  • 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: 4239269
    Abstract: A luggage lock for locking together the two shells of a luggage case. The lock includes a housing adapted to be mounted in one of the luggage case shells and which is secured to the shell by a threaded cap. A hook member is adapted to be mounted in the other one of the luggage case shells. A button is reciprocally mounted in the housing for movement between retracted and projected positions. A spring is positioned between the button and the cap to bias the button to its outward retracted position. The button includes a locking edge portion which projects into the path of travel of the hook when the case is closed whereby the hook end engages and overlies the locking edge to fasten the lock. The lock is unfastened by displacing the button to its projected position, against the action of the spring, to disengage the hook end from the locking edge to permit the case to be opened.
