Get an attractive automatic nighttime motion-sensing light without having to do any wiring with a Cordless Motion Activated Outdoor Sconce. This battery powered sconce has dual bright LED’s to illuminate the area for 20 seconds after the fixture detects motion up to 22′ away. It’s weatherproof and it runs for one year on 4 C batteries. No need to hardwire it in or place it near an outlet- and unlike other motion detecting outdoor security lights, it doesn’t look like a spotlight outside a prison. Attractive and useful- just like you.

Caltech laser accelerometer research may bring fine-tuned position tracking, grocery ads
One way that sensors can track your position without using an array of satellites is by measuring your acceleration as you move around -- but unless you're piloting a jumbo jet, current devices aren't very accurate. Researchers at Caltech hope to change all that with a new, ultra-sensitive accelerometer they developed, which uses laser light to detect motion changes. The scientists managed to shrink a so-called large-scale interferometer down to micro-scale sizes, creating a device "thousands of times faster than the most sensitive sensors used today." That could allow a smartphone with such a micro-sensor to detect your exact position even while inside a grocery store, and flash "ads and coupons for hot dog buns" while you're in the bread aisle, according to Caltech. All that sounds good, but we can perhaps think of more inspiring uses for the new tech.

Other lights may simply turn on when motion is sensed but the Motion Tracking Security Light. goes above and beyond that. This light automatically swivels to follow people as they move around your yard. The light detects body heat up to 40 feet away with it’s wide angle infrared sensor which even has extra sensors aimed below the unit. It’s lit by LED lights and can be wall or eave mounted and hardwired directly to an existing electrical box. The swiveling allows this light to offer more coverage than a normal light and a moving light can go a long way towards warding off trespassers from your yard.
