Abstract: Provided are a feedback sequence transmission method and apparatus, and a device and a readable storage medium, belonging to the field of communications. The method comprises: receiving data in a data channel, wherein the data corresponds to received power and transmitted power; determining the number of transmissions of a feedback sequence according to the received power and the transmitted power; and transmitting the feedback sequence according to the number of transmissions. The number of transmissions of the feedback sequence is determined according to the transmitted power and the received power of the data channel, and the feedback sequence is retransmitted according to the number of transmissions. That is, when the transmitted power and the received power indicate that the power loss of the feedback sequence during a transmission process is relatively high, the feedback sequence is retransmitted multiple times, so as to avoid the problem of a feedback sequence with a relatively low received power being unable to be interpreted due to the fact that a sequence with a relatively low received power may be submerged by a sequence with a relatively high received power, thereby improving the accuracy of transmission of the feedback sequence.

Abstract: Dual-motor clip applying forceps, comprising an operating head (1), and a first motor (2), a second motor (3), a first driving assembly (4), a second driving assembly (5), and a clip compartment assembly that are disposed in the operating head (1). The clip compartment assembly comprises a clip compartment (6) for accommodating a ligature clip and a clip clamp (7) arranged on one side of the clip compartment (6). The operating head (1) is further provided with a firing lever (11) and a clip pushing lever (12). The firing lever (11) is connected to the clip clamp (7) to drive the clip clamp (7) to open or fire. The first driving assembly (4) is connected to the firing lever (11) and the first motor (2), and the second driving assembly (5) is connected to the clip pushing lever (12) and the second motor (3). The clip pushing lever (12) pushes the ligature clip within the clip compartment (6) into the clip clamp (7). The dual-motor clip applying forceps solve the problem of conventional clip applying forceps, in which clip feeding and firing movements need to be completed by using a single shaft and have significant dependencies and constraints, which are likely to cause operational errors. The clip applying forceps are controlled by dual motors, thereby simplifying operations, increasing the degree of freedom, and reducing error rates.

Abstract: A high-orientation collector for a lithium ion battery, a fabrication method therefor and an application thereof. The collector is made by adding a resin material of conductive particles. The conductive particles of the collector in the X-Y direction do not form a fully conductive network, but form a relatively good conductive network in the Z direction. When short circuiting occurs, the collector does not easily active the majority of active substances in the X-Y direction, and thus is not prone to thermal runaway. However, the collector may also fully conduct in the Z direction, so that a battery can be charged and discharged normally. Therefore, the safety of the battery is improved.
