    Abstract: A network control method for handover in a mobile time-sensitive network (TSN) communication system is provided. The network control method includes: communicating of a user terminal within a wireless communication range of a first AP with an end system through the first AP; determining whether to handover to a second AP by determining communication strength between the user terminal and the first AP; requesting handover to a controller when the handover to the second AP is determined; reconfiguring a TSN communication operation after the handover, determining handover timing, and generating a handover command by a controller; transmitting the handover command to the first AP, the user terminal, and the second AP; and applying the reconfigured TSN communication operation to the second AP and the user terminal at the handover timing.

    IPC: G06F3/01

    Abstract: A haptic interaction device include: a setting unit configured such that, when a desired stiffness related to a penetration depth of a haptic interaction point in a virtual environment and a feedback force corresponding to the penetration depth is designated, the setting unit sets a feedback force that is to occur when the haptic interaction point penetrates the virtual environment; a checkup unit checking, when a cycle is ended, the stiffness at the cycle during which the haptic interaction point penetrates the virtual environment along a pressing path and moves along a releasing path in the opposite direction to the direction of penetration according to the feedback force that has been set; and a determination unit determining a feedforward force offset value related to a feedback force at the next cycle adjacent to the cycle based on a result of comparing the checked stiffness and the desired stiffness.

    Abstract: Provided is an impact type vibration actuator including a permanent magnet having a stopper insertion portion; a linear guide surrounding the permanent magnet; a stopper protruding into the linear guide and inserted into the stopper insertion portion; and coils provided on at least one end of the permanent magnet to provide alternately attraction and repulsion to the permanent magnet.According to the present invention, since a permanent magnet is not connected to the vibration mass, it is possible to adjust the vibration frequency in a very wide range by adjusting the frequency of the power source applied to the coil, and to adjust vibration intensity by appropriately selecting current intensity, a stopper interval, an elastic means, and the like. In addition, through this, it is possible to provide much more various haptic feedbacks than the prior art.
