Patent number: 10406044Abstract: A person support apparatus includes a base, wheels, a drive system, a support surface, a lift system, and a control. The control controls the drive system in response to forward/reverse forces applied thereto, and also controls the lift system in response to upward or downward forces applied thereto. In some embodiments, a controller compares a magnitude of the forward/reverse force to a magnitude of the upward/downward force and commands the drive system to drive the wheels if the magnitude of the forward/reverse force exceeds the magnitude of the upward/downward force. The control may include a user-engageable portion that is constructed to not move with respect to a force sensor when forward or reverse forces are applied to the user-engageable portion. The controller controls the drive system in response to the forward or reverse forces applied to the user-engageable portion.Type: GrantFiled: June 22, 2016Date of Patent: September 10, 2019Assignee: Stryker CorporationInventors: Jerald A.
