  "textContent": "Disclosed is an approach for detecting that a state of an air-conditioning system in a building has changed and ultimately determining the air-conditioning system's operating pattern, which could help improve collection and/or use of crowdsourced data for an indoor positioning solution and thus lead to more accurate position estimates. According to the disclosed approach, while a mobile device is in the building, processor(s) may detect that the mobile device is stationary and may responsively (i) cause the mobile device to provide pressure data representing air pressure in the building while the mobile device is stationary and (ii) subsequently receive the pressure data from the mobile device. And based on the pressure data indicating a pressure change and representing air pressure in the building while the mobile device is stationary, processor(s) may detect that a state of the air-conditioning system in the building has changed.",
