Abstract: A media automation system controls the ability of local stations to automatically replace certain scheduled items. A show is identified as a restricted show, with respect to exclusion of content associated with at least one advertiser. Restriction rules, which are configured to prevent content associated with the at least one advertiser from being scheduled during the restricted show are obtained, and a master broadcast log is generated based on a broadcast schedule and the restriction rules. The local stations are prevented from successfully performing automated replacement of content during the restricted show by inserting a flag into metadata associated with the master broadcast log, the flag specifying a blackout attribute. Buffers can be established around restricted shows, so that spot breaks near restricted shows can also be restricted. A playout system can perform validation checks to ensure that advertisements from advertisers included in the list are not improperly scheduled.

Abstract: Apparatus, methods, and non-transitory computer readable media are described for detecting an operational safety condition within a container using a scanning sensor node deployed within the container and above a storage space within the container. For example, the method uses the scanning sensor node to sense if the container is in a closed state and monitors the storage space from above the storage space while the container is in the closed state. The method then has the scanning sensor node detecting a movement within the container based upon the monitoring of the storage space while in the closed state. Such a detected movement is indicative of the operational safety condition. The method then has the scanning sensor node transmitting an alert to a managing node over a wireless communication interface of the scanning sensor node, where the alert is associated with the operational safety condition within the container.
