Abstract

A flashing light system uses a controller or controlling integrated circuit to flash one or more series of lamps, such as LEDs. The lamps or LEDs are arranged to form a predetermined pattern, such as a letter or other alphanumeric character. Random patterns may also be generated and used. The LEDs may also be arranged to highlight or display an illustration, a logo or other character.

6. The system of claim 5, wherein the controller is a CMOS controller.

7. The system of claim 1, further comprising a memory of the controller or a memory accessible to the controller, the memory storing data defining at least two patterns at least two patterns of alphanumeric characters, wherein the sequence displayed is responsive to a frequency of the switch closing.

8. The system of claim 7, wherein the patterns of alphanumeric characters comprise a sequential pattern, a forward pattern, a reversed pattern, a random pattern, a fade-in sequential pattern and a fade-out sequential pattern.

9. The system of claim 7, wherein the controller comprises at least two NAND circuits.

10. The system of claim 1, wherein the lamps comprise LEDs in a display, and the LEDs in the display are separated vertically by not more than 2 mm.

11. The flashing light system of claim 1, further comprising footwear into which the system is assembled.

12. The system of claim 1, wherein the power source comprises two batteries and wherein at least one of the plurality of LEDs is connected to two different voltages in the sequence.

13. The system of claim 1, further comprising a second plurality of lamps connected to the power source and the controller.

14. The system of claim 13, further comprising a memory accessible to the controller, the memory storing data defining at least two patterns for flashing the lamps.

15. The system of claim 13, further comprising a plastic display, wherein the second plurality of lamps is embedded in the plastic display.

16. The system of claim 13, wherein the power source comprises two batteries and wherein at least one of the LEDs in the first plurality and the second plurality is connected to two different voltages in sequence.

17. The system of claim 1, further comprising a battery charger.

18. The system of claim 1, further comprising a personal accessory.

19. A method of displaying a message, the method comprising:

wearing an item selected from the group consisting of footwear, an article of clothing, and a personal accessory, the item further comprising the flashing light system of claim 1;

activating the flashing light system; and

displaying the message.

20. A method of displaying a message, the method comprising:

furnishing a flashing light system in footwear, an article of clothing, or a personal accessory, the flashing light system further comprising a controller, a power source connected to the controller, a switch connected to at least one of the power source and the controller, and a plurality of lamps connected to the controller;

activating the flashing light system; and

displaying a message by quickly flashing the lamps in sequence, wherein the lamps flash at least two alphanumeric characters in a sequence to form the message.

21. The method of claim 20, wherein moving the switch is accomplished by one of touching the switch, toggling the switch, and moving the footwear or personal accessory to close an inertia switch.

22. The method of claim 20, wherein the switch is an inertia switch, and a first message is displayed when the inertia switch is closed at a low frequency, and a second message is displayed when the inertia switch is closed at a higher frequency.

23. The method of claim 20, wherein the flashing light system further comprises a second plurality of lamps, and wherein the method further comprises flashing at least one pattern with the second plurality of lamps.

24. A flashing light system, comprising:

a controller;

a power source connected to the controller;
