The present invention relates to an electric wheelchair having a voice recognition drive system comprising: a traveling apparatus main body unit which has a plurality of wheels in a lower end thereof; a seating unit which is installed in an upper end of the traveling apparatus main body unit so as to be able to be lifted; an auxiliary robot leg unit which is able to be inserted into and protrude from the traveling apparatus main body unit, and which includes multi-joint driven by an external force; and a voice recognition drive unit which extracts a preset command from an externally input voice, and which drives the plurality of wheels, lifts the seating unit, and drives the auxiliary robot leg unit.

A method for controlling a powered wheelchair is disclosed. The method may comprise receiving first information from at least one user sensor coupled to a user of the wheelchair, said first information indicating the movement of the user; receiving second information from a reference sensor coupled to the wheelchair, said second information indicating the movement of the wheelchair; using the first information and the second information to prepare at least one instruction to move the wheelchair; and using the at least one instruction to move the wheelchair.

An electrically assisted wheelchair includes a controller that obtains an inclination assist value by correcting the assist value when a road surface is inclined in a left-right direction of the seat, and performs a downhill turning preventing operation of causing the wheelchair body to travel straight by applying right auxiliary power and left auxiliary power corresponding to the inclination assist value. The controller adjusts the right auxiliary power and the left auxiliary power by correcting the inclination assist value based on a hand rim operation of the user to operate at least one of the right hand rim and the left hand rim in the downhill turning preventing operation.

A multifunctional wheelchair contains: a body, a support plate, a lifting seat, and a shampoo basin. The body includes a retractable mounting, a chair back, at least one drive device, and two frames. The two frames have two main wheels, the two frames have two guide wheels, and the two armrests are arranged on a second drive device. A respective armrest has an abutting portion, and the retractable mounting have two racks. The support plate is detachably engaged on the retractable mounting of the body. The lifting seat is removably engaged on the retractable mounting of the body, and the lifting seat includes a saddle on a third drive device which is configured to drive the saddle to lift or descend adjustably. The shampoo basin is detachably connected on the chair back and included a washing chamber.

A personal mobility device includes a control system including a manually operated actuator, a first forward control valve having an inlet in fluid connection with a source of pressurized gas and an outlet in fluid connection with a first forward port of at least a first pneumatic motor, and a first rearward control valve having an inlet in fluid connection with the source of pressurized gas and an outlet in fluid connection with a first rearward port of the first pneumatic motor. Movement of the manually operated actuator controls actuation of the first forward control valve and the first rearward control valve and thereby flow of gas from the source of pressurized gas to the first forward port and the first rearward port.

An apparatus for facilitating user propulsion of a wheelchair having a frame for supporting a user and a pair of rear wheels that rotate about an axis. The apparatus includes a handgrip having an outer surface and an opposite, inner surface such that when a radial force relative to the axis is applied to the outer surface by the user the inner surface is configured to engage a rear wheel in the pair of rear wheels such that the rear wheel can be rotated and the wheelchair propelled. A pair of coupling members configured to couple the handgrip to the frame and hold the handgrip in a neutral position, and the pair of coupling members are further configured to alternately increase in length and become tensioned as the user moves the handgrip away from the neutral position to rotate the wheel.

A standing training mobile device for carrying a patient to perform active-assisted upright locomotion is provided. The standing training mobile device includes a base, a mobile module, a lifting module, a control module, and a support module. The mobile module and the lifting module are disposed on the base. The control module is disposed on the lifting module and is coupled to the mobile module. The control module includes a manipulation platform and two control assemblies disposed on the manipulation platform for use of the patient. The support module includes a support frame, a first support assembly, a second support assembly, and a third support assembly. The first support assembly, the second support assembly, and the third support assembly are slidably disposed on the support frame respectively. The second support assembly is disposed between the first support assembly and the third support assembly.

A mobile chair apparatus is described that comprises a drive assembly that preferably includes one or more moveable foot pedals, and drive wheels which rotate in response to rotation of the foot pedals by the mobile chair occupant, and a steering assembly which comprises two steering wheels and at least one tiller, configured such that forward and backward movement of said tiller will translate into movement of both steering wheels, wherein the drive assembly and the steering assembly concurrently enable the mobile chair occupant to propel and steer the mobile chair apparatus without assistance from another person.

A device including a frame; an actuator attached to the frame and slidaby movable with respect to the frame along a linear axis, and a helical member positioned within the frame and rotatably movable with respect to the frame about a helical axis of the helical member, wherein the helical axis is parallel to the linear axis, wherein the actuator and the helical member are configured to cooperate with one another such that (a) motion of the actuator along the linear axis in a first linear direction causes corresponding rotation of the helical member about the helical axis in a first rotational direction and (b) motion of the actuator along the linear axis in a second linear direction that is opposite the first linear direction causes corresponding rotation of the helical member about the helical axis in a second rotational direction that is opposite the first rotational direction.

A conveyance to carry humans, such as a wheelchair, is described having levers on each side of the wheelchair that are manually moved forward and backward to propel the conveyance. The user is able to shift into forward, reverse or neutral, brake, and change mechanical advantage (gear ratio), all this without removing the user's hands from the drive levers.
