Title: A device for the detection and location of sound waves
Inventor: BSCHORR OSKAR
IPC: H04R1/40
Filed: 1990-07-11
Abstract: In order to increase the noise gap between incident- and interference signals, in particular wind noise, microphone (5) is arranged inside a resonator (2) which is tuned to a certain resonance frequency. The resonator can also be a silator (2a). The impedance break at the resonance frequency allows alignment to the impedance of the surrounding medium so that optimal large antenna cross-sections can be used. The sensitivity of the microphone is also increased by the sound- pressure increase at resonance. Since the shape of the resonators can be freely chosen, they can be integrated into existing vacant spaces, for example wings of search drones. <IMAGE>

Patent GB-2249836-A (GB)
Title: Bomb detecting vehicle security system
Inventor: DUNCAN ALEXANDER WILLIAM
IPC: G01V3/10
Filed: 1991-08-28
Abstract: A vehicle security system comprises first and second conductive loops (A and B) for attachment to a vehicle (C) in substantially parallel relationship with a gap (D) between them. Each loop is connected to an associated first amplifier (1, 2) the outputs from which are connected to a differential amplifier (3) which is arranged to sum the output signals received from the first amplifiers. The output from the differential amplifier (3) is connected to a threshold detector (4) which sets a latch (5) to store an alarm condition when a moving magnetic field is detected. The alarm condition signal is interrogated remotely by, for example, an infrared remote control link (8, 11) to activate an alarm (7). As a moving magnet field is passed across the gap between the two loops (A, B) a voltage is induced in each loop and the first amplifiers (1, 2) detect the induced voltage and the differential amplifier (3) determines a phase shift in the two voltages. This phase shift indicates that a moving magnetic field has passed over the gap between the two loops (1, 2), and indicates the possibility of a magnetic bomb device having been attached to the vehicle.
