6th-graders invent an automatic IV drop counter with an OLED, seek patent

This is an interesting story: a group of 6th-graders from Tucson, Arizona have developed an automated IV drop counter. This $1.5 device can help medical personal avoid errors (under-dosing or overdosing) - and is much cheaper than an infusion pump which costs $5000.

The kids used an OLED display on their device, and have requested a patent on the design.
