Protective mechanism of dropped iphones

Some laptops have it to protect their hard drives. Detection mechanism is interesting but shifting mass could be tricky. And does provide some "innovation"

Re: Protective mechanism of dropped iphones

Couldn't that be accomplished with a couple gyros? If they could manage to stick two gyros in the phone at perpendicular planes, the phone will likely be rotating on some axis that could ever so slightly be affected by one of the gyros spinning. Now add a sensor that knows the direction of the fall and it seems plausible that ABS-like on and off signals to the two gyros could manage to create a "cat-like" landing on whatever portion of the phone can best withstand shock. If you lay the phone flat, I could see them fitting a horizontal plane gyro but I have no idea how one in the vertical plane could be added. It just isn't thick enough. Perhaps one gyro is enough and by turning it on and off in opposite directions they can arrest the tumble and orient it to best withstand the shock.

I know one thing -- this would be an interesting project for science students to do in a lab with something like the Rasberry Pi, a gyro and a motion detector. I don't know if the Pi comes with WiFi but if it did, it would be neat to make it more of a drone, sending sensor signals to a nearby laptop/desktop that then contains software to tell the gyro what to do. That would improve productivity since once the Pi is running a program to send and receive signals over WiFi, a socket server could be running on the laptop/desktop with a full IDE where the software can rapidly be tweaked and deployed for the next drop test.

I suppose some kind of solenoid weight shift might also be a plausible solution if the gyros cannot be small enough to still have an effect.

I started with gyros thinking the vibrator in the phone could possibly double as a gyro?

Re: Protective mechanism of dropped iphones

It's an interesting idea, but I suspect the best solution is to have a design which absorbs shock well to prevent damage.

OS X trojan, lots of user intervention required to install

You have to really want that thing given you have to first turn off the Gatekeeper and then fire up an installer and provide your password.

Re: OS X trojan, lots of user intervention required to install

You've met the average OSX user? I have seen plenty, and lets just say that the majority largely carry the stereotype of a mac user perfectly..

It becomes kinda bad when I can show most of these people more things then they ever knew existed in OSX in 5 minutes.

Re: OS X trojan, lots of user intervention required to install

Yeah I worked in technical support for Mac software. I would say like 75% of the time I was asked how to do something inlcuding installing or uninstalling a software or telling them to go to finder and they would ask where it is.
The funny thing is they would usually be put on hold for at least 5-10 minutes to get to mac support then comment on it when I answered about having to hold because they have a mac but love it because it is so easy to use. Then I tell them to uninstall the version they have and they ask me how. Or they would enter their wifi password instead of their mac password because most the time they referred to it as their internet password.

I'm sure if they had a windows computer then they would have been the type to have 3-5 extra browser tool bars and tons of trojans.

With that, they wouldn't be able to get gatekeeper turned off to get the trojan installed.
