Abstract: System and method for providing both powered and free swing operation in a powered orthotic exoskeleton joint. The joint comprises a processor controllable ratchet wheel and pawl type clutch, configured to engage or disengage upon receiving force from a servo actuator. When the processor determines that the clutch should be engaged, it directs the powered actuator to couple the pawls to the ratchet wheel, allowing torque to be transferred from the joint's powered motor, through the clutch, to the gearing that subsequently controls the motion of the joint. Conversely, the processor can direct the powered actuator to decouple the pawls from the ratchet wheel. This in turn decouples the ratchet wheel from the motor, thus allowing the remainder of the joint and any associated joint gearing to engage in relatively free swing motion, without any interference from the motor.

Abstract: Composite laminates fabricated from one or more respective laminae of composite material (e.g., fiber-reinforced polymers) may be pre-formed and fully cured, yet configured to be selectively conformable to a desired radius of curvature. To repair a damaged composite structure, a plurality of such composite laminates may be bonded together to form a repair part that may be bolted to or otherwise secured to the damaged composite structure, thereby repairing the structure using repair parts that may match the parent material of the damaged composite structure. Methods of forming said repair parts from a plurality of such composite laminates may provide advantages in costs and lead time, over conventional techniques. Kits may include a plurality of such pre-formed and cured composite laminates that may be stacked and combined together in a plurality of different arrangements to create a customizable repair part for a given damaged composite structure.

Abstract: A method of operating an exoskeleton device includes: receiving sensor information; connecting a clutch system to a pulley system in; determining whether to engage a drive train gear to the clutch system based on the sensor information; engaging the drive train gear through the clutch system when determined to engage the drive train gear; and powering a first motor to drive the drive train gear for controlling a joint or segment of exoskeleton device.

Abstract: The invention describes a display device for displaying information, comprising a display unit 1 with a plurality of columns C and rows R and a display driver 2. Further the invention describes a display driver 2 controlling a display unit 1 with storing means 3 for providing image information to the columns C of a display. The invention relates also to a terminal for mobile communication with a display device, having a display unit 1 and a display driver 2. To achieve a flexible multiplex rate of the display a control device 4 is arranged to switch off a definable number of rows R of the display depending on a state signal which contains the state information of the rows R. By this the multiplex rate is freely programmable, so in a partial mode (N/{overscore (P)}=0) the multiplex rate is reduced and by this the power consumption is reduced. Further it is possible to enable the rows or the groups of rows in a none consecutive order.
