METHODS AND APPARATUSES FOR CONTROLLING A POWERED MOBILITY DEVICE

A powered mobility device comprises two powered wheels, a controller, and a control handle configured to generate control signals in response to being operated by push and pull inputs from a user. The control handle rotates between a first operating position and a second operating position such than an orientation of the control handle is reversed with respect to a forward movement direction of the mobility device. The controller is configured to control the powered wheels of the mobility device to move in the forward movement direction in response the control handle being operated in the forward movement direction and move in a reverse movement direction in response to the control handle being operated in the reverse movement direction in both the first operating position and the second operating position regardless of the reversed orientation of the control handle.

Joystick Chair

Joystick chair is an input device for interaction between the user and computer. It enables the movement of the user in games. The invention is used by placing feet on the platform (3) and sitting or leaning on the seat (23). Command for turning is achieved by rotating the seat (23), either to the left or to the right. Command for forward movement is issued by pulling the left or right controller (36, 41) with fingers, while the command for backward movement is issued by pushing the left or right controller (36, 41) away by palms. Control handles for lateral movement (49, 56) are separated from the forward-back controls that are located on the controllers (36, 41). Other commands are achieved with buttons on the left and right controller and they are accessible with thumbs. The software allows the modifications of all available actions of the invention.

Elevated height wheelchair

Embodiments of the present disclosure include a wheelchair configured to reposition an occupant between a lowered and a raised position. The wheelchair can include a frame, a seat moveable relative to the frame, a drive wheel, and one or more pairs of arm assemblies. The arm assembly includes a wheel configured to move from a first spatial location when the wheel chair is operating on flat, level ground to a second spatial location that is different than the first spatial location. Arm limiters that can selectively engage the arm assembly dependent on the position of the arm assembly and surface conditions of ground and can limit the range of motion of the arm assembly and sometimes other operational aspects of the chair.
