The unit allows individuals to participate in realistic combats through simulations in a range of different indoor and outdoor environments without substantially endangering their personal, and others safety.
The present invention provides an inexpensive and simple laser transmitter unit for simulating live ammunition in weapons, which emits visible bore sighting beam and invisible infrared beam for purpose of bore sighting invisible infrared beam to sights of weapon as explained below.

Referring to Fig.1, a power supply source such as a battery (116) is connected to a regulator (114) for supplying regulated power to a microcontroller (112). A short range RF module (134), a driver (120) and a blank detection circuit enable (132) as shown in Fig.1are connected to the microcontroller (112) configured to control functionality of laser transmitter unit by sending/receiving commands to/from external devices/internal components. The Short range RF module (134) connected to the microcontroller (112) for wireless communication.

A visible bore sighting beam is activated and/or deactivated by sending a command through an umpire gun (not shown), sensed by an IR sensor (122) connected to the microcontroller (112) to drive a driver (120) for sending a pulse to activate and/or deactivate the visual laser (118).

A mode switch (126) is also connected to the microcontroller (112) for enabling the user to select any one of a single mode, an auto mode and a tri-burst mode based on the weapon. The user is provided with an option for selecting any one of modes include, firing of a weapon without blank round ammunition by activating an Laser Trigger Button(LTB) (128) and firing of a weapon with blank round ammunition by activating a blank detection circuit (130).

The LTB (128) is activated for firing the weapon without blank round ammunition. When user activates the LTB (128) connected to the microcontroller (112) then the power booster (110) is enabled by booster enable (106) and power controller (108) which are activated by the microcontroller (112) for boosting the voltage up to required level based on the weapon effective range for driving the laser driver (104) to send pulse for activating the laser (102) for emitting invisible infrared beam. Count of number of times the emission of invisible infrared beam depends on the selected mode by mode switch (126).The booster enable (106) and the power controller (108) are powered by power supply source such as a battery (116).

When the user disconnects the LTB (128) then the microcontroller (112) enables the blank detection circuit (130) by activating the blank detection circuit enable (132) for firing the weapon with blank round ammunition. The power booster (110) is enabled by the booster enable (106) and the power controller (108) which are activated by the microcontroller (112) for boosting the voltage up to required level based on the weapon effective range for driving the laser driver (104) to send pulse for activating the laser (102) for emitting invisible infrared beam. Count of number of times the emission of invisible infrared beam depends on the selected mode by the mode switch (126).

Such laser transmitter unit is detachably coupled to the barrel of a weapon which emits parallel aligned invisible infrared beam and visible bore sighting beam for visibly bore sighting an invisible infrared beam to sights of a weapon by adjusting impinged visible bore sighting beam on that portion of a target in the sights of weapon.
