It’s only taken about a million years, but someone has finally decided that improvements are possible in automobile braking lights. Students from Virginia Tech have developed a new system that can show not just whether you’re stopping, but if you’re slowing down, when you’re about to stop, and how quickly you’re pressing the pedal. The concept uses an array of horizontally arranged LED lights — when you begin to slow, lights in the center glow orange, after a certain threshold side lights turn to red, and if you’re slamming on the brake, they’ll all flash red. The team, led by mechanical engineering Professor Mehdi Ahmadian, has plans for the system beyond the lab, though they speculate that it will be easier to add them as additional indicators on commercial vehicles at first. If this pans out, someday soon we may all be tailgating a totally psychedelic light show.

It’s always worth noting when a reviewer says that a device, “sets a new standard for image quality in a compact camera.” That’s PopPhoto’s conclusion after testing the Sigma DP1 with a DSLR-sized, FOVEON X3 CMOS sensor packing 14 megapixels. The image quality and color accuracy remained “stellar” right up to ISO 800 where other compacts shackled with tiny sensors begin to lose control of the noise. The biggest nits are with the sluggish 9-zone AF system, an unsophisticated flash, lack of image stabilization, and delays between shots. Fix those while whittling-back the $800 street price a bit and PopPhoto believes the DP1 could go mainstream.
