Abstract: A system, device and method facilitate accurate detection of gunshot events through spectrum analysis of impulse signals and/or evaluating impulse signal exponential decay amplitude and time values. In various embodiments, the device and system employ an acoustic sensor, one or more high-pass and low-pass filters, a threshold detector, a differentiator, a decay waveform shape generator, one or more comparators and one or more timers to facilitate detection of gunshot events and/or components of gunshot events.

Abstract: A sensor device, system and method can generate a profile of one or more detected substances in an environment, receive monitoring data from one or more of a group of sensors, and assess whether a heat-not-burn device activity event has been detected. In various embodiments, the sensor device includes a particle detection sensor and a gas detection sensor and a profile for heat-not-burn device activity is established with a threshold of detected particles and/or gases. In various embodiments, the profile for heat-not-burn activity is established with a threshold of gases that is not to be met or exceeded in order to generate a positive heat-not-burn detection.

Abstract: Embodiments of a sensor device, method and system employ a multiplicity of environmental sensors as a single monitoring and alerting mechanism, operable to provide a profile of any contaminant in terms of various gases and particles in the atmosphere, quantified in terms of relative concentrations. In various embodiments, the sensor device can comprise hardware and firmware elements, including an electronic control system, a case, a shield and a cover. The environmental sensors can be secured as part of the electronic control system and the shield can be formed so as to facilitate proper channeling of air and sound for effective operation.
