Abstract: The present subject matter enables early or real-time detection of anomalies in electric networks. In various applications, the system detects anomalies, such as electricity theft, electricity surge, etc. It solves the difficult-to-detect problems in an electrical network, where anomalies like electricity theft or electrical surge may not be found until it has raised numerous concerns or complaints, or has created a significant impact on infrastructure functionality, service quality, or cost. In addition, the present subject matter decreases the requirement for large number of sensors and provides more cost effective and scalable solutions. The present subject matter provides a method for determining where a detected anomaly is occurring within an electrical network.

The mask body 12 has a sinus region 40 and a primary filtering region 44 and includes at least one nonwoven fibrous web, which web includes a layer of filter media. The sinus region 40 of the mask body 12 exhibits a resistance to airflow that is greater than the primary filtering region 44. This resistance to airflow is achieved through an alteration of the intrinsic structure of the plurality of nonwoven fibrous layers in the sinus region 40 without adding additional material to the mask body. The alteration of the intrinsic structure assists in preventing eyewear fogging.
