Person at risk rescue services alert having oscillating weight microgenerator current converting and monitored surveillance unit with surveillance unit/warning mechanism current charged battery fed

摘要

The protection mechanism (1) has an oscillating weight (10) transmitting energy to a microgenerator (11). The energy is converted to electrical energy and stored in batteries (12). There is a surveillance mechanism (21) which determines the microgenerator current in a set time, setting an alert (22) where no current is detected. Both the surveillance and warning mechanisms are fed by the battery.
