摘要： A method for modifying data from a Real-Time Location System (RTLS) involving: receiving building arrangement information having two locations and one or more identifiable characteristics of the two locations; obtaining identifying information of at least one tag and at least two sensors in the RTLS; generating a mapping of the identifying information with the one or more identifiable characteristics of the two locations; receiving location information of the at least one tag based on the mapping, the location information indicating a presence of the at least one tag in the two locations at separate times; determining that the location information includes at least one gap because the at least one tag cannot proceed directly between the two locations in the building arrangement information; and updating the location information based on an interpolation of the location information to fill in the at least one gap.

摘要： A method and system that enables a computer to determine a cause of occupancy of a predetermined area using real-time location information. The real-time location information is processed to determine occupancy information of each of a plurality of zones of the predetermined area. The (combined) occupancy information is processed using a machine-learning model to predict an occupancy cause of the predetermined zones of the predetermined area.

摘要： An infectious disease transmission tracking system (10) includes a real-time locating system (RTLS) (12) configured to track locations of tags (14, 15) in a monitored area. At least one electronic processor (22) is in operative communication with the RTLS to receive locations of tags in the monitored area. A non-transitory storage medium stores, a map (30) of the monitored area; a nodes database (32) storing information on nodes (18) in which each node is a person, a mobile object, or a map zone and the nodes database stores information on the nodes including at least (i) an identification of each node as a person, a mobile object, or a map zone, (ii) an identification of a tag associated with each node that is identified as a person or a mobile object, (iii) locational information on the map for each node that is identified as a map zone, and (iv) an infection likelihood for each node with respect to a tracked pathogen; and a pathogen database (34) storing infectious transmission information for at least the tracked pathogen including one or more transmission modes for the tracked pathogen and at least one node residency time for the tracked pathogen. The non-transitory storage medium includes instructions readable and executable by the at least one 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 associated with the infected node received from the RTLS wherein an infected node has a non-zero infection likelihood respective to the tracked pathogen which satisfies an infected criterion; computing an infectious zone (36) on the map along the pathway using the infectious transmission information stored in the pathogen database; for each node contacting the infectious zone, adjusting the infection likelihood of the contacting node in the nodes database based on at least the infectious transmission information for the tracked pathogen and designating the contacting node as an infected node if the updated infection likelihood of the contacting node satisfies the infected criterion.

摘要： Some embodiments are directed to location-tracking system (100) comprising a location database (120) configured to receive a plurality of location updates from a plurality of tracking devices (112, 113), the plurality of location updates indicating the location of one or more objects, the location updates being stored encrypted with a cryptographic database encryption-key (130), multiple location-analysis devices execute a multi-party computation protocol on the encrypted location updates using a stored key-share, thus jointly computing a location-analysis result secret-shared among the multiple location analysis devices.
