摘要:
A fast-setting DC offset removal circuit with continuous cutoff frequency switching is disclosed. In the preferred embodiment, the circuit is implemented using a pair of RC filters for receiving a differential signal pair and a continuous, variable resistance control circuit. The control circuit can be current-controlled or voltage controlled to provide fast settling of the received signal and the removal of the DC offset components. Additionally, by using a current-controlled control circuit, the cutoff frequency of the RC filter can be ramped from high to low in a continuous manner, thereby minimizing the generation of DC offsets.

An integrated medicine mixing interface comprising a medicine mixing mouth (1), hard double interfaces (2) and a medicine feed needle (3). The hard double interfaces (2) comprise a base (21), a medicine mixing interface (22) and an infusion interface (23). The medicine mixing mouth (1) and the medicine mixing interface (22) are integrated. When using the integrated medicine mixing interface, it is only necessary to weld the base (21) to the bag body of a soft infusion bag (11) and integrate the medicine mixing mouth (1) with the medicine mixing interface on the hard double interfaces (2) without adopting a hose connection and an easily folding handle, which not only reduces hose installation location, but also avoids welding leakage brought about by hose welding defects. Moreover, the structure is simple and the costs are low.

A doser having two needles. The two needles consist of a needle seat (1), an upper needle (2), and a lower needle (3). The upper needle (2) and the lower needle (3) are arranged at two sides of the needle seat (1), and the upper needle (2) and the lower needle (3) both have a hollow structure and are in communication with each other. A medicine mixing body (4) of a cup structure is formed through extension in the direction along the edge of the needle seat (1) toward the upper needle (2). When the doser having two needle is used, it is only required that the upper needle (1) penetrates through a sealing plug of a medicine container and the lower needle (3) simultaneously penetrates through a sealing plug inside a sealing cover on a transfusion container, and by squeezing the transfusion container, medicine in the medicine container can be mixed with a solution in the transfusion container, which makes the medicine mixing operation simpler and more time saving.

A data transmission method is provided. The method is used to transmit multiple data packets, and includes the following steps. Multiple acquired data packets are mapped to different sessions according to data header information of the data packets, in which each session corresponds to one or more data packets. A data packet is encapsulated into a session message, in which the encapsulated session message includes a session identifier of the session corresponding to the one or more data packets. Multiple session messages belonging to the same session are transmitted to a next network node through at least two tunnels in link layer.

In the field of communications, a method and a system for packet transmission in an optical communication system, and an Optical Line Terminal (OLT) are provided. The method includes: receiving, from a port, a first uplink packet from an Optical Network Unit (ONU), where the first uplink packet includes a Logical Link Identifier (ID); determining a first ID corresponding to the first uplink packet, where the first ID includes an ONU ID or a Port ID; acquiring a Multiprotocol Label Switching (MPLS) tunnel label according to the Logical Link ID and the first ID; and transmitting a second uplink packet on an MPLS tunnel corresponding to the MPLS tunnel label, where the second uplink packet includes data in the first uplink packet and the MPLS tunnel label. The system includes an ONU and an OLT. By establishing a corresponding relation of a logical link, created between the OLT and the ONU, and the MPLS tunnel, mapping between the logical link and the MPLS tunnel is realized, so that the service configuration has an unlimited capacity and becomes more flexible.

摘要:
A binding/unbinding processing method, system and apparatus are disclosed. The binding processing system includes: an Internet Protocol (IP) edge node and an Access Node (AN). The IP edge node is configured to: monitor received Dynamic Host Configuration Protocol (DHCP) messages, after monitoring a specific DHCP message, forward the specific DHCP message to all ANs corresponding to bound links, where the specific DHCP message is a DHCP ACK or DHCP REPLY message. The AN is configured to: receive the specific DHCP message sent by the IP edge node, parse and obtain an IP or Media Access Control (MAC) address carried in the specific DHCP message, and bind a port of the AN to the IP or MAC address according to the obtained IP address or MAC address. The present disclosure implements the binding/unbinding of an AN port to/from an IP or MAC address in inter-AN binding scenarios.

A method and a system for forwarding data in layer-2 network are disclosed. The method includes: configuring a virtual MAC address and a virtual MAC forwarding table for each node in a management domain in a layer-2 network; encapsulating a data packet with a source virtual MAC address and a destination virtual MAC address; and forwarding the data packet by each node on the data forwarding path according to the virtual MAC forwarding table configured for each node. A node and a system for forwarding data in layer-2 network are disclosed as well. The present disclosure frees the number of ESPs reaching a destination device from being limited by the number of designated PBT VIDs. Therefore the number of ESPs arriving at the destination device is expanded actually to 260 tag possibilities in limited network space; furthermore, P2MP and MP2MP connections is achieved, multicast and broadcast connections are supported.
摘要:
A preassembled medicine mixer comprises a rotary sleeve (4), a guide sleeve I (3), a guide sleeve II (6), a guide part, a dosing barrel (1), and a dosing double needle (2). The guide sleeve I (3) extends into the guide sleeve II (6) and is connected to the rotary sleeve (4). A guide groove (8) is provided on the side wall of the guide sleeve I (3), and two ends of the guide groove (8) are extended by a distance towards opposite directions. A guide spiral groove (7) is provided on an inner wall of the guide sleeve II (6). The guide part is disposed in the guide sleeve I (3) and has a guide block (9) at the outer side thereof. The guide block (9) penetrates through the guide groove (8) and extends into the guide spiral groove (7). In use, the rotary sleeve (4) is rotated to drive the guide part to rapidly move downwards and push a medicine container (17); an upper needle tip of the dosing double needle (2) pierces a sealing plug on the medicine container (17), and a lower needle tip pierces a diaphragm (23) in an interface (22), so that the medicine container (17) is instantly communicated with an infusion container (14), thereby implementing sterile closeness during the entire process of transportation, storage, butt joint, medicine mixing, and infusion.
