Doors

Your roller doors might be smooth, but they'll never be this smooth. Californian company Hover Doors uses permanent magnets to float heavy sliding doors as if they're mag-lev monorails, for super-quiet, minimal-effort opening and closing.

Folks entering shopping malls, airport lounges and office buildings could soon be welcomed by colorful greetings, important messages and of course adverts as they approach the sliding doors, thanks to a partnership between LG and Assa Abloy.

At CES this week Ring is aiming for renters with the new Door View Cam. This battery-powered video doorbell is designed to slot into an existing peephole, so it can be easily installed and removed later.

We've all been there: you're just drifting off to sleep and then realize you may have left the back door open. Spare a thought for the owners of the House in Morrillos, as they've got a total of 72 doors to check. Located in Chile, this beach house has some interesting ideas up its sleeve.

Ring's Video Doorbell allows users to see and speak with visitors to their home via a mobile device, no matter where they are. The company recently announced that it has raised US$28 million in Series B funding led by Sir Richard Branson, Shea Ventures and American Family Insurance.

Car doors can be ungainly when they're being opened, smacking into things like garage walls, light posts, or the body panels of other cars. That's why a group of German high school students has developed a system that stops the door from opening before it can hit anything.

There are already external door-mounted cameras that stream video of visitors to users' smartphones, plus there are cameras that fit into existing door peepholes, recording shots of visitors and displaying them on an LCD screen. Peeple, however, is kind of a combination of the two.

At some point or another, you've probably half-heartedly swung your car's passenger door closed, only to see the "door ajar" light come on once you're on the road. Slamming the doors shut is one option, although Slamstop is designed to be a quieter alternative.

A new, highly insulated, automated pet door lets pets in and out without breaching thermal standards. The electronic, programmable, personalized Petwalk caters to design- and energy-conscious pet lovers.
