Abstract: In the operation of analytical devices, and particularly laser induced breakdown spectroscopy (LIBS) devices, a number of advantages may be obtained by the use of complementary safety mechanisms, such as those that govern the operation or firing of a laser. Such complementary safety mechanisms, compared to the individual safety mechanisms acting alone, prevent operation of the laser under a greater number of unsafe circumstances (even if one or more detected conditions are safe, based on not activating the associated safety mechanism) and permits operation under a greater number of safe circumstances (even if one or more detected conditions are unsafe, based on activating the associated safety mechanism).

Abstract: A dynamic system for a lifting apparatus is disclosed. The dynamic system includes a first motor and a second motor decoupled from the first motor. During the ascent of the lifting apparatus, only the first motor is involved in the driving of the lifting apparatus. During the descent of the lifting apparatus, only the second motor is involved in charging the battery system. Since the first motor and the second motor are decoupled from each other, the first motor can have a high driving efficiency and the second motor can have a high power generation efficiency, the problem that when only one motor is adopted, the motor needs to balance between the driving efficiency and power generation efficiency is solved. The energy recovery rate of this invention can be increased from 10% in the prior art to about 30%.

Abstract: A packet processing method, node, and system. An ingress delivery node receives a notification message that is returned by an egress delivery node after the egress delivery node receives a first packet, where the notification message includes modification information carried in the first packet, modifies, according to the modification information, a subsequently received second packet that belongs to a same service flow as the first packet, and sends the modified second packet to the egress delivery node. After modifying the subsequently received second packet that belongs to the same service flow as the first packet, the ingress delivery node directly sends the subsequently received second packet to the egress delivery node such that the second packet does not need to be processed by a service chain between the ingress delivery node and the egress delivery node.
