Abstract

Aspects herein are directed to systems and methods for synchronization of actuators to reposition furniture units. Specifically, a master control box receives input to reposition a furniture unit from one position to another and communicates the input to a plurality of control boxes. Then, each of the plurality of control boxes assigns a virtual axis to each of a plurality of actuators attached to each associated control box. Furthermore, each of the plurality of control boxes assigns a transfer function to each of the plurality of actuators. The transfer function is used by the actuators to transform an output of the virtual axis to determine a target position. In this way, the plurality of actuators can reference the same virtual axis for synchronization purposes, but use different transfer functions to maintain complex relationships between the positions of each actuator. Based on the target position, the actuators reposition the furniture unit.

First claim

What is claimed is:

1. A system comprising a furniture unit operably coupled to a plurality of control boxes, a master control box, a plurality of actuators, a plurality of sensors, a plurality of communication busses, and at least one computing device, the system configured to perform a method for repositioning the furniture unit comprising the steps of:
receiving, at the master control box, an input to reposition the furniture unit, using the plurality of actuators, from a first position to a second position;
communicating the input to the plurality of control boxes, by the master control box, the master control box communicatively coupled to each one of the plurality of control boxes using one of the plurality of communication busses;
assigning, by each one of the plurality of control boxes, a virtual axis to each of the plurality of actuators, wherein each one of the plurality of control boxes is associated with at least one of the plurality of actuators;
assigning, by each one of the plurality of control boxes, a transfer function to each of the plurality of actuators, wherein the transfer function is used to determine a target position for each of the plurality of actuators; and
based on determining the target position, repositioning the furniture unit from the first position to the second position.

2. The system of claim 1 , wherein the master control box maintains a current linear position of each virtual axis associated with the furniture unit.

3. The system of claim 1 , wherein based on the input the master control box coordinates a plurality of commands for the virtual axis assigned to each of the plurality of actuators, the coordinating occurring using the plurality of communication busses, the plurality of communication busses connecting the plurality of control boxes.

4. The system of claim 1 , wherein the input is provided by an external source, the external source comprising buttons on the furniture unit, Bluetooth remotes, phones, tablets, home automation systems, Wi-Fi devices, or a combination thereof.

5. The system of claim 1 , wherein the input is provided by an internal source, the internal source comprising decisions based on furniture unit occupancy, user detection, Bluetooth device proximity, Wi-Fi device proximity, or a combination thereof.

6. The system of claim 1 , wherein the virtual axis is an abstracted linear motion simulation.

7. The system of claim 1 , wherein determining the target position is further based on an output associated with the virtual axis assigned to each of the plurality of actuators.

8. The system of claim 1 , wherein the master control box further controls a plurality of massage motors.

9. The system of claim 1 , wherein the master control box further controls light emitting diode (LED) lights, the master control box configured to support LED synchronization and Gamma correction.

10. A system comprising a furniture unit operably coupled to a plurality of control boxes, a master control box, a plurality of actuators, a plurality of sensors, a plurality of communication busses, and at least one computing device, the system configured to perform a method for repositioning the furniture unit comprising the steps of:
receiving, at the master control box, an input to reposition the furniture unit, using the plurality of actuators, from a first position to a second position;
communicating the input to the plurality of control boxes, by the master control box, the master control box communicatively coupled to each one of the plurality of control boxes using one of the plurality of communication busses;
assigning, by each one of the plurality of control boxes, a virtual axis to each of the plurality of actuators, wherein the virtual axis assigned to each of the plurality of actuators is the same virtual axis, wherein the virtual axis is an abstracted linear motion simulation, wherein the master control box maintains a current linear position of each virtual axis associated with the furniture unit, wherein each one of the plurality of control boxes is associated with at least one of the plurality of actuators;
assigning, by each one of the plurality of control boxes, a transfer function to each of the plurality of actuators;
determining a target position for each of the plurality of actuators using the transfer function and an output associated with the virtual axis assigned to each of the plurality of actuators; and
based on determining the target position, repositioning the furniture unit from the first position to the second position, wherein based on the input the master control box coordinates a plurality of commands for the virtual axis assigned to each of the plurality of actuators, the coordinating occurring using the plurality of communication busses, the plurality of communication busses connecting the plurality of control boxes.

11. The system of claim 10 , wherein the input is provided by an external source, the external source comprising buttons on the furniture unit, Bluetooth remotes, phones, tablets, home automation systems, Wi-Fi devices, or a combination thereof.

12. The system of claim 10 , wherein the input is provided by an internal source, the internal source comprising decisions based on furniture unit occupancy, user detection, Bluetooth device proximity, Wi-Fi device proximity, or a combination thereof.

13. The system of claim 10 , wherein the master control box disallows certain movements of at least one of the plurality of actuators until at least another one of the plurality of actuators is in a predetermined position.

14. The system of claim 10 , wherein the master control box further controls a plurality of massage motors.

15. The system of claim 10 , wherein the master control box further controls light emitting diode (LED) lights, the master control box configured to support LED synchronization and Gamma correction.

16. The system of claim 10 , wherein the master control box further controls motor lock-out which temporarily disables one or more actuators.

17. The system of claim 10 , wherein the master control box further controls an actuator position recall function that, without repeating any calibration procedures, restores previous positions of the plurality of actuators if the control box is powered off and then back on.

18. A furniture unit comprising:
a plurality of control boxes;
a master control box;
a plurality of actuators, wherein each one of the plurality of control boxes is associated with at least one of the plurality of actuators;
a plurality of sensors;
a plurality of communication busses connecting the plurality of control boxes, wherein the master control box is communicatively coupled to each one of the plurality of control boxes using one of the plurality of communication busses;
at least one computing device; and
a system operably coupled to the plurality of control boxes, the master control box, the plurality of actuators, the plurality of sensors, the plurality of communication busses, and the at least one computing device, the system configured to perform a method for repositioning the furniture unit comprising the steps of:
receiving, at the master control box, an input to reposition the furniture unit, using the plurality of actuators, from a first position to a second position,
communicating the input to the plurality of control boxes, by the master control box,
