Abstract:
A method of tracking a service queue using a single-point signal monitor in which at least one customer carries a wireless device may include: receiving a received signal strength from the wireless device as a trace; identify first segments of the trace containing mostly positive sloped received signal strength; identify second segments of the trace containing mostly negative sloped received signal; extract attributes from the first and second segments as child variables for two parent nodes in a Bayesian Network in which the two parent nodes respectively model a beginning of service and a leaving period for a service queue; and inputting the extracted attributes into Bayesian Network; and determining a beginning of service and leaving period using the Bayesian Network. The method may also include determining critical time points in a trace using a K-L divergence technique.

Claim (Index 7):
A method for tracking service queues, comprising:\n receiving, by a first antenna, wireless signals from a plurality of mobile wireless devices, each wireless device representing a subject entering, being serviced in or leaving a service queue; measuring, by a receiving circuit coupled to the first antenna, a signal strength amplitude of the received wireless signals from the first antenna; receiving, by a computing device coupled to the receiving circuit, a trace comprising a plurality of received wireless signal strength amplitudes from a selected one of the plurality of mobile wireless devices in a temporal order from a time the selected mobile wireless device enters a receivable range of the first antenna to a time the selected mobile wireless device exits the receivable range, determining, by the computing device, a slope of the trace; identifying, by the computing device, first segments of the trace containing a mostly positive sloped received signal strength; identifying, by the computing device, second segments of the trace containing mostly negative sloped received signal; extracting, by the computing device, attributes from the first and second segments; and by the computing device, inputting the extracted attributes in a Bayesian Network model to compute a beginning of service and a leaving period of the service queue, wherein the Bayesian Network model comprises two parent nodes, each respectively modeling a beginning of service and a leaving period of a service queue.
