Abstract: A respirator is described that includes a mask body and at least one housing directly or indirectly coupled to the mask body. The at least one housing includes a pair of slots spaced apart from each other, a cantilevered snap feature disposed between the pair of slots, and a latch connected to the cantilevered snap feature. The respirator further includes at least one cover movably coupled to the at least one housing and including a pair of arms. Each of the pair of arms is disposed adjacent to a corresponding slot from the pair of slots and includes a wide end portion. The at least one cover further includes an elongate member extending between the pair of arms and connected to the wide end portion of each of the pair of arms. The elongate member is at least partially received through each of the pair of slots.

Abstract: Various embodiments of a light detection device and a method of using such device are disclosed. In one or more embodiments, the light detection device can include a housing including a top surface and a bottom surface, where the housing extends along a housing axis between the top surface and the bottom surface; and a support member connected to the housing and adapted to be selectively moved from a closed position to an open position. The support member is further adapted to maintain the light detection device in an upright position when the bottom surface and the support member are in contact with a working surface and the support member is in the open position.

Abstract: Various embodiments of a light detection device and a method of using the device are disclosed. In one or more embodiments, the light detection device can include a housing that extends along a housing axis between top and bottom surfaces. The device can also include a port that is adapted to receive a sample, and a door connected to the housing. The door can include an actuator portion adapted to selectively move the door between a closed position and an open position, and a cover portion connected to the actuator portion and adapted to close the port when the door is in the closed position and open the port when the door is in the open position to allow external access to the port.
