It looks like it is using a combination of sensors which are now cheap and in most cell phones. They are using an accelerometer, a lean angle sensor, and probably a magnetometer. They defeat the holding action of the switch with foam inserts to convert the switch into a momentary one. I so rarely forget to cancel a turn signal, nor find it a hassle, it doesn't interest me, but it is a cool mod for someone that does.
For the eight years I have been riding my '08 C14 I have used a Kriss turn signal cancellation unit. It's cost is $129 but not really worth it as it only does a half-assed job. After either signal blinks 15 time, the signal ceases. If while it is blinking you activate the brakes the signal will continue to blink and reset itself to 15 blinks before cancellation. The trouble is the signal is merely cancelled by the unit while the turn signal switch remains in either left or right position. After every turn signal use you must manually reset the switch. Not much of a product but it has had no competition until recently.

The new kid on the block is a real winner. It's an electronic unit that is the result of efforts expended by four Slovenian motorcycle enthusiasts with a knowledge of modern electronics. They have created a wonderful product that actually turns the signals off after completion of a turn and even a lane change on the freeway. No counting blinks. This unit has sensors that somehow know when to turn the blinkers off, left or right turns and freeway lane changes. It is perfect and far surpasses any motorcycle turn signal cancellation unit, stock or aftermarket. I suggest you peruse the following link to read about it and to see a video. The price is €149.00 or $168 at the current exchange rate. I rate it equal to the claims by both the manufacturer and by users of the product. All of which are accurate but can be seen as raves. The item is deserving of raves. I endorse it wholeheartedly and consider it well worth the money.

I took a quick look at the website but frankly, could not cut through 'slick interface' to get to any facts. ??
So I will ask you.
Do they replace parts in the turn signal switch so that it returns to neutral automatically?

I already have factory fitted self cancelling indicators.
They're called "hand signals" and they cancel when I put my hand back on the grips
Looks like this STS system uses an IMU (inertial measurement unit) with some algorithms to detect the maneuver. More and more bikes are getting IMU's for things like cornering ABS, traction control and cornering lighting. My Ducati MS has an IMU and the new FJR does as well. This seems like it would be a low cost add to any bike that already has one. Just software. And the MEMS chips needed for an IMU are dirt cheap now. Literally pennies. What a great idea.
Yes, simple enough to do once the hardware is corrected; the turn signal switch needs to be a momentary contact but after that, it is all sensors and code. Three axis accelerators are cheap and very effective, and MCU's are all over the place for, as you mentioned, pennies. The code starts off looking like it will be pricey but as always it becomes cheap if it can be spread out across a lot of units, and a turn signal system is something that would work on any motorcycle, regardless of model, brand or anything else.
And using accelerometers it becomes easy to get a handle on all parameters of the bikes' behavior such as sitting at a light: no accel / decel, no speed and the turn signal can stay on for as long as needed, waiting for the rotation (the turn) combined with acceleration. It becomes very easy to map exactly what behavior to look for and when to cancel the signal.
As a no- cost extra, a sudden, near- ninety degree rotation about the yaw axis followed by a sharp decel to [no speed] and this controller could snap on all four signal lights as an emergency flasher.... 'cause the bike just fell over. Sort of the thinking man's tip over sensor..... well, not really a thinking man perhaps, maybe more like the almost- sober man.

Hey! That's possible! Didn't Einstein or someone else VERY smart theorize about gravitational waves?
If that Indian falls down, the gravity waves will ripple throughout the known universe.
