The present disclosure provides a dual energy backscatter system that uses low energy and high energy radiation sources for object detection, characterization, and defect detection. The dual energy backscatter system may also be used to determine the internal structure of the object. The dual energy backscatter system may be used to detect objects underwater, including objects buried or partially buried in sand or sediment.

Object detection and characterization using dual energy backscatter technique

After determining that a gunshot has been fired, particularly indoors, the method of the invention is employed to determining the number of gunshots fired by analyzing consecutive windows of time over a certain time period. That is, after it is determined that a gun has been fired, the method is employed to identify that the gun is an automatic or rapid fire weapon by quickly counting the number of rounds shot over short periods of time. This information can be used to provide shooting details, both in connection with notifying emergency personnel and enabling the personnel to assess details of the shooting incident.

Method for acoustically counting gunshots fired indoors

A system and method for acoustically detecting the firing of gunshots indoors employs multiple microphones () which are utilized individually and in combination to detect sounds inside a building or other structure and, upon sensing a loud impulsive sound which is indicative of a gunshot, processing signals from both microphones () to determine if the sound is that of a gunshot. The system and method relies on the acoustic signature of the noise as collected, with the acoustic signature being analyzed to arrive at values which are then compared to adjustable levels that signify a gunshot.

System and method for acoustically identifying gunshots fired indoors

Method and system for detecting multiple alarms triggered by the same event and suppressing the duplicate detections, reducing false alarm rate. The first sensor to be activated is identified via a timestamp associated to the activation, then it is identified whether the other sensors have been activated by the same event. In particular a plurality of microphones is deployed in separate rooms to detect gunshots from firearms in a indoor setting.

System and method for identifying and locating sensed events

A system and method are disclosed for determining a constituent and/or concentration of a solid dissolved in a liquid. In one embodiment, a method is provided to interrogate and identify a liquid in a medical container.

System and method for solution constituent and concentration identification

A system and method are disclosed for interrogating a liquid in a container. In one embodiment, a method is provided to interrogate and identify a liquid in a medical container.

Liquid scanning system and method for IV drug verification and identification

A system and method are disclosed for interrogating a liquid in a container. In one embodiment, methods are provided to interrogate and identify a container material type and a liquid within a container.

Container screening system and method

A system and method are disclosed for interrogating a liquid in a container. The liquid sample, such as drugs in a liquid base, is identified based on a radio frequency and/or ultrasonic measurement.
