Computerised Tomography

Richard Tanke Finished Proto's

A Computerized Tomography scanner or CT-scanner is non-invasive and non-contact diagnostic tool used as a common make-visible tool by most middle and larger hospitals. It uses X-Rays for transmitting the human body and sophisticated mathematics for calculating the density of the object irradiated. The 2D pictures of organs, tissue, veins and other objects in the human body are well known …

True 3D Tomography

Richard Tanke Finished Proto's

Normally CT shows 2D pictures of planes through the object (the mathematical algorithm is called the 2D Radon transform, after the Hungarian scientist Radon who created the mathematics as early as 1917 !). Pinhole detectors measure pencil-like beams of radiation. A 3D image database can be formed by stacking the 2D picture planes behind another. But only few people known …

Total Communication

You know Short Message Service of course. Or Texting? The mobile telecom providers were lucky that they had an unoccupied small bandwidth left over that could be used as a 120 character max. message service. It developed rapidly and became a gold mine. But for the deaf and hard-of-hearing users it wasn’t. For them the messages are relatively long and …

Stair Walking Aid

Richard Tanke Finished Proto's

Many elderly and handicapped people need a helping hand when climbing a staircase. Allthough they are strong enough they feel insecure. Elderly people who live alone must move to a one-level home or might go for a stairlift. But changing to another address is unwelcomed in many cases and a stairlift is expensive, it does not stimulate movement, and will …

Speechreading (lipreading)

Richard Tanke Finished Proto's

Speechreading is sometimes confused with lip-reading. But it is more; it uses the expression of the speakers face, movement of the limbs, his posture and even gait. It is used by the deaf and severely hearing-impaired people. But many use it along natural signing or sign systems. Speechreading can improve speech recognition; investigations show that 15-20% of the information transferred …

Total Energy Turbine for Domestic Use

Richard Tanke Finished Proto's

In 1999 a great Dutch inventor/scientist, dr. Gus Witteveen, approached us with a really revolutionary idea for a highly energy-efficient microturbine. This turbine concept, not bigger than a fist, would meet the highest thermal efficiency in it’s class. Up to 40% was theoretically possible. This is astonishingly high for small turbines normally not exceeding a few percent. Most engineers didn’t …

Living Sportstrainer Balance Bike

Richard Tanke Finished Proto's

Do you like home training on a bike? Or exercising in a sportschool on a kind-of-bike with a TV-monitor in front of you? Of course not; it is boring, it’s only cardio. It is not biking. It improves a little if the monitor shows virtual reality exercises and existing wellknown race tracks like Alpe D’Huez or Tour de France. But …
