Disclosed herein is system level occupancy counting in a lighting system configured to obtain an indicator data of a RF spectrum signal (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 heuristic algorithm coefficients to each indicator data of the signal, based on results of the application of the heuristic algorithm coefficients, generate an indicator data metric value for each of the indicator data for the respective time. The lighting system is also configured to process each of the indicator data metric value to compute a plurality of metric values for the respective time and combine the plurality of metric values to compute an output metric value for each of a plurality of probable number of occupants in the area for the respective time. The lighting system is further configured to determine an occupancy count in the area at the respective time based on the computed output metric value.

The present invention relates to a wireless power transmitter and method for detecting a RFID/NFC card. Disclosed in the present application is a wireless power receiver comprising: a power pickup unit configured to receive, in a power transfer phase, wireless power generated by magnetic coupling from a wireless power transmitter; and a communications/control unit configured to transfer, in a negotiation phase, a first end-of-power-transfer (EPT) packet to the wireless power transmitter for detecting an RFID/NFC card, and to detect the RFID/NFC card during a re-ping time secured on the basis of the first EPT packet, wherein the first EPT packet instructs requesting the removal of a power signal for a predetermined time. As the process for detecting communication cards, such as RFID or NFC, between the wireless power transmitter and receiver is clearly defined, such RFID/NFC cards can be protected against getting destroyed by the wireless power, and a stable wireless power transfer can be achieved.
