Abstract: The method of connection establishment method in data transmission between micro-services in cloud ensures reducing connection complexity between client instances and server instances, increasing the number of connections which helps increase data transmission performance. Besides, the method helps ensure load balancing when server instances change or in time of failure. The proposed method includes the following steps: step 1: data preparation; Step 2: build connection data table; Step 3: select the appropriate connection when receiving a request to send data from the client; step 4: periodically queries the independent service management, updating the current state of the server instances.

Abstract: Disclosed herein is a bidirectional MR actuator comprising a first input member comprising a first rotor, an output member comprising a second rotor and a second input member comprising a housing having a non-magnetic portion and a magnetic portion. Each of the first input member and the output member are coupled to the second input member, the housing defining a chamber for accommodating the first rotor and the second rotor therein and further for receiving a quantity of MR fluid therewithin. The actuator further comprises a magnetic field generation assembly comprising a first coil assembly configured to selectively apply a magnetic field to a portion of the MR fluid between the first rotor and the second rotor, and a second coil assembly configured to selectively apply a magnetic field to a portion of the MR fluid between the second rotor and the magnetic portion of the housing.
