Embodiments of the present disclosure generally relate to drone deterrence systems, methods, and assemblies, such as may be used to prevent or otherwise deter drones from invading residential and/or commercial locations.
In recent years, aerial drones have become available for commercial and private use. For example, certain businesses have started, or have considered, using aerial drones to deliver products to customers. An individual may order a product from a particular provider, and an aerial drone may deliver the product to the home of the individual. As such, delivery of goods to consumers is becoming quicker and more efficient due to the use of aerial drones.
At the same time, however, aerial drones may be used by unscrupulous individuals to invade the privacy of others. A drone may be purchased by an individual and used to spy on others. For example, the drone may be flown over a yard or other such property of another and used to acquire video or images of the yard without consent. Further, the drone may be maneuvered into close proximity of a window of a residence and used to acquire images or video of the residence through the window.
In short, the use of drones has grown exponentially and will likely continue to grow in the upcoming years. Unfortunately, however, drones may also be used for unauthorized and even nefarious purposes, such as spying or otherwise invading the privacy of others.
A need exists for a system and method of deterring unauthorized use of drones. A need exists for preventing, minimizing, or otherwise reducing the possibility of a drone being used to invade the privacy of individuals.
With those needs in mind, certain embodiments of the present disclosure provide a drone deterrence system that includes a housing configured to be secured to a structure. A motion detector is disposed on or within the housing, and is configured to detect motion within a predetermined range.

The foregoing summary, as well as the following detailed description of certain embodiments will be better understood when read in conjunction with the appended drawings. As used herein, an element or step recited in the singular and preceded by the word “a” or “an” should be understood as not necessarily excluding the plural of the elements or steps. Further, references to “one embodiment” are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features. Moreover, unless explicitly stated to the contrary, embodiments “comprising” or “having” an element or a plurality of elements having a particular condition may include additional elements not having that condition.
Embodiments of the present disclosure provide drone deterrence systems and methods that are configured to prevent unauthorized use of a drone. In at least one embodiment, a drone deterrence system includes a motion detector that is configured to detect motion of a drone within a predefined distance to the drone deterrence assembly. Once a drone is detected via the motion detector, a tracker tracks the motion of the drone. A laser may then be used to prevent a sensor of the drone from acquiring video or images. For example, the laser may emit laser energy into a camera of the drone that is tracked by the tracker. In at least one embodiment, the laser and the tracker are mounted on a gimbal assembly. In at least one embodiment, once a drone is detected via the motion detector, power is supplied to all operative components of the drone deterrence system.
Certain embodiments of the present disclosure provide a drone deterrence system that includes a housing, a motion detector disposed in the housing, and a control unit disposed in the housing. The control unit is configured to receive power in response to the motion detector detecting motion within a predetermined distance to the drone deterrence system. The housing may include a dome-shaped cover coupled to a base. The motion detector may have a range of 0-150 feet, for example. Alternatively, the range may more than 150 feet. However, the range may be limited to 150 feet in order to prevent laser energy being emitted or otherwise transferred inadvertently into an aircraft (such as commercial airlines) flying more than 150 feet away.
The drone deterrence system includes a tracker that is configured to track motion of an object that has been detected by the motion detector. For example, after the motion detector senses motion, the tracker is activated to track the motion of the object. In at least one embodiment, the tracker includes a detector assembly having four detectors (such as charge-coupled devices (CCD), complementary metal oxide semiconductors (CMOS), or the like) that are able to track a source of energy (that is, a component that emits energy, such as a sensor of a camera) of a drone.
In at least one embodiment, the drone deterrence system includes a camera. The camera is powered in response to the motion detector detecting motion. When powered, the camera outputs a video signal, which may be viewed by an individual through a computing device (such as a personal computer, a laptop computer, a handheld device, or the like) that is in communication with the drone deterrence system, such as through one or more wired or wireless connections.
The drone deterrence system may also include a countermeasure that is configured to generate a disturbance that impairs the functionality of a camera of a drone. For example, the disturbance may be electromagnetic interference, optical interference, and/or the like.
The drone deterrence system may also include a laser moveably secured to an actuator, such as a flex mount, that allows laser energy to be guided to a particular point in space. The laser is controlled by the control unit to emit laser energy to the camera of the drone. The laser may be configured to impair the functionality of a camera sensor of the drone. In at least one embodiment, the laser is an example of a countermeasure.
In at least one example, the laser and the tracker are mounted to a gimbal assembly. The gimbal assembly includes one or more actuators (such as motors) that allow the laser and tracker to move in relation to one or more axes of rotation. The laser and the tracker are in communication with the control unit, such as through one or more wired or wireless connections. The control unit monitors a tracked position (for example, of a drone) output by the tracker to continually track motion of the drone. Further, the control operates the laser, based on the tracked position, to continually direct laser energy onto the drone. For example, the tracker may track a camera of the drone (such as by tracking energy emitted by the camera), and the control unit operates the laser to emit the laser energy into or onto the drone, such as into the camera of the drone. The control unit operates to track the drone and emit the laser energy in relation to the drone in a closed loop manner, as the tracker continually tracks motion of the drone and the laser continually emits the laser energy in relation to the tracked position of the drone, such as until the drone is no longer within a predetermined range of the drone deterrence system.
In at least one embodiment, the laser includes an expanding lens (such as a concave or convex lens) that expands a laser beam emitted by the laser. The expanding lens expands, spreads, or otherwise diffuses the emitted laser beam. The laser beam may be diffused to be effective to deter a drone within a predetermined range, such as within 100 feet. In this manner, the laser beam is expanded to a degree outside of the predetermined range so as not to adversely affect eyesight of pilots, for example. As such, the drone deterrence system and method may be used in airports without adversely affecting aircraft taking off and landing, for example.
The drone deterrence system may be mounted to a fixed structure, such as a building (for example, a residence). As another example, the drone deterrence system may be mounted to a vehicle, such as a land-based vehicle (for example, an automobile, bus, locomotive, military vehicle, or the like), a sea-based vehicle (such as a ship), an aircraft, a spacecraft, or the like. The drone deterrence system can be permanently mounted to a structure, or removably coupled to a structure, such as via tracks, clips, fasteners, or the like.
In at least one embodiment, the drone deterrence system may be linked to a home security system. A camera and monitor of the home security system may be used by the drone deterrence system. For example, the camera of the home security system may provide the camera for the drone deterrence system. Further, the monitor of the home security system may be or include a computing device used by the drone deterrence system.
Certain embodiments of the present disclosure provide a drone deterrence system and method that includes securing a housing to a structure, detecting motion within a predetermined range with a motion detector disposed on or within the housing, tracking motion of a drone within the predetermined range with a tracker disposed on or within the housing, and using a control unit that is in communication with the motion detector and the tracker to take action to deter the drone from remaining in the predetermined range. The method may also include using the drone deterrence system in conjunction with a home security system. In at least one embodiment, when the drone deterrence system detects movement of a drone, the home security system may alert an authority, such as police, fire personnel, other emergency services, or the like, such as when an owner of a property is not present.
The drone deterrence system 100 may be connected to a power source 115, such as through one or more wires, cables, or the like. The power source 115 may be an electrical receptacle that is configured to receive an electrical plug of the drone deterrence system 100. As such, the drone deterrence system 100 may be powered via a source of standard alternating current. In at least one other embodiment, the power source 115 may include one or more batteries coupled to and/or disposed within the housing 102. The battery or batteries may be used as a power back-up, for example.
The drone deterrence system 100 may be in communication with a computing device 116 through one or more wired or wireless connections. The computing device 116 may be a personal computer, a laptop computer, a handheld device (such as a smart phone), and/or the like that is remotely located from the drone deterrence system 100.
In at least one embodiment, the housing 102 includes a cover 118 secured to a base 120. The cover 118 may be a dome formed of polycarbonate, acrylic, a transparent plastic, glass, or the like. The base 120 may include a plastic base that may be or include a circuit board onto which various components of the drone deterrence system 100 (such as the motion detector 104, the tracker 106, the control unit 108, the countermeasure 110, the camera 112, and the laser 114) are mounted. The base 120 may also include a shield 122 on a surface that is opposite from the surface on which the components are mounted. The shield 122 may include a metallic layer (such as a metallic foil) that is configured to block electromagnetic interference from passing therethrough (so as to protect home appliances, electronic devices, and/or the like).
The motion detector 104 is disposed on or within the housing 102 and may include one or more sensors 124 that are configured to detect motion within a predetermined range. For example, the sensors 124 may be infrared sensors, ultrasonic sensors, thermal sensors, and/or the like that are configured to detect motion. The predetermined range may be a distance from the drone deterrence system 100 in which privacy is desired. For example, the predetermined range may be 50 feet. In at least one other embodiment, the predetermined range may be between 0-150 feet.
The tracker 106 is disposed on or within the housing 102 and may include one or more detectors that are configured to track motion of an object. For example, the tracker 106 may include one or more CCD, CMOS, or other such detectors that are configured to track motion of an energy source. In at least one embodiment, the tracker 106 is configured to track motion of an energy source, such as a sensor of a camera of a drone. In at least one embodiment, the tracker 106 is mounted to a gimbal assembly.
The control unit 108 is disposed on or within the housing 102 and is operatively coupled to the motion detector 104, the tracker 106, the countermeasure 110, the camera 112, and the laser 114. The control unit 108 is configured to control operation of the drone deterrence system 100. In at least one embodiment, the control unit 108 is in communication with the motion detector 104, the tracker 106, the countermeasure 110, the camera 112, and the laser 114 (such as through one or more wired or wireless connections), and is configured to take action to deter a drone from remaining in a predetermined range of the motion detector 104. For example, the control unit 108 may take action by operating the countermeasure 110 to generate a disturbance, and/or operating the laser 114 to emit laser energy into the drone, as described below. The control unit 108 is also in communication with the remote computing device 116, such as through one or more wired or wireless connections. Alternatively, the control unit 108 may be remotely located from the housing 102. For example, the computing device 116 may include the control unit 108 or another control unit that is configured to control operation of the drone deterrence system 100.
As used herein, the term “control unit,” “unit,” “central processing unit,” “CPU,” “computer,” or the like may include any processor-based or microprocessor-based system including systems using microcontrollers, reduced instruction set computers (RISC), application specific integrated circuits (ASICs), logic circuits, and any other circuit or processor including hardware, software, or a combination thereof capable of executing the functions described herein. Such are exemplary only, and are thus not intended to limit in any way the definition and/or meaning of such terms. For example, the control unit 108 may be or include one or more processors that are configured to control operation of the drone deterrence system 100.
The control unit 108 is configured to execute a set of instructions that are stored in one or more storage elements (such as one or more memories), in order to process data. For example, the control unit 108 may include or be coupled to one or more memories. The storage elements may also store data or other information as desired or needed. The storage elements may be in the form of an information source or a physical memory element within a processing machine.
The set of instructions may include various commands that instruct the control unit 108 as a processing machine to perform specific operations such as the methods and processes of the various embodiments of the subject matter described herein. The set of instructions may be in the form of a software program. The software may be in various forms such as system software or application software. Further, the software may be in the form of a collection of separate programs, a program subset within a larger program or a portion of a program. The software may also include modular programming in the form of object-oriented programming. The processing of input data by the processing machine may be in response to user commands, or in response to results of previous processing, or in response to a request made by another processing machine.
The diagrams of embodiments herein may illustrate one or more control or processing units, such as the control unit 108. It is to be understood that the processing or control units may represent circuits, circuitry, or portions thereof that may be implemented as hardware with associated instructions (e.g., software stored on a tangible and non-transitory computer readable storage medium, such as a computer hard drive, ROM, RAM, EPROM, or the like) that perform the operations described herein. The hardware may include state machine circuitry hardwired to perform the functions described herein. Optionally, the hardware may include electronic circuits that include and/or are connected to one or more logic-based devices, such as microprocessors, processors, controllers, or the like. Optionally, the control unit 108 may represent processing circuitry such as one or more of a field-programmable gate array (FPGA), application-specific integrated circuit (ASIC), microprocessor(s), and/or the like. The circuits in various embodiments may be configured to execute one or more algorithms to perform functions described herein. The one or more algorithms may include aspects of embodiments disclosed herein, whether or not expressly identified in a flowchart or a method.
As used herein, the terms “software” and “firmware” are interchangeable, and include any computer program stored in memory for execution by a computer, including RAM memory, ROM memory, EPROM memory, EEPROM memory, OTP (one time programmable) memory, and non-volatile RAM (NVRAM) memory. The above memory types are exemplary only, and are thus not limiting as to the types of memory usable for storage of a computer program.
The countermeasure 110 is disposed on or within the housing 102 and configured to generate a disturbance that is configured to impair operation of a drone camera. For example, the countermeasure 110 may be a source of electromagnetic interference (EMI) that temporarily disables operation of a drone camera. In at least one other embodiment, the countermeasure 110 may be or include one or more lasers (such as the laser 114) that are configured to generate optical interference (for example, a monochromatic optical interference pattern such as an optical veil in front of a drone camera) that prevents a drone camera from acquiring images therethrough. In at least one embodiment, the countermeasure 110 generates the disturbance for a predetermined time period, such as 5 seconds. If after the predetermined time period the motion detector 104 no longer detects motion within the predetermined range, the countermeasure 110 ceases generating the disturbance (for example, the control unit 108 controls the countermeasure 110 to cease the disturbance). If, however, there is still motion after the predetermined time period, the countermeasure 110 may continue to generate the disturbance for an additional predetermined time period and/or the laser 114 may be activated to emit laser energy into the moving object, and the process repeats. Alternatively, the drone deterrence system 100 may not include the countermeasure 110.
The camera 112 may be disposed on or within the housing 102. The camera 112 may be a digital camera that is configured to acquire video and/or images within a field of view. The camera 112 may be a CCD, CMOS, or digital camera that is configured to acquire video. The camera 112 may output the image and/or video signals to the computing device 116 (such as through one or more wired or wireless connections) so that an individual may view the images and/or video at the location of the computing device 116. In at least one other embodiment, the camera 112 may not be disposed within the housing 102. Instead, the camera 112 may be a separate and distinct camera (such as one of a security system) that is in communication with the control unit 108 and/or the computing device 116 through one or more wired or wireless connections. Alternatively, the drone deterrence system 100 may not include the camera 112.
The laser 114 (that is, a laser-emitting device) is disposed on or within the housing 102 and may include a light emitter 126 moveably secured to an actuator 128. In at least one embodiment, the laser 114 is mounted to a gimbal assembly. The control unit 108 is configured to operate the laser 114. The actuator 128 may be a flex mount that is configured to allow the light emitter 126 to be directed toward a moving target. The actuator 128 may include one or more gimbals operatively connected to one or more motors (such as one or more servo motors, electric motors, and/or the like). In other embodiments, the actuator 128 may include gears, hinges, pulleys, rotary motors, pistons, cylinders, microelectromechanical (MEM) devices, and/or the like that are configured to direct the light emitter 126 toward a target, so that laser energy emitted from the light emitter 126 impinges on the target.
In operation, power is initially supplied to the motion detector 104. If no motion is sensed by the sensor(s) 124 of the motion detector 104, power may not be supplied to the other components of the drone deterrence system 100. For example, the motion detector 104 may include a switch 125 that is triggered when the sensor(s) 124 detect motion within the predetermined range. The switch 125 sends an activation signal (such as when the switch 125 closes) to the control unit 108 to wake up, thereby activating the control unit 108 and the other components of the drone deterrence system 100. Alternatively, power may be supplied to components of the drone deterrence system 100 at all times. For example, power may be supplied to all of the components of the drone deterrence system 100 even when the motion detector 104 does not detect motion within the predetermined range.
Once motion is detected, the tracker 106 tracks the motion of the object moving within the predetermined range. The tracker 106 may focus on an energy source (that is, a source of emitted energy, such as a sensor of a camera of a drone) and follow the motion of the energy source. The tracker 106 outputs a tracking signal to the control unit 108. The tracking signal provides information to the control unit 108 regarding the motion of the object.
In response to the control unit 108 receiving the tracking signal, the control unit 108 may operate the camera 112 to acquire video of the moving object. The camera 112 outputs the video signal to the computing device 116, which allows an individual to view the moving the object. The control unit 108 may then prompt an individual to input a command through the computing device 116. The individual may input an action command, such as a laser disruption command and/or a countermeasure command, through the computing device 116. For example, the individual may view the video acquired by the camera 112 and see that the moving object is a bird or squirrel, and decide no further action is necessary. If, however, the individual sees that the moving object is a drone, the individual may input an action command. In at least one other embodiment, the control unit 108 may automatically operate without any input from an individual to take action, such as by first causing the countermeasure 110 to generate a disturbance, and after a predetermined time period (if the object is still within the predetermined range), causing the laser 114 to emit laser energy into the moving object.
The control unit 108 receives the action command from the computing device 116. The action command may include a laser disruption signal or command. In response to receiving the laser disruption command, the control unit 108 may operate the laser 114 to emit laser energy into the moving object. The control unit 108 operates the laser 114 in conjunction with the tracker 106 to emit laser energy into the tracked energy source of the moving object. For example, the emitted laser energy may be emitted into a sensor of a camera of a drone (which is tracked by the tracker 106), which prevents or otherwise impairs the camera of the drone from acquiring images or video. The emitted laser energy may be sufficient to temporarily impair the camera of the drone, such as during the time the laser energy is emitted into the sensor of the camera. Optionally, the emitted laser energy may be configured to permanently disable a camera of a drone.
The action command may include a countermeasure command or signal. In response to receiving the countermeasure command, the control unit 108 operates the countermeasure to generate a disturbance that impairs the camera of the drone. For example, the disturbance may be EMI that prevents the camera from functioning. In at least one other embodiment, the disturbance may be generated by one or more lights that generate optical interference that forms a virtual curtain through which a camera of a drone may not acquire images or video. The shield 122 blocks the disturbance from being directed behind the drone deterrence system 100 (such as into a building onto which the drone deterrence system 100 is mounted). Alternatively, the drone deterrence system 100 may not include the shield 122.
In at least one embodiment, the control unit 108 may operate the countermeasure 110 before the laser 114. For example, the control unit 108 may operate the countermeasure 110 for a predetermined period of time (such as 5 seconds). If the drone moves out of the predetermined range of the motion detector 104 within the predetermined period of time, the control unit 108 refrains from operating the laser 114. If, however, the drone is still within the predetermined range of the motion detector 104 after the predetermined range of time, the control unit 108 then operates the laser 114. Optionally, the predetermined period of time may be greater or less than 5 seconds. In at least one other embodiment, the drone deterrence system 100 may include the laser 114, but not the countermeasure 110. In at least one other embodiment, the drone deterrence system 100 may include the countermeasure 110, but not the laser 114.
In at least one other embodiment, the drone deterrence system 100 may not include the camera 112. Instead, the control unit 108 may automatically take action (such as by operating the laser 114 and/or the countermeasure, as described above) without input from an individual. For example, when the motion detector 104 detects motion within the predetermined range, the control unit 108 may automatically control the laser 114 to emit laser energy toward a source of energy of the moving object (in conjunction with the motion of the object tracked by the tracker 106), and/or the countermeasure 110 to emit the disturbance.
When the motion detector 104 no longer detects motion within the predetermined range, the control unit 108 deactivates the countermeasure 110 and the laser 114. Further, the control unit 108 may also deactivate the camera 112. In at least one embodiment, when the motion detector 104 no longer detects motion within the predetermined range, all of the components of the drone deterrence system 100 may be deactivated (for example, power may no longer be supplied) with the exception of the motion detector 104.
As shown in
In at least one other embodiment, the structure 200 may be a moving structure, such as a vehicle. For example, the drone deterrence system 100 may be mounted onto an automobile, truck, train, airplane, watercraft, or the like.
The housing 102 may be mounted to the structure, such as through one or more fasteners, adhesives, and/or the like. In at least one embodiment, the base 120 includes a three point support assembly that allows the drone deterrence system 100 to be mounted on various surfaces, such as a slanted roof of a private residence proximate to a window.
The cover 118 may be colored (such as coated with paint, covered with a reflective surface, and/or the like) to conceal the internal components of the drone deterrence system 100. The cover 118 may include a thin film coating (for example, an anti-reflection coating) such that laser energy emitted by the laser 114 is not internally reflected. For example, the cover 118 may have a coating that allows the laser energy to pass therethrough, but otherwise conceals the internal components of the drone deterrence system 100. In at least one embodiment, the laser 114 is configured to emit laser energy at a wavelength corresponding to the color green, and the cover 118 may have a coating that allows the emitted laser energy to pass therethrough. In at least one other embodiment, the cover 118 may not be colored, but may instead be clear and transparent. The inside surface of the cover 118 may be covered with an anti-reflection coating that is configured to allow laser energy emitted by the laser 114 to pass therethrough, and also conceal the components of the drone deterrence system 100 secured within the housing 102.
The drone deterrence system 100 may be contained within the housing 102, which is compact. For example, a diameter 170 of the base 120 may be 12 inches or less. The diameter of the cover 118 may be of a similar size. As such, the drone deterrence system 100 provides a compact assembly that is configured to be discretely mounted to a structure. Alternatively, the diameter 170 of the base 120 may be greater than 12 inches.
At 300, the motion detector 104 is operated to detect motion within a predetermined range. At 302, based on motion signals output from the motion detector 104, the control unit 108 determines whether or not there is movement within the predetermined range. If there is no motion within the predetermined range, the method returns to 300.
If, however, there is movement within the predetermined range, the method proceeds from 302 to 304, in which motion of the object within the predetermined range is tracked by the tracker 106. At the same time, the camera 112 may be activated to output a video signal of the moving object within the predetermined range to the computing device 116. As the motion of the object is being tracked, the control unit 108 may then activate the countermeasure 110 for a predetermined time period (such as 5 seconds) at 306.
At 308, the control unit 108 determines whether the object is still within the predetermined range, based on tracking signals output by the tracker 106 and/or motion signals output by the motion detector 104. If the object is not within the predetermined range, the method proceeds from 308 to 310, in which the countermeasure is deactivated, and the method returns to 300.
If, however, the control unit 108 determines that the object is still within the predetermined range at 308, the method proceeds from 308 to 312, in which the control unit activates the laser 114 to emit laser energy into the object. At 314, the control unit 108 then determines if the object is still within the predetermined range. If the object is still in the predetermined range, the method returns to 312 from 314.
If, however, the object is no longer within the predetermined range at 314, the method proceeds from 314 to 316, in which the laser is deactivated. The method then returns to 300 from 316. As described, the control unit 108 operates the drone deterrence system 100 through a closed loop process.
Referring to
The tracker 106 and the laser 114 are mounted to the gimbal assembly 400. Any of the embodiments of the drone deterrence system 100 described herein may include the tracker 106 and the laser 114 mounted to the gimbal assembly 400.
The gimbal assembly 400 is secured to the housing 102, such as on and/or within the housing 102. In at least one embodiment, the gimbal assembly 400 includes a first bracket 402 and a second bracket 404. The first bracket 402 includes a support panel 406 that is mounted on an outer surface 407 of the base 120. For example, the support panel 406 may be secured to the base 120 through one or more fasteners, adhesives, and/or the like. Lateral walls 408 upwardly extend from the support panel 406 at opposite ends 410. A pivot channel 412 is formed through each of the lateral walls 408.
The second bracket 404 includes a support panel 414 and lateral walls 416 upwardly extending from opposite ends 418 of the support panel 414. A pivot axle 420 extends from the support panel 414 into the pivot channel 412. The pivot axle 420 may extend through the support panel 414. Optionally, the pivot axle 420 may include two separate ends extending from opposite sides of the support panel 414. The pivot axle 420 defines a first pivot axis 424.
A portion of the second bracket 404, such as an end of the pivot axle 420, is operatively coupled to a first pivot motor 430, which may be mounted on a lateral wall 408. The first pivot motor 430 is in communication with the control unit 108, such as through one or more wired or wireless connections. The first pivot motor 430 also includes a first encoder 432, which is in communication with the control unit 108, such as through one or more wired or wireless connections. The control unit 108 is configured to control the first pivot motor 430 and determine a position of the second bracket 404 relative to the first bracket 402 via the first encoder 432.
A mount plate 440 spans between the lateral walls 416 of the second bracket 404. The mount plate 440 includes a pivot axle 442 that is pivotally retained within a pivot channel 444 of one or both of the lateral walls 416. The pivot axle 442 defines a second pivot axis 446. The first pivot axis 424 and the second pivot axis 446 are orthogonal to one another. As shown in
As described, the second bracket 404 is pivotally coupled to the first bracket 402. The second bracket 404 is configured to pivot with respect to the first bracket 402 about the first pivot axis 424. The mount plate 440 is pivotally coupled to the second bracket 404. The mount plate 440 (and therefore the tracker 106 and the laser 114) is configured to pivot with respect to the second bracket 404 about the second pivot axis 446. In at least one embodiment, the first pivot axis 424 is orthogonal to the second pivot axis 446.
A portion of the mount plate 440, such as an end of the pivot axle 442, is operatively coupled to a second pivot motor 460, which may be mounted on a lateral wall 416. The second pivot motor 460 is in communication with the control unit 108, such as through one or more wired or wireless connections. The second pivot motor 460 also includes a second encoder 462, which is in communication with the control unit 108, such as through one or more wired or wireless connections. The control unit 108 is configured to control the second pivot motor 460 and determine a position of the mount plate 440 relative to the second bracket 404 (and also with respect to the first bracket 402) via the second encoder 462.
The tracker 106 and the laser 114 are secured to an outer surface 470 of the mount plate 440, such as through one or more fasteners, adhesives, and/or the like. The tracker 106 and the laser 114 are mounted to a common structure, such as the mount plate 440. Accordingly, motion of the mount plate 440 dictates motion of both the tracker 106 and the laser 114. Alternatively, only the tracker 106 or the laser 114 may be secured to the mount plate 440.
The gimbal assembly 400 allows for motion of the tracker 106 and the laser 114 in relation to the first pivot axis 424 and the second pivot axis 446. For example, the control unit 108 controls the motion of the tracker 106 and the laser 114 by operating the motor 430 to rotate the second bracket 404 about the first pivot axis 424, and by operating the motor 460 to rotate the mount plate 440 about the second pivot axis 446. As such, the gimbal assembly 400 allows for rotational motion over two degrees of freedom, namely the first pivot axis 424 and the second pivot axis 446. In this manner, the gimbal assembly 400 allows for the tracker 106 to track motion of a drone and the laser 114 to emit laser energy over a wider range, in contrast to the tracker 106 and the laser 114 being fixed to the base 120. The first and encoders 432 and 460 allow the control unit 108 to determine the angular positions of the first pivot motor 430 and the second pivot motor 460, respectively, and therefore the angular positions of the tracker 106 and the laser 114 with respect to the first pivot axis 424 and the second pivot axis 446.
As described herein, the control unit 108 operates to determine a tracked position of a drone, as detected by the tracker 106, and operate the laser 114 in a closed loop manner. In response to the drone deterrence system 100 being activated by the motion detector 104 detecting motion within the predetermined range, the tracker 106 tracks motion of the drone, such as via energy emitted by a sensor of a camera of the drone. In response, the control unit 108 operates one or both of the first pivot motor 430 and/or the second pivot motor 460 to point the laser 114 at the tracked position of the drone. The control unit 108 then operates the laser 114 to emit laser energy into the tracked position of the drone. The control unit 108 continues to receive tracking signals from the tracker 106 to continually determine the tracked position of the drone, and operate the first pivot motor 430 and/or the second pivot motor 460 to ensure that the laser 114 continues to emit laser energy toward the tracked position of the drone. The control unit 108 continues to operate in the laser 114 in response to the tracked position of the drone (as sensed by the tracker 106) until the drone is longer within the predetermined range, as described with respect to
The drone deterrence system 100 may include more or less moveable brackets than shown. For example, the mount plate 440 may be moveably secured between the lateral walls 408 of the first bracket 402, instead of having the second bracket 404. As another example, a third bracket may be moveable (and coupled to a third pivot motor) between the lateral walls 416 of the second bracket 404, with the mount plate 440 pivotally coupled between lateral walls of the third bracket.
As described herein, in at least one embodiment, the drone deterrence system 100 includes a gimbaled platform, such as the gimbal assembly 400. One or both of the tracker 106 and the laser 114 are mounted to the gimbal assembly 400. The control unit 108 operates the tracker 106 and the laser 114 in a closed loop manner to accurately track and target a drone within a predetermined range. The gimbal assembly 400 allows the laser 114 to precisely target a tracked position of the drone. In at least one embodiment, the laser 114 may include the expanding lens 500 to limit impacts beyond a desired distance.
