Abstract: A computer-driven apparatus coupled to a network receives data from metadata sources and consumers' display devices. From the sources, the apparatus collects metadata concerning characteristics of a given item of host video and a proposed class of advertisements for web delivery proximate or embedded in the given item. The apparatus continually monitors actual delivery of the given item by receiving transmissions from consumers' display devices. The apparatus develops initial forecasting inputs based on historical data from similar host videos, and then adjusts the forecasting inputs based on the actual deliveries. These forecasting inputs are used to compute an interim supply of advertising opportunities associated with the given item, which is reduced by relevant factors to provide a net available supply forecast. The apparatus provides a human-readable display of information including the net available supply forecast.

Abstract: Disclosed herein are passive triggering mechanisms for activation of pyrotechnic features within electrical switching devices, such as contactor devices and fuse devices. The activation of the pyrotechnic features is configured to change the configuration of the internal components of the switching device and prevent current flow through the device. In some embodiments, the triggering mechanisms comprise features that respond to a magnetic field, such as a reed switch. In some embodiments, threshold strength of a magnetic field needed to trigger the passive triggering mechanism, which corresponds to a threshold level of current running through the switching devices indicating a dangerous overcurrent, can be adjusted based upon the distance between the passive triggering mechanism and a portion of the device such as a power terminal or feature connected to a power terminal.
