An electronic device able to communicate using both a long-range and a short-range wireless communication technology. A transceiver of the electronic device switches its operation mode based on a power saving mode of the long-range wireless communication technology. In particular, the electronic device switches between a short-range mode and a long-range mode based on the power saving mode of the long-range communication technology.

Dual-mode electronic device

A system and corresponding method is disclosed for monitoring and conducting large-scale performance verification of a city's lighting infrastructure. In particular, the current invention combines measurements of lighting performance measurements along city roadways with regulatory requirements for the roadways. In various embodiments, the current invention then presents a three-dimensional visualization of the adequacy of existing roadway lighting with respect to these regulatory requirements.

Street lighting compliance display and control

A system and method for determining a number of occupants at a location using multiple modalities. The method includes gathering a first data set with a motion sensor of the lighting system. A second data set is gathered with a transceiver of an RF subsystem. First and second estimates are calculated from the second data set using first and second algorithms. The first estimate and the second estimate are fused to create a fused occupant estimate. The first algorithm, the second algorithm, or both the first algorithm and the second algorithm are trained by inputting the second occupant estimate and/or the second set of data to recalibrate parameters of the first algorithm and/or inputting the first occupant estimate and/or the first set of data to recalibrate parameters during training of the second algorithm. A building control system can operated in response to the fused occupant estimate.

Systems and methods using multiple modalities for occupancy sensing

A method () for analyzing output of lighting units () in a lighting system () includes the steps of: (i) simulating (), based on data from a photometric database (), the output of a lighting unit; (ii) receiving and storing (), from a database () of historical information, historical observed data about the output of the lighting unit; (iii) receiving () observed data () about the output of the lighting unit; (iv) generating () a model of the lighting system based at least in part on the simulated output of the lighting unit and the historical observed data about the output of the lighting unit, wherein the model comprises localization information for the lighting unit; and (v) comparing () the received observed data about the output of the lighting unit to the generated model, wherein a fault is detected if the observed data varies from the generated model by a predetermined amount.

Method and system for asset localization, performance assessment, and fault detection

A system and corresponding method is disclosed for monitoring and conducting large-scale performance verification of a city's lighting infrastructure.

Methods for street lighting visualization and computation in 3D interactive platform

A device, system, and method determines occupancy for automated lighting operations. The system includes an occupancy sensor generating a first measurement of an occupancy within a location that illuminated by lights in a lighting system. The system includes a photosensor generating a second measurement of an illumination level within the location, the illumination level indicative of the occupancy within the location. The system includes a control device determining an occupancy state in the location based on the first measurement and determining a result of validating the determined occupancy state based on the second measurement. An agreement between the first and second measurements validating the determined occupancy state while a discrepancy invalidating the determined occupancy state. The control device generates a signal based on the result which is received by a manual on-auto off device to perform a corresponding operation on the lighting system.
