Abstract: A control system for a piece of furniture includes a control panel configured to receive input from a user, a control module configured to control actuators coupled to movable components of the piece of furniture, and a battery system. The control module is configured to, in response to the input from the user indicating an intent to return the movable components to respective home positions, perform a homing sequence. The homing sequence includes selecting a first actuator according to a specified order, determining a home location for the selected actuator, and beginning to drive the selected actuator toward the home location. The homing sequence includes repeatedly selecting a next actuator according to the specified order and repeating the determining and the beginning. The homing sequence includes determining whether mains electricity is present and, if not, pausing the repeatedly selecting until less than a threshold number of actuators are in motion.

Abstract: A furniture motion control system for controlling movement of one or more movable parts of a furniture member includes a panel including one or more buttons; an actuator configured to control movement of the one or more movable parts of the furniture member; an electric motor configured to drive the actuator; and control circuitry configured to control the electric motor, wherein the control circuitry is configured to, in response to detecting that a first button, from among the one or more buttons, has been pressed, select between controlling the motor to drive the actuator and the one or more movable parts to move automatically and controlling the motor to drive the actuator and the one or more movable parts to move manually, based on a length of time the first button is held.
