| 摘要 |
<p>The present invention relates to a warning device for indicating dangerous circumstances, especially for helicopters, having a signal receiving means for receiving and processing an operational status signal; a signal comparison means which compares the received operational status signal against predefined criterion; a monitoring signal generating means which generates a monitoring signal when the operational status signal meets said criterion; a monitoring transmission signal transmitting means which wirelessly emits said generated monitoring signal; a monitoring transmission signal receiving means which receives said emitted monitoring signal; a monitoring transmission signal comparison means which analyzes whether said received monitoring transmission signal meets predefined monitoring transmission signal criteria; and an output means which emits an output signal when the monitoring transmission signal meets said criteria, whereby said receiving means, said monitoring transmission signal comparison means and said output means are worn by a user and said output signal is immediately perceived by the user.</p> |
