Abstract
Official abstract text for this publication.
A method is provided which protects persons in the vicinity of a high frequency (HF) field-emitting device, in particular a European train control system (ETCS) antenna of a rail vehicle. In order to be able to reliably protect persons from radiation that is detrimental to one's health, the device is held in or switched to an OFF state by an uplink for a limited period of time, the ON/OFF state being optically and/or acoustically signaled.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for protecting persons in a vicinity of a device emitting a high frequency field, which comprises the step of: holding or switching the device in an off state for a limited period of time by means of an uplink, wherein the on/off state is signaled at least one of optically or acoustically. 2. The method according to claim 1 , wherein the device is a European train control system of a rail vehicle. 3. A system for protecting persons in a vicinity of an apparatus emitting a high frequency field, the system comprising: a personal safety apparatus having a control device for switching off the apparatus emitting the high frequency field, a circuit for limiting a period of time for which the apparatus emitting the high frequency field is switched off and a signaling device for outputting an optical and/or acoustic signaling of an on/off state of the apparatus emitting the high frequency field. 4. The device according to claim 3 , wherein said personal safety apparatus is carried by a person and has activation means for manual activation of said personal safety apparatus.
