  • Patent number: 11401049
    Abstract: Proposed are a system and method for checking out a passenger hand-luggage in an airport. The system for checking out a passenger hand-luggage in an airport includes: a platform configured to load a passenger hand-luggage thereon; a weight measurer configured to measure a weight of the passenger hand-luggage loaded onto the platform; a size measurer configured to measure a size of the passenger hand-luggage loaded onto the platform; an allowance-information provider configured to provide allowance information based on the loaded passenger hand-luggage; and a regulation-based determiner configured to compare the weight and size of the passenger hand-luggage measured by the weight measurer and the size measurer with an allowance allowed for the loaded passenger hand-luggage, and provide check-out information about whether the passenger hand-luggage loaded onto the platform is within the allowance.
    Type: Grant

  • Patent number: 7116648
    Abstract: Asynchronous mobile communication system, and method for implementing a system information broadcasting function in an asynchronous mobile communication system. Upon reception of a system information renewal message from a radio network controller, a base station stores RSIMs generated by all information block segments and scheduling parameters in the message, and then calculates a first transmission time point of each of RSIMs. The base station then forms a queue of the RSIMs according to a queuing algorithm set for the RSIMs. At the end, the base station transmits the RSIM to the air when the transmission time point of a first element of the queue is the same with the current time point at every 20 ms intervals. Therefore, the processing time and the use of memory in the channel card of the base station can be optimized.
