The fire control electronics and command transmitter 20 sends signals 24 to the projectile 12. In one embodiment, the signals 24 are radio frequency signals. In another embodiment, the signals 24 are optical signals. As will be discussed in further detail herein, the trajectory of the projectile 12 is altered in response to the signals 24. The fire control electronics and command transmitter 20 is connected to the optical sensor and camera assembly 18. In one embodiment, the fire control electronics and command transmitter 20 is connected to the optical sensor and camera assembly 18 via a wire. In another embodiment, the fire control electronics and command transmitter 20 is wirelessly connected to the optical sensor and camera assembly 18. In this embodiment, the fire control electronics and command transmitter 20 may be at a location that is remote from the optical sensor and camera assembly 18 and the gun 16. The gun 16 is mounted to the gimbal 22. Before the projectile 12 is fired, the gimbal 22 stabilizes the gun 16 and orients the gun 16 towards the target 14.
In one embodiment, the sensor 26 may be an accelerometer. In this embodiment, the sensor 26 measures gravity by having an axis in a radial direction. As such, the sensor 26 detects a difference between upward and downward acceleration. In this embodiment, the sensor 26 outputs a maximum voltage when the projectile 12 is in the third position 3C and the sensor 26 is oriented in a downward direction. Accordingly, in this embodiment, the sensor 26 outputs a sinusoid signal 36.
In another embodiment, the sensor 26 may be an infrared (IR) photodiode. In this embodiment, the sensor 26 measures IR emissions from the ground and the sky. The sensor 26 detects a warmer IR emission when oriented toward the ground relative and a colder IR emission when oriented toward the sky as the ground produces a warmer IR emission than the sky. As such, in this embodiment, the sensor 26 outputs a maximum voltage when the projectile 12 is at the third position 3C and the sensor 26 is oriented in a downward direction. Accordingly, in this embodiment, the sensor 26 outputs a square wave signal 36.
In yet another embodiment, the sensor 26 may be a Hall effect sensor. In this embodiment, the sensor measures the magnetic field of the earth to detect a difference between an upward and downward orientation of the sensor 26. In this embodiment, the sensor 26 outputs a sinusoid signal 36. In yet another embodiment, the sensor 26 may be a pressure sensor. In this embodiment, the sensor 26 detects differences in pressure as the projectile 12 rotates. The differences in pressure cause the sensor 26 to output a sinusoid signal 36.
In yet another embodiment, the sensor 26 may be a polarized radio frequency antenna. In this embodiment, the signals 24 sent by the fire control electronics and command transmitter 20 are radio frequency signals that are polarized at a given angle of a standard Cartesian plane. The sensor 26 is polarized at the same angle as the signals 24 sent by the fire control electronics and command transmitter 20. As such, the sensor 26 captures the signals 24 and outputs a maximum voltage when sensor 26 is oriented at the same angle as the signals 24 and a maximum voltage when the sensor 26 is oriented 180° from the given angle. Accordingly, the sensor 26 outputs a sinusoid signal 36 wherein the signal 36 has a period that is half the period of the rotation of the projectile 12 since the signal is maximized at two locations.
In yet another embodiment, the sensor 26 may be an optical receiver. In this embodiment, the signals 24 sent by the fire control electronics and command transmitter 20 are optical signals that are polarized at a given angle of a standard Cartesian plane. The sensor 26 is polarized at the same angle as the signals 24 sent by the fire control electronics and command transmitter 20. As such, the sensor 26 captures the signals 24 and outputs a maximum voltage when sensor 26 is oriented at the same angle as the signals 24 and a maximum voltage when the sensor 26 is oriented 180° from the given angle. Accordingly, the sensor 26 outputs a sinusoid signal 36 wherein the signal 36 has a period that is half the period of the rotation of the projectile 12 since the signal 36 is maximized at two locations.
Other exemplary sensors are entirely possible that could function as sensor 26 to provide the signal 36 needed to identify the rotational orientation of the projectile 12. Other exemplary sensors include gyroscopes sensing movements during angular orientation and/or rotation, and rotation; altimeters sensing barometric pressure, altitude change, local pressure changes, submersion in liquid; impellers measuring the amount of air/fluid passing thereby; Global Positioning sensors sensing location, elevation, distance traveled, velocity/speed; Audio Sensors sensing local environmental sound levels; Photo/Light sensors sensing light intensity which may vary depending on rotation (i.e., counting shadows in frequency dependent intervals); and Temperature sensors sensing surrounding temperature, ambient air temperature, and environmental temperature.
The sensor 26 is connected to the operational amplifier 30. The operational amplifier 30 receives the signal 36 from the sensor 26. The operational amplifier 30 conditions the signal 36 to a standardized clock signal that can be received by a standard complementary metal-oxide-semiconductor of the logic 32. Since the operational amplifier 30 conditions the signal 36 to a standardized clock signal, the sensor 26 may be any sensor 26 that outputs an electrical signal 36 that is generated as a function of the orientation of the sensor 26. Since the signal 36 is determined as a function of the orientation of the sensor 26, and is therefore determined as a function of the rotation of the projectile 12, the clock signal is also determined as a function of the rotation of the projectile 12. The logic 32 is connected to the operational amplifier 30 and receives the clock signal from the operational amplifier 30. The logic 32 processes the clock signal thereby synchronizing the logic 32 to the rotation of the projectile 12.
In one example, the sensor 26 is an IR photodiode and the scaling factor is 360. In this example, each period of the scaled signal correlates to 1° of temporal phase of the signal 36 and the clock signal and correlates to 1° of rotation of the projectile 12. Accordingly, when the scaled signal includes 360 periods, the projectile 12 has completed one revolution. In another example, the sensor 26 is an accelerometer and the scaling factor is 180. In this example, each period of the scaled signal correlates to 2° of temporal phase of the signal 36 and the clock signal and correlates to 2° of rotation of the projectile 12. Accordingly, when the scaled signal includes 180 periods, the projectile 12 has completed one revolution.
In yet another example, the sensor 26 is an accelerometer the scaling factor is 36. In this example, each period of the scaled signal correlates to 10° of temporal phase of the signal 36 and the clock signal and correlates to 10° of rotation of the projectile 12. Accordingly, when the scaled signal includes 36 periods, the projectile 12 has completed one revolution. In yet another example, the sensor 26 is an optical receiver and the scaling factor is 18. In this example, each period of the clock signal correlates to 180° of rotation of the projectile 12. As such, each period of rotation of the scaled signal correlates to 10° of temporal phase of the signal 36 and the clock signal and correlates to 10° of rotation of the projectile 12. Accordingly, when the scaled signal includes 36 periods, the projectile 12 has completed one revolution.
Furthermore, the scaled signal includes a scaled frequency that correlates to the frequency of the clock signal. The frequency multiplier unit 32A scales the frequency of the clock signal by the scaling factor. The output scaled signal includes the scaled frequency.
In one example, the frequency of the clock signal is 300,000 revolutions per minute (rpm) or 5 kilohertz (kHz) and the scaling factor is 360. Accordingly, the frequency multiplier unit 32A outputs a scaled signal with a frequency of 1,800 kHz or 1.8 megahertz (MHz). In another example, the frequency of the clock signal is 600,000 rpm or 10 kHz and the scaling factor is 180. Accordingly, frequency multiplier unit 32A outputs a scaled signal with a frequency of 1,800 kHz or 1.8 (MHz). In yet another example, the determined period is 400,000 rpm or 6.
The counter 32B is connected to the frequency multiplier unit 32A. The counter 32B receives the scaled signal and the scaled frequency from the frequency multiplier unit 32A. The counter 32B is further connected to the operational amplifier 30. The counter 32B receives the clock signal from the operational amplifier 30. The counter 32B counts a number of maximum voltages in the scaled signal between a first maximum voltage of the operational amplifier and a second maximum voltage of the operational amplifier. That is, the counter 32B counts a number of periods of the scaled signal between periods of the clock signal. The counter 32B resets its count to 0 after each period of the clock signal or after two periods of the clock signal. Since the scaled signal correlates to the clock signal and the clock signal correlates to the signal 36 from the sensor 26 which correlates to the orientation of the sensor 26, the output count correlates to a rotation of the projectile 12.
In one example, the sensor 26 is an accelerometer and as such, the clock signal includes a maximum voltage and the count is reset when the projectile 12 is in the third position 3C. In this example, the scaled signal has a period of 144 kHz or 0.144 MHZ and the scaling factor is 36. That is, the scaled signal includes 36 periods for every rotation of the projectile 12. Hence the counter 32B counts from 0 to 36 for every rotation of the projectile 12. In this example, the counter 32B increases the count by one every 0.25 milliseconds (ms) or once every 250 microseconds (μs) as the scaled signal completes a cycle once every 0.25 ms or once every 250 μs. Accordingly, in this example, when the projectile 12 has rotated 90° from the third position 3C to the fourth position 3D, the counter 32B outputs a count of 9 2.25 ms after the counter 32B was reset.
In another example, the sensor 26 is an IR photodiode and as such, the clock signal includes a maximum voltage and the count is reset when the projectile 12 is in the third position 3C. In this example, the scaled signal has a period of 432 kHz and the scaling factor is 72. That is, the scaled signal includes 72 periods for every rotation of the projectile 12. Hence, the counter 32B counts from 0 to 72 for every rotation of the projectile 12. In this example the counter 32B increases the count by one every 0.1
In yet another example, the sensor 26 is an accelerometer and as such, the clock signal includes a maximum voltage and the count is reset when the projectile 12 is in the third position 3C. In this example, the scaled signal has a period of 1.8 MHz and the scaling factor is 360. That is, the scaled signal includes 360 periods for every rotation of the projectile 12. Hence, the counter 32B counts from 0 to 360 for every rotation of the projectile 12. In this example the counter 32B increases the count by one every 0.
In yet another example, the sensor 26 is a polarized radio frequency antenna that is polarized at 0° of a standard Cartesian plane and as such, the clock signal includes a maximum voltage and is reset when the projectile 12 is in the first position 3A. In this example the scaled signal has a period of 54 kHz and the scaling factor is 18. That is, the scaled signal includes 18 periods for every rotation of the projectile 12. Hence, the counter 32B counts from 0 to 18 for every rotation of the projectile 12. In this example, the counter 32B increases the count by one every 0.
The comparator 32C is connected to the receiving element 28. The receiving element 28 captures the signal 24 from the fire control electronics and command transmitter 20 and sends an instruction signal that is indicative of the signal 24 to the comparator 32C. The signal 24, and therefore the instruction signal, may include actuating the steering mechanism 34 when the projectile 12 has rotated to a given position. The comparator 32C is further connected to the counter 32B. The comparator 32C receives the count from the counter 32B. The comparator 32C compares the count to the instruction signal. When the count equals the position wherein the steering mechanism 34 is to be actuated, the comparator 32C outputs a command signal to actuate the steering mechanism 34.
In one example, the sensor 26 is an accelerometer. In this example, the counter 32B resets and begins counting when the projectile 12 is at the third position 3C. Furthermore, in this example, the scaling factor is 72 and the command signal includes actuating the steering mechanism 34 when the projectile 12 is at the fourth position 3D. When the count equals 18, the projectile 12 has rotated 90° from the third position 3C and is at the fourth position 3D. Accordingly, when the comparator 32C receives a count from the counter 32B that is 18, the comparator 32C outputs the command signal.
In another example, the sensor 26 is an IR photodiode. In this example, the counter 32B resets and begins counting when the projectile 12 is at the third position 3C. Furthermore, in this example, the scaling factor is 360 and the command signal includes actuating the steering mechanism 34 when the projectile 12 has rotated 227° from the third position 3C. When the count equals 227, the projectile 12 has rotated 227° from the third position 3C. Accordingly, when the comparator 32C receives a count from the counter 32B that is 227, the comparator 32C outputs the command signal.
In yet another example, the sensor 26 is an optical receiver that is polarized at 0° of a standard Cartesian plane. In this example, the counter 32B retests and begins counting when the projectile 12 is at the first position 3A. Furthermore, in this example, the scaling factor is 360 and the command signal includes actuating the steering mechanism 34 when the projectile 12 has rotated 32° from the first position 3A. When the count equals 32, the projectile 12 has rotated 32° from the first position 3A. Accordingly, when the comparator 32C receives a count from the counter 32B that is 32, the comparator 32C outputs the command signal.
The steering mechanism 34 includes an actuator and is connected to the comparator 32C. The steering mechanism 34 receives the command signal from the comparator 32C and is actuated by the actuator that moves in response to the command signal. The steering mechanism 34 may be a canard, an aileron, a piezoelectric fin, or another mechanism that alters the aerodynamics of the projectile 12. Altering the aerodynamics of the projectile 12 may alter the trajectory of the projectile 12. For example, when the steering mechanism 34 is an aileron, the command signal from the comparator 32C actuates piezoelectric transducers to raise or lower the aileron thereby creating more or less drag at a specific moment in the rotation of the projectile 12 thereby altering the trajectory of the projectile 12.
At 812, the optical sensor and camera assembly 18 observes the projectile 12 and the target 14 while the projectile 12 is in flight. Briefly turning to
At 816, the fire control electronics and command transmitter 20 generates and sends a first signal 24 to the projectile 12 to alter the actual trajectory 40 as a function of the first angle of deviation 44. The first signal 24 includes instructions to actuate the steering mechanism 34 of the projectile 12 at specific times in the rotation of the projectile 12 as described herein. Actuating the steering mechanism 34 at the specific times alters the actual trajectory 40 as a function of the first angle of deviation 44. In one example, the fire control electronics and command transmitter 20 may determine the first angle of deviation 44 is 45° relative to a standard Cartesian plane. In this example, the first signal 24 includes instructions to actuate the steering mechanism 34 at times in the rotation of the projectile 12 that will cause the projectile 12 to alter its trajectory by 45°. In another example, the fire control electronics and command transmitter 20 may determine the first angle of deviation 44 is 35° relative to a standard Cartesian plane. In this example, the first signal 24 includes instructions to actuate the steering mechanism 34 at times in the rotation of the projectile 12 that will cause the projectile 12 to alter its trajectory by 35°.
The first signal 24 may further include instructions to actuate the steering mechanism 34 of the projectile 12 as a function of a static correction that accounts for known delays when altering the trajectory of the projectile 12. The known delays may include delays in sending or receiving the first signal 24, delays in activating the steering mechanism 34, etc. If these delays are not accounted for, the trajectory of the projectile 12 may be altered in an unpredictable manner in response to the first signal 24. For example, the first signal 24 may include instructions alter the trajectory of the projectile 12 by 55°. In this example, the first signal 24 may not account for known delays and, in response to the first signal 24, the trajectory of the projectile 12 may be altered by 45°. In another example, the first signal 24 may include instructions to alter the trajectory of the projectile 12 by 65°. In this example, the first signal 24 may account for the known delays and, in response to the first signal 24, the trajectory of the projectile 12 may be altered by 65°.
At 818, the receiving element 28 of the projectile 12 captures the first signal 24 and sends the instruction signal that is indicative of the first signal 24 to the configured processor as described herein. At 820, the configured processor compares the count to the instruction signal and outputs a command signal as described herein. At 822, the steering mechanism 34 receives the command signal and actuates the steering mechanism 34 as described herein. Since the steering mechanism 34 may be actuated at any point in the rotation of the projectile 12, the steering mechanism 34 may create drag at any point in the rotation of the projectile 12. As such, the steering mechanism 34 may alter the trajectory of the projectile 12 in any direction, including up and down, in response to the signals 24.
At 824, as depicted in
At 826, the fire control electronics and command transmitter 20 determines if the second angle of deviation 50 is equal to zero. If the second angle of deviation 50 is equal to zero, then the system or method 800 proceeds to 828. If the second angle of deviation 50 is not equal to zero, then the system or method 800 proceeds to 830. At 828, the optical sensor and camera assembly 18 stops observing the projectile 12 and the projectile 12 continues towards the target 14.
At 830, the fire control electronics and command transmitter 20 generates and sends a second signal 24 to the projectile 12. The second signal 24 includes instructions to actuate the steering mechanism 34 at specific times in the rotation of the projectile 12 to alter the trajectory of the projectile 12 to the desired trajectory 42. The second signal 24 includes instructions to actuate the steering mechanism 34 of the projectile 12 as a function of a dynamic correction that accounts for the second angle of deviation 50. Accounting for the second angle of deviation 50 allows the fire control electronics and command transmitter 20 to send signals 24 that cause the projectile 12 to respond in a more predictable manner. In one example, the desired trajectory 42 may be a 45° trajectory relative to a standard Cartesian plane. In this example, after actuating the steering mechanism 34 in response to the first signal 24, the projectile 12 may be at the third location 48, wherein the third location 48 has a second angle of deviation 50 of 155°. Accordingly, the second signal 24 accounts for a 155° second angle of deviation 50. In another example, the desired trajectory 42 may be a 35° relative to a standard Cartesian plane. In this example, after actuating the steering mechanism 34 in response to the first signal 24, the projectile 12 may be at the third location 48, wherein the third location 48 has a second angle of deviation 50 of 90°. Accordingly, the second signal 24 accounts for a 90° second angle of deviation 50. After sending the second signal 24 to the projectile 12, the system or method 800 proceeds to 826. Accordingly, the system or method 800 may iteratively correct for a second angle of deviation 50. Iteratively correcting for the second angle of deviation 50 allows the system fire control electronics and command transmitter 20 to dynamically control the trajectory of the projectile 12 in a predictable manner.

Furthermore, the logic(s) may also provide specific computer implemented rules that improve on existing technological processes. The logic(s) provided herein extends beyond merely gathering data, analyzing the information, and displaying the results. Further, portions or all of the present disclosure may rely on underlying equations that are derived from the specific arrangement of the equipment or components as recited herein. Thus, portions of the present disclosure as it relates to the specific arrangement of the components are not directed to abstract ideas. Furthermore, the present disclosure and the appended claims present teachings that involve more than performance of well-understood, routine, and conventional activities previously known to the industry. In some of the method or process of the present disclosure, which may incorporate some aspects of natural phenomenon, the process or method steps are additional features that are new and useful.
The articles “a” and “an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.” The phrase “and/or,” as used herein in the specification and in the claims (if at all), should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc. As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e. “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of.” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law.
As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.
When a feature or element is herein referred to as being “on” another feature or element, it can be directly on the other feature or element or intervening features and/or elements may also be present. In contrast, when a feature or element is referred to as being “directly on” another feature or element, there are no intervening features or elements present. It will also be understood that, when a feature or element is referred to as being “connected”, “attached” or “coupled” to another feature or element, it can be directly connected, attached or coupled to the other feature or element or intervening features or elements may be present. In contrast, when a feature or element is referred to as being “directly connected”, “directly attached” or “directly coupled” to another feature or element, there are no intervening features or elements present. Although described or shown with respect to one embodiment, the features and elements so described or shown can apply to other embodiments. It will also be appreciated by those of skill in the art that references to a structure or feature that is disposed “adjacent” another feature may have portions that overlap or underlie the adjacent feature.
Spatially relative terms, such as “under”, “below”, “lower”, “over”, “upper”, “above”, “behind”, “in front of”, and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is inverted, elements described as “under” or “beneath” other elements or features would then be oriented “over” the other elements or features. Thus, the exemplary term “under” can encompass both an orientation of over and under. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. Similarly, the terms “upwardly”, “downwardly”, “vertical”, “horizontal”, “lateral”, “transverse”, “longitudinal”, and the like are used herein for the purpose of explanation only unless specifically indicated otherwise.
Although the terms “first” and “second” may be used herein to describe various features/elements, these features/elements should not be limited by these terms, unless the context indicates otherwise. These terms may be used to distinguish one feature/element from another feature/element. Thus, a first feature/element discussed herein could be termed a second feature/element, and similarly, a second feature/element discussed herein could be termed a first feature/element without departing from the teachings of the present invention.
An embodiment is an implementation or example of the present disclosure. Reference in the specification to “an embodiment,” “one embodiment,” “some embodiments,” “one particular embodiment,” “an exemplary embodiment,” or “other embodiments,” or the like, means that a particular feature, structure, or characteristic described in connection with the embodiments is included in at least some embodiments, but not necessarily all embodiments, of the invention. The various appearances “an embodiment,” “one embodiment,” “some embodiments,” “one particular embodiment,” “an exemplary embodiment,” or “other embodiments,” or the like, are not necessarily all referring to the same embodiments.
If this specification states a component, feature, structure, or characteristic “may”, “might”, or “could” be included, that particular component, feature, structure, or characteristic is not required to be included. If the specification or claim refers to “a” or “an” element, that does not mean there is only one of the element. If the specification or claims refer to “an additional” element, that does not preclude there being more than one of the additional element.
As used herein in the specification and claims, including as used in the examples and unless otherwise expressly specified, all numbers may be read as if prefaced by the word “about” or “approximately,” even if the term does not expressly appear. The phrase “about” or “approximately” may be used when describing magnitude and/or position to indicate that the value and/or position described is within a reasonable expected range of values and/or positions. For example, a numeric value may have a value that is +/−0.1% of the stated value (or range of values), +/−1% of the stated value (or range of values), +/−2% of the stated value (or range of values), +/−5% of the stated value (or range of values), +/−10% of the stated value (or range of values), etc. Any numerical range recited herein is intended to include all sub-ranges subsumed therein.
Additionally, the method of performing the present disclosure may occur in a sequence different than those described herein. Accordingly, no sequence of the method should be read as a limitation unless explicitly stated. It is recognizable that performing some of the steps of the method in a different order could achieve a similar result.
In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” “composed of,” and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases “consisting of” and “consisting essentially of” shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures.
In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed.
Moreover, the description and illustration of various embodiments of the disclosure are examples and the disclosure is not limited to the exact details shown or described.
This application claims the benefit of U.S. Provisional Application Ser. No. 62/988,678, filed on Mar. 12, 2020; the disclosure of which is incorporated herein by reference.
