Estimating the term…
The present invention relates to a cartridge-in-chamber detection system for firearms which is independent in situations where the user comes into contact with metal parts of the weapon or situations where said contact does not exist, to provide a reliable indication of the presence or absence of the cartridge in the chamber, where the system comprises means to, through a supply voltage, determine the variation of the electrical capacity between two possible states of the system, when there is no cartridge in the chamber and when there is a cartridge in the chamber, making use of at least one electrode, regardless of the grip performed by the user.
A cartridge-in-chamber detection system for firearms which comprises at least one electrical contact which is connected by a sensor circuit to a microprocessor, wherein the at least one electrical contact is in electrical contact with a cartridge when said cartridge is in the chamber, being both elements, cartridge and the at least one electrical contact, and consequently the metal parts of the weapon which are in physical contact with the cartridge, electrically connected, and where the microprocessor, through the sensor circuit, detects the capacitive variation between the situation in which the at least one electrical contact is electrically connected to at least the metal parts of the weapon and the cartridge, and the situation in which the at least one electrical contact is not electrically connected to at least the metal parts of the weapon and the cartridge, thus making it possible to determine the presence or absence of the cartridge in the chamber respectively.
