Abstract: Various methods and systems are provided for an integrated arm of an imaging device. In one example, an imaging system may comprise: a base unit; a C-arm coupled to the base unit and including an x-ray source and detector positioned on opposite ends of a C-shaped portion of the C-arm; and a display monitor attached to the C-arm via an integrated arm, wherein the display monitor is movable between a first position on a first side of the C-arm, to a second position on a second side of the C-arm by traveling over a top of an upper half of the C-shaped portion. In this way, the integrated arm may provide a simplified means of orienting the display monitor while promoting better performance of the imaging system.

Abstract: A C-arm X-ray imaging system is provided. The C-arm X-ray imaging system includes a base, an extension arm, a first monitor coupled to the base via a first end of the extension arm, a support, and a second monitor coupled to the base via the support. The first end of the extension arm and the support are vertically aligned and configured to rotate about a common rotational axis to enable independent rotation of the first and second monitors.

Abstract: A method for preparing fluorinated graphene nanoribbons by using fluorine gas as a fluorine source, which includes a step of: fluorinating anhydrous carbon nanotubes in a fluorine gas atmosphere under a pressure of ?0.07˜0 MPa and a temperature of 280˜450° C. to obtain the fluorinated graphene nanoribbons. The method provided is operationally simple, and has a wide variety of raw material sources, low cost, and high production which can reach up to tens of milligrams and even up to hundreds of grams; moreover, the method has simple post-treatment, and can produce fluorinated graphene nanoribbons by a one-step reaction. The prepared fluorinated graphene nanoribbons have very good superhydrophobic properties and chemical stability, and thus can be applied to the anti-icing and other fields, having a very good application prospect.

Abstract: A charging control method, device, and system. The charging control method comprises: a terminal apparatus acquires a feedback voltage of a charging input port, and transmits the same to a charger; and the charger adjusts, according to the feedback voltage, the charger to provide, to the terminal apparatus, a charging voltage, and transmit power to the terminal apparatus.

Abstract: The disclosure provides an X2 handover method and device, the method comprises: after sending a Handover Request Acknowledge message, a target eNB sets, for handed-over UE, a flag for indicating whether or not a Sequence Number Status Transfer message is received and sets the flag to be ‘not received’; and after receiving an RRC Connection Reconfiguration Complete message, the target eNB directly sends a Path Switch Request message to a core network without determining whether or not the Sequence Number Status Transfer message is received. With the technical scheme provided in the disclosure, the problem in the current X2 handover is solved that handover delay is increased as an RRC Connection Reconfiguration completion message is received by a target side prior to a Sequence Number Status Transfer message, thus simplifying the processing of a target eNB and increasing handover speed.
