    • A system and method for analog-to-digital conversion using digital pulse width modulation (PWM) is disclosed. The method and system according to the disclosed invention converts an analog input signal to a digital signal in pulse code modulated (PCM) form. The disclosed invention uses a feedback circuit to perform PWM of the analog input signal. The PWM signal is then decimated to obtain the digital signal in PCM form. The system according to the disclosed invention requires lower operating frequency and dissipates lesser power than prior art systems providing the same sampling frequency and resolution. The operation at a lower frequency is achieved by obtaining two samples from every pulse of the PWM signal; the first sample being obtained from the right duty ratio, and the second sample being obtained form the left duty ratio. Further, the disclosed invention has lesser implementation complexity and higher signal-to-noise ratio than prior art.
    • 公开了一种使用数字脉宽调制(PWM)进行模数转换的系统和方法。 根据所公开的发明的方法和系统将模拟输入信号转换成脉冲编码调制(PCM)形式的数字信号。 所公开的发明使用反馈电路来执行模拟输入信号的PWM。 然后抽取PWM信号以获得PCM形式的数字信号。 根据所公开的发明的系统需要更低的工作频率并且消耗比提供相同采样频率和分辨率的现有技术系统更小的功率。 通过从PWM信号的每个脉冲获得两个采样来实现较低频率的操作; 从正确的占空比获得第一个样品,并且从左占空比获得第二个样品。 此外,所公开的发明比现有技术具有较小的实现复杂度和更高的信噪比。

    • An affinity server estimates an affinity between two different time based media events (e.g., TV, radio, social media content stream), between a time based media event and a specific topic, or between two different topics, where the affinity score represents an intersection between the populations of social media users who have authored social media content items regarding the two different events and/or topics. The affinity score represents an estimation of the real world affinity between the real world population of people who have an interest in both time based media events, both topics, or in a time based media event and a topic. One possible threshold for including a social media user in a population may be based on a confidence score that indicates the confidence that one or more social media content items authored by the social media user are relevant to the topic or event in question.
    • 亲和度服务器估计在基于时间的媒体事件和特定话题之间的两个不同的基于时间的媒体事件(例如,TV,无线电,社交媒体内容流)之间或两个不同主题之间的亲和度,其中亲和度分数表示交集 在两个不同的事件和/或主题之间创作社交媒体内容的社交媒体用户之间。 亲和度分数表示对现实世界中有时间的媒体事件,两个主题或基于时间的媒体事件和主题感兴趣的人之间的真实世界关系的估计。 将社交媒体用户包括在群体中的一个可能的阈值可以基于置信度得分,该置信度得分指示由社交媒体用户创作的一个或多个社交媒体内容项目与所讨论的主题或事件相关的置信度。

    • An interface is provided that configures itself dynamically based on sensor information received from a sensor assembly or actuator information received from an actuator assembly. The interface may be configured to interoperate with sensor assemblies including analog transducers, smart transducers providing digital outputs and various actuators. The sensor information or the actuator information may include information for managing power consumption associated with the operation of the sensor or the actuator. Using the sensor information or the actuator information, a power management scheme may be implemented to reduce power consumption and extend the operational time of a module. The sensor information also includes information about the sensor signal generated by the sensor. The information about the sensor signal allows the module to interoperate with more diverse types of sensors.
