PROXIMITY SENSING METHOD, PROXIMITY SENSING APPARATUS AND MOBILE PLATFORM USING THE SAME
First Claim
1. A proximity sensing apparatus, comprising:
- an encoded signal transmission unit, for transmitting an encoded signal;
an interference signal transmission unit, for transmitting an interference signal;
the interference signal interfering with the encoded signal to generate an interfered signal; and
a reception unit, for receiving a sensing signal and transmitting the sensing signal to a signal processing unit electrically connected to the reception unit;
the sensing signal being either the interfered signal or the encoded signal;
wherein, the signal processing unit determines whether the sensing signal matches the encoded signal, and outputs a proximity signal when the sensing signal does not match the encoded signal.

Abstract
A proximity sensing apparatus is provided. The proximity sensing apparatus includes an encoded signal transmission unit, an interference signal transmission unit and a reception unit. The encoded signal transmission unit transmits an encoded signal, and the interference signal transmission unit transmits an interference signal. The interference signal interferes with the encoded signal to generate an interfered signal. The reception unit receives a sensing signal and outputs the sensing signal to a signal processing unit. The sensing signal is either the interfered signal or the encoded signal. The signal processing unit is electrically connected to the reception unit, and determines whether the sensing signal matches the encoded signal. The signal processing unit further outputs a proximity signal when the sensing signal does not match the encoded signal.
