DETAILED DESCRIPTION

[0022] Unless otherwise stated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs.

[0023] The present invention is intended to provide a means of quickly and effectively gaining temporary control of traffic in an emergency situation and to allow a user to manipulate the flow of approaching traffic from a nearby safe location. FIGS. 3-8 depict a single portable signal unit utilized to give instruction to approaching motorists. The invention is a system comprising a remote control unit and one or more portable signal units. Each portable signal unit is to be positioned at the roadside of approaching traffic using a variety of mounting surfaces utilizing the incorporated carry handle mounting bracket 5.

[0024] Upon being deployed, the portable signal unit has, a first static message panel 1, a second static message panel 2, and an advance warning signal 3 intended to face the direction of approaching traffic. Each of the aforementioned portable signal units comprise a backlight of recessed LED arrays 19B, 19C, and 19A such that the first LED array 19B illuminates a plurality of LEDs corresponding to the first static message panel, a second LED array 19C illuminates a plurality of LEDs corresponding to the second static message panel, and a third LED array 19A illuminates the flashing advance warning signal 3. A light diffusing panel 7 is layered behind the static message panels in front of the LED arrays 19B, 19C, and 19A such that the illumination from the LED arrays 19B, 19C, and 19A enables optimized visibility of the static message panels to approaching motorists.

[0025] Internally, the portable signal unit further comprises battery groups 26, a battery charging and monitoring circuit 20, an LED driver circuit 27, a signal control circuit 28, a transceiver 29, and an antenna 21. Upon activation, the signal control circuit 28 illuminates a predetermined segment of the static message panels and advance warning signal 3 simultaneously by the LED driver circuit 27 based on default programming. Upon deploying the signal units, a user utilizes the remote control unit, depicted in FIGS. 1-2, to operate the system. The remote control unit therein comprises an internal battery 11 and an internal transceiver control circuit 10, further comprising a series of activation switches 12, a series of activation-indicating LED lights 12A, a master deactivation switch 14, and a power switch 13.

[0026] The series of activation switches 12 correspond to each of the portable signal units facing in the direction of approaching traffic such that each switch activates a predetermined segment of the static message panels corresponding to a traffic instruction. Upon activating a signal unit, the internal transceiver control circuit 10 transmits an activation signal detected by the antenna 21 and transceiver 29 inside the pre-selected portable signal unit. In a preferred embodiment, upon receipt of an activation signal, the signal control circuit 27 illuminates the backlight of the first static message panel 1, and darkens the backlight of the second static message panel 2. This action allows a user to remotely alter the instruction provided to an approaching motorist at a selected portable signal unit. Upon successful signal activation, the signal control circuit 27 transmits serial confirmation data via the transceiver 29 to be received by the remote control unit's internal transceiver control circuit 10, which illuminates the respective activation-indicating LED light 12A. Upon deactivation of the selected signal unit, the internal transceiver control circuit 10 will cease signal transmission, thereby causing the signal control circuit 27 to return to the default predetermined setting.

[0027] The master deactivation switch 14 allows the remote control unit's internal transceiver control circuit 10 to transmit a predetermined wireless transmission to the portable signal unit's transceiver 29 that deactivates the LED driver circuit 27 in order to deactivate all portable signal units and their internal LED arrays until the master deactivation switch 14 is deactivated.

[0028] The battery charging and monitoring circuit 20 incorporated into the portable signal unit enables safe charging of the internal battery groups 26 and provides consistent monitoring of pertinent electrical data. If an electrical fault or electronics failure is detected in a portable signal unit, the signal control circuit 27 transmits data via the transceiver 29 to be received by the remote control unit's internal transceiver control circuit 10, which then activates a preprogrammed alert pattern on the associated indicating LED light 12A.

[0029] In an event wherein a user attempts to activate multiple activation switches 12 at one time, the remote control unit's internal transceiver control circuit 10 will restrict transmission of the signal until all portable signal units are no longer activated.

[0030] Upon cessation of use, the portable signal unit can be collapsed to a closed position as depicted in FIGS. 6-7. The outer components of the portable signal unit comprise a hinge mechanism 4, a series of latches 6, and a rigid outer case 8. The portable signal unit can be collapsed to a closed position by utilizing the hinge mechanism 4 such that both static message panels are brought together in a folding motion depicted in FIG. 8. The series of latches 6 then fix the panels in this position. The rigid outer case 8 used to support the sign while in a deployed position becomes a means of protection during transport in this closed position.
