    Abstract: The invention discloses a complex network-based high speed train system safety evaluation method. The method includes steps as follows: (1) constructing a network model of a physical structure of a high speed train system, and constructing a functional attribute degree of a node based on the network model; (2) extracting a functional attribute degree, a failure rate and mean time between failures of a component as an input quantity, conducting an SVM training using LIBSVM software; (3) conducting a weighted kNN-SVM judgment: an unclassifiable sample point is judged so as to obtain a safety level of the high speed train system. For a high speed train system having a complicated physical structure and operation conditions, the method can evaluate the degree of influences on system safety when a state of a component in the system changes. The experimental result shows that the algorithm has high accuracy and good practicality.

  • Patent number: 9032798
    Abstract: Provided are a device (10) and a method for measuring the crispness of a food product. An item to be measured (22) comprising a porous food product is broken apart by causing the blade of a knife (14) to penetrate into the item. A vibration detector (18) attached to the knife (14) detects crack vibrations from cracks that form when the item to be measured (22) is broken apart. In a computer (20), the small crack vibrations of a predetermined vibration power or less that are included in the crack vibrations within an individual cracking duration time are extracted from the detected crack vibrations. Crispness is measured on the basis of the number of extracted small crack vibrations counted (number of cracks).

  • Patent number: 9027382
    Abstract: The present invention provides a case for an impact detector, including: a front case; a weight to move from an initial position when a detection target of the impact detector inclines more than a predetermined angle; a first rear case to be covered by the front case, including a guide member set at a first inclination angle, through which the weight moves; a second rear case to be covered by the front case, including a guide member set at a second inclination angle different from the first inclination angle, through which the weight moves; and a resistance reducer to reduce moving resistance of the weight. In the optimal case for the impact detector, the front case is used in common for the first rear case and the second rear case, the weight can move smoothly in either case, and the impact can be easily detected.

The metal plate (14) is connected to a control board (400) in the case (10), and the voltage of the metal plate (14) is determined. A reference voltage is applied to the metal plate (14), and the case (10) is grounded. When the metal plate (14) is brought into contact with the case (10) or disconnected due to a crash, the voltage of the metal plate (14) is thereby changed, and the control board (400) detects a crash, based on the change in the voltage.

  • Patent number: 8762044
    Abstract: A Guided Soft Target System is disclosed that includes a subject vehicle and a dynamic motion element (DME). The subject vehicle may be accelerated at an arbitrary rate to a speed corresponding to the speed in its own predetermined trajectory. Each of the DME vehicles computes its target speed as a ratio of the subject vehicle's speed at each waypoint location, and modulates its speed control to achieve this target speed. To further compensate for timing differences along the target path, each DME computes its longitudinal error along the path relative to its target position, as dictated by the position of the subject vehicle within its own trajectory, and each DME's target speed is modulated in order to minimize the longitudinal error along the predetermined trajectory.

  • Patent number: 8751143
    Abstract: A cam actuated hydraulic brake system and an in plane tensioner pulley belt drive system may be used on autonomous vehicles, such as dynamic motion elements for the evaluation of various crash avoidance technologies. The brake system utilizes a cam driven by a servo to push the piston push rod of a hydraulic master brake cylinder, thus distributing pressurized brake fluid throughout the brake system. The pulley drive system uses an articulating arm for the driven pulley, and that arm may also have connected to it one or two tension pulleys, each of which is in contact with the belt. Because the drive pulley and the tensioner pulleys pivot about the same pivot axis, the needed belt length remains nearly constant across the entire range of the articulating arm.
