The Resc-hue Lite Line is a fire-resistant and waterproof flexible light hose, or safety line, using electroluminescence, that shows the "life-line" in difficult lighting conditions, in the event of an accident.  Invented by Robert C. Kelly, it's designed for firemen and rescue workers.  It gives 360 degrees illimination and can support up to 10,000 pounds.  Applications include providing lighted guidance to firefighters finding their way out of a burning building, lighting the path for campers or underwater divers.

The Liperator

Telephone Aid for the Hearing-Impaired


The Liperator is a hearing aid that converts voice to lip movements on a video screen to help the hard-of-hearing work out what is said over the telephone, with a bit of lip reading.  It's invented by an 80-year-old gentleman Robert P. Slager.  After his hearing loss, he began to learn lip-reading to assist his hearing, but that is no use over the telephone, which prompted him to invent the Liperator.  The technology can be adapted to any language.  Dick remembers seeing a device with a similar idea years ago - for converting radio news to lip movements.

Neither won the 2006 Grand Prize, which went to the Strawjet - a farm implement that processes straw into mats which are then cast as columns and beams, or building panels or building blocks (similar to the use of fibreglass).  It's now got a website of its own, at strawjet.com.
