DETAILED DESCRIPTION OF THE DRAWINGS

[0026] For the purposes of the description herein, a firearm is meant, for example, a pistol, a handgun, a carbine, a rifle, a gun, such as that illustrated in FIG. 1.

[0027] With reference to the model in FIG. 1, the electronic device can be located on the Slide 101 and 102, more specifically on the rear of the slide where commonly a back plate is located on firearms with striker based firing mechanisms 101 and 102.

[0028] With reference to the block diagram in FIG. 2 the electronic device will now be illustrated and described according to the embodiment of the invention.

[0029] The electronic device comprises of a Processing Module 200 responsible for performing calculations and running algorithms on the device.

[0030] The Processing Module 200 comprises of a Microprocessor 210, a Memory 220 operationally coupled to the Microprocessor 210, and a Digital Signal Processor 230 operationally coupled to the Microprocessor 210.

[0031] The Memory 220 consists of both volatile Random Access Memory and non-volatile memory that stores a processing program loaded and executed by the Microprocessor 210. The non-volatile portion of Memory 210 can comprise of, but not limited to, flash based memory, EEPROM, MRAM, FRAM, or other memories that retain information without the application of power. The processing program, an application software program, and data is stored in the non-volatile portion of Memory 210. The non-volatile portion of Memory 210 can also be used to permanently store heuristic information based on the application software program.

[0032] Non-volatile memory is used in order to retain retain information without using energy and results in reduced power consumption when compared to using Random Access Memory.

[0033] The electronic device further comprises of a Detection Module 100.

[0034] The Detection Module 100 can be a Microelectromechanical Systems (MEMS) device such as an accelerometer or accelerometer and gyroscope. The detection module can also consist of a piezoelectric or piezoresistive device that can produce an output signal proportional to the amount of force experienced by the module. The detection module can also consist of a mass spring device that physically deflects and triggers an output signal based on the acceleration experienced.

[0035] The electronic device further comprises of a Display Module 400.

[0036] The Display Module 400 can be of, but not limited to, an electrophoretic display, electrochromic display, polymer dispersed liquid crystal display, transflective liquid crystal display, reflective liquid crystal display, electrowetting display, OLED display, active matrix thin film transistor display.

[0037] The display device can display numeric information representing remaining rounds in the firearm. The display device can also display numeric information representing a cumulative count of shots fired from the firearm.

[0038] The electronic device optionally comprises of a lighting device. The lighting device can be a light emitting diode or a light emitting diode coupled to a light guide structure to distribute light evenly onto the display.

[0039] The application software program contains, but not limited to, the following functions: define multiple operating views and in this embodiment three views are used; wherein the first view will display a count-up starting from zero and where the user can reset the count to zero; wherein the second view will display a countdown from a pre-programmed number where the user can reset the count back to the pre-programmed number and where the user can set the pre-programmed number; wherein the third view will display a count-up that cannot be reset by the user and is intended to keep the lifetime count of the device.

[0040] The electronic device optionally comprises of a power supply.

[0041] FIG. 3 is an example of what the visual representation of the display used on the device. The display can show less digits depending on the view, shown in 101, such as during the countdown mode.

[0042] FIG. 4 is a representation of the electronic device attached to the firearm. 100 shows the device attached to the rear of the firearm which can be viewed by the operator of the firearm.

[0043] A method of detection of the firearm discharge is shown in FIG. 5. In this method, a sensor outputs an electronic signal that is read by the processing module or the digital signal processor depicted in FIG. 1. The firearm discharge detection is based on the magnitude of the signal.

[0044] FIG. 6 depicts another method of detection of a firearm discharge using two signals. A firearm discharge commonly comprises of multiple acceleration forces. The first force occurs when the ammunition begins its exit of of the firearm causing the slide of the firearm to move toward the operator in normal firing conditions. The slide of the firearm will continue to move toward the operator until it reaches the end of its travel along the firearm frame. An acceleration force in the opposite direction and of greater magnitude is generated when the slide reaches the end of its travel. Detecting a signal of relative smaller magnitude followed by a signal of relative larger magnitude can be used to detect for firearm discharge. This method may reduce the amount of false positives for the device.
