A portion of ankle movement can be harnessed into stored energy that can be released for various purposes, such as to assist in movement or to charge a battery. This harnessing can be achieved in various manners. In one example manner, an offset pulley component can transfer ankle movement to a generator in a shoe insole. In another example manner, a slider can cause a brace arch to match an ankle arch such that the movement is appropriately harnessed.

Braking systems for railway cars are provided. A braking system defines a longitudinal axis, and includes a first brake assembly, a second brake assembly, and an actuator operable to generate a linear force, the actuator disposed proximate the second brake assembly. The braking system further includes a movable rod and a fixed rod extending between the first brake assembly and the second brake assembly. In some embodiments, the braking system further includes a dead lever and a slack adjuster disposed proximate the first brake assembly, the slack adjuster connected to the first brake assembly and the dead lever and operable to adjust a distance along the longitudinal axis between a reference point of the first brake assembly and a pivot point of the dead lever.

A band brake actuator is for actuating a band brake on a planetary gearset. The band brake actuator comprises a actuator shaft; an output finger; and a linkage assembly. The linkage assembly connects the actuator shaft to the output finger such that rotation of the actuator shaft in a first rotation direction causes the output finger to engage the band brake on the planetary gearset, and such that rotation of the actuator shaft in an opposite, second rotation direction causes the output finger to disengage the band brake from the planetary gearset. Engagement of the band brake and the planetary gearset shifts the planetary gearset into one of a forward and a reverse gear and wherein disengagement of the band brake and the planetary gearset shifts the planetary gearset into a neutral gear.

An adjustable brake controller of an elevator brake comprises a DC bus; first terminals for connecting the brake controller to a first magnetizing coil; second terminals for connecting the brake controller to a second magnetizing coil; a first controllable power switch coupled between the first terminals and the DC bus, the first controllable power switch being configured to supply electric power from the DC bus to the first magnetic coil responsive to a first control signal; a second controllable power switch coupled between the second terminals and the DC bus, the second controllable power switch being configured to supply electric power from the DC bus to the second magnetizing coil responsive to a second control signal; and a controller configured to generate the first and the second control signals for controlling the first and second power switches, respectively. The controller has: a brake open mode, wherein the first and second control signals have a same specified pattern, and a brake holding mode wherein the first and second control signals have a different specified pattern.
