Abstract: Existing offloading braces rely on a fixed suspension of the user's afflicted ankle joint, thereby offloading it. However, by suspending the ankle joint and replacing its contact with the ground with another device, one of the user's legs is elongated with reference to the other non-injured leg. This can cause issues with the user's non-injured leg over time as the user adjusts their gait to compensate. Further, by suspending the ankle joint, any articulation previously offered by the ankle joint in walking is forfeit. Such offloading braces can yield an unnatural “peg-like” quality to the user's gait. The presently disclosed adjustable ankle joint distraction devices distract a user's ankle joint, while preserving a sensation of contact of the user's foot with the ground and articulation of the user's ankle joint with reference to the ground.

Abstract: The phase of an acquisition clock for a digital oscilloscope is modulated by summing an offset voltage with the output of the phase detector of a phase lock loop. The offset voltage is generated by a digital-to-analog converter which is fed input values by a microprocessor running a number generator routine.

Abstract: The present invention comprises a runt fault detector which detects positive and negative runt faults based only upon the crossings of a high voltage threshold and a low voltage threshold. Specifically, the runt fault detector detects a positive runt fault when an input signal transitions from below to above the low voltage threshold and then back below the low voltage threshold without first transitioning from below to above the high voltage threshold. The runt fault detector also detects a negative runt fault when an input signal transitions from above to below the high voltage threshold and then back above the high voltage threshold without first transitioning from above to below the low voltage threshold. Simultaneous detection of both positive and negative runt faults may also be achieved by the present invention.
