摘要： A retrofit system for the monitoring of seatbelt status in mass transit vehicles is adapted for retrofitting in different existing vehicles and includes a plurality of non-contact position sensors each associated with the buckle and tongue of a seatbelt, and a seat pan upholstery module with a seat occupancy sensor fixed to its inner side. The sensor of the non-contact position sensors is adapted to be fixed to an external surface of the buckle housing. A monitoring unit is coupled to the non-contact position sensors and occupancy sensors and to a display of seatbelt status comprising an indication that, when each of the seats is occupied, whether the respective seatbelt is in the fastened positioned or a released position.

摘要： A system (100) for monitoring stability of trees (10) in an area includes a server (101), one or more sensor modules (102, 202) being attached to each of the trees (10) in a network of trees, configured for obtaining tilt angle data pertaining to inclination of at least a portion of the tree (10), and relaying the tilt angle data to the server (101), a weather observing device (103, 203) connected to the server (101), for obtaining localized environmental variables representing a local weather condition in the area, and a monitoring platform (20) connected with the server (101), configured for storing and processing the data. The system is configured for monitoring, based on the data and the environmental variables, the tilt angle data of each of the trees (10), and identifying one or more abnormalities of one or more of the trees (10), and indicating through the monitoring platform (20) the one or more abnormalities.

摘要： A detection system (100) and a method for identifying structural change (300) with a substrate (200) includes a sensor (101) configured to resonate at variable frequencies, the resonant frequency of the sensor changing in response to structural change in the substrate, a detector (102) located in proximity to the sensor for detecting the resonant frequency of the sensor, and a receiving device (103) in communication with the detector for receiving information output by the detector, an analyzing device (108) in communication with the receiving device for and interpreting information output by the receiving device. The sensor includes an engagement surface for engaging the substrate. The detector is located on the sensor and away from the engagement surface in such a way that the sensor and the detector are arranged to form a laminated structure.
