A vehicle with suspension-controlled motion resistance members is provided. The vehicle includes a body and a chassis coupled to a base of the body. The vehicle further includes a motion resistance member that is coupled to a base surface of the chassis, a wheel assembly coupled to the chassis, and a suspension unit coupled to the wheel assembly and the chassis. In an actuated state, the suspension unit is configured to move the chassis in a first direction until at least a portion of the motion resistance member contacts a ground below the base surface of the chassis.

A rapid deceleration mechanism for a vehicle is provided herein. The rapid deceleration mechanism includes a cutting mechanism configured to be coupled to a body of the vehicle, e.g., via a tether. An actuating mechanism is configured to selectively actuate (e.g., release or propel) the cutting mechanism towards a road surface on which the vehicle is driving to cause the cutting mechanism to cut a channel in the road surface. The channel defines a bollard area in the road surface. At least a portion of the cutting mechanism is disposed at least partially within the channel, against the bollard area, to anchor the body of the vehicle relative to the road surface.

Locking systems and method of manufacturing the same are provided. A locking system for fall protection includes a braking lever. The braking includes a shock absorber. The shock absorber includes a plurality of coils. The shock absorber also includes a plurality of breakaway interfaces coupling the plurality of coils together. Each of the plurality of breakaway interfaces are configured to decouple two of the plurality of coils at a different force. At least one of the breakaway interfaces defines at least one deformable finger defined on one of the plurality of coils of the shock absorber interfacing with another coil of the shock absorber.

A locking system is provided for fall protection. The locking system includes a housing. The housing defines a guide path through which the housing is slideably attached to a guide member. The locking system also includes a braking lever having a braking surface and an attachment end. The braking lever is configured to rotate so as to allow a braking surface to engage the guide member. The locking system further include a locking lever that is rotatably coupled to the braking lever. The locking lever is rotatable such that it rotates from an unlocked position to a locked position. In the unlocked position an activation end of the locking lever is positioned in a first location that is proximate to the attachment end and in the locked position the activation end is positioned in a second position distant to the attachment end.

A moving device includes an elastic tube, a sectional shape of which is elastically deformable according to an internal pressure given by fluid, a slider unit capable of moving forward and backward in a longitudinal direction of the elastic tube according to a change in the sectional shape of the elastic tube, a brake provided in the slider unit and configured to be deformed in a direction perpendicular to the longitudinal direction of the elastic tube to be capable of coming into sliding contact with a target object, and a fluid adjusting section configured to supply air to or discharge air from the elastic tube respectively via first and second fluid supply pipes that respectively communicate with insides on a distal end side and a proximal end side of the elastic tube.

The zip line rail system can be connected to a challenge course, a zip line, a zip track system, or any combination thereof. The zip line rail system of the present invention can have two rails that a member slide's two wheels rollably engage with, and the zip line rail system can be configured in any of a variety of directions.

Described herein is a device comprising members in a kinematic relationship. The kinematic relationship is at least partially governed by at least one magnetic flux interaction that, in effect, may provide a tunable resistance to movement, changing the rate of relative movement between the members. In one embodiment, the device comprises a first member in a kinematic relationship with at least one further member to form a system. The system moves within a limited range of motion and the system interacts when an external energizing force is imposed on the system causing the members to respond due to their kinematic and dynamic characteristics and thereby creating relative motion between the members. The trigger member is coupled to the at least the first member and moves in response to a pre-determined system movement. When the trigger member moves, the trigger member imposes a braking action on the system or a member or members thereof. The speed and/or intensity of the braking action imposed by the trigger member on the system or a member or members thereof is controlled by the trigger member rate of movement. This rate of movement is in turn governed by a magnetic flux interaction between the trigger member and the at least one first member causing formation of a magnetically induced eddy current force between the parts.

A load lowering descent controller having a fixed cylindrical body or capstan about which a rope or cable is turned. The descent controller allows for lowering of the load at a controlled rate by adjusting the amount of friction between the controller and the rope or cable as a function of rope or cable turning and relative contact with rope or cable engagement surfaces in the controller. The fixed cylindrical body or capstan is surrounded by a vented sleeve to prevent the rope from becoming heated and to prevent the user from being injured.
