    • 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 method and system for providing alternative prepaid service when a serving Packet Data Service Node (PDSN) does not support prepaid or at least the type of prepaid (duration-based or volume-based) the user has subscribed to. The serving PDSN sends an access request to a Home Authorization, Authentication & Accounting Prepaid Server (HAAA/PPS) with an indication of its capability to support prepaid service and to terminate sessions based on requests from remote nodes. When the serving PDSN is neither capable of prepaid service, nor does it support session termination by a remote node, the HAAA/PPS determines that a prepaid session is allowed and supported in combination with a Home Agent (HA) for duration-based prepaid service. When the PDSN is not prepaid capable but supports session termination capability, the HAAA/PPS determines that any type of prepaid service can be allowed and supported by the HAAA/PPS in combination with the HA.
    • 一种用于在服务分组数据业务节点(PDSN)不支持预付费或者至少是用户已订阅的预付费类型(基于持续时间或基于音量)的替代预付费服务的方法和系统。 服务PDSN向归属授权,认证和会计预付服务器(HAAA / PPS)发送访问请求,其指示其支持预付费服务的能力并且基于来自远程节点的请求终止会话。 当服务的PDSN既不能预付费,也不支持远程节点的会话终止时,HAAA / PPS确定预约会话被允许并与家庭代理(HA)结合支持,用于基于持续时间的预付费业务 。 当PDSN不具有预付能力但支持会话终止能力时,HAAA / PPS确定HAAA / PPS与HA结合可以允许和支持任何类型的预付费业务。

    • 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。
