According to the high-precision high-speed synchronous shearing device, the synchronous belt moving synchronously is arranged on one side of the sliding rail, the synchronous belt is clamped through the clamping assembly, synchronous movement of the shearing assembly and the to-be-sheared piece is achieved, and damage to the to-be-sheared piece is avoided.

The utility model relates to a kind of block forming machine demolding synchronous devices, including synchronous gear, synchronous frame and two parallelly arranged synchronous shafts, both ends of each the synchronous shaft are equipped with synchronous gear, and the same side end of two synchronous shafts is connected by synchronous frame, the synchronous frame includes adjusting frame, connecting rod, demolding ejector rod and two parallelly arranged racks, the tooth surface of two racks is oppositely arranged, and two racks are respectively engaged with the synchronous gear on corresponding synchronous shaft, the connecting rod is connected in the lower end of two racks, the demolding ejector rod is connected in the upper end of two racks, the position of the rack on connecting rod and demolding ejector rod is adjustable, and the both ends of adjusting frame are equipped with adjusting bolt in pairs, and the adjusting bolt of the both ends of adjusting frame is respectively abutted on the outside of two racks. The block forming machine demolding synchronous device of the utility model can ensure the engagement of rack and gear by adjusting.

In a 802.11be multi-AP collaboration, collaborated BSSs obtaining shared resource from a collaborator AP. Co-channel interferences arise from misalignment of PHY preambles between the various collaborated and collaborator BSSs. This misalignment results from the independency of each BSSs during the shared TXOP. To overcome this deficient situation, a synchronization frame is sent by the collaborator AP at a predefined sync time over the shared frequency bands, even if the collaborator AP does not belong to the BSSs operating on these bands. The predefined sync time may derive from the UL Length field specified in the initial trigger frame. Consequently, all the stations are ready to receive the synchronization frame and therefore to start again their MU or P2P transmission a SIFS after the synchronization frame. PHY preambles in adjacent channels are therefore fully aligned.

A synchronous framing data acquisition and processing system based on a TTE bus comprises a data integration device, a network switch and a plurality of data acquisition devices. According to the transmission data volume of the TTE bus single virtual link, the communication period Ti of the data acquisition equipment is configured; virtual link planning is carried out according to the full frame number L of the telemetry data, and TT frame data is split into a plurality of small frame data; and transmitting the TT frame data split into a plurality of small frame data to the data comprehensive equipment through the network switch according to the communication period Ti, thereby completing the transmission of all the TT frame data in the cluster period T. According to the invention, super-large-scale, high-capacity, high-real-time and high-reliability telemetry data comprehensive framing based on the TTE bus can be realized.
