A safety system for an object comprising a transmitter that comprises a microcontroller to generate an identification signal having a given frequency and a resonant circuit to amplify said signal. The transmitter is suitable to be placed in the vicinity of the body of a person to capacitively couple said identification signal to it. The safety system also comprises a receiver suitable to be capacitively coupled to said body in order to receive said first identification signal and to recognize based on said identification signal if a user is an authorized user. The safety system comprises means to estimate the actual resonant frequency of said resonant circuit when the circuit is amplifying said signal and the microcontroller is adapted to choose as frequency for the identification signal the closest frequency to the estimated actual resonant circuit it can generate so that the amplification of the identification signal is maximized.

The invention relates to a device for securing a gun with a safety catch, the device comprising: a safety body designed to make contact with a sear of the safety catch, and an actuator element that can move between a first position and a second position, wherein the actuator element and the safety body are designed to allow the device to be configured between at least: a firing state in which the actuator element is in the first position, causing the sear to slide along the safety body; and a safety state in which the actuator element is in the second position, preventing the sear from sliding along the safety body. The invention also relates to a case of the firing mechanism and a gun that comprise the device. The invention further relates to a method for securing a gun by means of a safety catch of the gun and a device for securing a gun.

The examples relate to a system for managing authorisations for the personal use of a weapon, which comprises a receiver module coupled to the weapon and a transmitter module configured to be carried by a user close to the body. The transmitter module is located close to the ground and is configured to transmit a signal that represents at least identification code data associated with the user, by means of a path of the signal through the user's body. The receiver module is configured to receive the signal and activate a security system of the weapon to allow the user to use the weapon according to the signal received.
The invention relates to a weapon safety system with a target (100) and a weapon (200), the weapon having an automatic lock (210). Each target (100) is associated with an emitter (300) which transmits an authorisation signal that encodes an identifier (330). Said encoded identifier (330) can release the automatic lock (210) when received by a receiver (400) which is connected to the weapon (200). In order to restrict the positions and orientations from which the weapon (200) can fire to the surroundings of the intended targets (100), firing is allowed and the automatic lock (210) is released when the following conditions are met: - the authorisation signal is received by the receiver, which means that the receiver is inside a first authorisation area generated by a first opening (380) in the emitter (300); - a measured optical power is above a predefined threshold; and - the encoded identifier (330) is validated.
