*Vision chip blends detection with image processing
(4:25 p.m. EDT, 08/03/99)
Blending an array of photo-detectors with on-chip digital image-processing circuits, researchers at the University of Tokyo have created an ultrafast sensor for industrial applications. The vision chip both acquires and processes images at 1,000 frames per second, enabling a robot arm equipped with a prototype sensor to grab for fast-moving objects without calculating trajectories.

*DNA To Help Nab Drug Dealers Red-Handed - Report
LONDON (Reuters) - A new test based on DNA science can tell if people have handled cannabis, but it is so sensitive that there are fears that innocent people could be incriminated, the New Scientist said Wednesday. It said researchers had identified DNA sequences within the part of the plant cell responsible for photosynthesis -- the chloroplast -- which are specific to cannabis sativa and are not found in any other species. The discovery by researchers at the University of Strathclyde in Glasgow makes it possible to take a swab from someone's hands and test it for the cannabis DNA sequences.``This test is as sensitive as you can ever get,'' Adrian Linacre, one of the inventors, told New Scientist. ''Theoretically, it could pick up the presence of just one molecule of cannabis DNA.'' Because the test multiplies the amount of DNA, it works on minute samples, unlike existing techniques. But this acute sensitivity is causing concern. Chris Evans, of Surescreen Diagnostics which markets drug testing kits, said the test could easily trap the innocent.``If you have been driving a second-hand car and a previous owner has been using cannabis, you could get enough on your hands to test positive,'' he told the magazine. Bank notes could also carry trace amounts of the drug. Linacre said he had calibrated the test so that only relatively large quantities of DNA gave positive results. He is now developing the test to detect the DNA profiles of different strains of cannabis, such as those grown in South Africa or Thailand. ``We will be able to use genetic evidence to link different batches of cannabis and trace them back to their original source,'' he said.

*A GameBoy, GameBoy Pocket, or GameBoy Color has software available with the
ability to turn your GameBoy into a RedBox (Toll Fraud Device) This software has been around for a while. These GUI based applications allow you use you GameBoy to make free long distance calls, crack answering machine passwords, and just use it as a tone dialer. Well the new GameBoy Color has an interesting feature, an IR port. As mentioned on HNN and elsewhere a few months ago there are vehicles that use IR as a locking mechanism. With currently available software you can now teach your GameBoy various IR codes including those to unlock vehicles. Wondering how you get these programs into your GameBoy? Well, Nintendo recently lost the court case against the person making and selling GameBoy ROMS which makes it real easy to transfer files around. Another example of how it is not the tool that is malicious but the user.
