    • A particular embodiment comprises:a semiconductor laser;a Mach-Zehnder type modulator;an analog adder for adding a modulation signal representing binary data with a DC bias voltage;a coupler for taking off a fraction of the modulated light signal;a photodiode;an amplifier;a bandpass filter tuned to a frequency equal to the binary data transmission rate;an amplifier;an amplitude detector;an amplifier; anda microprocessor associated with an analog-to-digital converter and with a digital-to-analog converter to modify the bias voltage so as to cause the amplitude of the spectrum line extracted by the filter and the amplitude detector to remain below a fixed threshold value. The invention is applicable to digital data transmissions.

    • A system, method, and apparatus for providing subscriber services to a mobile terminal are provided. The mobile switching centers (MSCs) transmit an MSC capabilities message which informs the Home Location Register (HLR) of the services the MSC supports. When a mobile terminal roams to a particular MSC, the HLR compares the subscriber profile and the MSC capabilities message to determine whether the MSC can support a particular subscriber service. Where the MSC cannot support a particular subscriber service, the HLR determines a comparable service which the MSC does support and modifies a copy of the subscriber profile to include the comparable service as a replacement for the subscriber service that is not supported.
    • 提供了一种用于向移动终端提供用户服务的系统,方法和装置。 移动交换中心(MSC)发送通知MSC支持的业务的归属位置寄存器(HLR)的MSC能力消息。 当移动终端漫游到特定MSC时,HLR比较用户简档和MSC能力消息,以确定MSC是否可以支持特定的用户业务。 在MSC不能支持特定用户业务的情况下,HLR确定MSC可支持并修改订户简档的副本的可比较的服务,以将可比较的服务包括为不支持的订户服务的替代。

    • An animal feces collection device includes a tube having distal and proximal end portions defining a path therebetween, a flap coupled to the proximal end portion, a mechanism for pivoting the flap between open and closed positions and a scooping section for collecting animal feces. The pivoting mechanism preferably includes a push button and an elongated arm pivotally connected to the flap and the lower portion of the push button. The scooping section is secured to the proximal end portion of the tube for directing feces rearwardly therethrough when the flap is raised to an open position. The device further includes a reservoir for receiving and storing collected feces and a mechanism for removably attaching the reservoir to the tube.
    • 动物粪便收集装置包括具有限定其间的路径的远端部分和近端部分的管,耦合到近端部分的瓣,用于在打开和关闭位置之间枢转瓣的机构和用于收集动物粪便的舀取部分。 枢转机构优选地包括按钮和可枢转地连接到翼片和按钮的下部的细长臂。 当翼片升高到打开位置时,舀取部分固定到管的近端部分,用于将粪便向后引导通过。 该装置还包括用于接收和存储收集的粪便的储存器和用于将储存器可移除地附接到管的机构。
