Claims24
A machine tool monitoring device, comprising:
- a detection unit for detecting a use situation of a machine tool, wherein at least one portion of the machine tool is used as a deflector for a transmitting and receiving signal of the detection unit, the detection unit being positioned such that the transmitted or received signal is directed or redirected at an angle of about 90 degrees by the portion of the machine tool used as a deflector.
A machine tool, comprising:
- a machine tool monitoring device comprising a detection unit for detecting a use situation in the machine tool, wherein at least one portion of the machine tool is used as a deflector for a transmitting and a receiving signal of the detection unit, the detection unit being positioned such that the transmitted or received signals is directed or redirected at an angle of about 90degrees by the portion of the machine tool used as a deflector.
A method of detecting a use situation in a machine tool, the method comprising:
- a detection unit transmitting a signal;
- using a portion of the machine tool as a deflector for the transmitted signal;
- the detection unit receiving the deflected signal;
- and
- detecting at least one parameter of human or animal tissue in the received signal for detecting the use situation;
- wherein the detection unit is positioned such that the transmitted or received signal is directed or redirected at an angle of about 90degrees by the portion of the machine tool used as a deflector.
