A new series of patent filings by Apple outlines attempts to modernize head-mounted displays (HMDs) that can be plugged into iPods or iPhones by decoupling the image generation components from the headsets themselves, which would pave the way for more lightweight and comfortable designs. via: AppleInsider
Here is the link to the filed patent.
Abstract: A head mounted display system is disclosed. The head mounted display system includes a remote laser light engine that generates laser light associated with a display signal. The head mounted display system additionally includes a head mounted display apparatus that is separated from the laser light engine and comprising a display unit that displays laser images. The head mounted display system further includes an imaging device coupled between the remote laser light engine and the head mounted display apparatus. The imaging device creates laser images from the laser light transmitted through an optical cable in accordance with the display signal. The laser images are delivered to the display unit in order to create display images that can be viewed by a user of the head mounted display apparatus.
So one day I may have a chance to work for Apple.

Time reported laser graffiti.
Artists James Powderly and Evan Roth recently went on a daring graffiti mission. The goal? Tagging New York’s Brooklyn Bridge. They waited for rush hour to die down and tried to be as incognito as people milling around bridges can be in this post-Sept. 11 world. Then, the duo fixed their crosshairs firmly on the bridge’s underside, and started etching out dozens — maybe hundreds — of tags on one of its massive supports. They held still as a police boat floated under the bridge. Later, they allowed passersby to pick up the equipment and try it for themselves. Yet, the next morning, there was nary a sign that Powderly or Roth — nor their towering graffiti art — had ever been there.
Vibrating people’s brains with laser beams could pinpoint the focus of epileptic seizures faster and more easily than the lengthy scans or surgery used today, US researchers say.
Epilepsy is the most common brain disorder and affects about 1% of the population. It occurs when nerve cells in a certain area of the brain fire more rapidly than usual, leading to seizures.
Only about two-thirds of people with epilepsy can be treated with drugs, with surgery the only option for the rest. Surgical cure rates are poor and recurrence rates high – especially for “neocortical seizures” that occur in the brain’s outer layers.

In the fight against speed detection equipment, the laser gun jammer is unique. This unit will jam the signal when a laser gun is being used to detect your speed. It includes the laser transponer modules, interface and display module with audio and LED alerts and is ideally suited for laser jamming on cars and trucks and will work on all laser gun systems. It melts aesthetically into the vehicles front, are small, hardly show and do there job better than any other. Using the latest state of the art technology, they will defeat all laser gun speed guns.

Have no idea how it works though. Post it here just for fun, don’t try it.
A UK-based company, 3D Laser Mapping, has developed robots equipped with lasers to automatically scan mines. Its latest mission was to create a 3D map of the San Jose silver mine in Mexico. More at ZDNet
A laser light show with a patriotic theme will replace Vienna’s traditional fireworks display this Fourth of July after an accident last year injured about a dozen spectators.
The Vienna Town Council voted Monday to spend as much as $22,000 on a contract with Baltimore’s Image Engineering to put on the display at the same field near Vienna Elementary School as years past.
