Abstract: An article includes a solid circuit die on a first major surface of a substrate, wherein the solid circuit die includes an arrangement of contact pads, and wherein at least a portion of the contact pads in the arrangement of contact pads are at least partially exposed on the first major surface of the substrate to provide an arrangement of exposed contact pads; a guide layer including an arrangement of microchannels, wherein the guide layer contacts the first major surface of the substrate such that at least some microchannels in the arrangement of microchannels overlie the at least some exposed contact pads in the arrangement of exposed contact pads; and a conductive particle-containing liquid in at least some of the microchannels. Other articles and methods of manufacturing the articles are described.

Abstract: A system includes a negative pressure reusable respirator configured to be worn by a worker and to cover at least a mouth and a nose of the worker, a sensor configured to generate sensor data indicative of a characteristic of air within a work environment, and at least one computing device. The negative pressure reusable respirator includes at least one contaminant capture device configured to remove contaminants from air as the air is drawn through the contaminant capture device when the worker inhales. The at least one contaminant capture device is configured to be removable from the negative pressure reusable respirator. The at least one computing device configured to determine whether the at least one contaminant capture device is due for replacement, and perform one or more actions in response to determining the at least one contaminant capture device is due for replacement.

Abstract: A filter predicted capacity estimation system is presented that includes a parameter retriever that retrieves parameter information for an atmosphere around the filter. The system includes a parameter trend retriever that retrieves historical parameter indications from a database. The system also includes a real time capacity estimator that, based on the parameter information retrieved, and solves a set of controlling equations to generate an estimated capacity. The controlling equations are a set of mass and energy balance equations. The system also includes a parameter projection generator that, based on the historic parameter indications, generates a future parameter trend for the atmosphere and filter use. The system also includes a predicted capacity estimator that, based on the adsorption estimate, and based on the future parameter trend, generates a predicted capacity estimate. The system also includes a signal generator that generates a signal if either the estimated capacity or the predicted capacity estimate is above a threshold.
