Abstract: A system (10) for optimizing quality control of tracking data includes a real-time locating service (RTLS) (12) configured to perform tracking of persons or items in a building that are tagged with associated infrared (IR) or radio frequency (RF) tags (14) to generate candidate traces (40). At least one electronic processor (20) is programmed to: score the candidate traces including, for each candidate trace being scored, determine whether one or more location reports is missing from the candidate trace; and reduce the fitness score of the candidate trace based on a number of missing reports; detect deviations between the candidate traces and the intended workflow; and store the deviations in a database (23, 26).

Abstract: A system (10) includes a real-time locating system (RTLS) (12) configured to track locations of tags (14, 15) in a monitored area. A non-transitory storage medium stores, a map (30) of the monitored area; a nodes database (32) storing information on nodes (18); and a pathogen database (34) storing infectious transmission information. The non-transitory storage medium includes instructions readable and executable by an electronic processor to perform an infectious disease transmission tracking method (100) including: computing a pathway (35) on the map of at least one infected node using locations of the tag wherein an infected node has a non-zero infection likelihood; computing an infectious zone (36) on the map along the pathway; for each node contacting the infectious zone, adjusting the infection likelihood of the contacting node and designating the contacting node as an infected node if the updated infection likelihood of the contacting node satisfies an infected criterion.

Abstract: Disclosed is a system, a kit, a use and an in vitro method for assessing whether a human patient suffering from periodontitis has mild periodontitis or advanced periodontitis. The system and method are based on the insight to apply a clustering technique to a reference set of patient data, and then further discriminating the sets of bio markers to be applied. The clusters are determined on the basis of the biomarkers Hepatocyte Growth Factor (HGF), Matrix metalloproteinase 8 (MMP8), and Matrix metalloproteinase 9 (MMP9). The actual classification of the patient is done on the basis of the measurement of the concentrations of either of two sets of biomarkers. For one cluster these are Interleukin-1? (IL1?), Interleukin-6 (IL6), and Collagen Telopeptide. For the other cluster, these are HGF and metallopeptidase inhibitor 1 (TIMP1).

Abstract: Disclosed is a system for analysis of microscopic image data acquired from biological cells. The system includes a data processing system which is configured to read the image data and determine a plurality of vertices, wherein each of the vertices represents a location of an entity of interest within a region of interest of the image data. The data processing system generates a plurality of graphs, wherein for each of the graphs, the generation of the respective graph includes generating a plurality of edges, wherein each of the edges has two of the plurality of vertices associated therewith. For each of the graphs one or more vertex sets are identified, each of which consisting of one or more of the plurality of vertices. The data processing system further determines, for each of the graphs, a number of the identified vertex sets.

Abstract: Disclosed is an in vitro method for assessing whether a human patient suffering from periodontitis has mild periodontitis or advanced periodontitis. The method is based on the insight to determine a selection of three biomarker proteins. Accordingly, in a sample of saliva a patient suffering from periodontitis, the concentrations are measured of the proteins Interleukin-1? (IL-1?), Matrix metalloproteinase-9 (MMP-9) and at least one of the proteins: Interleukin-6 (IL-6), and Matrix metalloproteinase-3 (MMP-3). Based on the concentrations as measured, a value is determined reflecting the joint concentrations for said proteins. This value is compared with a threshold value reflecting in the same manner the joint concentrations associated with advanced periodontitis. The comparison allows assessing whether the testing value is indicative of the presence of advanced periodontitis or of mild periodontitis in said patient.

Abstract: An insect control system has a light source arrangement (10) comprising one or more light sources with tunable spectrum, polarization, intensity and or flickering pattern. The system enables a particular type of insect to be attracted or repelled in a particular time period.

Abstract: The disclosure describes is a channel switching strategy and corresponding protocol for a mesh network which comprises a segment controller (SC) and a large number of outdoor luminaire controllers (OLCs) or other network nodes. A channel switching process is initiated and managed by the SC which transmits a channel switching command to all nodes in the system. Following the actual channel switch, the SC delegate's responsibility to request an orphan node to switch to the new channel to a selected delegate node which is a neighbor node of the orphan node. The selection of the delegate node may be based on a prioritization. When an OLC does not receive any messages for a specified, prolonged period of time, it may scan available frequency bands to find the (new) channel in which the networked system operates at that time.

Abstract: The invention relates to a channel switching strategy and corresponding protocol for a mesh network which comprises a segment controller, SC, (10) and a large number of outdoor luminaire controllers, OLCs, (20) or other network nodes. A channel switching process is initiated and managed by the SC (10) which transmits a channel switching command to all nodes in the system. Following the actual channel switch, the SC (10) delegates the responsibility to request an orphan node (24) to switch to the new channel to a selected delegate node (22) which may be a neighbor node of the orphan node (24). The selection of the delegate node (22) may be based on a previous link quality or geographical closeness. When an OLC does not receive any response messages for a specified, prolonged period of time, it may scan available frequency bands to find the (new) channel in which the networked system operates at that time.
