    • A method and apparatus is described for providing extended subscriber features, e.g., equal access, to otherwise non-conforming central offices of a telephone switching system. According to the invention, a register module is interposed between the subscriber line and an input of the central office for intercepting digits from the subscriber line intended for the central office and for receiving subscriber information from the central office identifying the subscriber line. The register module includes a memory having a plurality of address locations and a control circuit for analyzing the intercepted digits to determine whether processing of the subscriber call requires an extended subscriber feature. If so, the intercepted digits are processed to generate a coded signal, the coded signal including the address location where the stored digits and the subscriber information resides in the memory. The coded signal is then used by the marker in the central office to select an appropriate outgoing trunk to complete the subscriber call. An associated trunk module interposed between the switch element of the central office and the outgoing trunks receives the coded signal and in response thereto polls the register module to request transmission of the digits and the subscriber information. Upon receipt of this data, the trunk module outputs a signal to the selected trunk.
    • 描述了一种方法和装置,用于向电话交换系统的其他不合格的中心局提供扩展用户特征,例如相等的访问。 根据本发明,寄存器模块插在用户线和中心局的输入端之间,用于从用于中心局的用户线截取数字,并从中心局接收用户信息,用于识别用户线。 寄存器模块包括具有多个地址位置的存储器和用于分析被截取数字以确定用户呼叫的处理是否需要扩展用户特征的控制电路。 如果是,则截取的数字被处理以产生编码信号,编码信号包括存储的数字和订户信息驻留在存储器中的地址位置。 然后编码信号由中心局的标记使用,以选择适当的出行中继线来完成用户呼叫。 插入在中心局的交换单元与输出中继线之间的相关联的中继模块接收编码信号,响应于此,轮询寄存器模块以请求数字和用户信息的传输。 在接收到该数据后,中继线模块向所选择的中继线输出信号。

    • A solid pharmaceutical tablet having a predetermined dosage that can be divided into a plurality of sub-dosage units by applying a minimal amount of force to the tablet. The tablet comprises a solid body having a top surface, a bottom surface, an outer surface, and an inner surface. The inner surface defines an aperture having a shape corresponding to the shape of the tablet. The area of the aperture is at least 15% of the area of the tablet. Impressed within the top surface of the tablet are a first plurality of symmetrical score lines and impressed within the bottom surface of the tablet are a second plurality of symmetrical score lines. The score lines extend from the aperture to the outer surface of the tablet. Finally, each of the sub-dosage units has a dosage that is a fraction of the predetermined dosage of the tablet.
    • 一种具有预定剂量的固体药物片剂,其可以通过对片剂施加最小量的力而被分成多个次剂量单位。 片剂包括具有顶表面,底表面,外表面和内表面的固体。 内表面限定具有对应于片剂形状的形状的孔。 孔径的面积至少为片剂面积的15%。 在片剂的顶表面内印有第一组多个对称刻痕线,并且印在片剂的底表面内的是第二组多个对称刻痕线。 刻痕线从平板的孔径延伸到外表面。 最后,每个次剂量单位的剂量是片剂预定剂量的一部分。
