Wheelchair system and method of use
A wheelchair system may include vehicles including docking systems for a wheelchair.

6. The wheelchair system of claim 3 , wherein the distance is adjustable.
7. The wheelchair system of claim 1 , wherein the dock controller is configured to send a signal to the actuator of the docking system to reduce the height of the coupler mechanism after the coupler mechanism of the docking system is engaged with the coupling device of the wheelchair, to further secure the wheelchair to the docking system.
8. The wheelchair system of claim 1 further comprising a computing device and a data processing system configured to communicate with the dock controller and the computing device, wherein:
the computing device is configured to send a signal to the data processing system indicating that the docking system has been selected; and
the dock controller is configured to send a signal to the data processing system indicating that the docking system is not selectable when the coupler mechanism of the docking system is engaged with the coupling device of the wheelchair.
9. The wheelchair system of claim 8 , wherein after the coupling device of the wheelchair is disengaged from the coupler mechanism of the docking system, the dock controller is configured to send a signal to the data processing system indicating that the docking system is selectable.
10. The wheelchair system of claim 1 further comprising the vehicle, wherein the docking system is one of a plurality of docking systems coupled to the vehicle;
wherein the vehicle is one of a plurality of vehicles each having a plurality of docking systems; and
wherein a computing device is configured to display the selectability of each of the plurality of docking systems of each of the pluralities of vehicles.
11. The wheelchair system of claim 1 further comprising a sensor configured to detect the distance.
12. The wheelchair system of claim 1 , wherein the dock controller is further configured (a) to continuously receive the signal indicative of a clearance distance of the coupling device as the wheelchair approaches the securement location, and (b) continuously send the signal to the actuator of the docking system to adjust the height of the coupler mechanism based on the signal indicative of the clearance distance of the coupling device prior to the wheelchair being disposed in a securement location whereby the coupler mechanism may engage with the coupling device simultaneously with the wheelchair entering the securement location.
13. A method of operation for a wheelchair system comprising:
receiving, with a dock controller that is operatively coupled to a docking system for a wheelchair, a signal indicative of a distance between a coupling device on the wheelchair and a floor of a securement location; and
adjusting a height of a coupler mechanism on the docking system prior to the wheelchair being disposed in the securement location based on the signal indicative of the distance whereby the coupler mechanism may engage with the coupling device simultaneously with the wheelchair entering the securement location.
14. The method of claim 13 , further comprising:
operatively connecting the dock controller with a wheelchair controller of the wheelchair via a wireless communication network, whereby the dock controller receives the signal indicative of the distance from the wheelchair controller the wheelchair controller.
15. The method of claim 14 , further comprising:
sending a signal to a computing device to request authorization for connecting the dock controller with the wheelchair controller via the wireless communication network, prior to operatively connecting the dock controller with the wheelchair controller via the wireless communication network.
16. The method of claim 13 , further comprising:
selecting the docking system with a computing device;
sending a signal to a data processing system to indicate that the docking system was selected; and
indicating that the docking system is no longer selectable.
17. The method of claim 13 , wherein the wheelchair includes a set of wheels configured to rest on the floor, a bottom surface supported above the floor by the set of wheels, and the coupling device positioned on the bottom surface of the wheelchair.
18. The method of claim 17 , further comprising:
securing the wheelchair to the docking system;
wherein securing the wheelchair to the docking system includes:
engaging the coupler mechanism of the docking system with the coupling device of the wheelchair; and
reducing the height of the coupler mechanism of the docking system, after the coupler mechanism of the docking system is engaged with the coupling device of the wheelchair, to reduce the distance.
19. The method of claim 18 , further comprising:
adjusting the distance.
20. The method of claim 17 , further comprising:
securing the wheelchair to the docking system;
operatively connecting the dock controller with a wheelchair controller via a wireless communication network; and
sending signals indicative of the distance through a secure communication channel, continuously, while the wheelchair controller is operatively connected to the dock controller.
21. The method of claim 13 , further comprising:
securing the wheelchair to the docking system;
disengaging the wheelchair and the docking system; and
