  • Patent number: 8400294
    Abstract: Techniques are described that may be implemented in a portable electronic device to provide automatic detection of transit stops made by mass transit system vehicle in which a user of the device is a passenger. In an implementation, the portable electronic device includes an inertial sensor assembly to sense motion of the vehicle and generate a signal indicative of the vehicle motion. The inertial sensor assembly signal is used to detect the occurrence of a transit stop made by the vehicle. The portable electronic device can then display a prompt in response to detection of the transit stop. In embodiments, other measured data (e.g., elapsed time from a prior event, location information, direction, sound, and so on) may be used to verify the occurrence of the transit stop.
