  • Interaction terminal and system for elevator
    Patent number: 12151915
    Abstract: An elevator interactive terminal and an elevator interactive system. The elevator interactive system of the present invention comprises an elevator interactive terminal, configured with a social communication media module, wherein a user is registered as a first registered user in the social communication media module; and a server coupled to a communication bus of an elevator system, configured with the social communication media module and to register an elevator as the second registered user in the social communication media module, wherein, based on the social communication media module, interactive communication is performed between the first registered user on the elevator interactive terminal corresponding to the user and the second registered user on the server corresponding to the elevator.

  • Dynamic economic load dispatch by applying dynamic programming to a genetic algorithm
    Patent number: 7752150
    Abstract: In an embodiment, a system and method provide a constraint on a genetic algorithm, and further provide dynamic programming capability to the genetic algorithm. The system and method then allocate load demand over a finite number of time intervals among a number of power generating units as a function of the constraint on the genetic algorithm and the dynamic programming capability of the genetic algorithm.
