MATTRESS WITH CAPACITIVE IMMERSION CONTROL |
摘要 |
A mattress and a capacitive immersion system for adjusting the support that the mattress provides to a user are disclosed. In one embodiment, a mattress includes one or more air cells and a capacitive immersion system. The system relates generated capacitance between conductors mounted to an air cell to a pressure inside the air cells on which the conductors are mounted. More specifically, the measured capacitance may be related to a distance between the conductors. This distance may then be related to pressure with the air cells. The air cell may be inflated or deflated as required or desired to maintain a suitable minimum distance or distance that a user finds to be subjectively comfortable.
