  • Patent number: 11262198
    Abstract: Pressure assisted positioning method and device thereof are disclosed in the present invention. The pressure assisted positioning device is exerted for positioning a target under the circumstance of altitude change since the target enters a specific region. The pressure assisted positioning method includes the following steps. First, confirming the entrance of the specific region of the target and detecting a plurality of pressure data. Then, calculating a pressure variation between the two selected pressure data. At last, comparing the pressure variation to a threshold. An altitude change within the specific region is confirmed as the pressure variation is greater than the threshold. On the other hand, as the pressure variation is greater than the threshold, it refers to no altitude change within the specific region.

  • Publication number: 20180159576
    Abstract: A communication device and a control method thereof are applied to a movable apparatus. The communication device includes a number of directional signal transceivers and a processor wherein aiming directions of the directional signal transceivers are different from on another. The processor is electrically connected to the directional signal transceivers, and configured to determine whether an intermediate communication device exists according to a wireless signal received by a part of the directional signal transceivers. When the intermediate communication device exists, the processor selects one of the directional signal transceivers for transmitting the apparatus information of the movable apparatus according to a position of the intermediate communication device.

  • Patent number: 9420412
    Abstract: A vehicle position calibration method and apparatus thereof are disclosed. The vehicle position calibration method is applicable to a vehicle having a mobile calibration positioning device and at least a vehicle having a positioning device to be calibrated. The method starts with the mobile calibration positioning device transmitting a message of positioning precision level to the positioning device to be calibrated. Then, the positioning device to be calibrated sends a calibration request to the mobile calibration positioning device according to the message of positioning precision level; then the mobile calibration positioning device detects a relative position between the mobile calibration positioning device and the positioning device to be calibrated according to the calibration request.

  • Patent number: 8933792
    Abstract: A moving carrier signal transmission method and a signal transmission device using the same are provided. A main moving carrier acquires an identification code of an ambient moving carrier. The main moving carrier adds an identification code of the main moving carrier and the identification code of the ambient moving carrier in a data request and then sends out the data request to the ambient moving carrier according to the identification code of the ambient moving carrier. When the ambient moving carrier obtains the data request, the ambient moving carrier adds the identification code of the main moving carrier in a moving carrier list and transmits the moving carrier list to the main moving carrier.

  • Patent number: 8896432
    Abstract: A cooperative event data record system includes an in-car system working cooperatively with a communication system. The in-car system has a communication module, a cooperative event record processing unit and an impact determination module. The cooperative event record processing unit connects to the communication module, the impact determination module and an event data record unit. The impact determination module transmits a signal to the cooperative event record processing unit. The communication module transmits a request from the cooperative event record processing unit to a communication module element of the communication system, and receives a response from the communication module element. According to the response, the cooperative event record processing unit stores at least a video data to the event data record unit, or retrieves video data from the event data record unit.
