Wide Area Augmentation System

WAAS, or Wide Area Augmentation System is a GPS augment being developed by the American Federal Aviation Authority to network together air-based, ground-based and satellite based GPS stations to triangulate precise positions from all of them, enabling a reliable GPS fix in three dimensions rather than just two.

WAAS corrects for GPS signal errors caused by ionospheric disturbances, timing, and satellite orbit errors, giving accuracy in X, Y, and Z axis accurate to within 3 metres, in real-time. This makes it ideal for fast-moving objects such as planes, to track their precise location constantly.

As a nice side-effect, WAAS is able to report on satellite conditions. If one drifts out of orbit, the system picks this up immediately as its GPS telemetry for other objects disagrees with the rest of the network stations.

WAAS is compatible with basic GPS signal structure.

Whilst WAAS is only applicable for the North American continent, other geographic areas are developing their own systems, which are inter-compatible. . In Asia, it's the Japanese Multi-Functional Satellite Augmentation System (MSAS), while Europe has the Euro Geostationary Navigation Overlay Service (EGNOS).

The Difference between FPS and Lag
Participants in modern internet-controlled, heavily graphics-orientated virtual worlds often confuse fps and lag. When an area cluttered with graphics, and a complex drawing area slows down, all too often people say that the area is laggy, or their Internet connection is not sufficient to handle it. This is patiently untrue, and continued perpetuation of this idea leads people to invest in hardware they do not need, which has no effect on the problem.

If you have ever played the original Zelda games, then you will be familiar with what Graal is. This top-down 2D world system uses an almost infinite combination of square areas one and two screens wide, which slot together to form a world.

The Dextroscope is a holographic display system designed specifically to help surgeons visualize and practice on the area to be operated on, prior to actual surgery.

EFIT-V and personalised avatars
EFit-V is one of the newest tools in the police arsenal. A replacement for sketch artists and the electronic EFit system. Rather than concentrate on how wide a nose is, or how far apart the eyes are, whilst it still has that capability, the software takes a new approach, and creates photorealistic faces whilst it is at it.

Large Image Display: Prosthetic Jaw Hinging
One of the most important aspects when working with any skeletal system, is the joint where bones connect. If you don't get this area right, then bone will grind against prosthesis, and the bone is likely to take critical damage first. You inflame a joint, that did not have a problem in the first place, and spread further complications throughout the body.

Large Image Display: The Stepford Wives: Robo Dog 3000
Here we see the lovable disaster area that is Robo Dog 3000. As we find out much later in the film, Robo is a cyborg, much like the other members of Stepford. AA champion terrier's brain plus a minimal life support system, is hidden inside that shell, and hooked to considerable neuroprosthetics. This allows the dog to behave and think like a normal dog, whilst appearing to be fully robotic.
