Abstract: Disclosed is a tactile sensing device, including a light source, a plurality of optical waveguides, photoelectric sensing components, and a contact point. The light source is disposed at an input end of each optical waveguide, and the photoelectric sensing component is disposed at an output end of each optical waveguide. The plurality of optical waveguides surround the contact point, and the contact point is in contact with each optical waveguide. When there is a contact force at the contact point, the plurality of optical waveguides are deformed, and deformations of the optical waveguides cause losses of optical signals transmitted in the optical waveguides. The photoelectric sensing component obtains an optical signal transmitted by each optical waveguide, and may detect a value and a direction of the contact force based on a variation of the optical signal transmitted by each optical waveguide.

Abstract: Examples of dual core connectors and connection systems are disclosed. In an implementation, a dual core connector comprises a plug assembly and an engagement assembly, the plug assembly comprises a housing and ferrules. The housing has a through hole that penetrates through a first surface and an opposing second surface of the housing. The ferrules are both located within the housing and extend in the length direction of the housing, and axes of the ferrules are separately located at two sides of the through hole. The engagement assembly comprises an engagement member and a shaft body, one end of the shaft body is connected to the engagement member, and the other end of the shaft body is rotatably connected within the through hole, and when the shaft body is rotated relative to the housing into a locked position, the shaft body and the housing can lock together.

Abstract: A packet sending method includes: receiving, by a first node, a first broadcast data packet sent by a second node; and if a sequence number of the first broadcast data packet equals 1 plus a sequence number of a latest data packet saved by the first node, and the first node does not receive, within a first preset time period, a first acknowledgement indication for the first broadcast data packet of the second node, sending, by the first node, a first broadcast acknowledgement packet when the first preset time period elapses, where the first broadcast acknowledgement packet includes the first acknowledgement indication, and the first acknowledgement indication includes the sequence number of the first broadcast data packet and an address of the second node. This method could resolve acknowledgement packet implosion while ensuring broadcast packet reliability of a wireless mesh network.

Abstract: A cable sequence detection method and a detection system. A base station antenna includes N ports, an RRU includes M antenna ports and one calibration port, any port i of the base station antenna corresponds to a directional coupling branch Ti, and a switch circuit Ki whose connection and disconnection are controlled by an RCU is disposed on the Ti. The method includes: the RRU sends a detection signal to the base station antenna through antenna port j; the RCU controls the switch circuit Ki to be disconnected and another switch circuit to be connected; the RRU detects whether energy Qi obtained by the Ti is greater than a threshold; and the RRU determines whether the antenna port j of the RRU is connected to the port i of the base station antenna according to whether Qi is greater than the threshold.
