摘要:
Disclosed are methods and systems for detection of a discharge of a projectile from a firearm. An example method for detection of a discharge of a projectile from a firearm may commence with recording environmental audio by at least one microphone associated with at least one electronic device. The method may continue with triggering, by a processing unit associated with the at least one electronic device, based on predetermined triggering criteria, a frequency analysis of the environmental audio. The analysis may be performed to determine a likelihood of the projectile being discharged from the firearm. The method may further include transferring, by a data transfer unit associated with the at least one electronic device, results of the frequency analysis from the at least one electronic device to a data storage unit for post-processing.

A safety system includes an electromagnet positioned in an area. A power controller is coupled to the electromagnet to supply power to the electromagnet in accordance with an event. A trigger mechanism configured to trigger the event when the area is traversed by a person with a weapon such that upon activation of the electromagnet a magnetic force is generated capable of attracting the weapon to make continued use difficult or impossible within the area.

A tear gas-based enhancement to a fluid bed security system implemented for the purpose of inhibiting unauthorized entry or access and to provide additional time for threatened individuals to evacuate or escape a hostile assembly at the perimeter of a secured area. The system provides for the reliable and controlled application of a specified concentration of tear gas emitted in conjunction with fluidizing gas distributed through a fluid bed configuration comprising a gas distribution piping array and a plurality of fluidizable granular solids in a surrounding relationship to the gas distribution piping array.

摘要:
A method for accurately determining whether a response tool will be effective for responding to a given enemy threat object. Embodiments described herein provide a method and system for responding to a threat object, for example, negating missile threats. Embodiments may include validating effectiveness of a response to the threat object. Other embodiments may include verifying the continued effectiveness of a response to the threat object. Further embodiments may include providing feedback to re-perform the method for responding to the threat object. The system may include a mathematical method, and associated algorithms, to assess, in an automated fashion, the performance of non-kinetic techniques with respect to negating the threat object.

Methods, apparatus and systems for computer-aided determination of quality assessment for locate and marking operations. In one example, a quality assessment decision is solely under the discretion of a human reviewer, albeit facilitated in some respects by computer-aided display of information, and electronic record keeping and communication functions associated with the quality assessment result(s). In another example, information related to a locate and marking operation is electronically analyzed such that a quality assessment is not based solely on human discretion, but rather based at least in part on some predetermined criteria and/or metrics that facilitate an automated determination of quality assessment.
