  • Patent number: 10806649
    Abstract: An enhanced mobility wheelchair with semi-autonomous control logic includes criteria for selecting level, stair, and slope modes. Each mode progresses through criteria-invoked phases as the wheelchair travels. Each axis performs an assigned duty for each mode and phase combination to seek a defined target. Control logic invokes stair mode from the level mode when steps are sensed. Criteria restricts negotiating obstacle angles and heights encountered beyond capability and permits reversed travel to exit obstacle. Front and rear support systems include the ability to sense both forward and backward facing steps by adding distance sensors, sensing linkage and rotary sensors. Legrest adjustment raises the feet for forward step climbing and shortens the wheelchair length for tight turns. Steep down slope and steep up slope modes are invoked from a small angle slope mode. Absolute measurement of spider rotation and spider cam engagement does not require adjustment.

  • Patent number: 10800452
    Abstract: A power steering apparatus assists steering of a vehicle by conferring torque generated by an electric motor to a steering mechanism. The apparatus includes a steering column with linked upper and lower steering shafts. An angle sensor (AS) includes a gear and magnet to measure the steering shaft angle. A torque sensor (TS) measures the relative shift angle between the upper and lower steering shaft and includes a multi-pole ring magnet and a magnetic flux conductor. The TS and AS are arranged such that the AS magnet influences the TS measurement creating a steering shaft angle depending error signal. The steering mechanism is arranged such that a zero crossing of an envelope curve of the error signal is given for the neutral position of the steering apparatus or a range of the steering position in which the steering angle is less than a threshold angle limit.

  • Patent number: 10786406
    Abstract: Powered patient support apparatuses—such as beds, cots, stretchers, or the like—include a plurality of user controls that allow a caregiver to control the steering and/or driving of one or more powered wheels from multiple different locations around the patient support apparatus (e.g. head end, foot end, and/or the sides). The control is carried out by force sensors that detect both an orientation of the applied forces and a magnitude of the applied forces. Translational and/or rotational movement is effectuated, depending upon the magnitude and direction of the forces, as well as the physical location of the applied force relative to a reference point on the support apparatus, such as the center. One or more object sensors may also be included in the support apparatus to assist in steering and/or navigating.
