Abstract
A system and method for incorporating occupancy-detecting technology into furniture is provided. More particularly, the invention relates to direct-connect device, system, and method for determining presence with respect to an automated furniture item, such as a recliner mechanism. In some aspects, a sensor is provided based on coupling one or more conductive features to a control component of the capacitance detector control component. A controller may determine the corresponding response based on occupancy detection and/or presence detection. A processor may receive information regarding changes in capacitance and determines when a change in voltage satisfies a threshold. Based on a determination of occupancy and/or presence, a variety of corresponding features of the adjustable recliner may be activated.
