Abstract: A lighting system includes lighting devices and an update manager. The lighting devices include various hardware versions and/or functionalities. The lighting devices are queried to determine existing hardware versions and/or functionalities. The query is sent via a wireless mesh network of the lighting system. An Over-The-Air (OTA) update includes multiple different lighting device programming images, where each image corresponds to one of the existing hardware versions and/or functionalities. The OTA update is delivered via point-to-point connections between the update manager and some number of lighting devices and/or between the lighting devices. Upon receipt, individual lighting devices determine whether a lighting device programming image is needed and/or which of the lighting device programming images is appropriate.

Abstract: The disclosure provides examples of systems and methods for determining locations of a number of radio frequency-enabled devices such as mobile devices and radio frequency-equipped beacons/luminaires within an indoor location. The radio frequency-enabled devices may be part of an indoor positioning system and/or content delivery system. The examples describe obtaining an angle of arrival (AoA) of the signals received by the respective radio frequency-enabled devices. The AOA data is used to identify the relative positions of the radio frequency-enabled devices as the mobile device moves about the indoor location. Upon comparing AOA measurements of the collected data related to a map of the location, the system may generate a data structure that may be presented graphically as a map of positions of the devices at the location. The described examples may enable a rapid commissioning process with respect to the radio frequency-enabled devices in a network.

Abstract: An example radio frequency (RF) positioning node system calculates a respective distance between an uncommissioned RF positioning node to each of neighboring commissioned RF positioning nodes based on a respective received signal strength indicator (RSSI) measurement. Based on the calculated respective distance to each of the neighboring commissioned RF positioning nodes and a set of commissioned location coordinates of each of the neighboring commissioned RF positioning nodes, the RF positioning node system estimates a set of uncommissioned location coordinates of the uncommissioned RF positioning node. The RF positioning node system determines a best fit assignment of the set of uncommissioned location coordinates of uncommissioned RF positioning nodes in an uncommissioned RF positioning node list to the set of commissioned location coordinates of non-operational commissioned RF positioning nodes in a non-operational RF positioning node list to adjust an RF positioning node map for each of the non-operational commissioned RF positioning nodes.

Abstract: An example luminaire-based positioning system calculates a respective distance between an uncommissioned luminaire to each of neighboring commissioned luminaires based on a respective received signal strength indicator (RSSI) measurement. Based on the calculated respective distance to each of the neighboring commissioned luminaires and a set of commissioned location coordinates of each of the neighboring commissioned luminaires, luminaire-based positioning system estimates a set of uncommissioned location coordinates of the uncommissioned luminaire. The luminaire-based positioning system determines a best fit assignment of the set of uncommissioned location coordinates of uncommissioned luminaires in an uncommissioned luminaire list to the set of commissioned location coordinates of non-operational commissioned luminaires in a non-operational luminaire list. The luminaire-based positioning system adjusts a luminaire node map for each of the non-operational commissioned luminaires based on the determined best fit assignment.

Abstract: A system includes a plurality of lighting devices connected in a network to communicate in a service area, and a smart tag configured to communicate with one or more of the lighting devices. Each respective lighting device is configured to transmit a radio frequency signal including a device identifier of the respective lighting device. In response to expiration of a time period or an occurrence of an event, the smart tag is configured to transition from a low power consumption sleep mode to an awake mode. During the awake mode, the smart tag is configured to provide information that enables a processor or other computing device to determine a position of the smart tag or any asset associated with the smart tag in the service area. Upon transmission of the information, the smart tag is transitioned from the awake mode back to the low power consumption sleep mode.

Abstract: Devices in a wireless network, such as wirelessly networked lighting devices, utilize two different types of radios, e.g. implementing two or more protocols such as Bluetooth and WiFi. Such radios operate in overlapping frequency bands of the RF spectrum. Time Division Multiplexing (TDM) of the two types of radio operations mitigates interference between the protocols competing in the spectrum overlap. In the examples with lighting devices, a driver of the light source provides a data bus that may be used as an auxiliary communications channel to implement TDM access by the radios to the overlapping frequency bands.

Abstract: The disclosure provides an example of a system and a method for command execution synchronization in a nodal network. In one example, the method includes starting at a first time, propagating a message including an instruction and timestamp, in a nodal network including a plurality of wireless communication nodes (nodes). The timestamp identifies a second time later than the first time by an amount of time equal to or greater than a period of delay expected for propagation of the message through the nodal network to all of the nodes. The method also includes running a software (soft) clock in each of the nodes, the soft clocks being synchronized to within a timing error tolerance value of the soft clocks in other of the nodes and executing, by each respective one of the nodes, the instruction when the soft clock of the respective nodes reaches the second time identified by the timestamp.

Abstract: A tag is configured to provide information that enables a processor or other computing device to locate the tag and any asset associated with the tag in an area. The tag incorporates a motion sensor responsive to movements of the tag above a predetermined rate and a predetermined magnitude. In response to the movements above the predetermined rate and magnitude, the motion sensor generates a voltage exceeding a predetermined threshold. An energy-saving process exploits the tag's microcontroller's transitions between a “sleep” state and an “awake” state. While asleep, the microcontroller maintains a clock and data in memory, and monitors an input from the motion sensor. In response to voltages at the input over the predetermine threshold, the microcontroller receives signals from one or more nearby beacon nodes in a network operating in the area, process the signals and transmit information based on the processed signals, for a position determination.
