Abstract: In one aspect, a system for rephasing fluid-driven actuators includes a plurality of fluid-driven actuators fluidly coupled together in series. A controller is configured to monitor a position differential existing between current positions of rods of the actuators relative to a differential threshold based on sensor measurements. The actuators are out-of-phase when the monitored differential exceeds the threshold. The controller is also configured to initiate a flow of fluid to the actuators to rephase the actuators when the monitored differential exceeds the threshold. The controller is further be configured to continue to monitor the differential following initiation of the flow of fluid to the actuators. Additionally, the controller is configured to implement a control action associated with terminating the rephasing of the actuators when the monitored differential remains constant after a first time period has elapsed following initiation of the flow of fluid.

Abstract: A para-alpine ski, typically a dual-runner sit-ski, has a seat and undercarriage that a user/skier can—under no force(s) save his/her own—cause to raise to a height sufficient so as to permit boarding—totally unassisted if needs be—of the user-skier and his/her entire para-alpine ski onto a moving carry chair of a standard ski-slope chair lift. Upon disembarking the ski slope chair lift the user-skier can lower his/her seat for skiing, again without assistance. When the same sit-ski is used to ferry a total invalid then a trained instructor or guide who normally stands at, and steers from, the back of the sit-ski can stand alongside the sit-ski and its occupant at the point of loading the chair lift, and can trigger the sit-ski seat and its occupant to rise, again permitting that the chair of a standard ski-slope chair lift may be adroitly mounted.

Abstract: A single wheelchair selectively mounts at times each of a plurality of different wheelchair seats, one at a time, so as to customize seating upon and within the wheelchair as then best suits the preference of the user-occupant of the wheelchair. Seats support both formal and sport uses of the wheelchair. A detachable sport seat has in particular a deep contour seat base hinged to a deep contour seat back, providing thus substantial lateral support to a seated occupant of the wheelchair.

Abstract: Method and system for managing multiple information sources to create a single virtual information source. The method and system include the ability to virtually remove redundant information to avoid duplication of records that, while appearing to refer to possibly different entities, refer to the same entity. Such a removal process may be achieved without actually removing an entity from its original data source.
