摘要： Systems and methods are disclosed for locating a weapon fire incident such as an acoustic transient from a gunshot, explosion, weapons launch, etc. In one exemplary implementation, there is provided a method of locating the incident from a combination of propagation phenomena including a discharge time of the weapon fire incident. Moreover, the method may include obtaining a first propagation parameter of the incident from one or more first sensors, obtaining the discharge time from another sensor, and processing the data to determine a location using a common time basis among sensor measurements. According to further exemplary implementations, the discharge time may include a transient event that has a different propagation velocity than that of sound in the atmosphere.

摘要： Systems and method are disclosed for processing signals. In one exemplary implementation, a method may include transforming initial bullet data associated with one or more sensors into a set of discrete pulses, dividing the discrete pulses into pulse subsets, generating, for the subsets, time domain representations of the pulses, wherein the time domain representations include waveforms having pulse features, and processing the time domain representations to determine alignment between one or more of pulse features, pulses, pairs of channels, and/or pairs of sensors. One or more further implementations may include determining identity of pulses in association with a matching process performed as a function of the alignment, as well as, optionally, other pulse processing features/functionality.

摘要： A gunshot location system computes candidate gunshot locations from angle-of-arrival information and time-of-arrival information provided by acoustic sensors. In addition to an angle, each sensor calculates an angular uncertainty from impulses received at four or more microphones having rotational symmetry. An intersection of one or more time-of-arrival hyperbolas with one or more angle-of-arrival beams is used to determine a candidate gunshot location. In simple environments, a location can be confirmed with just two sensors allowing sensor density to be significantly reduced, while in complex environments including reflections, blocking, and interfering acoustic events, the additional angle-of-arrival information improves location accuracy and confidence, allowing elimination of candidate locations inconsistent with the combined time-of-arrival and angle-of-arrival information.

摘要： Systems and methods are disclosed for archiving and processing information from an array of remote sensors. Aspects of the innovations may be incorporated, for example, into a gunshot detection and location system to preserve sensor information surrounding a gunshot event for later review or analysis. According to one implementation, an exemplary method may including sampling video signals from the sensors and storing samples in a storage device such that the video signals detected from the sensors may be selected and/or reproduced. Other exemplary implementations may include creating a searchable database wherein the video information is indexed as a function of parameters, which may include data associated with the capture of video signals such as sensor information, time of capture, etc.

摘要： An electroplating apparatus and method reduces oxidation of thermodynamically unstable and oxidizable ionic species in an electroplating solution to deposit complex magnetic alloys onto substrates. In one embodiment, the electroplating apparatus comprises an electroplating cell in which oxidation of oxidizable anions and cations is reduced. The cell comprises (i) an anode compartment comprising an anode and anolyte solution; and (ii) a cathode compartment comprising a cathode and catholyte solution containing oxidizable plating anions. A cation-selective semi-permeable membrane separates the anode and cathode compartments. An electrical power supply is used to maintain a voltage across the anode and cathode. Upon application of the voltage to the anode and cathode, transport of the oxidizable plating anions, and to a lesser degree cations, to the anode is substantially blocked by the cation-selective semi-permeable membrane, thereby reducing oxidation of the oxidizable anions and cations at the anode. The concentration of the anolyte and catholyte solutions can be tailored, and an inert gas can be maintained above the solution surface in the cell, to further reduce oxidation of the oxidizable plating ions in the cell.

摘要： A gunshot location system computes candidate gunshot locations [314] from angle-of-arrival information [304, 308] and time-of-arrival information [312] provided by acoustic sensors [300, 302]. In addition to an angle, each sensor calculates an angular uncertainty [306, 310] from impulses received at four or more microphones having rotational symmetry. An intersection of one or more time-of-arrival hyperbolas with one or more angle-of-arrival beams [322] is used to determine a candidate gunshot location. In simple environments, a location can be confirmed with just two sensors allowing sensor density to be significantly reduced, while in complex environments including reflections, blocking, and interfering acoustic events, the additional angle-of-arrival information improves location accuracy and confidence, allowing elimination of candidate locations inconsistent with the combined time-of-arrival and angle-of-arrival information.
