    • A method and apparatus that generates a spread spectrum signal in a printer power supply unit is disclosed. The method may include receiving an enable signal to power on the printer power supply unit, generating an initial power signal for the printer power supply unit based on the signal received from the power supply controller, the initial power signal being generated in a predetermined frequency range around a predetermined center frequency value, powering on the printer power supply unit using the generated initial power signal, repeatedly updating the initial power signal, wherein the updated power signal has a frequency value in the predetermined frequency range and the predetermined center frequency value is maintained, and powering the printer power supply unit using the updated power signal.
    • 公开了一种在打印机电源单元中产生扩频信号的方法和装置。 该方法可以包括接收使能信号以对打印机电源单元供电,基于从电源控制器接收的信号产生用于打印机电源单元的初始功率信号,初始功率信号在预定频率范围内产生 围绕预定的中心频率值,使用所产生的初始功率信号对打印机电源单元供电,重复更新初始功率信号,其中更新的功率信号具有预定频率范围内的频率值并且保持预定的中心频率值 ,并使用更新的电源信号为打印机电源单元供电。

    • A system and method for disseminating information concerning, for example, conditions affecting travel routes personalizes information in accordance with individual users or customers by building filters for attributes of the information from attributes of interest to each user, such as nodes of a travel route, which are registered with the system by the user or customer. The information is filtered by the filters constructed from the attributes to form a list of user identifications of users that have registered an attribute of interest which is included in the information provided to the system. Messages are retrieved from storage and communicated to users in accordance with the list of user identifications either automatically over one or more communication media also registered by each user or on a call-in inquiry basis. In the latter case and for modification or additions to registered user information and attributes of interest, the system and method provide for an active automated dialog with the user. Messages may include user-specified nomenclature for attributes or collections thereof.
    • 用于传播关于例如影响旅行路线的条件的信息的系统和方法根据个人用户或客户个性化信息,通过针对每个用户(例如旅行路线的节点)为每个用户构建信息的属性的属性构建过滤器,其中 由用户或客户在系统中注册。 信息被由属性构成的过滤器过滤,以形成已经注册了提供给系统的信息中包含的感兴趣属性的用户的用户标识列表。 消息从存储器检索并且根据用户标识的列表自动地通过也由每个用户注册的一个或多个通信媒体或在呼入询问基础上传送给用户。 在后一种情况下,对于注册用户信息和感兴趣的属性进行修改或添加,系统和方法提供与用户的主动自动化对话。 消息可以包括用户指定的属性或其集合的命名。
