Abstract

This disclosure concerns a wireless communication system adapted to produce a closed-loop feedback scheme between a handheld remote control and an adjustable bed controller. The adjustable bed controller is adapted to, in response to a receipt of a motion command from the handheld remote control via the closed-loop feedback scheme, adjust, with feedback, a portion of an adjustable bed. The feedback is based on a comparison of sensor feedback and a predetermined position stored in a memory of the adjustable bed controller. The handheld remote control can receive, through the closed-loop feedback scheme, a returned confirmation reflecting the state of the position of the bed segment in response to the control signal.

Claims

1. A control system, comprising:

a wireless communication system adapted to produce a closed-loop feedback scheme between a handheld remote control and at least an adjustable bed controller, the adjustable bed controller adapted to, in response to a receipt of a motion command from the handheld remote control, adjust, with feedback, a portion of an adjustable bed;

wherein the feedback is based on a comparison of sensor feedback and a predetermined position stored in a memory of the adjustable bed controller;

the handheld remote control capable of transmitting a control signal for an articulating adjustment of the position of a bed segment to the adjustable bed controller using the closed-loop feedback scheme; and

the handheld remote control further capable of receiving, through the closed-loop feedback scheme, a returned confirmation reflecting the state of the position of the bed segment in response to said control signal.

2. The system of claim 1, wherein the bed controller receives feedback from a plurality of bed segments in response to said control signal and wherein said bed controller coordinates movement of the plurality of bed segments.
