A rail system comprises: a guide rail; a plurality of stationary electromagnets mounted in the guide rail; and a carriage having a plurality of wheels configured to travel along the guide rail. The wheels are magnets. Movement of the carriage along the guide rail is brought about by a fluctuating magnetic field generated by the stationary electromagnets acting on the wheels.

Disclosed is an arresting system for arresting a swivel motion between two swivel-mounted elements, including a brake rod connected to the first element, an arresting device on the second element with a housing, through which the brake rod extends, in which case the arresting device has a drive and at least one brake-shoe element that can be moved via the drive relative to the brake rod. The brake-shoe element is inside the housing and engageable with the brake rod upon exertion of a braking force. Included are a sensor, and an electronic device controlling braking force exerted by the brake-shoe element on the brake rod depending on the signals from the sensor. The drive is an electric motor driving in rotation an actuation element that, to produce the relative motion between the brake-shoe element and the brake rod, has an actuation cam acting on the brake-shoe element.

An example firearm receptacle includes a mounting structure, a firearm holder, and a door stopper. The mounting structure is configured to be fixably mounted to one of a wall or a door. The door stopper is configured to transition between a deployed position and a stowed position. In the example embodiment, the door stopper is configured to impede the opening of the door when the door stopper is in the deployed position and to allow the opening of the door when the door stopper is in the stowed position. The door stopper is additionally configured to prevent the door stopper from transitioning to the stowed position when a firearm is disposed in the firearm holder.
