  • Patent number: 11060324
    Abstract: A bag lock and its unlocking method, a first limiting slot is provided at a lock hook. The lock body comprises a lock bolt assembly and a rotating block, the rotating block has a locked state and an unlocked state; when the rotating block is in the unlocked state, the torsion spring provides a twisting force to disengage the first limiting slot from the lock bolt assembly, so that one end of the lock hook opposite to the torsion spring is unlocked from the lock hole to unlock the bag lock; when the rotating block is in the locked state, the rotating block limits a position of the lock bolt assembly so that the lock bolt assembly is kept to be locked inside the first limiting slot, thereby the end of the lock hook opposite to the torsion spring is fixed in the lock hole to lock the bag lock.

  • Patent number: 10490972
    Abstract: In various embodiments, a laser emitter such as a diode bar is cooled during operation via jets of cooling fluid formed by ports in a cooler on which the laser emitter is positioned. The jets strike an impingement surface of the cooler that is thermally coupled to the laser emitter but prevents direct contact between the cooling fluid and the laser emitter itself.
