Abstract:
1. A sensing device in an air cushion bed outside a plurality of air bladders, comprising: a first sheet including a plurality of inflation valves; a second sheet connected to the first sheet, such that an air chamber is formed between the connected first and second sheets, a first sensing element disposed outside the air chamber and having at least one deformation sensor and at least one acceleration sensor provided thereon; and a second sensing element disposed inside the air chamber, and including an upper conductive sensing sheet attached to an inner upper side of the air chamber and a lower conductive sensing sheet attached to an inner lower side of the air chamber; and a monitoring device electrically connected to the first and the second sensing elements configured to determine and analyze data from the deformation sensor and the acceleration sensor, wherein the monitoring device is further configured to determine and analyze an electrical connection state between the upper conductive sensing sheet and the lower conductive sensing sheet, wherein the monitoring device is configured to detect whether the air bladders are sufficiently inflated via a contacting state between the upper conductive sensing sheet and the lower conductive sensing sheet.
