Abstract: A protective headcover system includes a support configured to engage the head of a user, a cover configured to substantially cover the head of the user while leaving the ears of the user uncovered, the cover including a substantially transparent facial shield and a sheet sealingly coupled to the facial shield, the sheet including an elongate projection inward from or including a perimeter of the sheet, and a first dynamic hook coupled to the support and configured to displaceably engage the elongate projection of the sheet.

Abstract: A system includes a support configured to be carried by the head of a user, a facial shield configured to be coupled to the support such that the facial shield is maintained anterior to the face of the user, the facial shield having substantial clarity for viewing therethrough, the facial shield further including an outer surface and an inner surface, an emitted-light source configured to be carried between the facial shield and the user and configured to provide a light beam that is able to at least partially radiate through the facial shield, and a flexible elongate opaque sheet having a first end coupled to the emitted-light source and a free second end configured to maintain contact with the inner surface of the facial shield as the light beam is angularly adjusted over a working adjustment angle range.

Abstract: A protective headgear system includes a cover including a substantially transparent facial shield, a sheet sealingly coupled to the facial shield around the cover's perimeter, the sheet including a substantially anterior portion including a first sheet material configured to act as a substantial barrier to the passage of air, and including a substantially posterior portion including a second sheet material configured to filter contaminants from air, and one or more seams between the first sheet material and the second sheet material, a flow restrictor configured to significantly create a flow barrier between the cover and the neck of a user for providing an interior volume, an air mover configured to draw some of the external air into the interior volume, a filter coupled to the cover, and one or more flow directors configured to direct internal air, including at least some exhaled air, toward the second sheet material.

Abstract: A system for improving efficiency in a medical facility includes one or more sensors configured to wirelessly obtain information from a medical procedure area and output a first signal related to the obtained information, a processor configured to survey the first signal and identify one or more descriptors in the signal, and an output configured to describe one or more changes related to operation of the medical procedure area based at least in part on the one or more descriptors.

Abstract: A system for tracking the source of pathogens with a variable response and mitigation method utilizing a combination of UV, filtration, fans, communications and a control system. The control system monitors sensors that are indicative of pathogen propagation creating triggers and thresholds for a known measured response. The UV air treatment systems can generally include one or more UV air treatment fixtures as well as systems and methods for installing, operating, and maintaining the one or more UV air treatment fixtures. Some aspect emphasize features and configurations related to installation, operation, and maintenance of individual UV air treatment fixtures, while other aspects emphasize features and configurations related to coordination of multiple air treatment systems including data collection and control.

Abstract: A protective headgear system includes a support configured to engage the head of a user, a facial shield having an upper portion coupled to the support and a lower portion having a lower extremity, a flexible sheet coupled to the facial shield, a base carried by the support, a first microphone carried below the lower extremity of the facial shield and preferentially oriented away from the user, a second microphone carried by the base and preferentially oriented toward the user, a first audio generator capable of being sensed by at least one ear of the user, and a second audio generator including a loudspeaker carried by the base such that the loudspeaker is located below the lower extremity of the facial shield and is oriented for preferential sound energy delivery generally away from the user.
