a controller for controlling the functionality of the device including illumination of the illuminator, in response to activation of the firearm trigger; an actuator, being electrically connected to the controller, for activating the controller whenever being struck by the firearm striker and a power source for providing DC power to the controller and illuminator. ## Claims ### Claim 1 A multifunction dry fire training device to be inserted into the chamber of a firearm, comprising: an illuminator for emitting, upon receiving a command from a controller, a first beam of visible light and a second beam of invisible light from the barrel of said firearm, said first and second beams of light being centrally aligned with the barrel; a controller for controlling the functionality of the device including illumination of said illuminator, in response to activating the trigger of said firearm; an actuator, being electrically connected to said controller, for activating said controller; and a power source for providing DC power to said controller and to said illuminator. ### Claim 2 (depends on 1) A device according to claim 1, in which the first beam of light has a predominant wavelength of approximately 635 nm and the second beam of light has a predominant wavelength of approximately 780 nm. ### Claim 3 (depends on 1) A device according to claim 1, further comprising a collimator for focusing the emitted beams on a target. ### Claim 4 (depends on 1) A device according to claim 1, in which the illuminator includes a light emitting diode for emitting at least one wavelength of light or a laser diode for emitting coherent stimulated electromagnetic radiation. ### Claim 5 (depends on 1) A device according to claim 1, comprising: a hollow body consisting of a first casing that includes a first securing mechanism for attaching and securing said first casing to a second casing; a second casing to which an illuminator is attached, said second casing being electrically connected to said first casing; an insulating sleeve containing said power supply, for readily preventing contact of the power supply with said first or second casing; and two spring-like biases situated at opposite sides of said power supply and on the long central axis of said dry fire training system, for allowing said power supply to move the striker strikes. ### Claim 6 (depends on 1) A device according to claim 1, in which the actuator consists of: a striking pad being capable of sustaining a plurality of strikes by the striker, without being pierced; a conductive material for activating the control circuit; an energy absorbing material for dampening strikes; and a conductive end pin located within a bell shaped absorbent material, to contact the face of the control circuit. ### Claim 7 (depends on 1) A device according to claim 1, in which the actuator is constructed from at least one crystalline formation, for converting the applied mechanical stress to electric current or to changes in conductivity, distinguishable by the control circuit. ### Claim 8 (depends on 1) A device according to claim 1, in which the controller comprises a microcontroller, for allowing exact control of the illumination time and the delay time. ### Claim 9 (depends on 8) A device according to claim 8, in which the illumination time is 1-15 mSec. ### Claim 10 (depends on 1) A device according to claim 1, in which the controller is programmed to: turn on the light with the first shot and turn off the light with the second shot, to align the sights; and implement a delay every several “shots,” to simulate a magazine change. ### Claim 11 (depends on 1) A device according to claim 1, in which the emitted light carries digitally coded information that modulates the illumination of said light. ### Claim 12 (depends on 1) A device according to claim 1, in which the illuminator emits invisible wavelength to carry coded information, in addition to visible light. ### Claim 13 (depends on 1) A device according to claim 1, in which the controller records the device history data within a memory. ### Claim 14 (depends on 1) A device according to claim 1, in which a set of programs is set to run and determine the functionality and different operation modes of said device. ### Claim 15 (depends on 1) A device according to claim 1, in which the actuator operates as a toggle switch for initiating changes in the operation mode. ### Claim 16 (depends on 1) A device according to claim 1, further comprising a communication port, for communicating with the controller and the memory, for retrieving data or setting functionality programs. ### Claim 17 (depends on 1) A device according to claim 1, further comprising a collimator attached to, or integrally formed with the illuminator, for focusing light and/or electromagnetic radiation emitted from said illuminator. ### Claim 18 (depends on 1) A device according to claim 1, in which the control circuit is biased using a standing flat spring. ### Claim 19 (depends on 1) A device according to claim 1, further comprising a pneumatic element for allowing discharge of a dry fire training device. ### Claim 20 (depends on 1) A device according to claim 1, further comprising an attachment element for securing said device to different barrel 33 lengths using a locking mechanism. ### Claim 21 (depends on 1) A device according to claim 1, further comprising a retaining pipe assembly. ### Claim 22 (depends on 1) A device according to claim 1, consisting of a front 11 part and a rear 4 part, being detachable from each other, wherein different rear 4 parts include different functionalities. ### Claim 23 (depends on 1) A device according to claim 1, further comprising a hollow tube connected to the front end of the laser bullet by threading, to allow connection of modular extensions. ### Claim 24 (depends on 1) A device according to claim 1, in which one or more O-rings are placed along the hollow tube, to prevent contact between the barrel 33 and said hollow tube, while installing and using said tube.
