Abstract: Described herein is method for setting up a network of luminaires and their subsequent operation. A plurality of luminaires are located on a street (24, 29), and each luminaire comprises a control module (23, 28). The method for setting up the network comprises, for each control module, scanning the environment and providing environmental information to a central server, which, allocates the control modules and their associated luminaires into groups (A, B). A group controller (23?, 28?, 31, 32) is allocated for each group which has long-distance communication with the server and short-distance communication with control modules within its group. Each group controller and control modules within the group form a network which can operate autonomously or under the control of the server. Some of the control modules may include sensors (S1, S2) which provide signals indicative of changes in the environment allowing the network to adapt its operation in accordance with those changes.

Abstract: Apparatuses and Methods for sorting a data set. A data storage is divided into a plurality of buckets that is each associated with a respective key value. A plurality of stripes is identified in each bucket. A plurality of data stripe sets is defined that has one stripe within each respective bucket. A first and a second in-place partial bucket radix sort are performed on data items contained within the first and second data stripe sets, respectively, using an initial radix. Incorrectly sorted data items in the first bucket are grouped by a first processor and incorrectly sorted data items in the second bucket are grouped by a second processor into a respective incorrect data item group within each bucket. A radix sort is then performed using the initial radix on the items within the respective incorrect data item group. A first level sorted output is produced.

Abstract: A control method for a luminaire with a daylight sensor, comprising: obtaining a first value (?) representative for the angle of the sun with respect to the horizon; if the obtained first value is within a first predetermined range corresponding with a dusk or dawn range, performing the following steps: obtaining a second value (Ev) representative for a light level using the daylight sensor of the luminaire; and controlling the switching on or off of the luminaire when the obtained second value (Ev) fulfils a first predetermined criterion; registering over time, for at least one determined obtained second value, at least one corresponding obtained first value (?); and/or, for at least one determined first value, at least one corresponding obtained second value (Ev); adjusting the first predetermined criterion based on the registrations over time.

Abstract: Method for updating a bootloader of a controller of a light, comprising at least one processor, at least one bootloader storage area, at least one application storage area, and a file storage area, a first, bootloader file stored in a first bootloader storage area, said method comprising: transfer-ring to the controller a bootloader updating programme packet provided outside of the controller and which comprises or can generate a bootloader updating file which comprises either a complete up-to-date second bootloader file or programme parts supplementing the first bootloader file to form an up-to-date second bootloader file, storing the bootloader updating file in the file storage area of the controller, and, in the case of a sufficient minimum voltage being available to the controller, writing the first bootloader storage area with the bootloader updating file from the file storage area.

Abstract: Described herein is method for the operation and the expansion of a network of lights, each light in the network including a control module which is assigned to a group, each control module being in communication with a group controller as well as control modules in the same group. The network can be expanded by installing new lights with their associated control modules (19), and each new control module scans its environment and transmits environmental information to a central server (20) where the environmental information is analysed and the new control modules are allocated into groups (21). After allocation to a group in which control modules may be moved from one group to another or a new group is formed, the new control modules are available for normal operation. This process is repeated for each new light and associated control module.

Abstract: A first quicksort is performed in parallel across pairs of partitions of a dataset assigned to respective ones of available processors, including swapping elements of a first partition of a given one of the pairs that are larger than a pivot with elements of a second partition of the given pair that are smaller than the pivot. A second quicksort is performed in parallel across those partitions having elements left unsorted by the first quicksort, and first misplaced elements from a first side of the dataset corresponding to the first partition are swapped with second misplaced elements from a second side of the dataset corresponding to the second partition to produce a first dataset having elements equal to or lower than the pivot and a second dataset having elements equal to or higher than the pivot.
