  • Patent number: 10627292
    Abstract: Indoor gunshot detection analysis is performed in the presence of a fire alarm. A gunshot sensor, which includes infrared and acoustic sensors, is used to detect an infrared pulse, whether the pulse originates from a muzzle flash or a fire alarm strobe. The infrared pulse is determined to correspond to a strobe occurrence. An evaluation determines that a gunshot did or did not occur based on the strobe occurrence. In another embodiment, a gunshot is detected while the fire alarm is occurring, where the gunshot occurs at a different time from the strobe occurrence and can be sensed by the acoustic sensor. A fire alarm strobe frequency and duration are determined, and further strobe occurrences are edited. Editing detection edits out a sensing time window by the infrared sensor. When the strobe stops, editing is eliminated, but if the strobe restarts, then editing is resumed.

    Abstract: A method for generating an extended underwater plasma. A first laser pulse is fired into a body of water to form an underwater optical filament coinciding with a low-energy plasma. A second laser pulse is fired into the water, targeted at the plasma. The second pulse heats the plasma, causing the formation of an extended superheated plasma volume in the water. The two laser pulses can be simultaneous or can be sequential, with the second pulse following the first pulse by up to the filament plasma lifetime. The extended superheated plasma creates an underwater acoustic pulse, wherein the duration, waveform and directivity of the pulse can be tailored by controlling the shape of the underwater laser-generated plasma.

  • Patent number: 8995229
    Abstract: Methods and apparatus determining a position of a submersible vehicle within a body of water are provided. A method comprises determining an initial position of the vehicle while the vehicle is at or near a water surface. The method further comprises coupling the vehicle and a base node to a weight and determining a position of the base node once the base node and vehicle have reached the floor of the body of water using acoustic modems of the vehicle and a surface vessel to aid in calculating the position as they descend, and acoustically transferring the at rest position on the seafloor from the vehicle to the node. The method further comprises decoupling the vehicle from the node and weight and determining a position of the vehicle based on the position of the base node and acoustic signals exchanged between acoustic modems of the vehicle and the base node.

  • Patent number: 8791701
    Abstract: Electromagnetic proximity detection method for a buried structure executed with a mobile detection device, including sensing an electromagnetic field emitted from the structure as an analog electrical signal and digitalizing the analog electrical signal as a digital signal, performed after or while filtering the analog and/or digital signal. The proximity of the buried structure is determined by analyzing the digital signal, wherein the detection method can be alternatively executed in at least two of the following modes of detection: Power-Mode of detection, Radio-Mode of detection or Active-Mode of detection. An additional Switching-Mode of operation includes a repeated sequential detection in at least two of the mentioned modes of detection and is done by automatic subsequent alternating of the mode of detection with a minimum rate of alternation that an area of detection is coverable by the at least two modes of detection in a single execution of the detection method.

  • Patent number: 8767511
    Abstract: A method for the global acoustic positioning of the USBL or SBL type of a marine or submarine target is more accurate than the method used by known USBL or SBL systems, while applying a network of sensors having the same material dimensions as those of these known systems. The method makes use of the movements of the network of sensors to apply principles of the processings by synthetic antenna. The principle of the synthetic antenna transposed to the present problem consists in using the signals received by the hydrophones of a physical antenna placed on a moveable platform at K different moments in succession, and therefore at K locations in succession in order to provide an estimate of the position of the beacon by virtue of an antenna of virtually greater dimensions.

  • Patent number: 8750076
    Abstract: To enable precise calculation of a propagation time of a direct wave which arrives the earliest from an ultrasonic emission source without being affected by a reflected wave. A plurality of ultrasonic signals generated based on a plurality of M sequences different from each other are propagated from a transmission side to a reception side, whereby the reception side executes processing of correlation between each model waveform of the plurality of M sequences and a waveform of each ultrasonic signal and detects a subsidiary peak of a correlation value appearing when both waveforms partly coincide with each other to, starting with the smallest one of subsidiary peaks detected by all the correlation processing, determine a plurality of corresponding M sequences.
