  • Patent number: 10803306
    Abstract: A releasing method of an image capturing module of an electronic device, including an electronic device, wherein the electronic device includes a first machine body and an image capturing module pivotally connected to the first machine body, and the image capturing module is restrained by the first machine body to approach to the first machine body. Performing a posture estimation procedure includes, sensing a first included angle between the first machine body and a gravity direction for determining whether the electronic device is in a tent position. When the electronic device is determined to be in the tent position, determine whether a release instruction is received, so as to decide whether to perform a release procedure, wherein when the release procedure is performed, the first machine body releases the image capturing module, so that the image capturing module is turned up relative to the first machine body.

  • Publication number: 20110308961
    Abstract: A pattern processing method of a workpiece surface includes at least the following steps. A first anodized process is performed to a workpiece, wherein a surface of the workpiece includes at least one flat portion and at least one curved portion. A patterned film including a releasable substrate and an acid-base resistant ink layer disposed thereon is provided, wherein a surface of the releasable substrate on which the acid-base resistant ink layer is disposed faces the workpiece. A force is applied to an edge of the patterned film to adhere the patterned film the workpiece smoothly, so as to transfer a pattern of the acid-base resistant ink layer to the workpiece. The releasable substrate is removed. The workpiece is etched and the acid-base resistant ink layer is removed; and a second anodized process is performed to form a dichromatic anode three-dimensional texture.
