  • Airbag cushion assembly, intelligent pressure sore prevention cushion, and monitoring system
    Patent number: 11793700
    Abstract: An airbag cushion assembly includes an airbag cushion and an inflation-deflation apparatus that communicates with the airbag cushion. The airbag cushion includes a plurality of sub-airbags, and an airbag gap is formed between adjacent sub-airbags. The inflation-deflation apparatus is provided with an exhaust port, the exhaust port is provided in the airbag gap, and the inflation-deflation apparatus is configured to inflate and deflate the airbag cushion. For the airbag cushion assembly, the exhaust port is provided in the airbag gap, air exhausted by the airbag cushion takes away damp air accumulated between a patient and the airbag cushion, to reduce humidity of the contact area between the patient and the airbag cushion, thereby achieving a pressure sore prevention effect.

  • Silicon wafer pre-alignment device and method therefor
    Patent number: 10276418
    Abstract: A wafer pre-alignment device is disclosed, including a first unit configured to drive a wafer to rotate or move upward or downward, a second unit configured to drive the wafer to translate, and a position detector including a light source, a lens and an image sensor. A light beam from the light source passes through the wafer and the lens and thereby provides information indicating a position of the wafer to the image sensor. The first unit and the second unit are able to adjust the position of the wafer based on the information obtained by the image sensor. A method for pre-aligning a TSV wafer is also disclosed.
