  • Patent number: 11934027
    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.

  • Patent number: 10953506
    Abstract: A self-balancing line shaft of a machine tool includes a spindle device, a cutter tool holder and at least one balancing assembly. The spindle device includes a spindle extending along and rotatable about an axis, and at least one precision lock nut threadedly engaged with and rotated with the spindle. The cutter tool holder is coaxially connected and rotated with the spindle. The balancing assembly includes an annular groove formed in one of the precision lock nut and the cutter tool holder and extending along a circle path surrounding the axis, and a plurality of weight members disposed in the annular groove to be moved in a direction opposite to a rotation unbalance during rotation of the spindle such that the center of mass of the whole rotating system is close to the axis.
