Patent Images
1. A circuit, comprising:
- a microprocessor connected to a power source; and
a plurality of light-emitting diodes having a predetermined power rating, the microprocessor, when receiving power from the power source, to supply a pulse of current to the light-emitting diodes as follows;
supplying current exceeding the power rating of the light-emitting diodes for a predetermined time period; and
supplying no current to the light-emitting diodes for at least ten times the predetermined time period; and
a transistor whose gate is connected to an output of the microprocessor,wherein the transistor drives the plurality of light-emitting diodes;
wherein the plurality of light-emitting diodes do not break.

Abstract
A novel safety harness is disclosed. The safety harness has straps for securing upon a subject. Arranged around the straps are several light emitting diodes (LEDs). The LEDs are driven by pulses of current that exceed the power rating of the LED, but the current is driven for a very short period of time, such that the LEDs are not destroyed. These LEDs blink when turned on and emit substantially more light than is typically found in LEDs, such that the subject is visible from a distance of up to two thousand feet. Multiple safety harnesses may be strapped together, allowing the safety device to be used in a variety of settings, both for human and non-human subjects.
