New Ford system helps warn police of approaches

| Saturday, July 20, 2013, 12:01 a.m.

Police could soon be getting some extra backup — from their cars.

Ford Motor Co. has a new surveillance system for police cars that automatically sounds a chime, locks the doors and puts up the windows if it detects someone approaching the car from behind. The system — which Ford is patenting — is the first of its kind.

“It's like insurance. You hope you never need it. But if you do, it gives the officer a few extra seconds of warning,” says Marc Ellison, vice president of operations at Auburn, Calif.-based InterMotive Inc., which helped Ford develop it.

Backup cameras and sensors usually work only when a car is in reverse. The new system allows an officer to use them while the car is parked. An image from the backup camera is beamed onto the rearview mirror. If someone comes too close, four sensors on the rear bumper will detect them.

We moderate comments. Our goal is to provide substantive commentary for a general readership. By screening submissions, we provide a space where readers can share intelligent and informed commentary that enhances the quality of our news and information.

While most comments will be posted if they are on-topic and not abusive, moderating decisions are subjective. We will make them as carefully and consistently as we can. Because of the volume of reader comments, we cannot review individual moderation decisions with readers.

We value thoughtful comments representing a range of views that make their point quickly and politely. We make an effort to protect discussions from repeated comments either by the same reader or different readers

We follow the same standards for taste as the daily newspaper. A few things we won't tolerate: personal attacks, obscenity, vulgarity, profanity (including expletives and letters followed by dashes), commercial promotion, impersonations, incoherence, proselytizing and SHOUTING. Don't include URLs to Web sites.

We do not edit comments. They are either approved or deleted. We reserve the right to edit a comment that is quoted or excerpted in an article. In this case, we may fix spelling and punctuation.

We welcome strong opinions and criticism of our work, but we don't want comments to become bogged down with discussions of our policies and we will moderate accordingly.

We appreciate it when readers and people quoted in articles or blog posts point out errors of fact or emphasis and will investigate all assertions. But these suggestions should be sent via e-mail. To avoid distracting other readers, we won't publish comments that suggest a correction. Instead, corrections will be made in a blog post or in an article.
