Generating an atmospheric model using one or more pressure-sensing mobile devices

摘要

A mobile device comprising a pressure sensor for collecting pressure data, a position-determining subsystem for generating location data including altitude data, and a processor operatively coupled to a memory to generate an atmospheric model based on the pressure data and the location data. In one implementation, the processor is configured to determine an Above Mean Sea Level (AMSL) altitude using a position-determining subsystem, determine a pressure altitude using the pressure sensor, calculate a difference between the pressure altitude and the AMSL altitude, and calculate a temperature at sea level based on the AMSL altitude and pressure altitude. In one implementation, the processor performs a linear regression on an equation AMSL altitude=offset+ScaleFactor*PressureAltitude to solve for the offset and the ScaleFactor, and then estimates the temperature at sea level as 1-ScaleFactor=(T−15)/3. The model may be used to estimate ambient air temperature or weather conditions.

1. A computer processor-implemented method for delivering content to a handheld mobile device, the method comprising:
receiving pressure data and location data collected at each of a plurality of locations in a defined area remote to said processor by one or more handheld mobile devices, the handheld mobile devices being different to said processor and being remotely located relative to said processor and each having a pressure sensor and a position-determining subsystem, the location data including altitude data; determining a current location of a first of the one or more handheld mobile devices in the defined area; generating localized atmospheric conditions using the received data, and one or more of ambient temperature, pressure, and weather conditions from an atmospheric model at the determined current location of the first of the one or more handheld mobile devices, the atmospheric model based on the received pressure data and location data, the determined current location being remote to said processor; using the generated localized atmospheric conditions to determine content data relevant to the defined area, the content data being data other than said localized atmosphere conditions; and transmitting the determined content data to the first of the one or more mobile devices in the defined area for display on the handheld mobile device, the content data associated with one or more of the ambient temperature, the pressure and the weather at the determined current location.
