  • Pseudo rock and analysis system using the same
    Patent number: 8991260
    Abstract: A pseudo rock includes a housing, a strain sensor, a three-axis acceleration sensor, a vibration generator and a controller. The housing has an average shape and size of rocks. The strain sensor detects a stress acting in positive and negative directions of each axis with respect to three-dimensional coordinates using the center of the housing as the origin. The three-axis acceleration sensor detects acceleration acting in each axis of the three-dimensional coordinates. The vibration generator produces vibration in a specific direction with respect to the three-dimensional coordinates. The controller converts respective detected values of the strain sensor and the three-axis acceleration sensor into vibration pulses of specific patterns and outputting the vibration pulses to the vibration generator.
