-The jack should be retrofitted with a lightweight metal frame that makes a sturdy seat.  Car jacks have a lift capacity that is overkill; production models of this concept could involve lighter materials and a smaller motor.

 Optionally the lift pad could be outfitted with a telescoping handle and wheels like carry-on luggage, allowing it to be rolled instead of carried.

 =Goal and specifications=
-Develop a portable electrically powered device that assists the caregiver with the sit-to-stand operation.  A single device should work with a wheelchair, lounge chair, or other seat, so that only one extra device need be carried on trips.  The device should be capable of lifting a subject weighing 200 lbs at least 6 inches.  The less time the better, but 10 seconds for the full lift is a decent target time.  The weight of the entire device should be 20 lbs or less and it should be small enough to be carried on a plane.

You can assume a caregiver is present to help stabilize the operation, but the major lifting force is provided by the device.
