    • A method (10) and system (50) for using a biometrically enabled password can include an input device (58) capable of entering a password entry and a processor (56) coupled to the input device. The processor can monitor (16 or 26) a cadence such as monitoring a keystroke signature, store the cadence of the password entry, compare (28) the cadence of a subsequent password entry with the cadence of at least one previous password entry, establish (30) a stability metric with respect to the cadences compared, and require (32) both the password entry and the cadence once the cadence meets the stability metric. The processor can require only the password entry until the stability metric for the cadence is achieved. The processor can also determine (14) if the password entry is new and optionally require (18) only the password entry to enter the system if determined as new.
    • 用于使用生物测量使能密码的方法(10)和系统(50)可以包括能够输入密码条目的输入设备(58)和耦合到输入设备的处理器(56)。 处理器可以监视(16或26)节奏,例如监视击键签名,存储密码条目的节奏,比较(28)后续密码条目的节奏与至少一个先前的密码条目的节奏,建立( 30)相对于节奏的稳定性度量,并且一旦节奏达到稳定度量,则要求(32)密码输入和节奏。 处理器只需要密码输入,直到达到节奏的稳定度度量。 处理器还可以确定(14)如果密码条目是新的,并且可选地(18)仅当确定为新的密码条目才能进入系统。

    • The present invention can include a method for tuning grammar option weights of a phrase-based, automatic speech recognition (ASR) grammar, where the grammar option weights affect which entries within the grammar are matched to spoken utterances. The tuning can occur in an unsupervised fashion, meaning no special training session or manual transcription of data from an ASR session is needed. The method can include the step of selecting a phrase-based grammar to use in a communication session with a user wherein different phrase-based grammars can be selected for different users. Feedback of ASR phrase processing operations can be recorded during the communication session. Each ASR phrase processing operation can match a spoken utterance against at least one entry within the selected phrase-based grammar. At least one of the grammar option weights can be automatically adjusted based upon the feedback to improve accuracy of the phrase-based grammar.
    • 本发明可以包括一种用于调整基于短语的自动语音识别(ASR)语法的语法选项权重的方法,其中语法选项权重影响语法中哪个条目与语音话语相匹配。 调谐可以以无监督的方式发生,这意味着不需要特殊的训练会话或手动转录来自ASR会话的数据。 该方法可以包括选择基于短语的语法以在与用户的通信会话中使用的步骤,其中可以为不同的用户选择不同的基于短语的语法。 可以在通信会话期间记录ASR短语处理操作的反馈。 每个ASR短语处理操作可以将所说的话语与所选择的基于短语的语法中的至少一个条目相匹配。 可以基于反馈来自动调整至少一个语法选项权重,以提高基于短语的语法的准确性。

    • The present disclosure provides a method and device for detecting and repairing a channel anomaly of an active antenna, and the method includes: an operation state of a transmission channel or a reception channel is determined by analyzing in real time data of a feedback coupling channel or data of the reception channel, if the operation state is anomalous, an anomaly protection is performed and an alarm is reported; a level of the alarm and a reason causing the alarm are determined, if data of the transmission/reception channel are anomalous and the anomaly protection is performed, a current antenna beam forming parameter is stored and the antenna beam forming parameter is set to zero; after the alarm has been eliminated, a stored valid antenna beam forming parameter is set to a valid value; and if a transmission/reception analog channel operates anomalously and the anomaly protection is performed, the antenna beam forming parameter is re-acquired and an acquired valid antenna beam forming parameter is configured. The present disclosure can detect states of multiple transmission/reception channels of an active antenna without an extra calibration channel, thus reducing the design cost of a system.
    • 本公开提供了一种用于检测和修复有源天线的信道异常的方法和装置,并且所述方法包括:通过分析反馈耦合信道的实时数据来确定传输信道或接收信道的操作状态, 接收信道的数据,如果操作状态异常,则进行异常保护并报告报警; 如果发送/接收信道的数据异常并且执行了异常保护,则确定报警的级别和引起报警的原因,存储当前天线波束形成参数并将天线波束形成参数设置为零; 在消除了报警之后,将存储的有效天线波束形成参数设置为有效值; 并且如果发送/接收模拟信道异常操作并执行异常保护,则重新获取天线波束形成参数,并且配置获取的有效天线波束形成参数。 本公开可以检测有源天线的多个发送/接收信道的状态,而不需要额外的校准信道,从而降低系统的设计成本。
