A collection of diagnostic and troubleshooting information associated with a power driven wheelchair is stored for access by a microcontroller to be displayed to a user to assist in troubleshooting the power driven wheelchair. A log of fault codes transmitted by various fault-detecting mechanisms is compiled. A user may request display of diagnostic information associated with a selected fault code. The operating instructions of a power driven wheelchair may be updated by using portable storage media onto which a latest version of operating instructions is loaded to transfer the updated operating instructions to wheelchair controller memory. The calibration of a power driven wheelchair can be simplified by providing functionality within the wheelchair controller to change calibration parameters or to transfer calibration parameters from portable storage media.

Method and apparatus for setting or modifying programmable parameters in power driven wheelchair

Controller

A power driven wheelchair and a method for operating same are provided. In one embodiment, the power driven wheelchair includes a system controller with a main controller, a storage device, and at least one input device, a motor assembly, and a common bus. The motor assembly may include a drive motor, a local controller, and a sensor sensing a condition associated with the drive motor and in communication with the local controller. In another embodiment, the power driven wheelchair includes the system controller, an actuator assembly, and the common bus. The actuator assembly may include an actuator mechanism, a local controller, and a sensor sensing a condition associated with the actuator mechanism and in communication with the local controller. Multiple embodiments of the method are related to controlling various arrangements of motor assemblies or actuator assemblies.

Power driven wheelchair

Embodiments of a power and signal distribution assembly for a bed having at least one power input port, at least one controller port, and at least one output port are described. The power input port receives a first DC voltage from a power supply and the power supply receiving an AC voltage and converting it to the first DC voltage. The controller port receives the first DC voltage and outputs at least one power control signal having the first DC voltage. The output port receives signals having the first DC voltage. The power and signal distribution assembly has a first location and the power supply has a second location different from the first location. In other embodiments, the power and signal distribution assembly is located on a frame of a bed and the power supply remote therefrom. Still further, one or more additional controller ports may also be provided.
