Abstract: A distributed occupancy detection system includes plural networked node devices configured to be spatially distributed throughout a structure. Each node device includes an occupancy sensor that senses a presence characteristic indicative of an object being in a monitored area of the structure that is associated with the occupancy sensor. Each node device also includes one or more processors that determine a probability that the object is or was located in the structure based on the presence characteristic sensed by the occupancy sensor of a first node device and based on the presence characteristic sensed by the occupancy sensor of one or more neighboring node devices. The one or more processors determine whether the object is in the structure based on the probability.

Abstract: A networked light control system includes a wireless detection circuit configured to receive wireless signals emitted by marker devices associated with different lighting devices. The control system includes the lighting devices connected with each other in a wired lighting control network. The control system includes a controller configured to determine network addresses of the lighting devices in the wired lighting control network based on the wireless signals received from the marker devices. The control system includes the controller is configured to control operation of one or more of the lighting devices in the wired lighting control network using one or more of the network addresses that are determined based on the wireless signals received from the marker devices.

Abstract: A network system comprising node devices configured to be distributed in a structure and to self-form separate network groups; and a control commissioner device having a system coordinator device that is configured to communicatively couple with the node devices, the system coordinator device also configured to control formation of the separate network groups of different groups of the node devices by restricting which of the node devices can communicatively couple with different local coordinator devices, wherein the node devices of each of the separate network groups are configured to communicate with the local coordinator device associated with the network group.

Abstract: A lighting control system includes a monitoring assembly comprising a switch, an energy harvesting device, and radio circuitry. The switch is manually actuated to activate or deactivate network-controlled lamps. The energy harvesting device converts kinetic energy of the actuation of the switch into electric energy that powers the radio circuitry. The radio circuitry wirelessly broadcasts a radio control message to two or more networked controllers that control activation or deactivation of the lamps. The networked controllers communicate with each other and determine which of the networked controllers is a commander controller responsive to receiving the radio control message. The commander controller communicates a control message to other networked controllers to activate or deactivate the lamps based on the radio control message received from the monitoring assembly.
