  • Patent number: 12188745
    Abstract: A holster includes a system for providing an audio and/or a visual notification differentiating a lethal weapon from a less lethal weapon when one of these weapons is removed from its holster. The holster includes a sensor for detecting the presence of a weapon therein as well as removal of the weapon. Upon receiving a signal from the sensor indicating drawing of the weapon, a microcontroller actuates a speaker and/or a visual display to indicate the type of weapon which was drawn. Others are made aware of the type of weapon being drawn or which is currently deployed. The wearer of the holster is also made aware of a mistake if the incorrect type of weapon is drawn.
