    Abstract: An electronic device may include one or more low-noise pressure sensors for measuring air pressure. The electronic device may include wireless communications circuitry for communicating with external devices also having pressure sensors. Pressure data gathered by an external device may be used as reference pressure data for the electronic device. For example, if both devices are located in the same building, both pressure sensors will detect similar pressure fluctuations due to doors opening and closing and temperature-control systems turning on and off. By subtracting the reference pressure data from the pressure data gathered by the electronic device, calibrated pressure data may be obtained and may be used to reliably detect vertical displacement changes of the electronic device. In other scenarios, the pressure data may be compared with the reference pressure data to determine whether the two devices are in the same MOM.

    Abstract translation: 电子设备可以包括用于测量空气压力的一个或多个低噪声压力传感器。 电子设备可以包括用于与也具有压力传感器的外部设备通信的无线通信电路。 由外部设备收集的压力数据可以用作电子设备的参考压力数据。 例如，如果两个设备位于相同的建筑物中，则两个压力传感器将检测到门打开和关闭以及温度控制系统打开和关闭时出现的类似压力波动。 通过从由电子设备收集的压力数据中减去参考压力数据，可以获得校准的压力数据，并且可以用于可靠地检测电子设备的垂直位移变化。 在其他情况下，可以将压力数据与参考压力数据进行比较，以确定两个装置是否处于相同的MOM。
