Abstract: An electronic device having an interior volume, the electronic device including a sealing mechanism to prevent ingress of water into the interior cavity. The sealing mechanism having a channel having a first opening at an external environment and a second opening that leads to the interior volume, a membrane that covers the second opening, the membrane being air permeable and water resistant such that the membrane allows air to pass and prevents passage of water up to an upper pressure threshold, a stopper mechanism, and a diaphragm comprising a surface arranged to receive an external water pressure and that is air and water impermeable, the diaphragm being coupled to the stopper mechanism that deflects in response to the water pressure such that the diaphragm actuates the stopper mechanism and seals off the channel from at the first opening preventing water pressure at the membrane from exceeding the upper pressure threshold.

Abstract: An electronic device having a pressure detection system is disclosed. The electronic device may include one or more elements designed to detect pressure exerted on the electronic device. In some embodiments, the electronic device includes a membrane and a detection mechanism, both of which bend in response to a pressure change at the membrane. The membrane may be electrically coupled with a circuit that detects the bending of the membrane and correlates the bending with a pressure change at the membrane. A can may be hermetically sealed with the membrane and surround the circuit to shield the circuit from liquid ingress. In some embodiments, a light transmitter and light receiver are used to detect the bending of the membrane. The light may reflect from the membrane at different angles, based upon a shape of the membrane, and contact the receiving element at different locations, corresponding to pressure change.

Abstract: An electronic device having a pressure sensor configured to determine pressure is disclosed. The electronic device includes an enclosure defining an internal volume. The enclosure may include a sidewall with an external opening that provides a vent for the internal components. To reduce the response of the pressure sensor (that is, the time required to detect a pressure change), the pressure sensor may secure with an internal wall of the enclosure. Further, the internal wall includes an opening defining an air pocket significantly smaller than the internal volume. When the pressure sensor is mounted to receive air via the air pocket, the pressure sensor may respond faster to pressure changes, as compared to receiving air circulating throughout the internal volume. This is due in part to an amount of airflow passing through the air pocket causing a greater pressure change throughout the air pocket as compared to the internal volume.
