Disclosed herein are systems and methods for minimizing the risk of transmission of SARS-CoV-2 and/or other infectious diseases between individuals in close proximity to one another. The systems described herein may comprise a substantially transparent shield component, a chamber component, and a suctioning component. The systems and associated methods of the present disclosure are intended to remove any SARS-CoV-2 virus and/or other infectious agents that may be travelling within aerosols.

Disclosed herein are protective apparatuses, and associated systems, for minimizing the risk of transmission of SARS-CoV-2 and/or other infectious diseases between individuals in close proximity to one another including, for example, transmission through droplets projecting from the mouth or nasal region of an infected individual. Said apparatuses may comprise a substantially transparent shield component and a handle component comprising a connecting aspect. The protective apparatuses may comprise light emitting diodes and associated control means. The protective apparatuses of the present disclosure may further comprise a camera communicatively connected to a display screen.

A facial shield for a protective headgear system includes a polymeric sheet having an upper portion configured to be coupled to a support and a lower portion having a lower extremity, wherein the upper portion includes a first hole, a second hole, and a third hole, each one of the first, second, and third holes laterally spaced from the other two of the first, second, and third holes, and the first hole including a first section having a first hole gap and a second section laterally adjacent the first section and having a second hole gap, wherein the first hole gap of the first hole is greater than or equal to the maximum vertical dimension of a first hook of the support, and wherein the second hole gap of the first hole is greater than a vertical base thickness of a base of the first hook and is less than the maximum vertical dimension of the first hook.

Service for a machine such as a laboratory instrument can be facilitated by capture of images showing the field of view of a user of the machine, and modification of those images to remove confidential information. Modified images can then be provided to service technicians so that the service technicians can have visual information that would allow them to more effectively communicate and interact with the machines' users.

The present invention relates to optionally polymerizable mesogen compounds that include a polyvalent non-mesogenic core X to which is bonded three or four separate extensions, where each extension independently includes, in sequence, a linking group -L-, and a mesogen group -[Mesogen]. The mesogen compounds are represented by the following Formula (I), With reference to Formula (I), v is 3 or 4; t is 0 or 1; at least one Mesogen includes at least four cyclic groups; each -L- independently has an average chain length of at least 15 bonds; and at least one -L- has an average chain length of at least 25. Also described are liquid crystal compositions that include such mesogen compounds, and optical elements that include such mesogen compounds.

A welding helmet (1) has a protective shield (2) and a first swivel mechanism (10) that pivotally connects the protective shield with a head suspension system (6) for swiveling about a swivel axis. The first swivel mechanism enables the protective shield and the head suspension system to be swiveled between a lowered position, in which the protective shield covers a wearer's face, and an upraised position, in which the protective shield uncovers the wearer's face. The first swivel mechanism (10) has a recess (16a) and a retainer (17a) for engaging with the recess. The retainer and the recess are arranged to engage with each other in the upraised position, and to remain disengaged in the lowered position and between the lowered position and the upraised position.

An improved system and method for an eye patch can comprise a patch and a pad. The patch can be substantially flat and flexible. Furthermore, the patch can comprise a bottom surface, a top surface, and a concave edge. The bottom surface can comprise an adhesive capable of temporarily attaching to a skin. The concave edge can be on one side of the patch. Additionally, the concave edge can substantially match the anatomical curve of a human's eye socket. The pad can be a raised portion on the patch that can be capable of pushing upper natural eyelashes upward when a client closes her eyes. The pad can be attachable along the concave edge.
