Abstract: A pulmonary function identifying method includes: obtaining a first image, having first image elements, and a second image, having second image elements, respectively corresponding to a first state and a second state of a lung; extracting first feature points of the first image and second feature points of the second image; registering the first image with the second image using a boundary point set registeration method and an inner tissue registeration method according to the first feature points and the second feature points, so that the first image elements correspond to the second image elements and tissue units of the lung; and determining functional index values representative of the tissue units of the lung using a ventilation function quantification method according to the first image elements and the second image elements corresponding to the first image elements.

Abstract: A waterproof casing for an electronic device has a body, a cover module and multiple fixers. The body has two connecting assemblies respectively mounted on two side surfaces of the body and each connecting assembly has two wings and a trough defined between the wings and the corresponding side surface of the body. The cover module has a first cover and a second cover respectively mounted on two ends of the body. The fixers are respectively inserted into a corresponding one of the first cover or the second cove and are steadily mounted with the body. The types of the cover module can be changed to fit with an electronic device installed in the body. Therefore, the combination between the body and the cover module is variable, and the waterproof casing has good applicability.
