Systems and methods for weapon event detection

A device attachable to a firearm, the device comprising:

• a pressure sensor configured to sense pressure generated from the firearm and provide a corresponding signal;
• a weapon movement sensor configured to sense at least one movement of the firearm and provide a corresponding signal;
• at least one processor;
• memory comprising computer instructions, the computer instructions configured to, when executed by the at least one processor, cause the at least one processor to determine an event of the firearm based on the corresponding signal provided by the pressure sensor and the corresponding signal provided by the weapon movement sensor;
• and
• a housing that includes the pressure sensor, the weapon movement sensor, the at least one processor, and the memory,
• wherein the housing is configured to mount to an accessory rail of the firearm
• the housing further includes a flashlight or a laser, and
• the computer instructions are configured to cause the at least one processor to operate the flashlight or the laser based on an input from the weapon movement sensor that indicates that the firearm is rotated around a bore axis while the firearm is outside of a holster, or that indicates linear acceleration above a pre-configured threshold along one of more axes of the firearm while the firearm is outside of the holster.

A method comprising:

• obtaining a signal provided by a pressure sensor configured to sense pressure generated from a discharge of a firearm;
• obtaining a signal provided by a weapon movement sensor configured to sense at least one movement of the firearm;
• obtaining a data boundary that is a standard deviation multiple above and below an average of pressure of pressure data;
• determining an event of the firearm, with one or more of at least one processor, based on the signal provided by the pressure sensor and the signal provided by the weapon movement sensor,
• wherein the determining comprises determining the event of the firearm based on an evaluation of a pressure or change in pressure, as sensed by the pressure sensor, with the data boundary, the event determined as a first event, a second event, or a third event based on whether a maximum of the pressure or change in pressure is above, within, or below the data boundary, respectively.

• determine the event of the firearm based on an evaluation of a pressure or change in pressure, as sensed by the pressure sensor, with a predetermined pressure or change in pressure, an evaluation of a velocity or acceleration, as sensed by the weapon movement sensor, with a predetermined velocity or acceleration, and a rise time of the pressure or change in pressure or a rise time of the velocity or acceleration;
• determine the event of the firearm as being a first event based on the rise time being a first time;
• and
• determine the event of the firearm as being a second event, different from the first event, based on the rise time being a second time, different from the first time.
