Classification: CPC G | IPC G

Claim 11:
12. A system comprising:
a first positional sensing device configured to monitor a first area comprising:
a pulse generator for generating pulses;
a sensor for measuring data regarding a phase shift in modulated pulses from the pulse generator to one or more detected objects;
a first module for converting the data regarding the phase shift into (i) positional data and (ii) timestamp data for the one or more detected objects;

a server remote from the first positional sensing device comprising wherein the server is communicatively coupled to the first positional sensing device via a network, the server being configured to:
receive the (i) positional data and (ii) timestamp data for the one or more detected objects from the first positional sensing device; and
determine a trajectory for each of the one or more detected objects through the first area based on the (i) positional data and (ii) timestamp data;

wherein the server further comprises:
a first module configured to cluster the positional data into a plurality of clusters for each point of time indicated by the timestamp data, wherein each cluster represents a detected object of the one or more detected objects;
a second module configured to generate tracklets that track the position of each cluster of the plurality of clusters over each point of time indicated by the timestamp data; and
a third module configured to determine a trajectory for each of the one or more detected objects by connecting tracklets together that are associated with a same detected object.
