摘要： A motion capture system includes a wearable device (e.g. a glove) suitable for being worn by a user and including one or more markers having respective colors. A video camera acquires a sequence of color frames of the user moving while wearing the glove, while a range camera acquires corresponding depth frames of the same scene. A processing unit processes both color frames and depth frames for reconstructing the 3D positions of the markers. In particular, the depth information provided by the depth frames are used for isolating a validity area within the color frames, and the markers are searched based on their colors, exclusively within the validity area of the color frames. The movements of the user are then captured as a sequence of positions of the markers. Combined use of color information and depth information provide a very reliable and accurate motion capture.

摘要： A method for enabling a round-trip packet loss measurement between two nodes of a packet-switched communication network exchanging packets comprising a packet loss field settable to an idle value or one or more measurement values. The first node transmits to the second node first packets having the packet loss field set to a measurement value. Upon reception of each first packet, the second node transmits back to the first node a respective second packet having the packet loss field set to a measurement value. Upon reception of each second packet, the first node transmits back to the second node a respective third packet having the packet loss field set to a measurement value. A measurement point placed between the two nodes may count the number of first packets and the number of third packets and use them to provide a round-trip packet loss measurement.

摘要： A tracking system for tracking the movement of a moving entity is provided. The tracking system comprises a tracking device configured to move together with the moving entity and provide data associated with the movement of the moving entity, and a detection module configured to, on the basis of the data associated with the movement of the moving entity, perform a detection process to detect an anomaly in the data, the detection process comprising a machine learning algorithm. The tracking system is further configured to, in case the anomaly is detected, issue an alert message to be processed at a control station.

摘要： A method and system for statistically tracking the dynamics of a population over an area comprising entry points and exit points such that each population member entering through one entry point either exits through one exit point or stations within the area. At each entry point, an entry counter counts the number of entering members and, at each exit point, an exit counter counts the number of exiting members. Based on the counter values, the dynamics of the population are statistically tracked in terms of evolution in time of the number of members stationing in the area. The number of stationing members is retroactively adjusted when during an observation period it is determined that the number of exiting members is higher than the number of entering members, plus the number of members which were stationing within the area at the beginning of the observation period.

摘要： It is disclosed a method for transmitting a bidirectional packet flow between two nodes of a packet-switched communication network. Each node applies a respective marking value to the packets to be transmitted to the other node. Each node switches the respective marking value applicable to the packets to be transmitted to the other node upon detection that the marking value applied to the packets which are being received from the other node has been switched. Before switching its respective marking value applicable to the packets to be transmitted to the other node, one of the nodes waits a wait time TW. A measurement point placed between the two nodes may provide RTT measurements based on the detection times of the switching of the applicable marking value in the transmitted packets. However, the measurement point may provide correct RTT measurements only if it knows the value of the wait time TW.

摘要： A communication system includes a communication network and a communication system node. The communication system node communicates with the communication network via a first communication link, and establishes a second communication link with at least one user equipment to allow the user equipment to connect to the communication network. The second communication link is an unmanaged communication link. A backhauling provider module associated with the communication network dynamically allocates backhauling resources to the first communication link for data transmission between the node and the communication network based on the user equipment's parameters.

摘要： A method for estimating an occupancy level of a geographic area includes transmitting first signals to and receiving second signals from bodies within the geographic area by backscattering of the first signals. The bodies include first bodies permanently within the geographic area and second bodies temporarily within the geographic area. According to the first and second signals, a first map of the first bodies within the geographic area is generated. At a specified time period, following a reference time period, transmission of the first signals, reception of the radio signals and generation of the first map is repeated. According to the first and second signals, a second map of the bodies within the geographic area is generated. A number of the second bodies within the geographic area during the specified time period is determined as the occupancy level based on comparing the first map to the second map.
