    Abstract: Disclosed herein is a lighting system configured to obtain an indicator data of a RF spectrum signal generated at a number of times in an area. At each respective one of the number of times, apply one of a plurality of heurist algorithm coefficients to each indicator data from a receiver for the respective time, based on results of the applications of the coefficients to indicator data, generate an indicator data metric value for each of the indicator data for the respective time, and process the indicator data metric values to compute an output value. The lighting system is further configured to compare the output value at each of the plurality of times with a threshold, to detect one of an occupancy condition or a non-occupancy condition in the area and control the light source in response to the detected one of the occupancy condition or the non-occupancy condition in the area at each of the number of times.

    Abstract: Disclosed herein is a lighting system configured to obtain an indicator data of a RF signal generated at a number of times in an area. When each such time is a current time, the indicator data generated at the current time is compared with the indicator data generated at a preceding time to determine a rate of change, and the indicator data generated at the current time is compared with a baseline indicator data at an earlier time to generate a difference value. The lighting system is configured to determine an indicator data metric based on the rate of change and the difference value and compare the indicator data metric with one of a rising transition threshold or a falling transition threshold to detect one of an occupancy condition or a non-occupancy condition in the area.

    Abstract: The disclosure provides an example of a system including a radio frequency (RF) wireless communication network (network) including a plurality of nodes in an area and a computer coupled to the network. Each of the nodes includes a transmitter and a receiver. At plurality of times, each transmitter transmits RF spectrum signals (signals) and each receiver receives the signals and also generates an indicator data of a signal characteristic of the received signal propagated in the network. When each time among the plurality of times is a current time, the computer obtains the indicator data of the signal, determines a modification in the indicator data at the current time from the indicator data at a preceding time due to a movement of an occupant in the area and detect an occupancy condition in the area based on the modification in the indicator data and a parameter of a configuration of the network.

    Abstract: Disclosed herein is a lighting system including a detector, which is configure to obtain an indicator data of a RF signal. The detector compares the indicator data with a baseline indicator data to generate a difference value and determines a rate of change from the indicator data. The detector also determines a data metric based on the rate of change and the difference value and compares the data metric with a transition threshold to detect one of an occupancy condition or a non-occupancy condition in the area. The lighting system also includes a light source, which is controlled in response to the detected one of the occupancy condition or the non-occupancy condition in the area.
