DETAILED DESCRIPTION OF THE INVENTION
[0040] FIG. 1 shows the LIDAR monitoring system, shown generally at 10, including the enclosure 12, carried by pole 14. The enclosure carries three LIDAR devices, 16, 18 and 20, which provide a 3D map covering 180 degrees around the enclosure 12. An HD light 22 is provided in case of darkness, and an HD camera 24 is provided to supplement the 3D lidar map. An optional GPS unit can also be carried, if GPS location coordinates are desirable. A wireless communication device can also be included to allow transmission of the scan data and GPS data to the authorities. The wireless communication system can be any available system such as cellular, wifi or bluetooth.
[0041] FIG. 2 shows the cart generally at 26, the track, generally at 28, and a stator section, shown generally at 30. The cart 26, has plates 32 and 34, which fit around stator plate 36, which carry coils when energized produce a magnetic field which interact with the plates 32 and 34 which carry a permanent magnet, to either push or pull the cart, causing it to move down the track. Each stator section 30 is powered by power cables that come from a drive cabinet (not shown). As each stator section 30 is energized the electromagnetic wave form drives the cart along the track in a frictionless manner. The cart has wheels (upper wheels 38 and lower wheels 40, best shown in FIG. 3) and still rolls along the track, however; the cart is being pushed or pulled by the magnetic wave form emitting from the stator sections 30.
[0042] FIG. 3 shows the cart 26 in more detail. The cart has a platform 42 which carry two sets of wheels, front and back, the wheels having top and bottom wheels 38 and 40. The cart carries a computer 44 and a battery 46, which powers the computer and LIDAR equipment.
[0043] FIG. 4 shows the track 28, with the stator 30, carrying the cart 26, inside the enclosure 48, which has an opening through which pole 14 and LIDAR enclosure 12 extend. FIG. 5 shows a perspective view of FIG. 4.
[0044] FIG. 6 shows a picture of a section of track 28.
[0045] FIG. 7 shows a wheel assembly 37, including the top wheels 38 and the lower wheels 40.
[0046] FIG. 8 shows the cart 26 on the stator section 30, with cart plates 32 and 34, which carry permanent magnet 50, which is positioned close to stator plate 36.
[0047] FIG. 9 shows the track with three stator sections 30. As the cart 26 passes over each stator section 30, the stator section is energized to generate the magnetic field which either pushes or pulls the cart, causing it to move down the track. The cart can move in either direction and can be speed up or slowed down by controlling the magnetic field generated by the stator section 30. The track can be as long as desired, carrying as many stator sections as necessary. A drive cabinet (not shown) provides power for up to 36 stator sections, and as many drive cabinets are provided as is necessary. Each stator section 30 is energized as the cart 26 passes over it, and de-energized after the cart has passed over it to minimize the power necessary to move the cart. The drive cabinets can obtain their power from solar power, generators or direct AC hookup, depending on location.
[0048] FIG. 10 shows several applications for the LIDAR detection system. These applications show the LIDAR detection system used for foreign object detection (FOD) for a runway (52), on a Formula One track (54), on a MOTO track (56) and on a Nascar track (58). The track is positioned next to the track and a reference LIDAR scan is compared to a current scan, which allows for any foreign object (down to 2 centimeters in size) to be detected. The scan can be performed before a take-off or landing or before each race or after an accident on the track. Detecting foreign objects and facilitating their removal improves the safety of airports and race tracks.
[0049] FIG. 11 shows a runway 60 with several tracks 28 and carts 26 positioned on either side of the runway. The invention can image the entire runway from one side, but provides better detection if positioned on both sides.
[0050] FIG. 12 shows an example runway monitoring display for a runway foreign object detection (FOB) system.
[0051] FIG. 13 shows a display which shows debris detection over time, which allows for identifying critical points, such as areas where debris blows onto the runway or areas where birds cluster.
[0052] FIG. 14 shows an example of a grid alert display, which is configured to allow precise location of debris on a grid, and the size of the debris. The cart can be requested to move to the grid location and turn on a light to allow for a user to know where the debris is, for ease of removal.
[0053] FIG. 15 shows several additional applications for the LIDAR detection system. In addition to the four application shown in FIG. 10, the LIDAR detection system can be used for foreign object detection (FOD) for a runway on an aircraft carrier (62), for pipeline scanning (64), for over/under long span bridge scanning (66) and for border protection (68).
[0054] FIG. 16 shows the invention deployed on an aircraft carrier, where the track is shown at 28 and the LIDAR scanning coverage is shown at 70.
[0055] FIG. 17 shows the invention deployed on a Nascar racetrack, where the track is shown at 28 and the LIDAR scanning coverage is shown at 70.
[0056] FIG. 18 shows that multiple LIDAR detection devices 10 can be deployed. Advertising opportunities also exist with this technology.
[0057] FIGS. 19 and 20 show a track 28 deployed at a Formula One track with advertising 72 shown on top of the enclosure 12. Multiple carts 26 can be deployed if desired.
[0058] FIG. 21 shows the invention deployed for long span bridge inspection, with LIDAR devices positioned for scanning under and over the bridge, at 74 and 76.
[0059] FIG. 22 shows the invention deployed for pipeline inspection, with multiple LIDARS shown at 78, 80, 82 and 84 for scanning around the entire pipeline.
[0060] FIG. 23 shows the invention deployed along a country border to scan for border crossings. The track 28 can be elevated, 60 feet in this instance, to prevent the detection device from being tampered with. The scan data can be wirelessly transmitted to authorities along with geo location data.
