Abstract

En nedsenkningssensor 12 for bruk med en pute 10 eller madrass 208 for å bestemme den relative nedsenkningen av en person i puten eller madrassen innbefattende en sensor 18, en jord 28 og en krets 30 for å måle kapasitans. Sensoren innbefatter et sjikt med ledende materiale, og jord innbefatter et andre sjikt med ledende materiale. Kretsen er tilpasset å sende korte skurer med elektrisk strøm til sensoren og kondensatoren 46. Kretsen er ytterligere tilpasset å måle tiden det tar strømskurene å lade kondensatoren. Basert på den målte tiden, beregner kretsen nærheten av objektet basert på tiden det tok å lade kondensatoren. En fremgangsmåte som kan implementeres med nedsenkningssensoren, beskrives også.
