  • Patent number: 9460429
    Abstract: An automatic toll collection system includes a mobile app that receives a plurality of toll gantry information from a database, reads GPS location data received from the mobile device hosting the app, and creates a plurality of trip segments using the GPS location data and time stamp. The system then determines whether the mobile device is travelling on a road where toll ought to be collected by comparing the trip segments with the toll gantry information. If the vehicle is passing through a gantry or toll road, the system will then calculate toll charges based on the trip segments and gantry information, generate a toll charge transaction, and notify the mobile user of the toll charge.

  • Publication number: 20150335385
    Abstract: An active tracking system includes an imager configured to image the temperature of a biological tissue and a heating laser configured to heat regions of the biological tissue. The imager locates high-temperature regions of the biological tissue and the heating laser is controlled to point toward target regions of the biological tissue based on the located high-temperature regions. The active tracking system can be used to control a heating laser to continuously heat a target region of a biological tissue even when the target region moves relative to the heating laser. The active tracking system could allow one or more target regions of a biological tissue to be ‘tagged’ with heat by the heating laser and to be tracked even when the one or more target regions move relative to the heating laser. Devices and methods for operating such active tracking systems are also provided.
