Abstract: A semi-automatic adjustment device for suppressing tension fluctuations during a rolling process of an ultra-thin strip includes a semi-automatic tension regulator, a semi-automatic tuned mass damper of variable stiffness and damping, a coiler, a tension roller and a twenty-high roller system. The semi-automatic tension regulator is disposed between the coiler and the tension roller, the semi-automatic tuned mass damper of variable stiffness and damping is disposed between the tension roller and the twenty-high roller system. The semi-automatic adjustment device can be used to reduce a short-time fluctuation impact of tension during startup and shutdown of a twenty-high roll mill when the twenty-high rolling mill rolls an ultra-thin strip, improve system stability, absorb the continuous micro disturbances generated during the rolling process of the twenty-high roll mill, and achieve flexible and stable adjustment of tension during the rolling process.

Abstract: A method and a system for constructing a driving coordinate system for use in the field of smart transport. The method for constructing a driving coordinate system comprises: determining the road boundary line on one side of the road on which a current vehicle is situated as a reference line for constructing a driving coordinate system; in a vehicle coordinate system, determining the reference line point having the smallest distance between the reference line and the current vehicle position as an origin point OF of the driving coordinate system; on the basis of the origin point OF, determining the road guiding line direction as the XF axis of the driving coordinate system and determining the direction relative to the road guiding line direction according to the left-hand rule as the YF axis of the driving coordinate system; and, on the basis of the origin point OF, the XF axis, and the YF axis, forming a corresponding driving coordinate system.

Abstract: Techniques for implementing a QRAM by routing quantum information through multiple modes of a bosonic system are described. According to some aspects, a single bosonic system may be configured to maintain quantum information in a large number of independent modes at the same time. Suitable operations upon these modes may allow a quantum address value to be routed to modes associated with respective bits such that the only modes altered by the operations are those associated with the addresses being accessed. These modes may be operated upon based on the stored values then extracted to obtain the desired correlated superposition of the stored bit values in the addresses. The bits stored at the address locations may be classical bits, or may be qubits.

Abstract: Reconfigurable front-end module for carrier aggregation. In some embodiments, a front-end module can include a plurality of signal ports and a plurality of antenna ports. The front-end module can further include a switch assembly configured to route signals along one or more of a plurality of filtering paths between the signal ports and the antenna ports. Each of the filtering paths can include a filter, and the filtering paths can be configured to allow the antenna ports to be combined outside of the front-end module to accommodate a corresponding antenna configuration. The filtering paths can be further configured to maintain desirable filtering performance levels for different combinations of the antenna ports outside of the front-end module corresponding to the different antenna configurations.

Abstract: An integrated circuit having a resonant circuit is provided. The resonant circuit may include an inductor and a capacitor coupled in parallel. The inductor may be formed in a dielectric stack on a semiconductor substrate. An inductor shielding structure may be interposed between the inductor and the semiconductor substrate in the dielectric stack. The inductor shielding structure may be a closed loop structure that is electrically floating. The inductor shielding structure may also be formed using a figure 8 routing arrangement that is symmetrical to help cancel out any induced current from the inductor. A resonant circuit formed in this way may exhibit an enhanced Q factor.
