  • Patent number: 9850974
    Abstract: A nonlinear mechanical element including a buckling column and hard stops. In one embodiment when the nonlinear mechanical element is subjected to an increasing compressive load, the buckling column buckles at a critical load, resulting in reduced stiffness past the critical load. One or more lateral hard stops may be provided adjacent to the buckling column to prevent the buckling deformation from exceeding a certain extent, and axial hard stops may be provided to shift the load path away from the buckling column when a certain amount of compressive displacement has been reached.

  • Patent number: 9827961
    Abstract: A method is provided for detecting a fault condition in a hydraulic brake system of a vehicle having a first hydraulic brake circuit and a second hydraulic brake circuit. A correlation ratio is determined between a measured pressure and the actual vehicle acceleration. A first wheel velocity differential is determined and a second wheel velocity differential is determined. A weighting value is selected in response to determining whether the correlation ratio is within the predetermined range and whether the first wheel velocity differential and the second wheel velocity differential are opposite signs. The selected weighting value is added to a fault counter. A determination is made whether the fault counter is equal to or greater than a predetermined threshold. A fault condition is detected in response to the fault counter greater than or equal to the first predetermined threshold.

  • Patent number: 9663123
    Abstract: A rail brake includes a rigid enclosure which mounts under a crane so as to dispose the base end of the enclosure over and adjacent a rail. A spring carriage is mounted for vertical translation within the enclosure. Springs are mounted between the spring carriage and the top of the enclosure so that the springs are compressed when the spring carriage is elevated. A brake shoe is mounted under the carriage. Actuators are mounted between the spring carriage and the base end of the enclosure. Extension of the actuators compress the springs and elevate the brake shoe from the rail. Retraction allows the springs to drive the brake shoe against the rail. Elevation of the brake shoe aligns a pair of spline joints between the sides of the brake shoe and corresponding channel walls underneath the enclosure. Removable elongate keys provide the locking splines in the pair of spline joints.
