1. An automatic wheelchair locking system comprising:
- a first touch sensor configured to detect a touch of a first wheel of a wheelchair;
a first lock for the first wheel;
a first motor configured to engage and disengage the first lock;
at least one processor configured to communicate with the first touch sensor and control the first motor; and
a memory having stored thereon instructions that, when executed by the at least one processor, control the at least one processor to;
in response to receiving sensor information from the first touch sensor indicative of a user touching the first wheel while the first lock is engaged, control the first motor to disengage the first lock; and

17. An automatic wheelchair locking system comprising:
-
a touch sensor configured to detect a touch of a wheel of a wheelchair; a motion sensor configured to detect motion of the wheelchair; a lock for the wheel; and a motor configured to; disengage the lock in response to detection signals from the touch sensor indicating that the wheel is being touched while the lock is engaged, and engage the lock in response to detection signals from the touch sensor indicating that the wheel is not being touched and detection signals from the motion sensor indicating that the wheelchair is substantially still while the lock is disengaged. - View Dependent Claims (18)
