    • An orthodontic bracket is provided that includes a cover and a base, wherein the cover can be rotated over an arch wire slot in the base portion. The present bracket invention operates to close when a frangible portion is severed upon initiating rotation of the cover, such that the cover rotates about a hinge, which may include a pin or axle. In one embodiment of the invention, the pin or axle can be moved laterally and/or vertically after the frangible portion is severed. Preferably, the bracket is manufactured to form one piece, such as using an injection molding, machining, or casting process. The bracket offers economical advantages because additional subsequent assembly is not required to attach a cover to a base.
    • 提供了一种正畸托架,其包括盖和基座,其中所述盖可以在基部中的拱形线槽上旋转。 本发明的托架发明操作以在启动盖的旋转时切断易碎部分时闭合,使得盖围绕可以包括销或轴的铰链旋转。 在本发明的一个实施例中,销或轴可以在易碎部分断开之后横向和/或垂直地移动。 优选地,支架被制造成一体,例如使用注射成型,机械加工或铸造工艺。 该支架具有经济的优点,因为不需要额外的后续组装来将盖子附接到基座。

    • An inductive power transfer system comprises a primary unit (10), having a primary coil (12) and an electrical drive unit (14) which applies electrical drive signals to the primary coil so as to generate an electromagnetic field. The system also comprises at least one secondary device (30), separable from the primary unit and having a secondary coil (32) which couples with the field when the secondary device is in proximity to the primary unit. A control unit (16) causes a circuit including said primary coil to operate, during a measurement period, in an undriven resonating condition. In this condition the application of the drive signals to the primary coil by the electrical drive unit is suspended so that energy stored in the circuit decays over the course of the period. A decay measurement unit (18) takes one or more measures of such energy decay during the measurement period. In dependence upon said one or more energy decay measures, the control unit controls the electrical drive unit so as to restrict or stop inductive power transfer from the primary unit.
    • 感应电力传输系统包括具有初级线圈(12)和电驱动单元(14)的初级单元(10),其将电驱动信号施加到初级线圈以便产生电磁场。 该系统还包括至少一个次级装置(30),其可与主单元分离并且具有次级线圈(32),当次级装置接近初级装置时,它与该场耦合。 控制单元(16)使得包括所述初级线圈的电路在测量周期期间处于未驱动的谐振状态。 在这种情况下,通过电驱动单元将驱动信号施加到初级线圈被暂停,使得存储在电路中的能量在该周期的过程中衰减。 衰减测量单元(18)在测量期间采取这种能量衰减的一个或多个措施。 根据所述一个或多个能量衰减措施,控制单元控制电驱动单元以限制或停止从主单元的感应功率传递。

    • An improved edgewise orthodontic bracket is disclosed. In one embodiment, a bracket comprises a single pair of opposing T-shaped tie wings which define an archwire slot therebetween. Notches are provided on each of the mesial and distal sides of the center leg of each T-shaped tie wing for selectively receiving a ligating device. The notches are defined in the gingival/occlusal edges of the tie wings and comprise sloped portions that extend labially towards the archwire slot. Convex sidewall portions and convex floor portions are provided in the archwire slot adjacent to the notches. The body of the bracket is interconnected to a base that includes a continuous series of characters that serve as texturing to facilitate bonding of the bracket with a tooth. A discontinuous perimeter rail may be used at the edge of the base. A method for forming a bracket is also provided.
    • 公开了一种改进的沿边正畸托架。 在一个实施例中,支架包括在其间限定弓丝槽的单对相对的T形连接翼。 在每个T形连接翼的中心腿的每个中间和远侧上都设有切口,用于选择性地接收结扎装置。 切口被限定在连接翼的牙龈/咬合边缘中,并且包括倾斜的部分,其朝着弓丝槽口延伸。 凸出的侧壁部分和凸出的底部部分设置在与凹口相邻的弓丝槽中。 支架的主体与基座互连,底座包括连续的一系列字符,用作纹理,以便于支架与牙齿的粘合。 可以在基座的边缘使用不连续的周边轨道。 还提供了一种用于形成支架的方法。
