Abstract
Abstract An electronic circuit comprised of several integrated circuits sequentially actuates a plurality of light-emitting diodes (LED's) located in an article such as eyeglass frames, which are carried or worn by a person. In one embodiment, an oscillator driven binary up-down counter drives first and second binary to one-of-four decoders. The LED's are arranged in an electrical circuit which allows them to be addressed in X-Y matrix fashion. The first decoder sequentially addresses each "row" of LED's while the second decoder sequentially addresses each "column" of LED's in the matrix so that each LED in the matrix circuit is sequentially flashed. After the entire array of LED's has been sequentially actuated a predetermined number of times, the up-down counter is electronically switched to the opposite state so as to reverse the order in which the LED's are sequentially actuated. In a second embodiment, an integrated circuit binary ripple counter/oscillator drives first and second demultiplexers. The first demultiplexer sequentially actuates the rows of LED's in an X-Y matrix LED circuit, while the second demultiplexer sequentially actuates the columns in the matrix. The demultiplexers may be driven by the ripple counter/oscillator in a manner which allows a less than 100 percent duty cycle, thereby minimizing the drain on the battery power supply. The integrated circuits used are preferably of the complementary metal oxide semiconductor (CMOS) type for minimizing battery drain. When the invention is incorporated in eyeglass frames, the LED circuit is automatically switched on when the temple pieces of the frames are unfolded for wearing, and automatically switched off when the temple pieces are folded for storage.
