摘要： In a method for decoupling an RF transmit coil in a magnetic resonance imaging system, the RF transmit coil has more than one antenna unit and stimulus signals are inputted to said antenna units via connecting cables. A capacitor is connected in series before each of the cables and the value of the series capacitor is such that it just compensates the signal phase shift caused by the connecting cable to zero. Decoupling circuits are connected between said antenna units and before the series capacitors for decoupling said antenna units. The decoupling circuit, by simply employing the decoupling capacitor, decouples the inductive coupling and capacitive coupling between the antenna units simultaneously. The method can be employed to decouple an RF transmit coil outside a magnetic body via the use of a decoupling capacitor.

摘要： A seat recliner comprises an inner toothed plate (2) having an inner ring gear (21), an outer toothed plate (3) having an outer ring gear, an eccentric wheel (4) and a wedge-shaped block (6). A shaft shoulder (22) is provided in the center of the inner toothed plate (2), and an axis central hole (32) is provided in the center of the outer toothed plate (3). The outer ring gear engages with the inner ring gear (21), and a radially eccentric area is formed between the shaft shoulder (22) and the axis central hole (32). The eccentric wheel (4) is disposed in the radially eccentric area, and appears entirely in the shape of an eccentric ring, and a planetary gear transmission mechanism with small difference between the number of teeth is constituted by the eccentric wheel (4), the inner toothed plate (2) and the outer toothed plate (3). The eccentric wheel (4) in the large-diameter segment of the radially eccentric area forms a clearance fit with the shaft shoulder (22) and the axis central hole (32). The wedge-shaped block (6) is disposed in the radially eccentric area, and clearances between the eccentric wheel (4) and the axis central hole (32) of the outer toothed plate (3) and between the engaged teeth are eliminated by the wedge-shaped block (6) and the eccentric wheel (4) under a circumferential force exerted by an elastomer (7). The seat recliner has extremely high and stable strength performance. A seat having the seat recliner is also provided.

摘要： A method for switching pages in interfaces includes obtaining an operational event on an interface, and triggering pages in a screen to move following the operational event; obtaining a sign corresponding to the moving page according to a mapping relationship between pages and signs; controlling the sign to move synchronously with the moving page; and obtaining the page to be settled in the screen according to the operational event. The above method and apparatus for switching pages in interfaces and computer storage medium trigger the pages in the screen to move along with operational events when the user operates events on the interfaces; and the signs corresponding to the pages would synchronously move with the moving pages. The signs dynamically indicate the page positions during the switch of the pages, therefore the intermediate status during the switch of the pages could be dynamically indicated, and the users' operational events on the interface is also dynamically fed back, which improves the flexibility in switching pages.
