Engineers at Mountain View, Calif.-based SST have come up with technology that uses acoustic sensors to help police pinpoint the exactly location of a gunshot as soon has it goes off.

SmartPlanet visited the San Francisco Police Department to see SST's gunfire-detection software in action.

A U.K. company is now unveiling what it calls the world's first prototype handheld device that doubles as a fingerprint scanner and drug testing device.

In a matter of minutes, the portable device can detect the presence of a wide range of drugs using dyed antibodies that, as we reported back in July, stick to metabolites in the sweat of the fingerprints and change color depending on the presence of drugs.

"The launch of this prototype is a significant milestone," Paul Yaltes of development firm Intelligent Fingerprinting said in a statement. "There has already been … Read more

The bottom line: Following on last year's big overhaul, Trend Micro makes a series of smaller changes to this year's Titanium security suites. AntiVirus Plus contains the core features, but it's really on a level with free competitors--and that's a hard sell.

Review: Last year was a headliner for Trend Micro's security suites. Overhauled with a lightweight interface and cloud-based detection, and rebranded as Trend Micro Titanium, the changes made the suite competitive again. The 2012 version builds on those improvements, so this year doesn't have a lot of big changes. Still, there are … Read more

Likasoft calls Polyglot 3000 an automatic language recognizer, which is an apt description of this specialized tool. It's similar to automatic translators in that it analyzes the language of text entries, but instead of translating the text, it identifies and displays the language, including confidence in the match expressed as a percentage. It handles more than 470 languages.

Polyglot 3000 has a very simple interface and an equally simple operation. It has a text entry field for typing or pasting text to identify, or you can load Unicode or ANSI text files directly into the program. It has but … Read more

How often do you see guitars equipped with lasers?

M3i Technologies has come up with a guitar that uses lasers to record chords even before your fingers touch the strings. Talk about enhanced precision.

The instrument makes use of Laser Pitch Detection (LPD) technology. A set of laser diodes are placed on the bridge of the guitar and each string has its own laser beam extending across the frets. Once your finger passes through the light, the system in the guitar takes note of the laser beam's length and calculates the string's pitch.

Theoretically, these signals could be used to control just about anything (Pac Man, anyone?) or used as a controller for music-based games such as Harmonix's Rock Band.
