The present invention relates to a vehicle braking arrangement for a vehicle with wheels contacting the ground during normal running. The vehicle braking arrangement includes an emergency brake control unit, a first emergency braking system including non-reversible braking means arranged to operate independently of the vehicle wheels, at least one acceleration detector, and a wheel brake anti-locking system. The emergency brake control unit is arranged to input acceleration data (a) when the wheel brake anti-locking system is active, and to calculate the coefficient of friction () between the wheels and the ground. The emergency brake control unit is arranged to determine if the first emergency braking system should be activated in dependence of a first plurality of parameters, where one of these parameters is the coefficient of friction ().

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.

A vehicle deceleration system for stopping a vehicle that includes of a set of sensors, a controller, force applicators, and a friction applicator. The first sensor reads the ambient air temperature, the second sensor reads the vehicle speed, and a third sensor indicates if antilock brake system is operational. The controller calculates the distance between the front bumper and any surrounding objects to adjust the stopping force accordingly. The controller monitors the three sensors and a processor checks for predetermined given conditions. If all checks are met, the controller activates the force applicators. When the force applicators extend, they rotate a friction applicator into the road surface until the vehicle comes to a complete stop.

A movable standing base for parasols, display boards, flagpoles and the like comprises a weight part having, firmly attached at the bottom side thereof, at least three, preferably four steering rollers, and it further comprises attachment elements for a parasol, for a display board, for a flagpole or for any other objects to be set up, and a plurality of preferably four lowerable blocking feet. In order to improve ease of handling without loss of stability, the blocking feet are connected to each other in the edge region of the weight part by two bridge girders arranged opposite to each other and a middle yoke and are anchored to the weight part in a substantially parallelogram shaped lowerable manner by two pivot levers. A tensioning lever is disposed resting on the middle yoke, and a pressure element leads to a blocking pedal at the upper side of the standing base.

A foot pedal assembly and method of moving a wheel assembly from a stowed configuration to a deployed configuration is provided. The foot pedal assembly can be moved to a locked configuration, thereby securing the wheel assembly in a deployed configuration, by allowing a foot pedal of the foot pedal assembly to move away from a second position after moving the foot pedal from a first position to the second position. When in the locked configuration, the foot pedal assembly can be moved to an unlocked configuration by moving the foot pedal assembly back to the second position, thereby allowing the foot pedal assembly and the wheel assembly to move towards the first configuration and the stowed configuration, respectively. A pin extending from a cam assembly into a raceway of a raceway body travels through the raceway as the foot pedal assembly is moved between configurations.

According to one aspect, an apparatus for reducing the speed or acceleration of motion of a skateboard and its user is disclosed. According to one embodiment, the apparatus includes one or more friction elements that are removably affixed to a substantially flat resilient member at a location near the first end of the resilient member typically proximate to the rear wheel mounting truck; the resilient member is then affixed by fasteners upon its opposite and second end to the underneath face of the platform of the skateboard, typically proximate to or forward of the center of the platform. The apparatus also includes a substantially rigid linkage that penetrates the skateboard platform and is affixed to near the first end of the resilient member for the purpose of interfacing the first end of the resilient member selectively to one foot of a user of the skateboard, such that when the user desires to reduce the speed or acceleration of the skateboard the user applies to the linkage a force substantially normal to the skateboard platform and therefore the resilient member. The force applied to the resilient member causes the friction element or elements to contact the riding surface, creating by the contact of the friction element or elements with the riding surface a frictional force that is transmitted to the skateboard platform via the fixation of the second end of the resilient member to the skateboard, opposingly counteracting the velocity or acceleration of the skateboard and user, thereby slowing the motion. The frictional force is modulated by the variable force applied to the apparatus by the user.
