DETAILED DESCRIPTION

[0033] A detailed explanation of the system, method, and exemplary embodiments of the present invention are described below. Exemplary embodiments described, shown, and/or disclosed herein are not intended to limit the claims, but rather, are intended to instruct one of ordinary skill in the art as to various aspects of the invention. Other embodiments can be practiced and/or implemented without departing from the scope and spirit of the claimed invention.

[0034] Computers and radio-based devices often need to be deployed in harsh, dynamic, and unusual environments. For example, the Navy and Coast Guard increasingly use advanced computer systems and radio stations on ships that were built decades ago and in locations that make them prone to impacts and jostling. Operators can deploy systems in moving vehicles, temporary dwellings, and safe houses, none of which are ideal for computers and radio systems, which may include sensitive componentry. Accordingly, there is a need for robust and rugged systems for these and other harsh environments.

[0035] Although useful and adaptable for various computer and radio missions, embodiments can provide on-the-move force or fixed site protection against hostile sUAS. A ruggedized, mobile platform embodiment can precisely detect, identify, and/or mitigate sUAS threats via delivery of sophisticated non-kinetic, non-attributable effects. Systems can have reduced size, weight, and power requirements and can be easily deployed in space-, weight-, and power-constrained environments such as in vehicles and/or maritime vessels.

[0036] Embodiments can have protrusions, shock mounts, handles, and heat pipes that can allow computer and radio-based devices to be ruggedized and efficiently deployed. For example, some embodiments can be a housing for C-sUAS that can be installed in under one hour in a vehicle, such as a sport utility vehicle (SUV), a HUMVEE, or a maritime vessel and can allow real-time situational awareness (SA) of a hostile sUAS threat. It can be ruggedized yet light enough for a two-person lift, and it can operate under severe environmental conditions, such as large temperature ranges (0° C. to 60° C.), rain, salt spray/fog, snow, and dust. Embodiments can incorporate protrusions that prevent damage to system exterior controls during transport, installation, and operation and have flexible mounting options that can be easily adapted for various fixed site and mobile platform configurations. A versatile power system can be capable of running off vehicle power, shore power, and/or optional battery pack. Embodiments can incorporate heat pipes that reduce size, weight, and power requirements of the computer or radio-based device.

[0037] FIGS. 1-5 illustrate a chassis for an antenna interface unit (AIU, 100). The AIU chassis may include a top plate (101) and a bottom plate (not shown). The AIU chassis may include protective protrusions (102) at each of its four corners. Handles (103) can be attached to the side of the chassis at the protrusions to facilitate carrying of the AIU. FIG. 2 shows how handles (103) can be located at the outside of the protrusions to provide a distance from the AIU. FIG. 4 shows the handles attached by rivets or bolts (106). Handles (103) can provide further protection of the AIU and can be used with tie-downs to secure the AIU. The handles may include a series of slots (115) as shown in FIG. 4. The slots can be utilized with a plurality of straps, which can be fed through the slots to further secure the AIU.

[0038] Protrusions (102) can be shaped, for example as shown in FIG. 5, to facilitate sliding the AIU chassis into and out of mounting racks (not shown). The mounting rack can have a correspondingly shaped slot to accept the AIU chassis and secure the chassis from vertical and horizontal movement. The corners of the protrusions can be faceted, for example as shown in FIG. 4, to facilitate easier installation of the chassis in the mounting rack.

[0039] Shock mounts (104) can be located at various positions about the AIU chassis. The shock mounts may include bolt holes to facilitate hard mounting the AIU chassis. The AIU can be mounted in any orientation, which can allow the AIU to be located out of the way, such as vertically mounted on a wall or a ceiling, was well as in discrete or surreptitious locations. Compressible grommets can be placed between the shock mounts and the mounting surface to further protect the electronic componentry of the AIU. In an embodiment, three or more shock mounts can be utilized to secure the AIU to a vehicle. Shock mounts may include compressible grommets, springs, and/or spacers, as well as, or alternatively, hydraulic or gas springs or shocks or other vibration or shock-isolating componentry.

[0040] Interface panel (105) of the AIU can be configured according to user preference and/or specific applications and/or requirements. FIG. 3 illustrates an interface panel in an embodiment of the AIU chassis. The AIU interface panel may include a power switch or toggle (116). Lights (117) on the interface panel can indicate various status data. The lights can be general system indicators and/or indicators associated with specific ports (118). Dedicated ports (118) can be included on the interface panel for communicating according to specific standards and/or supporting peripheral devices. A port can be dedicated for powering the AIU. Other interface ports and jacks (119) can also be included.

[0041] FIG. 5 illustrates another embodiment of the AIU chassis. According to this embodiment, the interface panel may include a port for connecting to a high band antenna (107) and a port for connecting to a low band antenna (108). The chassis may include a plurality of Wi-Fi antennae. As shown, the AIU can connect to Wi-Fi Antenna 1 (109) and Wi-Fi Antenna 2 (110). The AIU can also include a port for connecting to an antenna for satellite-based geolocation. Here, GPS (Global Positioning System) is given as an example, but the system can utilize one or more other geolocation satellite systems, such as GLONASS, Galileo, BeiDou-2, and others. The AIU chassis can further include a cable or multi-cable interface connection (112), for example to facilitate communications with a computer controller. The AIU chassis may include indicator lights (113), which as an example are shown as power, status, and transmission indicators. The AIU chassis may include one or more cooling vents. As shown in the figure, the vent can be constructed of a sheet of strong material, such as metal, having a pattern of holes to allow air to vent. The vent also, or alternatively, may include a screen and/or filter. The vents may include high-flow, replaceable filter cartridges.

[0042] FIGS. 6-10 illustrate a chassis for a processor control unit (PCU, 200). The PCU chassis may include a top plate (201) and a bottom plate (not shown). The PCU chassis may include protective protrusions (202) at each of its four corners. Handles (203) can be attached to the side of the chassis at the protrusions to facilitate carrying of the PCU. FIG. 7 shows how handles (203) can be located at the outside of the protrusions to provide a distance from the PCU. FIG. 9 shows the handles attached by rivets or bolts (206). Handles (203) can provide further protection of the PCU and can be used with tie-downs to secure the PCU. The handles may include a series of slots as shown in FIGS. 6 and 9. The slots can be utilized with a plurality of straps, which can be fed through the slots to further secure the PCU.

[0043] Protrusions (202) can be shaped, for example as shown in FIG. 8, to facilitate sliding the PCU chassis into and out of mounting racks (not shown). The mounting rack can have a correspondingly shaped slot to accept the PCU chassis and secure the chassis from vertical and horizontal movement. The corners of the protrusions can be faceted, for example as shown in FIG. 9, to facilitate easier installation of the chassis in the mounting rack.

[0044] Shock mounts (204) can be located at various positions about the PCU chassis. The shock mounts may include bolt holes to facilitate hard mounting the PCU chassis. The PCU can be mounted in any orientation, which can allow the PCU to be located out of the way, such as vertically mounted on a wall or a ceiling, was well as in discrete or surreptitious locations. Compressible grommets can be placed between the shock mounts and the mounting surface to further protect the electronic componentry of the PCU. In an embodiment, three or more shock mounts and compressible grommets can be utilized to secure the PCU to a vehicle.

[0045] Interface panel (205) of the PCU can be configured according to user preference and/or specific applications and/or requirements. FIG. 8 illustrates an interface panel in an embodiment of the PCU chassis. The PCU interface panel may include a power switch and/or toggle (217) and/or one or more breakers (218, 219). Lights (227, 228) on the interface panel can indicate various status data. The interface panel lights can be general system indicators and/or indicators associated with configurable ports (226). Interface ports can be multi-pin ports (220, 221), axial ports (224), and/or multi-axial ports (222) can also be included. Other port types can be included on the interface panel, such as jacks (223, 225) and/or ports for interfacing with peripheral devices.

[0046] FIG. 10 illustrates another embodiment of the PCU chassis. According to this embodiment, the PCU chassis may include indicator lights (208), which as an example are shown as indicators of status, power from alternating current (AC), power from direct current (DC), and fault in the DC power. Power can be supplied via AC power connector at the AC circuit breaker assembly (215) and/or via DC power at the DC power input (210) at the DC circuit breaker (211). The PCU can be turned on and off via power switch (216). The PCU chassis may include one or more cooling vents (214). As shown in the figure, the vent can be constructed of a sheet of strong material, such as metal, having a pattern of holes to allow air to vent. The vents also, or alternatively, may include screens and/or filters, such as high-flow, replaceable filter cartridges. The interface panel (205) of the PCU may include a cable or multi-cable interface connection or interconnect (209), as well as Ethernet ports (213), and/or a battery monitor port (212). The interconnect can, for example, facilitate communications with an antenna interface unit.

[0047] FIG. 11 illustrates a system that may include an AIU (100) and a PCU (200). The AIU and PCU can be interconnected via interface cable (301). The interface cable can be of various lengths to facilitate on-site configuration of the AIU/PCU system. For example, the interface cable can be a meter or two, or the interface cable can be several tens of meters. The AIU can be communicatively connected to antennae (302-306). For example, in an embodiment, the AIU can be connected to high band antenna (302), low band antenna (303), a first Wi-Fi antenna (304), a second Wi-Fi antenna (305), and a GPS antenna (306). Connecting the separate units via the interface cable can allow the AIU to be placed nearer the antennae than the PCU. This can facilitate locating the PCU in a cooler and/or more protected environment than the AIU. Whether the antennae are configured to communicate according to a digital or analog protocol, the physical communications themselves are necessarily analog in nature. Accordingly, locating the AIU nearer the antennae can also facilitate handling of analog signals at the point of reception or transmission, which can improve signal quality and reduce noise. Further, communication via the interface cable can be digital, either by conversion of analog signals to digital signals by the AIU or by digital signals sent from the PCU to the AIU, whether or not for subsequent conversion to analog.

[0048] Computers and radio equipment can generate significant heat. Prior solutions can require much more space and can be less efficient than implementations disclosed herein, and such electronics and radio systems were subject to failure without air conditioning to prevent overheating. The AIU and PCU chassis can advantageously include heat-transfer devices to dissipate such heat energy without air conditioning. For example, top plate (101, 201) can be a heat sink. The back panel can also be a heat sink. FIG. 12 illustrates an AIU chassis having an alternative AIU heatsink (401) with fins. Similarly, FIG. 13 illustrates a PCU having an alternative PCU heatsink (501) with fins. Embodiments can provide important advantages in cooling electronic and/or radio systems.

[0049] In a preferred embodiment, the PCU chassis includes heat pipes, which combine thermal conductivity and phase transitions to release heat produced by processors of the PCU. FIG. 14 illustrates the interior of a PCU chassis. The high temperature end of the heat pipes (601) can be positioned so as to be in thermal contact with processors. The low temperature end of the heat pipes can be positioned so as to be in thermal contact with the back side of the chassis, as shown for example in FIG. 15. Alternatively, the low temperature end of the heat pipes can be in thermal contact with a heat sink, such as top plate (101, 201) or, alternatively, the heat sinks of FIGS. 12 and/or 13. It should be understood that heat pipes can similarly be advantageously utilized in the AIU chassis.

[0050] The heat pipes and heat sinks discussed herein can obviate the need for fans. Fans can be employed to increase the rate of heat dissipation. In another embodiment, the heat sinks of FIGS. 12 and 13 can be disposed within the chassis, i.e. under the top plate (101, 201). Fans can draw air into the chassis from vents (114, 214) and blow air through the fins of the heat sink (401, 501), and air can exit the chassis through vents in the back plate of the chassis. Fans can be similarly employed without the need for finned heat sinks. In a preferred embodiment, the AIU chassis and the PCU chassis can each further include an internal plate below top plate (101, 201). The internal plate can hermetically seal the electronic componentry within the chassis, and may include a heatsink. Vents (114, 214), as shown in FIGS. 5 and 8, can channel air through one or more ducts that can be in thermal communication with the heat sink.

[0051] The frame of the chassis (100, 200) is preferably metal, though other materials are contemplated. In a preferred embodiment, the chassis frame is constructed of aluminum or steel, which can provide both good thermal conductivity and protection from physical impacts. Portions of the system, such as the handles etc., may include material having lower conductivity, to protect nearby objects and/or persons from overheating and/or burning. In some embodiments, the frame is between three to ten millimeters in thickness. The plates of the chassis are preferably metal one to ten millimeters thick. The plates can be attached to the frame of the chassis by rivets or bolts. Alternatively, the frame and one or more plates can be constructed as a monolithic structure. An advantage of embodiments can be modularization of the chassis, which can facilitate fitting the systems in small spaces and accompanying other racks of unrelated electronic equipment. Other advantages may include protection of system controls from being damaged and/or inadvertently moved if the system is set on its side and/or impacted by persons or objects.

[0052] The chassis may include internal mounts for mounting computer and radio componentry within the chassis. The mounts can be shock mounts, including, for example, compressible dampeners and/or springs.

[0053] A C-sUAS may include non-kinetic, non-attributable (i.e., the origin of the countermeasures cannot be attributed to a specific location) countermeasures built upon a flexible software-defined radio (SDR) architecture to keep pace with the world's rapidly expanding sUAS threat environment. A C-sUAS embodiment is shown in FIG. 16. The C-sUAS may include subsystems such as an antenna subsystem, an Antenna Interface Unit (AIU), and interconnect cable, a Processor Control Unit (PCU), and a user interface, such as a laptop. The antenna subsystem can be installed, as shown, on the exterior of a vehicle, or it can be installed in the interior of a vehicle or even at a fixed site. The antenna subsystem can be connected to the antenna interface unit via RF cabling. The antenna interface unit can be connected to the processing unit through an interconnect cable. A laptop can be connected to the processing unit, for example by a standard Ethernet cable.

[0054] Embodiments can be deployed without impairment in high temperature and extreme vibration environments. The AIU and the PCU disclosed and described herein can meet and/or exceed environmental requirements of military standard MIL-STD-810G. For example, embodiments can meet temperature and humidity (0° C. to 60° C. and 5% to 95% humidity), rain (4″ per hour), ice (½″ accumulation), salt fog (48-hour exposure), shock and vibration (from rough road conditions and vessel-mounting), transit drop (transit case protection), and wind (100 mph).

[0055] All of the systems disclosed and claimed herein can be made and implemented without undue experimentation in light of the present disclosure. While the apparatus of this invention have been described in terms of preferred embodiments, it will be apparent to those of skill in the art that variations may be applied to the systems and apparatus described herein without departing from the concept, spirit and scope or the invention. In addition, from the foregoing it will be seen that this invention is one well adapted to attain all the ends and objects set forth above, together with other advantages. It will be understood that certain features and sub-combinations are of utility and may be employed without reference to other features and sub-combinations. This is contemplated and within the scope of the appended claims. All such similar substitutes and modifications apparent to those skilled in the art are deemed to be within the spirit and scope of the invention as defined by the appended claims.
