Abstract: Various implementations include a system for detecting a gunshot. The system includes a device for capturing acoustic data that is potentially sound emanating from an actual gunshot and a processor. The processor includes non-transitory, computer-readable medium including computer-executable instructions. The computer-executable instructions cause the processor to determine whether an acoustic sample contains an ultrasonic burst that corresponds to an ultrasonic signature of an actual gunshot having ultrasonic component sound frequency content in excess of 30 kHz. The acoustic sample is a portion of the captured acoustic data starting at or prior to an initial acoustic impulse within the captured acoustic data and ending at a predetermined sample length. The determination is used to identify an actual gunshot and distinguish it from that of a sound burst that is not an actual gunshot.

Abstract: This invention is a gunshot detection device that provides very reliable inside and outside real-time situational awareness of gunshot events, while reducing Gunshot Detection False Positives and Negatives.

Abstract: Systems and methods for detecting a gunshot event are disclosed. More particularly, systems and methods for detecting a gunshot event using the ultrasonic frequency distribution across a broad range of frequencies resulting from a gun's muzzle blast to determine whether an actual gunshot event has occurred and to minimize false positives and false negatives are disclosed. Yet further, systems and methods for determining the location of an actual gunshot event by utilizing the decay of the frequency distribution across a broad range of frequencies resulting from a gun's muzzle blast are disclosed.

Abstract: This invention provides a system and a method to manage the uploading of data files from multiple wireless field devices in multiple locations to multiple data storage servers through the use of location information.

Abstract: The device features one or more video cameras (13, 14, 15) linked to a computer (16) which analyses the output of the cameras to distinguish between normal movement and falls. Upward or similar movements, normally associated with a patient attempting to get out of bed are also identified. An alarm is activated at a remote attendant station when a fall movement is determined to have occured. The cameras and computer are situated as a bedside unit (11).
