Abstract |
AB |
[EN] The baby sitter alarm comprises a transmitter positioned within the child's room and responding to the noise level and duration to transmit a signal to a separate receiver, causing it to provide the alarm signal. The response thresholds for the sound level and duration are both adjustable. The transmitter is suspended above the child's cot, with the suspension wire acting as the antenna. It has a directional microphone coupled to an evaluation stage for providing the signal initiating the signal transmission. The receiver is designed to fit into a pocket so that it can be carried around and it converts the received signal into a bleep tone. |
