DETAILED DESCRIPTION

[0025] FIG. 1 shows an embodiment of a security barrier 10. The security barrier 10 includes a base 15 and a tower 16 extending upward from the base 15. In the following description, unless otherwise indicated, directional terms, such as above, below, up, down, etc. are with reference to the orientation of structure shown in the figures, and down is considered to be aligned with gravitational forces. For purposes of illustration, some dimensions may be exaggerated. The security barrier 10 includes a security hood 100. In some embodiments, the security hood 100 may be integrated directly with the tower 16 of the security barrier 10. In some embodiments, the security hood 100 may be shaped to be received upon the top 17 of the tower 16 of the security barrier 10. By way of example, the security hood 100 may be operable to be received upon the top of a security barrier as shown in U.S. Pat. No. 10,385,526 by Jacob Caval, titled Security Barrier and Methods, which is incorporated herein by reference in its entirety.

[0026] The top 17 of the tower 16 is shaped complementary to a bottom 104 of the security hood 100. For instance, the top 17 of the tower 16 of the security barrier 10 may have a top opening with a rectangular profile and the security hood 100 may include a bottom 104 that has a rectangular profile so that it may be received within the top opening.

[0027] The security hood 100 includes a body 109 to protect and house electrical components of the security hood 100. The security hood 100 may include a communications system 170 and control module 160 (shown in FIG. 3) that is contained within the body 109. The body 109 includes a front 101, a bottom 104, and a top 105 opposite the bottom 104. The body 109 may include a plurality of sides 103, including the front 101. The plurality of sides 103 includes a rear side 102 opposite the front 101. The top 105 extends between the plurality of sides 103. The front 101 and/or the plurality of sides 103 may be sloped between the bottom 104 to the top 105. The front 101 and/or the plurality of sides 103 may be sloped from the bottom 104 to the top 105. The sloped surface may be advantageous to deflect projectiles that are forced into contact with the security hood 100. The body 109 of the security hood 100 may be formed of a suitable material for its application, such as aluminum, metal, wood, plastic, or fiberglass. For riot applications, it may be desirable to use, for example, 0.25 inch (6.35 mm) or thicker steel.

[0028] As shown in FIG. 2, the rear side 102 may include one or more rear hatches 107 for providing access into the security hood 100. The top 105 may include a top hatch 106 to provide access into the security hood 100. The top hatch 106 may provide access to an anchor on the tower 16 (shown in FIG. 1) in order to lift and move the security barrier 10. The top hatch 106 may also include a mount for connecting additional equipment, such as defense systems 150 (shown in FIG. 1) to the top 105 of the security hood 100. A plurality of openings 108 may be positioned on the body 109 of the security hood 100 to provide space for mounting audio and/or visual components. The openings 108 may be of a sufficient depth for the audio and/or visual components to be recessed so that they are mounted without extending beyond the outer surface of the body 109 of the security hood 100. Preferably, the audio and/or visual components may be recessed at least 0.125 inches (3.175 mm) from the outer surface of the body 109 of the security hood 100.

[0029] Referring again to FIG. 1, the security hood 100 includes one or more lights operable to flash in a predetermined pattern of colors, speeds, and/or combinations. The lights may include white, amber, red, blue, purple, or a combination thereof. Purple lights may be preferential to communicate warnings that are not typically associated with emergency services. For instance, purple lights are used in funeral processions and may be used on a security barrier 10 to communicate that lethal force may be used beyond the security barrier 10. The lights may be used to communicate directions and/or to disorient persons in the vicinity of the security barrier 10. The one or more lights include a light bar 110 and/or a plurality of perimeter lights 120 distributed around a perimeter of the security hood 100.

[0030] At least one of the perimeter lights 120 may be positioned on the front 101 and each of the plurality of sides 103. The perimeter lights 120 are operable to flash in a predetermined pattern of colors, speeds, and/or combinations. Each of the perimeter lights 120 may include at least two light colors. The perimeter lights 120 may be recessed within the body 109 of the security hood 100 to inhibit damages from projectiles, such as projectiles thrown by rioters. In some embodiments, the perimeter lights 120 may have a width of six inches or less. It may be advantageous to limit the surface area of the perimeter lights 120 to reduce a likelihood of contact with projectiles.

[0031] The security hood 100 may include a light bar 110. The light bar 110 may be oriented towards the front 101 of the security hood 100. The light bar 110 may extend along the top 105 of the security hood 100. In some embodiments, the light bar 110 may be recessed into the front 101 of the security hood 100. A guard 115 may partially enclose the light bar 110 and/or display 130 to prevent projectiles from damaging the light bar 110 and/or display 130. For instance, the guard 115 may cover the top of the light bar 110 such that a projectile, such as a Molotov cocktail, that lands upon the top 105 of the security hood 100 does not damage the light bar 110. The guard 115 may be formed of steel having a thickness of at least 0.25 inches (6.35 mm). The guard 115 may also slope away from the front 101 and towards the rear side 102 of the security hood 100, as best shown in FIG. 2.

[0032] The light bar 110 may include a plurality of sections that may be illuminated independently of each other. For instance, the light bar 110 may include a first section 111, a second section 112, and a third section 113. The second section 112 is positioned linearly between the first section 111 and the third section 113. Each of the plurality of sections 111, 112, 113 may be formed of a plurality of lights, such as light-emitting diodes.

[0033] The security hood 100 may include a display 130 to broadcast written messages. The display 130 may be positioned on the front 101 of the security hood. In some embodiments, the display 130 is positioned above the light bar 110. The display 130 may be a scrolling display. The display 130 may have a height of 2 inches (50.8 mm) or less. It may be advantageous to limit the surface area of the display 130 to reduce a likelihood of contact with projectiles. For example, the display 130 may include a message “DO NOT ENTER” or another message to be communicated.

[0034] The security hood 100 may include one or more speakers 135 operable to broadcast audible warnings to the area surrounding the security barrier 10. The speakers 135 may include a horn. The speakers 135 may include prerecorded verbal messages or sounds.

[0035] The security hood 100 may include one or more cameras 136. A camera 136 is positioned on the front 101 of the security hood 100. The camera 136 may be operable to take single images or a video stream of images. The cameras 136 may be recessed within the front 101 of the security hood 100. A plurality of cameras 136 may be positioned on the security hood to provide a 360-degree field of view. In some embodiments, the cameras 136 are biometric cameras that provide information to a law enforcement agency. The biometric cameras may receive biometric information from a law enforcement agency for comparison with persons within the vicinity of the security barrier 10. The cameras 136 may have a lens diameter of less than 10 millimeters and preferably less than 6 millimeters. It may be advantageous to use cameras having a small lens diameter to reduce the likelihood of impact of projectiles on the cameras. For instance, a 9-millimeter caliber projectile would be larger than a 6-millimeter opening containing a camera lens and could only be slightly misaligned with a 10-millimeter opening to reach a camera lens within that opening.

[0036] FIG. 3 is a schematic view of the security hood 100 for the security barrier 10. The security hood 100 is operable to receive instructions from a remote command location and implement the instructions to alter operation of the security hood 100. The security hood 100 includes a light bar 110, perimeter lights 120, a display 130, and one or more speakers 135 for conveying audio and/or visual information to persons in the vicinity of the security barrier 10. The security hood 100 also includes one or more cameras 136 and/or sensors 140 for collecting data to be relayed to the remote command location. The one or more cameras 136 and/or sensors 140 may also collect data that can be used to control operation of the security hood 100. By way of example, the sensors 140 may include a microphone. The sensors 140 may include a proximity sensor to determine the distance of persons from the security barrier 10.

[0037] The security hood 100 includes memory 131, a control module 160, a communications system 170, and a power system 180. The power system 180 includes a power source such as a grid-power connection, batteries, and/or a solar panel. Batteries may be desirable to be incorporated into the security barrier 10 to minimize the effect of unreliable power or solar energy that may occur during riots.

[0038] The memory 131 includes stored settings, prerecorded written messages, and prerecorded verbal messages. The memory 131 may also be used to store new settings, written messages, and prerecorded verbal messages received from a remote command location. The control module 160 is operated to modify the functions of the light bar 110, perimeter lights 120, display 130, one or more speakers 135, and one or more cameras 136. In some embodiments, the control module 160 includes a central command module that controls operation of secondary security barriers 10 with security hoods 100 in the surrounding area. This may be advantageous to minimize the number of communication links needed to be established with the remote command location. Commands may be received from the remote command location to a security hood 100 and the central command module of the control module 160 may replicate these commands to other security hoods 100.

[0039] The communications system 170 is configured for bi-directional communication between the control module 160 and a remote command location. The communications system 170 provides data received from the remote location to the control module 160 and the control module 160 implements changes to the operation of security hood 100. The communications system 170 may also relay data collected by the security hood 100, such as camera images, to the remote location. The communications system 170 includes a communications link, such as a satellite link or a cellular connection, to permit transmissions to and/or from the security hood 100. For instance, the security hood 100 may be in communication with a central command module, another security hood 100, a governmental agency, and/or to a security agency. In some embodiments, the security hood 100 may be controlled through the use of an application on a phone or computer, such as a secure law enforcement terminal.

[0040] The security hood 100 may include one or more defense systems 150, such as nonlethal weapons. The defense systems 150 are operable to cause discomfort to unauthorized persons in the vicinity. In some applications, the defense systems may include the use of lethal force. The nonlethal weapons may include an electroshock weapon, a chemical spray, and/or a sound gun 151. As shown in FIG. 1, the security hood 100 may include a sound gun 151 extending beyond the body 109 of the security hood 100. The sound gun 151 uses acoustics to injure or incapacitate a person. The sound gun 151 includes a swivel 152 that permits the sound gun 151 to pivot up to 180 degrees but prevents the sound gun 151 from being pointed to the rear side 102 of the security hood 100.

[0041] FIG. 4 is an illustration of a plurality of security barriers 200A, 200B, 200C, 200D, 200E (collectively referred to as security barriers 200) with security hoods selectively restricting access to an area. One or more of the security barriers 200 may include a central command module for controlling operation of the other security barriers 200 (secondary security barriers) in the area. A communications link may be established between multiple security barriers 200 and a command transmission may be transmitted between the security barriers 200 to be operated collectively. In some embodiments, the security barrier 200 may be activated, or its operation altered, due to the proximity of the security barrier 200 to a command transmission. For instance, a law enforcement vehicle 230 may establish a vehicle link 231 with a security barrier 200. The vehicle link 231 may be used to carry a command transmission from the law enforcement vehicle 230 to the security barrier 200 to alter operation of the security barriers 200. In some embodiments, a satellite 210 may establish a satellite link 211 with a security barrier 200. The satellite link 211 may be used to carry a command transmission from the satellite 210 to the security barrier 200 to alter operation of the security barriers 200. A governmental agency and/or to a security agency may establish a link 221 with a security barrier 200. The link 221 may be used to carry a command transmission from an operation center, such as a security booth 220 or law enforcement agency, to the security barrier 200 to alter operation of the security barriers 200. As used herein, a remote location includes a law enforcement vehicle 230 and locations connected by a satellite link 211 or other link 221, such as a government agency.

[0042] An operator may selectively restrict access by persons 240 to an area behind the security barriers 200 by activating one or more of the security barriers 200. Initially, the security barriers 200 may be placed in an inactive state, allowing persons 240 to pass between the security barriers 200. In the inactive state, video may still be transmitted from the camera(s) 136 (shown in FIG. 1) of the security barriers 200 to a remote command location. However, in the event that the operator desires to restrict access by the persons 240, the security barriers 200 may be switched to an active state. In the active state, one or more of the audio and/or visual components may be activated to warn the persons 240 that their access is no longer authorized. This may include flashing the light bar 110 and/or perimeter lights 120 in a predetermined pattern of colors, speeds, and/or combinations; presenting written dialog on the display 130; and/or playing verbal messages or sounds through the speaker(s) 135. In some embodiments, the control module 160 may be operable to engage perimeter lights 120 before activating the speakers 135. The operator may activate defense systems 150, such as a sound gun 151, to inhibit further access into the area. In some embodiments, the defense systems 150 may activate automatically when unauthorized persons 240 come within a predetermined distance of the security barriers 200 while they are in the active state, as determined by a proximity sensor or cameras.

[0043] By way of example, a security barrier 200 having a security hood 100 (shown in FIG. 1) may instruct persons in the area to move to the right by sequentially illuminating first section 111, then second section 112, and then third section 113 of light bar 110. The sequential illumination may be continued across adjacent security barriers 200. The display 130 may display a message, such as “Turn Left”, while the light bar 110 is illuminated and/or the speakers 135 may broadcast a prerecorded message.

[0044] To inhibit access to the area, the light bar 110 and/or perimeter lights 120 may flash and the frequency of the flashing may increase as the unauthorized persons approach the security barrier 200. The light bar 110 and perimeter lights 120 may alternate illuminating. The light bar 110 and/or perimeter lights 120 may change colors as the unauthorized persons approach the security barrier 200.

[0045] Although this disclosure has been described in terms of certain embodiments, other embodiments that are apparent to those of ordinary skill in the art, including embodiments that do not provide all of the features and advantages set forth herein, are also within the scope of this disclosure. Accordingly, the scope of the present disclosure is defined only by reference to the appended claims and equivalents thereof.
