    • 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.
    • 提供了一种将现有感测技术纳入家具的系统和方法。 更具体地,本发明涉及使用金属可调式床架来检测存在。 床架用电压脉冲以提供电荷,测量电容。 控制器基于帧的存在检测来确定相应的响应。 也可以使用导电套管来使用床架来测量电容。 在另外的实施例中,通过围绕可调节床的周边的箔带来测量电容。 箔带具有基于物体与带的接近度的电压,并且可以嵌入电容线。 处理器接收关于电容变化的信息,并确定电压变化何时满足阈值。 基于存在或不存在的确定,可以激活可调节床的各种相应特征。
