Methods of ensuring safe use of electronic and electro-mechanical apparatus |
摘要 |
The safety methods warn the apparatus user to limit their use of the equipment, e.g. someone working at a monitor is warned to take a break after a specific time. The user is warned with a screen symbol, message or by a tone. The type of warning signal/image is pre-selected by the user. If the warnings are continually ignored the appts. is programmed to refuse further service until a break has been taken. Sensors monitor if the user is taking recommended exercise during the break by means of a sensor mat attached to the system to monitor movement, radio linked exercise appts., distance measuring appts. in an arm band. Pulse sensors are used to monitor low productivity/tiredness. Sensors in chairs are used to monitor the length of time watching television. A form of enclosure is placed over the equipment and secured by a mechanical or computer controlled time lock. Computers or computer based games can be provided with a facility to limit use.
