摘要： A metal detection apparatus (9) is tested with a test device (7) having at least one test article (79), movable through a detection zone (60). The test article is moved through the detection zone along a first transfer axis (ca) and a first input signal is measured. A first threshold (th1) is determined, where an amplitude of the first input signal exceeds the first threshold (th1). Then, an identical test article is moved through the detection zone along a further transfer axis (ta; . . . ) and a further input signal is measured and a further threshold (th2; . . . ) is determined, where an amplitude of the further input signal exceeds the further threshold (th2; . . . ). The first or further threshold (th1; th2; . . . ) is selected in the signal processing path (4) whenever the test article is moved along the related transfer axis (ca; ta; . . . ).

摘要： The present invention relates to a magnetic controlled Bluetooth device and more particularly to a magnetic controlled Bluetooth speaker. The magnetic controlled Bluetooth device comprises a magnetic unit and a magnetic sensor. As another magnetic unit approaches the magnetic sensor of the magnetic controlled Bluetooth device, the magnetic sensor varies its output voltage in response to the magnetic field of another magnet. Thus, the magnetic controlled Bluetooth device can be turned on to execute a Bluetooth pairing process. Further, the magnetic unit of the magnetic controlled Bluetooth device can be used to approaches another magnetic sensor of another magnetic controlled Bluetooth device to turn on another magnetic controlled Bluetooth device.
