Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: A portable computing device including a central processing unit (CPU) and a controller is provided. The controller is coupled between the CPU, a graphics processing unit, and a battery module. The controller determines whether to adjust performance of the CPU and the graphics processing unit according to at least one of a battery capacity, a battery power, a battery current, a battery voltage, or a battery temperature of the battery module.

Abstract: A semiconductor structure is provided. The semiconductor structure includes a substrate and a metallization layer. The metallization layer is disposed over the substrate. The metallization layer includes a first signal line, a second signal line, and a third signal line, wherein the first signal line, the second signal line, and the third signal line are arranged in a first row between a power rail and a ground rail parallel to the power rail. A first distance between the first signal line and the second signal line is different from a second distance between the second signal line and the third signal line. A method for manufacturing a semiconductor structure is also provided.
