Claim:
1. A non-transitory computer readable storage medium having a set of computer executable instructions that, when executed by a handheld communication device cause the handheld communication device to: sense acoustic signals during entry of a user into a vehicle, the sensed acoustic signals including ambient noise and desired noise; filter the ambient noise from the desired noise to identify a filtered signal pattern; activate operational status detection hardware in the handheld communication device when the filtered signal pattern matches a stored signal pattern; detect operational data during operation of the vehicle using the activated operational status detection hardware; receive vehicle characteristic information associated with at least one feature of the vehicle; identify sensing parameters associated with the received vehicle characteristic information; compare the detected operational data to the identified sensing parameters to determine the operational status of the vehicle; and where the defected operational data is determined to indicate that the vehicle is idling, measure an idling time corresponding to duration of vehicle idling; compare the measured idling time to an idling time threshold; and generate an alert signal when the measured idling time exceeds the idling time threshold.
