Abstract:
A system and method for incorporating presence-sensing technology into furniture is provided. More particularly, the invention relates to detecting presence using a metal, adjustable bed frame. The bed frame is pulsed with a voltage to provide a charge, against which capacitance is measured. A controller determines the corresponding response based on presence detection by the frame. Conductive bushings may also be used to measure capacitance using the bed frame. In further embodiments, capacitance is measured by a foil tape surrounding a perimeter of the adjustable bed. The foil tape has a voltage based on proximity of an object to the tape, and may be embedded with a capacitive wire. A processor receives information regarding changes in capacitance and determines when a change in voltage satisfies a threshold. Based on a determination of presence, or lack of presence, a variety of corresponding features of the adjustable bed may be activated.
