摘要： A vented EMA may have a vent that allows gas to pass from into and out of the vented EMA, while preventing liquid from passing into and out of the vented EMA. The vented EMA may have a desiccant material inside the vented EMA that absorbs condensation from within the vented EMA. A vented EMA may also have an air flow path that conducts gas into and out of the vent during operation. As a result, the pressure inside the vented EMA may equalize with the pressure outside the vented EMA, but the deleterious ingress of liquids may be ameliorated.
