Abstract (en)
[origin: WO9323833A1] A device for detection and information transmission comprises a first unit (1) for transmitting and receiving microwaves and shows at least a first antenna (6). It is primarily characterized in that the unit is so arranged that within a first antenna lobe (12, 19) through Doppler shift of a transmitted first microwave signal it detects movements in an object. The unit is further arranged to communicate within a second antenna lobe (7, 13, 20) with a so-called transponder.
