Technical details about what we're doing:
We're working on a time-series problem called a Sequence Classification. Recurrent Neural Networks called Long Short-Term Memory (LSTM) networks are good for that. It’s what they use for natural language processing because it can remember context from the sentence you’ve just spoken. In this case its used to analyze not just the current timestamp of data, but what has been happening for the last 20 - 250 ms, which helps to reject false alarms.

This is a neat idea! If I may ask, what does the hardware look like on the inside of the saw? Does it somehow transmit the data from the sensors or does it run the algorithm locally? Does this massively increase the price of the saw? Finally, how would you prevent it from learning about jostling during shipping? Does it just wait for power to start, and then stay on for some amount of time after the trigger is let go? Sorry, it's a lot of questions. But again this is a really neat example of how ML can be applied to devices we've had for decades. Cool stuff!

It seemed that the built-in saw brake had a significant delay before the blade actually came to a stop. Those blades can be very dangerous even if not spinning at full speed. I'd be interested to know from your HS data whether the brake is capable of stopping the blade before it reaches flesh. It looked like at 80-100 ms, the blade is already in a position to do some damage if you had and ill-placed finger in the blade path. (And yes, I know folks, you should not have your hand there in the first place, but guess what, people do it anyway, and they pay the rest of their lives for it). This is an interesting approach that is quite different from SawStop. You are attempting to prevent the dangerous contact in the first place as opposed to minimizing the damage once contact does occur. There are also many comments on here about the spring-loaded blade guard. I'd like to see in your video how quickly a guard would respond under a kickback scenario. My guess is it probably won't be able to retract in time, as this is a very quick, chaotic event. Good research though!

I want this on chainsaws. Out of all the cutting tools I have used the chainsaw is the scariest to use even tho there is already a chain brake on it. I think applying it to the chainsaw might be more challenging as it can be used on so many different angles. Will this make a difference to the gyro meter sensor and when it activates the brake?

Evenly support the board with with 2x4s running opposite of the cut. Hold on tight and dont stand directly behind the blade. Helps to have both hands on the saw and a sharp flexible blade.

In a few years this will be on ALL saws and more, probably OSHA mandated at some point. So cheap and small its amazing. They are going to be rich beyond imagination with this patent. I'm getting my brother one as soon as they come out. He still uses the saw that nearly cut two of his fingers off.

ok, so i used to work these in europe, and the saw itself is turning the other way around basically...i don't know who would be stupid enough to use one of those..indeed very dangerous.. just make the blade go the other way and its already 50% safer no ? i'm almost a 100% positive it's the first time i see a saw like that spin towards the user..haha incredible.

Perhaps this has already been mentioned, I admit to not having read ALL the previous comments but while this is a great additional safety feature (that is completely transparent to the user in normal use - bonus!) my personal rule as an occasional user is to never let the saw out of the cut until the blade has stopped. My would-be kickback events simply become smoky black areas of the cut as the bound up blade bogs out the saw.

Every circular saw I ever bought has a guard on it that keeps the blade from cutting you. If you remove the guard your asking for a trip to the emergency room. This invention is reinventing the wheel. Sounds like you took a $39.95 saw and made it a $59.95. Reminds me of the paperless office.

I like the idea of this but I don't have high hopes of it being adopted into major tool brands. Circular and worm-drive saws have several systems already in place for this issue, plus safely operating the saw calls for always using two hands on the saw, never having anything behind the saw, and always support your work piece. It's even required by law in the US that all saws not only have guards in place but that "any saw ever made" will always have replacement guards available from part manufacturers. Even 25+ year old chop saws you can still get brand new guards for.

I'm a carpenter, kickback is user error. Little innovations like this are neat, but every time you experience kick back it is your own fault. Personally I much prefer left sided blades that are battery operated with electric brakes over the old side winders. Your blade should never pinch when cutting plywood, the smaller piece always needs to fall away from you to avoid it.

What about the fact, that circular saws, come with a guards. Which is a solution for the problem already and way cheaper to produce. Would love to see comparisons of guards vs your brake. A real test to see if the brake is worth the extra money in development, production as well as at the store for the consumer. Love what you do keep up the good work.

When a kickback lodged the blade in my finger, the saw came at me faster than the guard spring could do its job... lucky the finger bone got between the wide saw teeth and jammed the motor... and only then did I realise I was still holding on to the switch. 5 stitches later and all was good. I was really lucky!

porter cable made a circular saw many years ago(i have one) called a "Speedtronic''....it used a microprocessor that regulated the speed of the blade relative to it's resistance in the cut.....it would speed up or slow down as was necessary and you never had ''kickback'' but it was not popular with most carpenters and they wisely put a switch so they could bypass the microprocessor.....most liked the higher revving unregulated speed that they were familiar with.....i found it to be the best saw i ever used and use but alas it was and is heavy...but....it will out cut most of the modern cordless saws still...lotsa torque

You first demonstrated with a saw that is missing its blade guard, something most saws these day come with, you then showed a modified saw WITH a bladeguard. why didnt you show kickback behavior with a saw that has the bladeguard installed? is it also not quick enough? i understand that aditional safety is nice, and i imagine the sensor is small enough and cheap that the added safety feature would not impact the final costs of a saw with this feature, still, would like to know how the original feature performs to kickback.

I’m a little late to this video but guys this is friggin awesome. There are obviously some safety features already implicated in these saws main on being the spring assisted blade guard, but they don’t always save fingers because if they did we wouldn’t here or see people missing a digit or so from any mishaps pertaining to the use of the tool. I myself have luckily stayed safe enough not to have this happen but witnessed my uncle ripping a sheet of plywood and the saw kicked back severing his thumb. Now he can hitch around corners due to it being sewn back on crooked lol. I know it’s awful and I wouldn’t be laughing if it were me. Truthfully I couldn’t laugh about it for quite a while due to witnessing the event first hand. It was awful but I’m happy to say his thumb was saved and he is still very much in the business today as this had happened some years ago now. I’m rambling now so I’ll stop. I just mean to say that this is incredible and if the technology were in the saw that day he wouldn’t be wearing that scar and he’d have to hail a cab like everyone else. Awesome work guys I really hope to see this tech implicated in future circular saws as well as many other tools. Thanks for sharing.
