Abstract: Disclosed in the present invention is an adjustable inductor, and a transmission circuit for magnetic resonance. The adjustable inductor comprises a fixing assembly, an inductance assembly and a sliding assembly. The inductance assembly is electrically connected to the fixing assembly. The sliding assembly is electrically connected to the fixing assembly and the inductance assembly, and is configured to be able to change the contact position with the inductance assembly so as to change the inductance value of the inductance assembly.

Abstract: The present disclosure provides a magnetic resonance system and circuit. The system includes a magnetic resonance transmitter configured to generate one or more radio frequency signals, a magnetic resonance receiver configured to receive one or more magnetic resonance signals collected by one or more coils, and a magnetic resonance radio frequency power transceiver including a communication circuit and a control circuit. The communication circuit provides a first communication circuit and a second communication circuit. The first communication circuit is configured to transmit the one or more radio frequency signals to the one or more coils. The second communication circuit is configured to transmit the one or more magnetic resonance signals to the magnetic resonance receiver. The control circuit is configured to send one or more control signals to the communication circuit to control the first communication circuit or the second communication circuit to turn on or cut off.

Abstract: Method and apparatus for command synchronization is described. In some embodiments, a remote system may set up a user interactive session with a local device according to a user interaction protocol. The remote system may insert a predetermined execution time into a first command and send the first command to a local device according to the user interaction protocol. The first command, when executed on the local device, causes a second command compliant with the user interaction protocol to execute on the local device at the predetermined execution time.

Abstract: Machine-readable media, methods, and apparatus are described for dynamic content play control. In some embodiments, a client device (11) may receive a mark associated with a content piece from a remote system (10) connecting with the client device (11) through a network. The client device (11) may determine whether to play the content piece by checking the mark with a policy table comprising a plurality of marks. The policy table may indicate whether each of a plurality of content pieces associated with each of the plurality of marks is acceptable for play.
