发明名称 Adaptable surface for use in beds and chairs to reduce occurrence of pressure ulcers
摘要 An adaptable surface system including a plurality of individually adjustable surface units and a plurality of pressure sensors. Each pressure sensor corresponds to one of the adjustable subsurface units and is positioned to measure an amount of pressure exerted upon the subsurface unit. The system also includes a controller that receives a first pressure value from a pressure sensor, compares the value to a threshold, and adjusts the height of the first subsurface unit based on the comparison. The controller also receives a second pressure value from a second pressure sensor, compares the second pressure value to the threshold, and adjusts the height of a second subsurface unit based on the comparison.

主权项 1. An adaptable surface system comprising: a surface including a plurality of individually adjustable subsurface units; a plurality of subsurface pressure sensors, each pressure sensor of the plurality of subsurface pressure sensors corresponding to one of the plurality of individually adjustable subsurface units and positioned to measure an amount of pressure exerted upon the corresponding subsurface unit; a controller including a processor and a computer readable memory storing computer instruction that, when executed by the processor, cause the controller to: receive a first pressure value from a first subsurface pressure sensor of the plurality of subsurface pressure sensors, the first subsurface pressure sensor corresponding to a first subsurface unit,compare the first pressure value to a threshold,adjust a height of a first subsurface unit relative to the surface based upon the comparison of the first pressure value and the threshold,receive a second pressure value from a second subsurface pressure sensor of the plurality of subsurface pressure sensors, the second subsurface pressure sensor corresponding to a second subsurface unit,compare the second pressure value to the threshold, andadjust a height of a second subsurface unit relative to the surface based upon the comparison of the second pressure value and the threshold; and a sensor positioner, the sensor positioner being physically coupled to the surface and movable across the surface to exert a pressure on the surface such that, when the sensor positioner is positioned on the first substrate, the pressure is detected by the first substrate pressure sensor and the height of the first substrate is adjusted.
