摘要： A system for generation of processed data for use in third party relationship monitoring is described. The system includes a communications system providing services to subscribing users. The communications system includes a rules database for storing rules, a data mining agent for mining and storing data relating to subscribing users, a content generator for generating protected user-related data from the mined data and communicating said user-related data over an interface, and a rights object generator for generating a usage rights object in response to the rules stored in the rules database and communicating said usage rights object over the interface. A tamper proof processing arrangement is connected to the interface. The tamper proof processing arrangement receives the user-related data and usage rights object from the communications system and processes the user-related data under control of the usage rights object. A signal output generator generates an output signal representative of processed data received from the processing arrangement.

摘要： An IMS-enabled control channel for an IPTV service is provided by receiving at a Serving Call/State Control Function (S-CSCF) a Session Initiation Protocol (SIP) REGISTER message, the SIP REGISTER message identifying the originating user, receiving at the originating user a response from the S-CSCF indicating that the originating user has been authorised, and sending a SIP INVITE message from the S-CSCF to establish an open channel connection with a selected IPTV Application Server (AS). This open channel connection can then be used for the transmission of control messages, such as for starting play, starting recording, stopping play, etc., between the STB and the IPTV applications server, as well as for the delivery of personalized content, such as advertisements, voting responses, personalized voting triggers and targeted interactive events. By maintaining an open control channel with the IPTV AS, this offers a substantial reduction in the setup delay times for different applications.

摘要： A means by which a list of service options may be used as capability configuration parameters to specify a card application toolkit call setup command, such as from R-UIM applications, is provided. For example, when the R-UIM application sends a call setup command to a mobile communication station, the R-UIM application may also send a list of service options that may be used by the mobile communication station to negotiate with the network. During the service negotiation process of setting up the call, the mobile communication station will only use or accept a service option that is in the service option list.

摘要： A circuit for measuring signal output of a transducer includes an amplifier having a differential input and a single ended output referenced to a fixed potential. One transducer terminal is coupled through a source follower to an input terminal of the differential input and the other transducer terminal is coupled through a source follower and a resistive element to the other input terminal of the differential input whereby the transducer terminals are isolated from the fixed potential. A voltage to current converter converts the voltage at the single ended output to an output current that is applied to an input branch of a current mirror. A first output branch of the current mirror supplies a current equal to the converter output current to one terminal of the differential input. A second output branch of the current mirror supplies a current equal to the converter output current to the other terminal of the differential input. A third output branch of the current mirror supplies a multiple of the converter output current to a resistive element having a terminal connected to the fixed potential.

摘要： In a radio telecommunication system, the performance of a mobile unit can be significantly improved during a hand-over procedure by reusing existing security associations that correspond to the mobile unit. By reusing existing security associations, a mobile unit can begin secure communications immediately following the hand-over. Otherwise, and in accordance with conventional practice, the mobile unit will have to undertake the time consuming task of renegotiating the required security associations, before it can begin transmitting and receiving secure communications.

摘要： A transmitter within a line driver circuit is configured to supply data pulses over existing residential wiring. The transmitter is implemented in a CMOS integrated circuit. The transmitter comprises three stages: a front-end digital/analog convertor (DAC), an intermediate DAC, and a current amplifier. The first stage dictates whether the output signal is in high power mode or low power mode. The intermediate DAC, as the second stage, controls the waveform shape and tunes the edge rate, thereby outputting a positive current signal and a negative current signal. The final stage amplifies these current signals to yield current signals having a desired waveform shape, power mode, and edge rate.

摘要： The present invention provides a flexible fuel compensation system for determining the percent alcohol content of fuel in a flexible fueled vehicle at the instance of fueling and in an open loop operating mode. According to the invention, two estimated percent alcohol content values are calculated based on the old fuel mixture's alcohol content and two fueling possibilities. A first value is calculated for the possibility that E85 fuel was added to the tank and a second value is calculated for the possibility that E0 fuel was added to the tank. If the inferred ethanol content increases above a positive threshold during closed loop operation, the system assumes that E85 fuel has been added to the tank. Conversely, if the inferred ethanol content decreases below a negative threshold, the system assumes that E0 fuel was added to the tank. Accordingly, if the vehicle is shut down before a more accurate ethanol content determination is complete, the inferred ethanol content follows either the first or second estimated alcohol content value until the system reaches a closed loop operating condition.

摘要翻译： 本发明提供一种灵活的燃料补偿系统，用于在燃料加注和开环操作模式的情况下确定柔性燃料车辆中的燃料百分比。 根据本发明，基于旧燃料混合物的酒精含量和两种加油可能性来计算两个估计的醇含量百分比值。 对于将E85燃料添加到罐中的可能性计算第一个值，并计算第二个值，以便将E0燃料添加到罐中。 如果推断的乙醇含量在闭环操作期间增加到高于正阈值，则系统假定已将E85燃料添加到罐中。 相反，如果推断的乙醇含量降低到负阈值以下，则系统假设将E0燃料加入到罐中。 因此，如果车辆在更准确的乙醇含量测定完成之前被关闭，则所推断的乙醇含量遵循第一或第二估计的醇含量值，直到系统达到闭环操作状态。
