movable string corresponds to the entry point of an unmanned aerial vehicle 200 into the plurality of unmanned aerial vehicles forming the aggregate display 300 (for example, in the course of initially forming said aggregate display 300, in the course of adding a new unmanned aerial vehicle 200 for altering the shape or dimensions of the aggregate display 300 or in the course of replacing a discharged unmanned aerial vehicle 200 with a charged unmanned aerial vehicle 200), and the end of said string corresponds to the exit point of an unmanned aerial vehicle 200 from the plurality of unmanned aerial vehicles forming the aggregate display 300 (for example, in the course of unforming said aggregate display 300, in the course of removing an unmanned aerial vehicle 200 for altering the shape or dimensions of the aggregate display 300, or in the course of directing a discharged unmanned aerial vehicle 200 to one of the parking stations 100).

In particular, as shown in Fig. 1, the unmanned aerial vehicles 200 whose displays 230 form the aggregate display 300 form a predetermined number of sequentially disposed horizontal or vertical rows (i.e., an array of unmanned aerial vehicles 200) in each of which the unmanned aerial vehicles 200 perform movement one after another towards the end of the row so as to enable transition to a next row upon reaching the end of a previous row, wherein, upon reaching the end of the last row (i.e., the final position in the last row) corresponding to the exit point, the control device of the system 500 enables direction of each unmanned aerial vehicle 200 to one of the parking stations 100, and, simultaneously with the exiting of an unmanned aerial vehicle 200 through the exit point, the control device of the system 500 enables disposition of another unmanned aerial vehicle directed to a predetermined region of space, in which region there is formed said aggregate display 300, from one of the parking stations 100, at the beginning of the first row corresponding to the entry point. It should be noted that the control module of the unmanned aerial vehicle 200 or the control device of the system 500 enables turning on of the display 230 related to said unmanned aerial vehicle 200 at the moment of time when said unmanned aerial vehicle 200 occupies the initial position in the movable string thereof while entering through the entry point, and enables turning off of said display 230 at the moment of time when said unmanned aerial vehicle 200 exits from the movable string thereof through the exit point. Furthermore, as shown in Fig. 1, the unmanned aerial vehicles 200 with replenished range may take off from the corresponding parking stations 100 being part of the system 500 substantially simultaneously or sequentially at short intervals of time to form in the air a group of two, three, or more unmanned aerial vehicles, wherein the control device of the system 500 enables a sequential line-up of unmanned aerial vehicles 200 with replenished range from said group into a string of unmanned aerial vehicles with replenished range, the string being directed to the entry point to the plurality of unmanned aerial vehicles forming the aggregate display 300 in a predetermined region of space.

Furthermore, as shown in Fig. 1, the unmanned aerial vehicles 200 to be replaced (i.e., the unmanned aerial vehicles 200 with insufficient range or discharged unmanned aerial vehicles 200) may sequentially fly out of a plurality of unmanned aerial vehicles forming the aggregate display 300 in a predetermined region of space through the exit point sequentially at predetermined intervals of time to form in the air a string of unmanned aerial vehicles to be replaced, the string being directed towards the parking stations 100 being part of the system 500, wherein, upon approaching said parking stations 100, the unmanned aerial vehicles 200 of said string of unmanned aerial vehicles to be replaced may exit that string to form a group of two, three or more unmanned aerial vehicles, wherein the control device of the system 500 enables substantially simultaneous or sequential direction of the unmanned aerial vehicles 200 to be replaced from said group to the corresponding parking stations 100 with free or unoccupied charging devices.

In one of the embodiments of the present invention, the unmanned aerial vehicles 200 whose displays 230 form the aggregate display 300 may form one or more movable strings of unmanned aerial vehicles (for example, two, three, four, five, six, seven, eight, nine, ten and more such strings of unmanned aerial vehicles) in each of which strings said unmanned aerial vehicles 200 move one after another along a predetermined trajectory, wherein each of said movable strings may have a beginning thereof corresponding to the entry point of an unmanned aerial vehicle 200 into said movable string and an exit thereof corresponding to the exit point of an unmanned aerial vehicle 200 from said movable string. It should be noted that in one of the variations of such embodiment of the present invention, at least a portion of the movable strings of unmanned aerial vehicles may have a common entry point and/or exit point. In these embodiments of the present invention, the movable strings of unmanned aerial vehicles may partially intersect with one another as well as not intersect with one another, wherein said movable strings may be combined with one another such that the displays 230 being part of those movable strings of unmanned aerial vehicles and forming the aggregate display 300 may provide for displaying an integral image 400 (i.e., without any darkened interspaces between different portions of the image 400), may provide for displaying the image 400 with darkened interspaces between different portions of the image 400, or may provide for two or more identical or different images similar each to the image 400.

In another embodiment of the present invention, the control device of the system 500 may be further configured to stop the movable string of unmanned aerial vehicles for a predetermined period of time (for example, one, two, three, five, ten seconds) sufficient for the emergency withdrawal of at least one of unmanned aerial vehicles 200 forming said movable string at a place or point of that movable string corresponding to the current spatial location of said at least one unmanned aerial vehicle 200 and different from the above entry point and exit point in the event of receipt, from at least one unmanned aerial vehicle 200, of data relating to a breakdown or malfunction of the display 230, early exhaustion of the range, a rapid decrease in the range, a breakdown or malfunction of at least one of the propulsion units 220, problems of the software control system of an unmanned aerial vehicle 200, unexpected collision of an unmanned aerial vehicle 200 with another object, and/or the like.

In another embodiment of the present invention, each of the unmanned aerial vehicles 200 used to form the aggregate display 300 may be provided with two displays, each of which may be similar to the above display 230 and which may be disposed on said unmanned aerial vehicle 200 such that they face opposite directions relative to one another, wherein, while forming the aggregate display 300, one of said displays 230 may form one of the two opposite sides of the aggregate display 300, and the other one of said displays 230 may form the other side of the aggregate display 300. In such embodiment of the present invention, the control device of the system 500 may enable displaying of one and the same image 400 from the both sides of the aggregate display 300, displaying of the image 400 only from one side of the aggregate display 300, or displaying of different images 400 on the opposite sides of the aggregate display 300.

In yet another embodiment of the present invention, each of the unmanned aerial vehicles 200 used to form the aggregate display 300 may be provided with two or more displays, each of which may be similar to the above display 230 and which may be disposed on said unmanned aerial vehicle 200 such that they face different directions relative to one another, whereby, while forming the aggregate display 300, each of said displays 230 may define one of the sides of the composite display 300. In such embodiment of the present invention, the control device of the system 500 may enable displaying of one and the same image 400 from different sides of the aggregate display 300, displaying of the image 400 only from one side of the aggregate display 300, or displaying of different images 400 on different sides of the aggregate display 300. According to one of the embodiments of the present invention, the unmanned aerial vehicles 200 whose displays 230 form the aggregate display 300 may form a predetermined quantity of sequentially disposed horizontal or vertical rows in each of which the unmanned aerial vehicles 200 may perform movement one after another towards the end of the row so as to enable return to the beginning of said row in case of going beyond the limits thereof of said end of the row, wherein the unmanned aerial vehicles 200 moving one after another and the corresponding returning unmanned aerial vehicles define a distinct closed string of unmanned aerial vehicles, and the control device of the system 500 enables displaying of the corresponding portion of the image 400 on the displays 230 of the unmanned aerial vehicles moving one after another and enables turning off or darkening of the displays 230 of the returning unmanned aerial vehicles 200. In other words, the unmanned aerial vehicles 200 moving one after another substantially correspond to the visible portion of the movable string (i.e., the displays 230 are turned on), and the corresponding returning unmanned aerial vehicles 200 substantially correspond to the invisible portion of the movable string (i.e., the displays 230 are turned off or darkened). It should be noted that the unmanned aerial vehicles 200 with turned off or darkened displays 230 may return to the beginning of rows thereof from that side of the aggregate display 300 which is not enabled to display the image 400, wherein, once the unmanned aerial vehicle 200 enters through the entry point the beginning of row thereof, then the controller of the system 500 enables turning on of the display 230 thereof so as to provide for displaying thereon the corresponding portion of the image, and once the unmanned aerial vehicle 200 exits the end of row thereof through the exit point, then the control device of the system 500 enables turning off of the display 230 thereof (i.e., the display 230 ceases participation in displaying of the image 400 or a portion thereof till the moment of entry of that unmanned aerial vehicle 200 into the beginning of row thereof through the entry point).

In the position (A) in Fig. 1, each of the unmanned aerial vehicles 200 being part of the system 500 is accommodated for the purpose of parking or replenishing the range in a corresponding one of the parking stations 100 being part of the system 500 and awaits the receipt of navigation and/or control commands from the control device being part of the system 500. The position (A) substantially corresponds to the starting point of movement by air or flight of said unmanned aerial vehicle 200 and corresponds to the beginning of a cycle of movement by air or flight of such unmanned aerial vehicle 200.

In the position (B) in Fig. 1, which each of the unmanned aerial vehicles 200 being part of the system 500 may take after being present in the position (A) in response to navigation commands of the control device of the system 500, which, in turn, may be generated, for example, in response to a request of the user device, the unmanned aerial vehicles 200 with a full range (if used for the first time in the given cycle) or a replenished range (if used repeatedly in the given cycle) in a required quantity corresponding to a predetermined model of arrangement of unmanned aerial vehicles and sufficient for forming an image 400 are released from the corresponding parking stations 100, wherein the departure of the unmanned aerial vehicles 200 from one and the same parking station 100 may be performed sequentially, and the departure of unmanned aerial vehicles 200 from distinct parking stations 100 may be performed substantially simultaneously), thus causing formation in the air, in a region of space located at some distance from the parking stations 100, of a group of two, three or more unmanned aerial vehicles (see.
