Timing device, system, and method for estimated time of arrival (ETA)

摘要

A timing device monitors an estimated time of arrival (ETA) for an object in a process of traversing a predetermined range of distance by computing the estimated time of arrival based on a time the object has spent completing at least one interval during the course of traversing the distance. The computation is invoked each time a signal is received by the timing device indicating the completion of an interval. The signal can be sent by a user of the device of by a transmitter placed near an end of the interval.
