I am an ancient old pensioner (92) and I recently collapsed in my bungalow where I live alone and stayed on the floor until discovered. In hospital the Red Cross suggested an electronic emergency service which consists of a wrist band transmitter and shelf receiver which sends an alarm to a monitoring station. Works fine but I now discover it costs an initial £25.00 then £15.96 per month.
There are thousands in need out there who cannot afford this but who live alone and do need a rescue system. We need a simple low cost automatic " person down" alarm that costs a little and is a one-off purchase. I think I have the idea for a solution but it will need a simple electronic circuit.
The circuit needs to flash a very bright bulb when triggered until manually stopped. This circuit does absolutely NOTHING for a pre-determined time - say 24 hours. If an obvious button is pressed it continues to do NOTHING for another 24 hours. If the button is NOT pressed then after the allotted time it goes into action and the strong bright light goes into full flashing mode. A second button would stop the action if it was accidentally triggered and a third button would activate the device if the lonely person was in trouble and could reach it before the device went automatic. Mains operated with an automatic battery back-up if the mains connection failed, with automatic trickle charging when mains connected.
Housing would be a simple box shape about 12 inches square and a depth of about four inches to sit on a windowsill, perhaps simple legs if height was needed. The front 12" square would have a cut-out board with large HELP. The powerful light, red bulb or coloured film over cut-out would illuminate the HELP. If the lonely person was in good shape and always remembered to press the " I'M OK" button then the device would never come to life.
If the lonely person was forgetful and allowed the device to go to alarm when nothing was wrong - then so-what! At least their loneliness would be broken by visitors; and the visitors should not care about the slight inconvenience of helping an old lonely person. Might trigger some good Samaritan to check every day.
I belong to a local "MensShed" and we could knock up a prototype if somebody could work out a circuit. If we could produce a working prototype then it might not be difficult to find a manufacturer and perhaps the Red Cross and AGE to distribute it.
I am a life member of the RAF Association and the top brass at the RAF Benevolent fund have show interest to supply to RAF veterans who are in need. Any help available?
