Abstract:
1. A detection method, comprising: gathering data indicating whether an unmodified moving object has passed a defined point using a sensor coupled to a computing device placed in a position to observe the defined point and to observe an event indicating that the moving object has passed the defined point, the computing device being modified or adapted for placement in the position to observe the event; transforming the data using the computing device from a first form into a second form in which the data can be evaluated as a time series; evaluating selected data points of the time series of data in real time using the computing device to establish at least one learned statistic that is updated continuously at a defined rate and that represents a set of ambient conditions around the defined point over one or more time spans of undisturbed data, the time spans being selected in real time during said gathering data and being within a time period of said gathering data; detecting that the event has occurred in real time using the computing device by determining that the time series of data has deviated from the learned statistic in a specified way by more than a defined threshold, the defined threshold determined, at least in part, using the learned statistic, the deviation of the learned statistic in the specified way indicating that the moving object has moved through a detection field of the sensor and has thus passed the defined point; and calculating and recording or displaying one or both of event count or event timing information based on said detecting.
