A multi-diameter clamp for clamping on tires of different sizes is provided. The multi-diameter clamp comprises at least one clamping unit, at least one actuator, and at least one sensing unit. The at least one clamping unit further includes at least one movable member and a fixed member. Wherein the at least one movable member moves within a tire housing space having a starting position and a clamping position. The tire housing space locates between the movable member and the fixed member for clamping on a tire. The at least one actuator connects to the at least one movable member, and enables the at least one moveable member to move between the starting position and the clamping position. The at least a sensing unit obtains a diameter size of the tire, and based on the diameter size, actuates the at least one actuator corresponding to the diameter size.

A rail car hand brake locking system utilizes a connection member and a securing body. The connection member has an aperture near each distal end. The securing body has a head end capable of securing around a portion of an actuating wheel of the hand brake and a connection end capable of securing to the connection member, which is then affixed to the hand brake housing. The system prevents unauthorized usage of the hand brake.

A vehicle arresting device and method is described that includes the use of flexible substrate that is launched into the path of a fleeing vehicle. The arresting device may be remotely controlled in order to provide more safety to the user. The net like substrate is configured to wrap around at least one tire of the fleeing vehicle and bring the vehicle to a stop.

A vehicle arresting device and method provides a flexible net that is designed to be launched into the path of a target vehicle. The net may provide upwardly pointing spikes that are designed to embed into the tire of the target vehicle thereby causing the flexible net to wrap around the tires of the target vehicle which cause the tires to stop rotating and brings the target vehicle to a safe stop. The arresting device may be remotely controlled by the user.

An anti-theft vehicle brake including a lockable restraining hub coupled to a wheel. The lock's default state being engaged and preventing rotation of the wheel. The lock including a solenoid bolt controlled through the communication of authenticating information sent from a transmitter and recognized by a receiver, triggering the disengagement of the bolt from the restraining hub allowing rotation of the wheel.

A jack lock has a hinged jack enclosure that encompasses a trailer jack. In a first restraining position the jack enclosure prevents a trailer jack from retracting to an transport position. In a second releasing position the jack lock may be easily and quickly removed from the jack. To further deter theft, a tongue arm is unitarily fabricated with and extends from the jack enclosure. The tongue arm runs under a trailer ball receiver, and terminates with a hitch stop that wraps around the ball receiver to block a land vehicle from accessing the trailer coupler. A lock selectively holds the jack enclosure closed to prevent the trailer jack from retracting, but when unlocked permits the jack enclosure to be removed from the trailer jack. Removal of the jack enclosure will also remove the hitch stop from blocking the ball receiver. A lock enclosure prevents access to the locking mechanisms.

A vehicle locking boot includes a horizontal support arm and a first vertical support arm extending. from the horizontal support arm. The first vertical support arm includes a front engagement protrusion extending therefrom. A receiving sleeve extends from the horizontal support arm at a base of the first vertical support arm, A horizontal extension portion is coupled to the horizontal support arm A second vertical support arm, extends from the horizontal extension portion along a direction orthogonal to the upper surface of the horizontal support arm. The second vertical support arm includes a rear engagement protrusion extending therefrom. The front engagement protrusion faces the rear engagement protrusion. A keypad is disposed on the first engagement portion. The keypad is configured to lock and unlock the horizontal extension portion. A lug nut blocking plate is coupled to the first vertical support arm above the first engagement protrusion.

A wheel lock having an L-shaped member and a hub mount. When coupled to a wheel of a trailer, the rotation of the wheel forces the L-shaped member into the ground, or into the underside of the trailer, thus immobilizing the wheel from rotating. Additionally, a puck lock, and a locking member having a lock guard, are utilized to ensure that the lock is not tampered with. Furthermore, a shield is incorporated to prevent an unauthorized user from removing the fasteners that secure the wheel lock to the wheel of the trailer.

A method is provided that includes receiving an indication of unauthorized use of a vehicle that includes a motor to generate torques that are applied to one or more drive wheels to cause the one or more drive wheels to rotate and propel the vehicle. The method includes receiving a sensed input from the one or more sensors. The method includes, based on the indication of the unauthorized use of the vehicle, commanding the motor to generate a torque that is opposite the indicated rotational motion of the one or more drive wheels, with the generated torque applied to the one or more drive wheels to counteract the indicated rotational motion of the one or more drive wheels.
