    • Methods and apparatus for determining whether a media presentation device is in an on state or an off state are disclosed. A disclosed example method comprises determining contribution values from at least one of a signal measured from a sensing device or an output signal accessed from the presentation device, wherein the contribution values are indicative of a state of a presentation device. Summing, via a logic circuit, a first plurality of the contribution values corresponding to a first measurement cycle to generate a first intermediate fuzzy score for the first measurement cycle. Storing the first intermediate fuzzy score in a buffer including a plurality of intermediate fuzzy scores corresponding to respective measurement cycles. Combining, via the logic circuit, the intermediate fuzzy scores corresponding to a first time period to form a final fuzzy score. When the final fuzzy score satisfies a threshold, setting the state of the presentation device as on and enabling crediting of media presented by the presentation device.
    • 公开了用于确定媒体呈现设备是处于接通状态还是断开状态的方法和装置。 所公开的示例性方法包括从从感测设备测量的信号或从呈现设备访问的输出信号中的至少一个确定贡献值,其中贡献值指示呈现设备的状态。 通过逻辑电路对与第一测量周期对应的第一多个贡献值进行求和,以产生用于第一测量周期的第一中间模糊分数。 将第一中间模糊分数存储在包括对应于各个测量周期的多个中间模糊分数的缓冲器中。 通过逻辑电路组合对应于第一时间段的中间模糊分数以形成最终的模糊分数。 当最终模糊分数满足阈值时,将呈现设备的状态设置为开启状态,并使得呈现设备呈现的媒体的记入。
