Abstract: The present relates to a system comprising a housing, a motor assembly, a printed circuit board (PCB) and a shaft. The motor assembly is located inside the housing. The motor assembly comprises a control for alternatively engaging and disengaging a functionality of the motor assembly. The printed circuit board (PCB) is located inside the housing and defines an aperture for receiving the shaft. The shaft extends through the aperture of the PCB. A first end of the shaft is adapted for actuating the control of the motor assembly. A second end of the shaft extends through an opening in the housing and is adapted for receiving an actuator.

Abstract: A system comprising a housing, a printed circuit board and a differential pressure sensor located inside the housing, and first and second male adaptors. The first and second male adaptors respectively extend through first and second openings in the housing. The first male adaptor comprises a proximal end configured to receive a first pipe, a distal end secured to the differential pressure sensor, and an internal fluid conduit for transmitting fluid received from the first pipe to the differential pressure sensor. The second male adaptor comprises a proximal end configured to receive a second pipe, a distal end secured to the differential pressure sensor, and an internal fluid conduit for transmitting fluid received from the second pipe to the differential pressure sensor. The differential pressure sensor is configured to determine a pressure differential between fluid received via the first male connector and fluid received via the second male connector.

Abstract: The protective eyewear assembly described comprises a frame having right and left portions defining respective right and left apertures and a central bridging portion, and a protective lens piece adapted to be mounted to the lens piece between the upper and lower edges of the frame. The lower edge of the frame has a retaining wall for retaining the lens therein while the upper edges of the frame and the lens piece have cooperating portions to secure the lens to the frame. The frame may be made of flexible plastic material to enable a snap-in engagement and a snap-out disengagement of the lens to and from the frame.
