  • Clock drift determination
    Patent number: 11507132
    Abstract: A method for determining a clock drift comprises determining a drift of a clock relative to a reference clock based on two signals from the reference clock and a further signal. The method can be used for time synchronization and is suitable for implementation on resource-constrained devices. An anchor point implementing the method and a real-time locating system comprising such an anchor point are also disclosed.

  • CARRIER UTILIZATION TRACKING
    Publication number: 20220129843
    Abstract: An arrangement for detecting a load carried by a carrier intended to be tracked by a real-time locating system comprises: a tag intended to be arranged on the carrier, the tag being configured to generate a wireless signal allowing determination of a position of the tag; and at least one detector configured to detect the load carried by the carrier and to generate a wireless signal indicative of at least one of whether or not a load is carried by the carrier and an amount of load carried by the carrier. The arrangement allows for accurate carrier utilization tracking in a cost-effective manner. A real-time locating system comprising such an arrangement and a method for detecting a load carried by a carrier are also disclosed.
