  • Patent number: 10498210
    Abstract: 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.

  • Publication number: 20190211559
    Abstract: Described herein is a coupling device, associated parts and a method of use thereof. In one aspect, a coupling device is described comprising a sleeve with an inner surface that encloses at least part of at least one elongated element to be coupled; and at least one deformation means fitted with interference between, and causing local deformation about, at least part of the inner surface of the sleeve and/or an adjacent outer surface of the at least one elongated element. A deformation means insertion tool, a coupling sleeve, a deformation means, and a method of coupling at least one element are also described. The described coupling device, associated parts and a method of use offer the ability to couple together different elements in a strong and/or ductile manner, coupling being tuneable as needed to suit the preferred application. The coupling described may overcome art issues associated with bulky size of coupling, in particular, radial protrusion.

  • Publication number: 20190173355
    Abstract: Described herein is a device comprising members in a kinematic relationship. The kinematic relationship is at least partially governed by at least one magnetically induced force that introduces a force threshold that, in effect, provides a threshold to part movement and confers a degree of hysteresis, preventing movement until a sufficiently large energizing force is applied. The effect may be further altered by use of an additional magnetically induced force interaction with at least one further member to urge or slow movement once started and/or to prevent movement once a new position is reached.

  • Publication number: 20190145070
    Abstract: Described herein is a longitudinal beam barrier system that comprises a longitudinal beam and a post linked together via a fastener incorporating at least one deformable washer. The link is made in a releasable and tunable manner dependent on an applied force via the at least one deformable washer. Release may be made dependent on both the magnitude and direction of the force so that release may be a result of different release forces in different force angles. The deformable washer may be designed to transfer a longitudinal beam load force from a fastener to a post wall, the washer extending around the fastener and having a first face that bears on the fastener or a part thereof (or forms part of the fastener) and an opposing face that at least partly bears on a part of the post wall or walls.

  • Publication number: 20190020259
    Abstract: Described herein are latching devices where relative speed of movement between members is in part controlled or reduced via eddy current formation and in part controlled or relative motion stopped via a latch arrangement. Various embodiments are described, one being use of a conductive member; at least one magnetic field and a latch member that, prior to latching, moves independently to the at least one conductive member. A kinematic relationship exists between the conductive member and at least one magnetic field that enables the conductive member to move at a different speed relative to the magnetic field on application of an energizing force, thereby inducing an eddy current drag force by relative movement of the conductive member in the magnetic field. The eddy current drag force resulting causes movement of the conductive member causing the conductive member to engage the latch member thereby halting movement between the at least one conductive member and the at least one latch member.

  • Publication number: 20180370484
    Abstract: Variable behaviour control mechanism with a variety of motion characteristics, the mechanism comprising means to measure a plurality of motion characteristics and to activate systems when a threshold of the motion characteristics is reached. The mechanism described is, for example, a vehicle seat belt and the mechanism minimises or prevents unwanted activation of line extension or retraction of the seat belt. A first mechanism is described where activation occurs between at least one primary system and at least one secondary system when a combination of the sensed motion characteristics achieves a threshold. A second mechanism is described where activation occurs between at least one primary system and at least one secondary system when at least one sensed motion characteristic achieves a threshold, the threshold being modified based on at least one further motion characteristic. A method of use of the above mechanisms is also described.
