Did you leave the light on?1 Jul 2021 16:31
How often have you been asked to go back and turn off the light because you were wasting electricity? When you were growing up, electricity was “free” and there was a power station supplying the power so what was the problem? But, if you left your torch on then you knew that you would need to buy new batteries and you would be without your torch until then – that hurt a bit, so you always turned your torch off.
Fast forward to today, the range of your car is limited by the charge in your battery but that is not the only constraint in automotive. Components need to last a very long time in automotive, especially in safety systems, there are temperature issues and constraints in cooling, so reducing the time that a component is used and the keeping its power consumption down is crucial. So turning down the brightness and turning off a little LED that illuminates your face so that the DMS camera can see your eyes is a tiny thing, but also a massive thing. If the life is compromised they need to add more LEDs, if the cooling is compromised, they need to add more space around the component, more space in a constrained ****pit constrains design never a good idea in a class A surface that is literally in the face of the driver at all times!
There is one other place where power consumption (and heat) is even more relevant – mobile devices, this patent is also applicable to eye and face tracking on a mobile phone, tablet (or any other screen).

Just to show how important this is, the original Australian patent was applied for in 2013. The European patent application was submitted in 2014 – it was only granted a few months ago.
Now that the patent is granted, does that open the door for licensing Seeing Machines in mobile devices?
Are any of our competitor’s now liable for some license fees for infringement? Or is this just one of the many moats that is protecting our position?
Incidentally, I used to worry about abandoned patents, but now I am more pragmatic. The original Aussie application is only used to show Priority in later patent applications in the major regions. Once an application is granted in one of the major regions, there is less need to progress in every region as automotive is global, there are costs to develop and time to bring to market. A potential infringer may see that the patent is not valid in one or more regions, but knows that they are limiting themselves geographically. If you try to infringe on more than one patent, often with different geographical footprints your wriggle room is tiny - yes you could sell your car in Australia and Africa, but not in any major market.
