Detecting intruders

An intruder detection system is arranged to measure ambient air pressure in an enclosed space at frequent periodic intervals and to actuate an alarm when the sensor measures an ambient air pressure at a value substantially different from a reference value, which reference value is arrived at on the basis of the historical measured values themselves. The system therefore self compensates for natural slow changes in ambient air pressure. ...

Intrusion detection system with signal recognition

Burglary alarm

In order to detect pressure fluctuations when a window or a door is opened, a detector (5) which is sensitive to pressure in the infrasonic range is present, downstream of which detector (5) a signal processing circuit (10, 11) for forming a signal which is dependent on pressure changes is connected. The detector (5) is preferably composed of a ferromagnetic crystal, for example from LiTaO3. The housing (1, 12, 14, 15) for the detector (5) can be partially formed from a diaphragm (15) for the transmission of pressure fluctuations. <IMAGE>

Apparatus for detecting presence of person inside room having door

An apparatus for detecting the presence of a person or persons inside a room having a door. The apparatus comprises a pyroelectric infrared sensor and a piezoelectric air pressure sensor. The infrared sensor detects movement of a person and produces a signal indicating the movement. The air pressure sensor detects opening and closing of the door and produces a signal indicating the opening and closing. A logic device including monostable multivibrators, AND gates, and an OR gate is connected between the outputs of the two sensors. When the signal indicating the movement is applied to the logic device later than the signal indicating the opening and closing, the logic device produces a signal indicating the entry of a person. When the signal indicating the opening and closing is applied to the logic device later than the signal indicating the movement, the logic device produces a signal indicating the exit of a person. These signals are processed by the logic device to know the presence or absence of a person.

Burglar alarm system

In order to simplify the outlay, differences in atmospheric pressure which occur upon opening of doors and windows and propagate in the entire building are evaluated by arranging for the air flowing into a compensation chamber to be guided through a flow channel past a heated, temperature-dependent resistor, which is thereby cooled. Designing the flow channel so that it principally retains the warm air bubble produced at the temperature-dependent resistor against the latter permits preference to be given to a specific flow direction. Soundwaves of excessive intensity can be attenuated by an attenuation chamber; remote control via an air pressure line is possible.
