No. 12/303,802 filed on Aug. 12, 2008; application Ser No. 12/303,802 is a National Stage Entry of PCT/US07/70494 filed on Jun. 6, 2007, which claims priority of Provisional Application No. 60/811,157 filed on Jun. 6, 2006, the disclosures of all of which application are incorporated by reference herein in their entirety.


BACKGROUND OF THE INVENTION
1. Field of the Invention
Disclosed herein is a flashing beacon. More specifically, disclosed herein is a flashing beacon that may be positioned on most any roadway sign or signpost, and that may include a signal unit, a control unit, a solar collector, an activation device (e.g., a timer, microwave emitter, radio transmitter, step-pad, a pushbutton, infrared transmitter, wireless transmitter or like device) and various other accessories.
2. Reference to Related Art
According to the U.S. Manual on Uniform Traffic Control Devices, flasher mechanisms associated with traffic control signs (e.g., a yield or crosswalk sign) must be positioned on the sign (or signpost) so that flashing signal is about 12 feet above the pavement. The flashing signal must also be programmed or otherwise set to flash continuously at a rate of not less than 50 nor more than 60 times per minute. See MUTCD, Section 4D.11. However, while the guidelines set forth in the uniform regulations are intended to provide a visible warning to drivers, recent testing has suggested that only a small percentage of the public responds to flashing signals that operate according to the uniform regulations. Specifically, recent testing has suggest that only 25% of the public complies with or otherwise responds to flashing signals associated with roadway signage. Therefore, it would be advantageous to have an improved flashing beacon system that may be used with existing or future roadway signage to garner a greater response from the vehicle driving public.
SUMMARY OF THE INVENTION
About 20 years ago, the public began to demand that the automotive industry manufacture “quiet” cars and trucks—and the industry responded. Indeed, the industry responded so well that the interior of many vehicles have been effectively transformed into moving soundproof rooms. Unfortunately, the “quiet” has sometime resulted in drivers and passengers alike becoming distracted and forgetting that they are in a moving vehicle. For example, it is not uncommon for present day drivers to be seen talking on a cellular phone, reading a paper, listening to satellite stereo systems, being distract by children in the vehicle, applying makeup, using on-board navigation systems, watching a DVD, or just plain not paying attention to the roadway.
Clearly, one thing that is lost or diminished by all these possible distraction is a proper attention to and respect for roadway signage—signage that exists to increase motorist safety. Existing roadway signage is quite often clear and concise in meaning and message. These signs, however, lose their effectiveness when paired up against a distracted driver.
A 12′′ flashing beacon has been the tool of choice for the nation's roadways to emphasize a warning on a roadway sign since 1955. Indeed, the flashing pattern and height of these flash beacons might still work on some signs in certain locations. However, given the array of distractions now available to drivers, these traditional flashing beacons are simply too passive. Accordingly, disclosed herein is a beacon having a unique flashing sequence, and installation placement, that upon activation may command a driver's attention. As such, drivers are compelled to again look at a sign, understand its message, and respond.
As disclosed herein, a flashing beacon may include a signal unit, a control unit associated with the signal unit, a solar panel or collector, and an activation device that may all be mounted or otherwise positioned on a post of a roadway signpost. The activation device and solar panel may, however, also be positioned remotely from the post.
The signal unit may be rectangular in shape (although other shapes may be used) in order to decrease its obstructive profile relative to the sign, and it includes one or more flashable lights (e.g., LEDs) on the front, rear, bottom or side faces of the signal unit. One or more spotlights (e.g., LED spotlights) may also be positioned on the signal unit to illuminate an area (e.g., the street) in the vicinity of the signal unit. The signal unit may also include an audio transmission system and one or more displays (e.g., a LCD, plasma, or LEDs) to provide the user with information concerning the operation of the flashing beacon.
The control unit may include an electronic signal receiver (e.g., a radio receiver), a power supply, and control means for use in controlling the initiation and duration of the light assemblies of the flashing beacon.
The solar collector may include one or more solar cells that provide power to the unit during daylight hours and may also operate to recharge the power supply of the control unit so that the flashing beacon has adequate power during evening hours.
Finally, the activation device may include a pushbutton unit, signage, one or more counter displays, an infrared sensor, and a speaker system. Additional accessories for the activation device may also include devices such as a timer, microwave emitter, radio transmitter, step-pad, a pushbutton, infrared transmitter, wireless transmitter or like device. The signage associated with the pushbutton may also include a display (e.g., a LCD, plasma, or LEDs) to convey additional instructions to a pedestrian concerning operation of the flashing beacon and a counter to record the number of times the beacon has been activated. Finally, it will be appreciated that while the flashing beacon disclosed herein is discussed as being used in connection with a pedestrian crosswalk sign, it may also be used with any sign, placard or signal that uses a flashing signal (e.g., fire station sign, yield signs, dangerous curve signs, school speed zone signs, etc.).

DESCRIPTION OF THE INVENTION
Referring now to FIGS. 1-10, a flashing beacon 10 for a sign(s) 5 may include a signal unit 12, a control unit 14, a solar collector 16, and an activation device 18 that may all be removably mounted to a post 7 of a sign 5. In operation, the flashing beacon 10 may provide a safer environment for drivers and pedestrians, particularly pedestrians attempting to traverse a busy street.
Referring now to FIGS. 1-5, 8 and 9, the signal unit 12 may have an elongated, rectangular shaped body that may include a front face 20, a rear face 22, a pair of side faces 24, 25 and bottom face 26. A recess 28 may be defined in the front face 28 of the signal unit 12 such that the signal unit 12 may be positioned along the post 7 of the roadway sign 5. One or more light units 30 may be positioned on, or alternatively recessed within (see e.g., FIG. 8), each of the front face 20, the rear face 22, the side faces 24, 25 and the bottom face 26 of the signal unit 12. As shown in FIGS. 8 and 9, one or more illuminated street signs 27 may also be associated with each flashing beacon 10 and mounted by mounting each sign on the post of the sign 5. Further, as shown in FIG. 1, the signal unit 12 may be positioned on the sign post 7 immediately below the sign 5 so that, in a typically configuration, the light units 30 of the signal unit 12 are approximately the same distance above ground level as a traditional police cruiser. It is appreciated that a lighting array at such a height may receive greater recognition from a vehicle operator who might otherwise be “trained” to slow his or her vehicle when encountering flashing lights at this height.
Referring to FIGS. 1-5, 8-11, and as best shown in FIG. 1, during operation of the flashing beacon 10 the light units 30 of the front face 20 of the signal unit 12 may be illuminated to alert oncoming vehicle traffic that a pedestrian(s) 8 has or is about to enter a crosswalk. Light units 30 on the rear face 22 may also be illuminated concurrently with the light units 30 of the front face 20 to alert vehicle traffic traveling in the opposing direction. Accordingly, it will be appreciated that where at least one flashing beacon 10 is positioned on each side of a roadway (or, e.g., on at least one side and in a center median), a vehicle will be alerted to the presence of a pedestrian(s) in an approaching crosswalk regardless of the vehicle's direction of travel. Further, as shown in FIGS. 8 and 11, the light units 30 on the rear face 22 of the signal unit 12 may be pivotably mounted to the signal unit 12 so that (during setup) each light unit 30 may be precisely aimed at oncoming traffic.
Still referring to FIGS. 1-5, 8 and 9, in addition to the light units 30 associated with the front 20 and rear 22 face of the signal unit 12, the light units 30 of each side face 24, 25 of the signal unit 12 may be illuminated to alert the pedestrian(s) 8 and/or crossing guard(s) 9 using the flashing beacon 10 that the light units 30 on the front 20 and rear 22 face of the signal unit 12 been activated. As such, by observing the illumination of a light unit 30 on a side face 24, 25 of a signal unit 12, a pedestrian 8 or crossing guard 9 on one side of a roadway may easily confirm that the light units 30 on front 20 and rear 22 faces on a signal unit 12 on the opposite side of the roadway have also been activated.
Still referring to FIGS. 1-5, 8 and 9, in addition to the light units 30 on the front 20, rear 22, and side 24, 25 faces of a signal unit 12, each signal unit 12 may also include lighting for illuminating the area proximate base of the post 7, including at least a portion of a nearby roadway. For example, one or more light units 30 may be positioned on the bottom face 26 of the signal unit 12. Further, as shown in FIGS. 1-5, the signal unit 12 may also one or more spotlights 32 (e.g., LED spotlights) that extend from the signal unit 12. As shown in FIGS. 8 and 9, the spotlights 32 may be constructed as lighting pods 33 that are mounted to the bottom face 26 of the signal unit 12. Each lighting pod 33 may include one or more LED lights. The lighting pods 33 may also be mounted to a signal unit 12 so that any light emitting from the pod 33 is projected directly downward or at a predetermined angle relative to the post 7. Further, as shown in FIGS. 8 and 9, one or more spotlights 35 may be used to illuminate the face of a sign 5. Specifically, the spotlights 35 may be positioned on stanchions 39 that extend from the post 7.
Referring again to FIGS. 1-5, 8 and 9, as mentioned above the light units 30, spotlights 32 and other light units of the flashing beacon 10 may each include one or more light emitting diodes (“LEDs”). For example, LEDs of the type manufactured by Whelan Engineering Inc. may be used in connection with the light units 30 and spotlights 32 of flashing beacon 10. However, it will be appreciated that other types of lights may also be used with the flashing beacon 10.
The one or more of the lights of the light units 30 (i.e., the light units 30 on the bottom face 26) may function to be continuously illuminated during operation of the flashing beacon 10. However, as mentioned above, the light units 30 of the flashing beacon 10 may also function to flash according to uniform regulations at a rate of 50-60 cycles per minute, at an increased rate of 60-110 cycles per minute, or at any other rate predetermined by the user. The light units 30 may further be arranged such that they flash in a predetermined pattern such as a wavy line or a so-called wig-wag flashing pattern as will be described below.
Referring now to FIG. 5, the signal unit 12 may also include a programmable audio unit and a voltage meter display 36. The voltage meter display 36 (which may also be positioned in the control unit 14) may include an LCD, plasma screen monitor or an arrangement of LEDs positioned on the bottom face 26 of the signal unit 12 that may be in electrical communication with a power supply (i.e., a battery—not shown) of the control unit 14 (as discussed below) or another battery (not shown) that may be positioned in the signal unit 12. An audio unit (which may also be incorporated into the activation device 18) may include audio transmission apparatus that includes at least one speaker 38 and a memory means (e.g., an erasable/programmable memory). The memory means (not shown) may permit an administrator of the flashing beacon 10 to program and/or change an audio message that is broadcast to a user of the beacon 10.
Referring again to FIGS. 1-5, 8 and 9, the control unit 14 of the flashing beacon 10 may include one or more electronic signal receivers (i.e., a radio or wireless receiver) including an antennae 42, 43, a power supply (i.e., a battery), and control means (i.e., an erasable programmable memory (not shown)) for use in controlling activation of the light units 30 and spotlights 32 of the signal unit 12.
In operation, the control unit 14 may be used to selectively activate and deactivate the various lights of the flashing beacon 10. For example, a school principal, crossing guard 9 (see FIG. 1), or public safety official may use a remote transmitter to activate, program or otherwise control the activation of the flashing beacon 10 by transmitting an appropriate signal to the signal receiver of the control unit 14. More specifically, as shown in FIG. 1, the crossing guard 9 may carry with him or her a personal flash beacon system 45 such as the Personal DefenderTM or Crosswalk DefenderTM manufactured by Stop Experts, Inc. of Venice, Fla. These personal flash beacon systems may include a radio transmitter that when activated results in the activation of the lights of the flashing beacon 10 and when deactivated results in the deactivation of the lights of the flashing beacon.
Referring now to FIGS. 1-4, the solar collector 16 may include a panel of one or more solar cells 48. The panel 16 may be positioned on arm 50 that extends above the sign from the control unit 16, or that is otherwise mounted to the post 7 of the sign 5. Further, as shown in FIG. 1, in those instances where the overhead tree cover may prevent sufficient exposure of the solar collector to direct sunlight, the solar collector 16 may be positioned a predetermined distance away from the flashing beacon 10 and electrically connected to the beacon 10 by means of underground electrical wire and conduit. It will be appreciated that the solar collector 16 may be used as a clean power source for the signal unit 12 and the control 14 of the flashing beacon 10 during daylight hours. It may also be appreciated that the solar collector 16 may communicate with the power supply of the control unit 14 to thereby provide power to the flashing beacon 14 during evening hours.
Referring now to FIGS. 1-4, 6 and 7, the activation device 18 may include a pushbutton 52 in electrical, wireless or radio communication with the control unit and/or the signal unit, and one or more placards 54 that may convey additional information concerning operation of the flashing beacon 10. Pushing the pushbutton 52 may activate that flashing beacon 10. However, it should also be appreciated that other devices such as a timer, microwave emitter, radio transmitter, step-pad, internal activation means, a timer, a pushbutton, infrared transmitter, wireless transmitter or like device. For example, the activation device may include an infrared sensor 57 that may detect the presence of an individual within a predetermined range (e.g., 5 feet) from the device 18 and respond by activation of the flashing beacon 10.
Still referring to FIGS. 1-4, 6 and 7, one or more displays 55 (e.g., LCD, plasma screen monitor, or LEDs) may also be positioned on the activation device 18 to provide a user with an additional instructional message. For example, as shown in FIG. 7, the activation device may include a pair of displays 55 that indicate the number of time the flashing beacon has been activated during daylight hours (right side) and after dark (left side). Likewise, as mentioned above, the activation device 18 may include memory means and an associated speaker system capable for providing a user with an audible instructional message.
Referring now to FIGS. 1-3, the flashing beacon 10 may also include a double-sign unit 56. As shown in FIG. 2, the double-sign unit 56 may include a first sign placard 58 and a second sign placard 60 that is movable relative to the first sign placard 58. Prior to activation of the flashing beacon 10, the second sign placard 60 may be positioned in front of the first sign placard 58. However, upon activation of the flashing beacon 10, the second sign placard 60 may be translated or otherwise shifted to a second position to thereby reveal the first sign placard 58. Further, the first sign placard may include one or more LEDs 62 to thereby illuminate the first sign placard.
Referring now to FIG. 9, a light bar 64 that may include one or more light units 30 may be positioned on the signpost 7 below the signal unit 12. Alternatively, the light bar 64 may be positioned above the signal unit 12 or between the light unit 30 on the front face 20 of the signal unit 12. In operation, the light bar 64 functions to quickly “flash” any oncoming vehicles. Typically, this flash may about 11⁄2 to 2 seconds after any lights on the front 20, rear 22, or side 24, 25 faces of the signal unit 12 had been activated. The advantage of this “flash” (in addition to the normal illumination of the flashing beacon) is that a vehicle that is already within a predetermined distance from the flashing beacon 10 may not see the flash because, in many instances, the vehicle will have already driven past the beacon 10 given the 2 second delay period. However, vehicles that were beyond the predetermined distance when the flashing beacon 12 was activated will encounter not only the normal illumination of the flashing beacon, but also the secondary “flash” of the light bar 64. As such, the secondary flash functions as a further reminder to the driver to heed the commands of the associated sign 5.
In preliminary testing of the flashing beacon disclosed herein, Applicant has achieved significant improvement over the traditional flash beacon systems known in the art.
EXAMPLE 1
A study of percent of vehicle responses to 70 pedestrian crossings comparing a traditional (MUTCD Standard) flashing beacon with dual side mounted lights (top row) against Applicant's flashing beacon with dual flashing overhead lights with a “wig-wag” flashing pattern (bottom row) in the City of St. Petersburg, Fla. at 31st Street north of 54th Avenue South. A wig-wag pattern is described as follows: Where the front face 20 of the signal unit 12 of the flashing beacon 10 being tested included two side-by-side LED lights, each wig-wag cycle including two flashes (adjustable) of one light and, simultaneously, three flashes (adjustable) of the other light. The speed of the left and right flashes is adjusted so that the cycle time for the three flashes for the other light is equal to the cycle time for the two flashes. Each flash beacon tested was set up to function at a rate of 76 wig-wag cycles per 30 seconds (for a total of 190 total flashes).
