Definitions

  • a security device for a computer.
  • the security device may include means for detecting movement of the computer, which may, for example, comprise one or more tilt sensors or vibration sensors.
  • the security device may also include means for detecting tampering with the computer, which may be arranged to detect removal of the computer casing.
  • Fig. 3 is a side view of a mounting bracket
  • the low level output of the sounder device 30 serves as warning to the person who has moved the computer that the full alarm is about to sound. If, during the interval determined by the reset timer 28, there is no further movement of the computer or if the mains power supply is restored, the logic circuit 25 sends a third signal to the swept tone generator 29, which silences the sounder device 30. The security device is simultaneously reset to the active, quiet state. However, should further movement be detected with the mains supply disconnected, the full alarm will sound upon expiry of the predetermined interval.
