People who bring their presentations to a meeting on a memory stick, often find themselves searching for a USB slot on a laptop.
When the lights are low in a lecture theatre, the problem is especially difficult.
Today’s invention is therefore a tiny, battery-powered LED on a memory stick, just like one of those keyrings which help you to find your car doorlock.
Pressing a button would allow the stick to be inserted with no fussing and no need to interrupt the mood of the meeting by turning up the main lights.
hmmm…
