    • For a radio communications system with time-divided frequencies, the synchronization between a base station and a mobile station is shifted as the mobile moves. The base station transmits symbol sequences with synchronization words to the mobile, which through this obtains a reference point in time. The mobile transmits to the base station symbol sequences with synchronization words, which in the mobile may be displaced in time relative to the reference point in time. The base station generates a reception point in time for the symbol sequences from the mobile by correlation and filtering. The reception point in time is compared with the reference point in time and upon a mutual deviation, a time deviation is generated for the base station. This time deviation is added to a previous time shift in the mobile. A new value for the time shift in the mobile is sent with an adjustment order and the mobile adjusts its transmission point in time relative to the reference point in time by means of the adjustment order. In order to increase the probability that the mobile detects the adjustment order, this order is repeated a number of times. If the reception point in time after this remains unchanged, a resynchronization is ordered, or as an alternative, a release of the connection. Disturbances to the radio connection due to deficient synchronization or frequently recurring resynchronization are reduced.
    • 对于具有时分频率的无线电通信系统,基站和移动台之间的同步随着移动移动而移动。 基站向移动台发送具有同步字的符号序列,通过这个获取参考点。 移动台向基站发送具有同步字的基站符号序列,移动台中的同步字可能在时间上相对于参考点在时间上移位。 基站通过相关和滤波从移动台生成符号序列的接收点。 将接收时间点与参考时间点进行比较,并且在相互偏离时,基站产生时间偏差。 这个时间偏差被添加到移动设备的之前的时间偏移。 通过调整顺序发送移动台中的时移的新值,移动台通过调整顺序调整其相对于参考点的时间点的传输点。 为了增加移动台检测到调整顺序的可能性,这个顺序被重复了多次。 如果在此之后的接收点保持不变,则重新同步被排序,或作为替代,释放连接。 由于同步不足或频繁重复同步而导致无线电连接的干扰减少。

    • A medical technical compression implant (1) for the surgical repair of damage to the spine, especially in the cervical region, includes two clamp jaws (3, 4), which are directed toward each other, are hook-shaped, are connected by a threaded spindle (2), and can be compressed while reducing the distance (B) between them. A wrench profile (9) for attaching a rotating tool in an interlocking manner is arranged at the threaded spindle (2) between two threaded sections (7, 8) with right-hand threads and left-hand threads, respectively. Both the clamp jaws (3, 4) have threaded nuts (5, 6), which are pivotably mounted from bodies, with diametrical threaded bores for screwing on the threaded sections (7, 8). The threaded nuts are mounted in cylindrical transverse bores of the clamp jaws (3, 4). The bore walls (21) are provided with diametrical openings (22, 23) for passing through the threaded sections (7, 8) of the threaded spindle (2). The threaded spindle (2) has, at both ends, an outwardly tapering cone (12, 13) each, which brings about pivoting of the clamp jaw (3, 4) around the axis of the transverse bore in the pulling direction, in cooperation with the inner edge or inner surface of the opening (22) designed as a radial bore.A manipulating device in the form of a special expanding forceps is provided for implantation.
    • 一种医用技术压缩植入物(1),用于手术修复对脊柱的损伤,特别是在颈部区域中,包括彼此指向钩形的两个夹爪(3,4),其通过 螺纹主轴(2),并且可以在减小它们之间的距离(B)的同时进行压缩。 用于以旋转方式连接旋转工具的扳手轮廓(9)分别在右螺纹和左旋螺纹的两个螺纹部分(7,8)之间的螺纹主轴(2)处布置。 夹爪(3,4)都具有螺纹螺母(5,6),螺母(5,6)可从主体枢转安装,并具有用于螺纹连接在螺纹部分(7,8)上的直径螺纹孔。 螺母安装在夹爪(3,4)的圆柱形横向孔中。 孔壁(21)设置有用于穿过螺纹心轴(2)的螺纹部分(7,8)的直径开口(22,23)。 螺纹主轴(2)在两端具有各自的向外锥形的锥体(12,13),这使得夹钳(3,4)在牵引方向上围绕横向孔的轴线枢转地协作 其中开口(22)的内边缘或内表面被设计为径向孔。 提供特殊扩张镊子形式的操纵装置用于植入。
