    摘要： A patient support apparatus supports a patient and comprises a litter. The litter comprises a patient support deck and extends longitudinally between first and second ends. A base is configured to support the litter and comprises a base lift mechanism configured to move the litter between lifted and lowered base positions. A side ramp is coupled to the patient support deck along the litter between the first and second ends and extends laterally away from the patient support deck to an engagement end. The side ramp is pivotable relative to the litter between first and second positions. In the first position, the side ramp is planar with or angled upwardly to extend above the patient support deck. In the second position, the side ramp is angled downwardly to extend below the patient support deck for contacting the floor surface with the engagement end when in the lowered base position.

    摘要： This disclosure relates to a wheel assembly (1) comprising a wheel, a deformable chamber (6) containing a transition substance (15) comprising jamming particles and an interstitial gas, and an actuator (14) configured to transform the transition substance (15) between a fluid state in which the deformable chamber (6) can deform into a conformal state as the wheel encounters an obstacle during use, and a rigid state by evacuation of the interstitial gas in which the transition substance is rigidified to maintain the deformable chamber (6) in said conformal state to provide increased purchase on said obstacle.

    摘要： The present invention relates to a wheelchair that includes a base frame having robotic legs and a seat assembly. A pair of armrests include at least one control stick and an electronic display for operating the wheelchair. A motor receives power from rechargeable batteries and extends or retracts the robotic legs. The legs have big wheels and small wheels that assists in movement of the wheelchair, including ascending and descending a staircase. The small wheels can be raised or lowered as per requirements automatically by the motor using a sensor or manually using the control stick. The wheelchair can be operated remotely using a handheld remote-control device enabling a caretaker to remotely activate and maneuver the wheelchair. The wheelchair enables individuals who use wheelchairs to remain independent even in traditionally non-accessible spaces and offers a way for disabled, elderly, and sick individuals to retain their independence.
