Communicating through Bluetooth is a good idea. Then you could have an app on the phone that communicates the way you want to. If it is the local police, then that is who is called. I guess that the "issue" is the storage of the video. Perhaps there could be a clooud service for storage of the video. Of course, if you have a service that is set up the way the designer has specified, then you do that. I
I see this as useful for litigation on both sides, as long as the video doesn't conveniently "disappear".
I think there needs to be a reevaluation of how many cell-connected devices one must carry though. If this device is going to call the police for you, one likely has four or more cell-service devices at close hand - the pepper spray can, a cell phone, a tablet such as i-pad, and the on-star service in a car.
I'd rather see this device be blue-tooth connected to my phone.
Glad to hear that the image shown is not the image they were planning to bring to market. There would be no way any one would carry around a device like that--far too big and scary looking.
I suppose that there's high utility in using a pepper spray gun correctly, but I guess I'm of mindset that we don't want to make it too easy. I could see one of these things whipping out on the soccer field as two over-the-top parents from opposing teams go at it. For me, the coolest thing about this innovation is the lessons it can bring in terms of mechatronics design. That's what is most important.
Although plastics make up only about 11% of all US municipal solid waste, many are actually more energy-dense than coal. Converting these non-recycled plastics into energy with existing technologies could reduce US coal consumption, as well as boost domestic energy reserves, says a new study.
