A firearm includes a barrel portion, a slide, and a frame. The frame includes a grip, and the grip includes a magazine chamber and a rear surface adjacent the slide. At least one sensor is carried by the grip, and the at least one sensor adapted to sense a state of the magazine detachably received in the magazine chamber corresponding to a number of cartridges of ammunition remaining in the magazine. A display is carried on the rear surface of the grip, and the display includes a plurality of illuminating devices. The display is operatively coupled to the at least one sensor and is operable to visually present the number of cartridges of ammunition remaining in the magazine by illuminating at least one of the plurality of illuminating devices.

Systems, methods, and computer program products for detecting, locating, and identifying gunshots. In response to detecting a discharge of a firearm, a discharge alert indicating one or more characteristics of the discharge is transmitted to a gunshot location system. The one or more characteristics of the discharge are compared to one or more characteristics of one or more gunshots detected by the gunshot location system based on acoustic signals received at one or more listening stations. In response to finding a match between the one or more characteristics of the discharge and the one or more characteristics of acoustically detected gunshot, the gunshot is associated with the firearm.

The invention relates to a firearm analysis device for determining parameters which are indicative for a firearm from a shot which has been discharged from the weapon, as well as a corresponding method, a corresponding firearm and a computer program product. The device comprises a voltage generating unit which generates an alternating voltage (Ue) during a counter-recoil travel and/or recoil travel of a movable weapon part occurring during a firing. The device is characterized by a signal processing unit which generates a measurement signal (IN.sub.+) from the generated AC voltage (Ue), a signal evaluation unit which determines a first time point and a second time point during the counter-recoil travel and/or recoil travel of the movable weapon part, and a time determination unit which determines a time period duration between the first time point and the second time point.

The present invention provides for systems, devices and methods for weapons modification to allow for use of real weapons in a simulated and augmented environment without exposing participants in the simulated and augmented training to risks of live ammunition. Embodiments of the invention provide an inexpensive and easily attachable/detachable appended system for the weapon which modifies or applies to a weapon in a simple fashion, and is capable of sensing necessary data for use in a simulated or synthetic training experience, and providing audio or tactile feedback to the firer, without rendering the weapon incapable of live fire use by simple detachment of hardware. Embodiments of the invention further provide an inexpensive and easily attachable/detachable weapon modification system that can provide all beneficial data capture, recording and transmission from a live fire weapon to either a simulated training system for processing, or other field use recording system.

Systems and methods are provided for weapon monitoring, including a weapon measurement system with one or more sensors that record longitudinal operational information of a plurality of weapons and are used to produce a plurality of signals, a connection point that receives the plurality of signals within a deployment location, a server device running application software that uses the plurality of signals received from the plurality of weapons to detect and store longitudinal situational state data of each weapon of the plurality of weapons, and a machine learning system that uses the longitudinal situational state data to calculate a weapon system failure state.

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.

Systems and methods are provided for combining video and virtual reality presentations, including a server device running application software that receives sensor signals at a connection point from a plurality of assets within a deployment location and processes the signals to generate a virtual reality depiction of the deployment location, and a graphic user interface presenting a field of view of the virtual reality depiction of the deployment location, where the virtual reality depiction is combined with video derived from the deployment location in the graphic user interface presentation.

A portable camera may be activated in response to the activity of a firearm. Furthermore, an individual who discharged a firearm may be identified. Furthermore, information related to the firing of a firearm may be recorded, assessed, identified and transmitted. Furthermore, the status of an implement at a mount may be monitored. Furthermore, a charging device for delivering electrical power to components of a firearm may be used. A communications channel may be established between a firearm telematics sensor and a video camera, optionally by means of intermediary devices. A communications channel may be established between a mount (e.g., holster) telematics device and local and/or remote monitoring service components, optionally by means of intermediary devices. When the telematics sensor detects that its associated firearm has been removed from a holster, is in motion, or is being discharged, the telematics sensor may signal the video camera to initiate recording.
