Abstract
A firearm monitoring system according to the present invention senses the position of a user hand or trigger finger on a weapon and generates a warning, notification, status or control signal when the user finger position is proximate the trigger. One embodiment generates and conditions an excitation stimulus (e.g., interrupted by the presence of a trigger actuator), drives a sensor with that stimulus, detects the user finger position through a change in the sensor output, and generates an appropriate signal for a downstream warning or other device (e.g., alarm, radio unit, laser sighting system, etc.). In this embodiment, the sensor may detect the presence of an object or finger penetrating a trigger guard plane. Another embodiment utilizes a set of sensors to detect the placement of a user trigger finger relative to the trigger. In addition, various types of output alarms may be utilized (e.g., visual and audio alarms, etc.).

14. A monitoring system to monitor user handling of a weapon, wherein said weapon is a firearm operated in response to actuation of a trigger and includes a trigger guard with said trigger disposed within the confines of said trigger guard, and wherein said monitoring system indicates placement relative to said trigger of a user body portion for actuating said trigger and comprises:
-
a sensing unit mountable to said weapon proximate said trigger to sense the presence of a user body portion for actuating said trigger in a vicinity of said trigger, wherein said sensing unit is mountable within said trigger guard confines to detect the presence of said user body portion within those confines and includes; an emitter to emit an energy signal across said trigger guard confines toward said trigger, wherein placement of said user body portion within said trigger guard confines interrupts emission of said energy signal; and a detector disposed proximate said trigger to receive and detect said emitted energy signal; a tubular member disposed proximate said trigger and oriented to receive said emitted energy signal from said emitter, wherein said detector is disposed at a proximal end of said tubular member to receive said energy signal through said tubular member; an indicator unit to provide an indication of placement of said user body portion relative to said trigger in response to detection of said user body portion by said sensing unit; and a control unit to generate control signals for said indicator unit in accordance with said sensing of said user body portion by said sensing unit, wherein said control unit processes signals from said detector and detects the presence of said user body portion in response to interruption of said energy signal.
