Disclosed herein is a mover including a plurality of wheels, a body, and a friction braking mechanism. The body has a bottom surface. The body is supported by the plurality of wheels with the bottom surface facing a traveling surface, and travels on the traveling surface by turning the plurality of wheels. The friction braking mechanism applies a brake on the body with at least a portion of the bottom surface or at least a portion of a movable body brought into contact with the traveling surface by switching, while the body is traveling, a state of the movable body from a first state into a second state. The second state is a state where the movable body protrudes from the bottom surface to a different height from in the first state.

A method and system enabling a process for preventing a vehicular accident is provided. The method includes continuously monitoring vehicular impact conditions associated with a vehicle in motion. In response, an imminent impact event associated with the vehicle in motion and an external object is detected and a surface of a roadway below the vehicle in motion is scanned by sensors of the vehicle. Results of the scanning indicate that the roadway surface is safe for deployment of a destructive friction based braking mechanism of the vehicle. The destructive friction based braking mechanism is deployed with respect to a first braking force threshold and it is determined if rate of speed decrease exceeds a specified speed decrease threshold.

An emergency braking system for vehicles, having a hydraulic unit assembly, an oil accumulator assembly that connects to the hydraulic unit assembly, and a brake assembly that connects to the oil accumulator assembly. The brake assembly has at least one brake pad that is mounted underneath a vehicle. When deployed, the at least one brake pad makes contact to produce a predetermined friction with a surface the vehicle is moving upon to stop the vehicle. The hydraulic unit assembly has an oil reservoir connected to an electric motor. The oil accumulator assembly has an oil accumulator connected with a conduit to the oil reservoir. The brake assembly has a hydraulic cylinder and an emergency brake pedal that actuates a pedal switch actuator when the emergency brake pedal is pressed with a predetermined force.

A railway vehicle, including an emergency braking device including at least one brake module, wherein each module includes a contact element intended to be in contact with the ground at the moment of braking, and movable between a retracted position and a deployed position in which the contact element is in contact with the ground and is able to slow down the moving railway vehicle by applying a pressure force to the ground, and at least one control unit that is capable of communicating commands to the brake module, wherein the control unit is able to communicate to the brake module the command to deploy the contact element to its deployed position when at least a portion of the vehicle leaves the track on which the vehicle is traveling.

A mobile imaging device includes a base having at least one caster, a first drive mechanism that moves the system in a transport mode and translates an imaging component relative to the base in a scan mode, and a second drive mechanism that extends caster relative to the base to raise the base off the ground in the transport mode, and retracts the caster relative to the base to lower the base to the ground in the scan mode. A caster system for a mobile apparatus includes a base containing a housing and a caster, attached to the base, the caster having a wheel defining a wheel axis and a swivel joint defining a swivel axis and a pivot point defining a pivot axis, wherein the caster pivots on the pivot axis as the caster is retracted into the housing and extended out of the housing.

A method for slowing transfer of a heavy work machine on a sloping base using a separate transportation device equipped with wheels, the work machine including a set of booms having at least one operating cylinder, an auxiliary device, and a brake including a brake surface, the method including the steps of towing the work machine using a transfer vehicle and the transportation device, supporting the work machine at least partly on top of the transportation device such that the crawler chassis is raised off the sloping base, and supporting the auxiliary device on the brake, the brake surface of the brake contacting the sloping base, using the operating cylinder to press the brake surface against the sloping base to create friction to slow transfer speed of the transportation device, and adjusting pressing of the brake surface taking place through the auxiliary device using the operating cylinder.
