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 ring-shaped cushion for a hearing protector or audio headset. The cushion has a circumferential contact pad for sealing on a wearer's head and an attachment for sealing with an earmuff. The cushion further has a sound insulation tube that inwardly defines an inner space. The sound insulation tube extends between the contact pad and the attachment. The cushion has a ventilation passage that extends entirely through the cushion between an inlet opening in the contact pad and an area outside of the inner space. The cushion may further include one or more physiological sensors to monitor the health of a wearer.

Abstract: A method of fit testing includes providing a respirator donned by a wearer, providing an aerosol generator with a known aerosol output parameter, providing an enclosure that is physically supported around the wearer's head, where the aerosol generator delivers aerosol with the known aerosol output parameter that is at least partially contained within the enclosure around wearer's head, providing a sensor in electrical communication with a sensing element, where the sensor is operably connected to the respirator, and where the sensor is configured to monitor a particulate concentration parameter within the respirator, and providing a reader configured to communicate with the sensor, where the reader is configured to provide a respirator fit parameter based on a comparison of the particulate concentration parameter to the known aerosol output parameter.
