  • Localization method and system thereof
    Patent number: 8164522
    Abstract: A positioning method for a sensor node is provided, and the method includes steps of: providing a first antenna having a first omnidirectional radiation pattern on a first plane; rotating the first antenna about an axis substantially parallel to the first plane; transmitting a wireless signal while the first antenna rotates about the axis for every a predetermined central angle; receiving the wireless signal at the sensor node; obtaining Received Signal Strength Indications (RSSIs) of the respective wireless signals; and determining a location of the sensor node according to the RSSIs.
    Type: Grant

  • METHOD FOR RECOGNIZING THE POSITION OF A GAMING DEVICE
    Publication number: 20090170601
    Abstract: A method for recognizing the position of a wireless controller is applied to an interactive gaming device including a wireless controller, a main apparatus and a host. The main apparatus includes a first ultrasonic receiving module, a second ultrasonic receiving module and a third ultrasonic module which are arranged as a triangle shape. The wireless controller includes an ultrasonic transmitting module for sending an ultrasonic wave which is received by the ultrasonic receiving modules in order to obtain three ultrasonic wave transmission times. The main apparatus sends the ultrasonic wave transmission times to the host. The host calculates the ultrasonic wave transmission times and therefore recognizes the position of the wireless controller. When the wireless controller is moved, the host obtains plurality of coordinate values indicating the motion track of the wireless controller. The motion track of the wireless controller is shown in a display by monitoring the coordinate values.
