Flip-flops in a monolithic three-dimensional (3D) integrated circuit (IC)(3DIC) and related method are disclosed. In one embodiment, a single clock source is provided for the 3DIC and distributed to elements within the 3DIC. Delay is provided to clock paths by selectively controllable flip-flops to help provide synchronous operation. In certain embodiments, 3D flip-flop are provided that include a master latch disposed in a first tier of a 3DIC. The master latch is configured to receive a flip-flop input and a clock input, the master latch configured to provide a master latch output. The 3D flip-flop also includes at least one slave latch disposed in at least one additional tier of the 3DIC, the at least one slave latch configured to provide a 3DIC flip-flop output. The 3D flip-flop also includes at least one monolithic intertier via (MIV) coupling the master latch output to an input of the slave latch.

The invention belongs to the technical field of testing moving parts such as a membrane and the like, and more particularly discloses a multifunctional membrane testing device which comprises a test bench component, an electric control cabinet component and a pneumatic component; wherein, the electric control cabinet component comprises a power supply, a programmable controller (PLC) connected with the power supply and two intermittent on-off selective control valves which are respectively and correspondingly connected on two pins of the PLC; the pneumatic component comprises a high pressure air source, a moisture separator and two airflow branches formed by respectively connecting the moisture separator with the two selective control valves, wherein, one of the airflow branches is communicated with a positive pressure gas discharge pipe, and the other one is connected with a negative pressure generator and a negative pressure gas discharge pipe and communicated with the parts to be tested, so that negative pressure is formed for testing the parts to be tested by vacuum-pumping. The testing device can accurately control the negative pressure applied on the objects to be tested, meet the strain resistance and corrosion resistance tests of dynamic and static rubber mebranes, and accurately control the frequency, time and count of the movement of the mebrane without needing a person specially assigned for monitoring, thereby improving the working efficiency of the test and greatly reducing the energy consumption.

The invention discloses a feeding traveling crane system, which is used for feeding operation of ladder type or cascade type cage culture equipment. The feeding traveling crane system comprises a feeding traveling crane, a control device, a remote control terminal, and a security device. The feeding traveling crane is arranged on a travelling guide rail of the cage culture equipment. The control device is electrically connected to the feeding traveling crane and is connected to the remote control terminal through communication. The security device is installed on the cage culture equipment andis electrically connected to the control device. Through the cooperation among the feeding traveling crane, the control device, the remote control terminal, and the security device, switching among multiple control modes and safety control are realized. The control mode can be selected according to the feeding scene, the efficiency of feeding operation is largely improved; and the problem that the efficiency of feeding operation of a conventional feeding traveling crane is not high is solved. By using the feeding traveling crane system, through the remote control terminal and security device,the feeding traveling crane is safely and reliably controlled to carry out predetermined feeding operation, the feeding travelling crane does not need to be monitored in real time, and the feeding operation efficiency is high.
