A method and system for collision avoidance that goes beyond automatic steering and braking. A trained artificial intelligence (AI)/machine learning (ML) system is used to detect an impending impact event that exceeds a predetermined severity threshold based on received sensor and vehicle operational data. Upon detecting such an impending impact event, vehicle systems are deployed to avoid or lessen the severity of the impending impact event. These vehicle systems include automatic steering and braking, and automatic tire flattening and vehicle anchor deployment which are intended to stop or slow the vehicle before impact.

Apparatus for covering product containers loaded in a cargo container is disclosed. The apparatus includes an automated cord reel including a spool and a motor configured to drive the spool. The spool when activated reels in a cord attached to a cargo blanket to spread the cargo blanket over product containers in the cargo container in a smooth motion and/or relatively constant speed to prevent snagging on the product containers. The automated cord reel may be configured as a mobile unit with wheels. A brake system may be provided to prevent movement of the automated cord reel during operation. The automated cord reel may have a battery to provide electric power to the motor. A magnetic floor brake may be configured to hold a cart body in a selected position.

The disclosure relates to an air treatment device, including: a device body, configured for air treatment; wheels, arranged on the device body and configured to drive the device body to move; and a parking mechanism, movably connected to the device body, where the parking mechanism can move relative to the device body to be in contact with or separated from the ground, such that the air treatment device is in a parking state or a free state.

Devices, systems, and methods are described that provide an braking system for a motor vehicle. The braking system extends a friction device from beneath the vehicle to contact the driving surface. Orientation of the friction device and forces applied to the braking device can be adjusted during the braking procedure.

In some braking devices forces generated during braking are directed to a load bearing arm and supporting frame, thereby minimizing damage to actuating devices. The friction device can be retracted after use, permitting normal vehicle operation.

A vehicle emergency braking apparatus performing emergency braking without slipping in high- and low-velocity states to inhibit accidents or reduce damage. A braking body has one end axially coupled to a lower side of the vehicle and the other end provided with a braking blade to generate braking force when in contact with the ground. An electric winch is provided on the lower portion of the vehicle to be spaced apart from the braking body, and winds or unwinds a main wire connected to the other end of the braking body. A returning member having elastic force toward the vehicle is connected to the other end of the braking body. When the main wire is wound by the electric winch, the other end of the braking body is pushed by force greater than elastic force of the returning member so that the braking blade comes into contact with the ground.

A magnetic track braking device for a rail vehicle includes at least one pressure-medium-actuated actuation cylinder, which has a cylinder housing and an actuation piston movable relative to the cylinder housing, at least one magnet apparatus, which can be lowered into a low position onto a rail by the at least one actuation cylinder to generate, by a magnetic short circuit with the rail, a magnetic attractive force between the rail and the at least one magnet apparatus, and which can be placed, by the actuation cylinder, into a high position raised from the rail and into any intermediate positions between the low position and the high position; at least one high-position detecting apparatus, which generates a high-position signal when the high position is assumed by the at least one magnet apparatus.
