HP's scanner captures 3D objects without complicated lighting setups. Users place an object on the bed and extend a camera-equipped arm above it. The eight-megapixel camera snaps six shots (three exposures with and without flash), which an internal processor merges together to produce a single perfectly lit still.

Callers don't need to re-pair the Luna Bluetooth headset. The earpiece has a near-field communication chip to quickly link with a cellphone. When someone pops the Luna out of its base, the headset sends a signal to the phone telling it to turn on Bluetooth and put the call through.

The Bottle Lock frees bikers from bulky U-locks and clanking chains. The 1.5 metre plastic-coated steel cable coils inside a bottle that rests in a standard frame-mounted cage. It reels out of the bottle, wraps around the bike frame, and locks back into itself.

Watching 3D TV is terribly awkward for eyeglass wearers, who need to stack on two sets of specs to get the 3D effect. LG’s 1.1-ounce pair of clip-on lenses works with any of the company’s passive 3D displays. The lenses’ circular polarisation also matches up with most movie theatre 3D.

The AppBlaster gun adds a precision grip to iPhones. Snap the phone to the barrel, and download one of seven compatible apps. Games superimpose targets and enemies - ducks, troops, aliens - over a live camera image of the room around you. Pulling the trigger taps two conductive pads on the screen to fire.

At just over three kilograms, the MegaPlex is a complete pop-up theatre. Its three LCD-based projector bulbs pump out 2,800 lumens, which is enough light to display video from a laptop, game system or even a smartphone as a 250 centimetre image. Two 10-watt speakers handle the audio.

Both rugged and portable, Yamaha's single-speaker iPod dock doesn’t skimp on bass. Behind its protective steel grill, a 10 centimetre woofer pumps out mids and lows while a single tweeter handles the high notes. Together they provide booming mobile output.

The 35 centimetre tall Laundry POD saves campers and road-trippers from dirty duds, using little water and no electricity. When washers crank the handle, gears spin the internal drum (containing up to six T-shirts and 5 litres of water) three times for every rotation. Drain the soapy water through the base, refill to rinse, and then spin dry.

The BungeeAir keeps iPhone owners from losing their phones, and their keys. A key fob and paired phone case connect on the long-range 2.4-gigahertz wireless frequency. If the devices separate by more than 15 metres, the pieces alert the user.

Milwaukee’s pliers can snip a screw or create a wire loop without the user ever having to change his grip. A wire stripper and a bolt cutter sit side by side inside the jaw of this spring-loaded needle nose.
