A surface-mountable glass-sealed light-emitting diode is provided. The camera module including an image sensor including a die mounted on a substrate, a housing coupled with the substrate to substantially enclose the die, and a dust trap substance adhered to the housing configured to capture and maintain at least one dust particle to decrease movement of dust particles within the housing, which decreases a number of blemishes in the captured image. The invention further relates to diagnostic and therapeutic methods useful for diagnosing and treating disorders related to these novel human secreted proteins. This minimizes the likelihood of creating airborne particles of the toxic drug during manufacturing, hence controlling and minimizing the exposure of manufacturing personnel to the hazardous substance. The tabs engage the landings as the switch device extends through the openings, and can be fastened together.
