  • Publication number: 20120035802
    Abstract: A learning diagnostic system for a working machine is capable of making a fault diagnosis of the working machine universally relative to various types of sensor information, and preventing a failure in the working machine by enabling a fault diagnosis even in a transient operating state that represents a transitional state between operating states. A state learning device 201 sorts inputted sensor data 101a into one under a steady operating state and one under a transient operating state, and generates, through learning, steady state data 102a and intermediate state data 103a, each including a permissible error. A state diagnostic device 202 uses the steady state data 102a to determine whether an operating state of the working machine related to the inputted sensor data is the steady operating state or the transient operating state, and make a fault determination in the steady operating state.

  • Patent number: 8054045
    Abstract: In a status detector for a power supply, a power supply, and an initial characteristic extracting device for use with the power supply, a measuring unit obtains measured values of at least current, voltage and temperature of the electricity accumulating unit. A processing unit executes status detection of the electricity accumulating unit by using the measured values and the characteristic information of the electricity accumulating unit which is stored in a memory unit. A discrepancy detecting unit detects the presence of a discrepancy away from a theoretical value when a result of the status detection is changed over a predetermined threshold or reversed with respect to the measured values. A modifying unit modifies the characteristic information depending on the detected discrepancy.

  • Publication number: 20110046858
    Abstract: In this work vehicle, a control unit controls a shift in a speed gear of a transmission according to the vehicle velocity. The control unit determines whether or not the acceleration rate of the vehicle is equal to or less than a predetermined threshold when the vehicle velocity is within a predetermined first range. The control unit switches a lock-up clutch from a not-connected state to a connected state when the acceleration rate of the vehicle is equal to or less than the predetermined threshold. The control unit maintains the lock-up clutch in a not-connected state when the acceleration rate of the vehicle is greater than the predetermined threshold.

  • Patent number: 7474970
    Abstract: An information processing apparatus is disclosed. The information processing apparatus includes a hard disk drive, an acceleration sensor, a determination section, and a threshold value setup section. The hard disk drive is capable of retracting a head to a data-free landing zone. The acceleration sensor detects acceleration. The determination section obtains high frequency components from acceleration information detected by the acceleration sensor, obtains a vibration level corresponding to the obtained high frequency components, compares the vibration level with a threshold value which has been set up, and determines whether or not there is a necessity to retract the head of the hard disk drive to the data-free landing zone. The threshold value setup section allows a user to change the threshold value and set up the changed threshold value.
