Abstract: Aspects of the subject technology relate to a device including a pressure sensor to measure a pressure level in a port cavity. A port allows equalization of air pressure between the port cavity and an outside environment. A vent port within the port cavity allows equalization of air pressure between the port cavity and an internal volume of a housing of the device. A tool is used to activate a heat-generating component of the device while the port is obstructed for a predetermined time duration to enable detecting a sealing efficacy of the housing.

Abstract: Aspects of the subject technology relate to an apparatus including one or more transducers, and a pathway for drying the one or more transducers via removal of water from vicinities of the transducers. The pathway includes a tubular structure, and the one or more transducers are disposed at a first opening of the tubular structure. The pathway is to facilitate removal of water via capillary-induced pressure gradient created by a capillary-dense material disposed at a second opening of the tubular structure at a distance from the transducers.

Abstract: According to some aspects of the subject technology, an apparatus includes a first electrode, a second electrode and a dielectric membrane disposed between the first electrode and the second electrode. The first electrode and the second electrode include a number of pores within a region of an input port of the apparatus. The first electrode, the second electrode and the dielectric membrane form a capacitor that is configured to enable detection of occlusion of the input port by water.
