Fire alarming making noise because of burning toast could be really annoying at least when you want to finish quick breakfast before starting to work.

Low Technology Smoke Alarm Silencers

We used to have frequent problems with false alarms associated with burning toast in our house. Until the toaster protocol was perfected, the false alarm solution was simple. To silence the alarm we had a three foot "shut-up stick" stored in the corner below the fire alarm. Whenever the toaster triggered the alarm, the nearest person would grab the stick and reset the alarm.

Unintended consequences of gesture user interfaces

This experience clearly indicates the issues associated with devices that respond to user gestures.  If I visit your house, how will I ever know what gestures may be misinterpreted? When we travel abroad, we get hints about inappropriate gestures in other cultures ... but I never expected to have to deal with the "culture" of the internet of things in such a manner.

Even once they solve the problem -by the time they add the hardware to recognize the gesture, the MTBF of that system will ALWAYS be inferior (reliability wise) to a system that is only as complex as it needs to be to meet its functional requirements.

MWagner: Why ? because there are some people who pay for solving these kinds of problems. And what's the alternative ? working on hard problems - which is harder and more risky.

There are many examples in home automation business a.k.a Internet of Things that belong to this category of products that attempt to solve the problems that don't exist...we should have a contest which idea is the most useless...I vote for an app that checks how many times your fridge was open in the last 24 hours...Kris

Could someone explain to me why we are in such a rush to remove switches from designs?  This smoke alarm is a classic example of someone trying to solve a problem that doesn't exist.  Your alarm goes off - open a window and fan the unit for about 10 seconds --- whallla! (or get on a chair and push the button).  Is that so hard?

So, an advanced feature on a product that costs at least an order of magnitude more than its competitors from a company overvalued by several orders of magnitude doesn't work properly. Anyone want to buy one of my tulip bulbs?

Clearly you don't use your oven for broiling.

I have a saying - "If your smoke alarm ain't goin' off, you ain't really cookin'."

I respect their decision to disclose this matter. I can see they have healthy compliance inside.

michigan0 Sang Kim First, 28nm bulk is in volume manufacturing for several years by the major semiconductor companies but not 28nm FDSOI today yet. Why not? Simply because unlike 28nm bulk the LDD(Lightly Doped Drain) to minimize hot carrier generation can't be implemented in 28nm FDSOI. Furthermore, hot carrier reliability becomes worse with scaling, That is the major reason why 28nm FDSOI is not manufacturable today and will not be. Second, how can you suppress the leakage currents from such ultra short 7nm due to the short channel effects? How thin SOI thickness is required to prevent punch-through of un-dopped 7nm FDSOI? Possibly less than 4nm. Depositing such an ultra thin film less then 4nm filum uniformly and reliably over 12" wafers at the manufacturing line is extremely difficult or not even manufacturable. If not manufacturable, the 7nm FDSOI debate is over!Third, what happens when hot carriers are generated near the drain at normal operation of 7nm FDSOI? Electrons go to the positively biased drain with no harm but where the holes to go? The holes can't go to the substrate because of the thin BOX layer. Some holes may become trapped at the BOX layer causing Vt shift. However, the vast majority of holes drift through the the un-dopped SOI channel toward the N+Source,...
