    Abstract: Suppressing one or more frequency ranges of a signal prevents the occurrence of feedback in a voice data communications application. A system recognizes a frequency range in a signal where feedback occurs, or anticipates a frequency range where feedback is anticipated. The signal includes a signal the input system generates or that the output system renders. The system suppresses the signal in the frequency range by disregarding one or more sampling bits representing the frequency range, or by applying one or more filters to attenuate or eliminate the signal in the frequency range. The system may monitor the signal to identify feedback resulting in different or additional frequency ranges and suppress the signal in the different or additional frequency ranges to prevent feedback from occurring.

    Abstract translation: 抑制信号的一个或多个频率范围阻止语音数据通信应用中的反馈的发生。 系统识别发生反馈的信号中的频率范围，或者预期预期反馈的频率范围。 信号包括输入系统产生的信号或输出系统呈现的信号。 该系统通过忽略表示频率范围的一个或多个采样位，或通过施加一个或多个滤波器来衰减或消除频率范围内的信号来抑制频率范围内的信号。 该系统可以监视信号以识别导致不同或附加频率范围的反馈，并且抑制不同或附加频率范围内的信号以防止发生反馈。

    Abstract: Systems, methods, and/or techniques (“tools”) are described that sort speakers in a network-enabled conference. In some cases, this sorted list of speakers indicates which speaker is dominant. With this sorted list, a participant's communication device may provide context about the speakers. In some cases a participant's communication device has a display that presents real-time video of the speakers or other visual indicia, such as each or the most dominant speaker's name, picture, title, or location. These and other context about speakers may help participants better understand discussions in network-enabled conferences.

    Abstract: Architecture that facilitates the conveyance of a trust level when the caller makes a call, the trust level in dependence on the state of the caller system. The callee (call recipient) receives notification of the trust level and can use this information in the communication such as to request verification from the caller and/or initiate other modes of communication. A caller can authenticate the caller identity in different ways to a communication server. Based on that, the server can assign an appropriate server-verified trust level to the caller. Further, an unsecured phone controller can indicate a lower client-side defined trust level. The server verified and client-side trust levels are then sent to the callee, where the callee determines whether to allow caller access to one or more secured features based on the feature values and the trust level imposed by the callee to access those features.

    Abstract translation: 当调用者进行呼叫时，有助于传递信任级别的体系结构，信任级别取决于呼叫者系统的状态。 被叫方（呼叫接收方）接收到信任级别的通知，并且可以在通信中使用该信息，以便从呼叫者请求验证和/或启动其他通信模式。 呼叫者可以以不同的方式向通信服务器认证呼叫者身份。 基于此，服务器可以为呼叫者分配适当的服务器验证的信任级别。 此外，不安全的电话控制器可以指示较低的客户端定义的信任级别。 服务器验证和客户端信任级别然后被发送到被叫方，被叫方根据特征值和被叫方强制访问这些特征的信任级别确定是否允许主叫方访问一个或多个安全特征。

    Abstract: To reduce the power consumption of a wireless communication hardware device, power conservation scheduling algorithms can be implemented. Reoccurring events, including DTIM intervals and listen intervals can be scheduled as awake times. Similarly expected response intervals can be scheduled as awake times based on information, such as round trip time, that can be passed together with data to be transmitted. The wireless communication hardware device can be placed into a doze state unless it is transmitting data, or unless it is expecting a transmission during one of the scheduled awake times.

    Abstract translation: 为了降低无线通信硬件设备的功耗，可以实现节能调度算法。 重复事件（包括DTIM间隔和监听间隔）可以安排为唤醒时间。 类似地，期望的响应间隔可以基于可以与要发送的数据一起传递的信息（诸如往返时间）被调度为唤醒时间。 除非正在发送数据，否则无线通信硬件设备可以被置于打盹状态，或者除非在预定的唤醒时间之一期间期望传输。

    Abstract: A method and system for scanning in a wireless device having a wireless network interface card (NIC) is presented. The system has a scanning history table for storing scanning results and a scanning engine that adjusts the scanning period based upon a history of scanning results and commands the NIC to scan for available networks after the period has expired. The engine receives scan results from the NIC, stores the scan results in the scanning history table, determines a scanning period based upon a history of scan results, sets the scanning period, and commands the NIC to scan for available networks after the scanning period has expired. The engine is programmed to set the scanning period using an exponential function and to reset the scanning period to a default period if the scan results are different from a prior scan result or if a triggering event is received.

    Abstract: Physical presence of a mobile device in proximity to a physical meeting place can be recognized. Identifying information can be retrieved from the device, and it can be determined whether the identifying information correlates to identifying information for a profile in an invitee list for a current meeting at the meeting place. If the retrieved identifying information correlates to identifying information for the profile in the invitee list for the meeting at the meeting place, then the profile can be included as an attendee at the meeting (e.g., by including identifying information for the profile in an attendee list). The identifying information such as the attendee list may also be used to perform one or more additional acts, such as sending notifications, personalizing settings, etc.

    Abstract: Devices connected with a computer system are interrogated to detect whether they are configured and functioning. In an audio device implementation, a known audio sample is output to a loudspeaker. If the loudspeaker is properly configured and functional, an attached microphone will capture the sound corresponding to the audio sample generated by the loudspeaker. If sound corresponding to the audio sample is detected, an indication is provided to the user that the microphone and loudspeaker are operational. If no sound corresponding to the audio sample is detected, an indication is provided to the user that the loudspeaker is not enabled and additional configuration is required.
