  • Patent number: 11468184
    Abstract: A data protection system includes a data storage apparatus and an information processing apparatus. In the information processing apparatus, a redirection processing apparatus sets a personal storage area corresponding to a user to an accessible state according to a redirection policy. Furthermore, a write control unit controls data writing permission/prohibition for each storage area according to a write management policy. In particular, the write control unit prohibits data writing to a local storage unit except for the storage area to be used to access the personal storage area. With this, the data does not remain in the information processing apparatus, thereby preventing data leakage from the information processing apparatus.

  • Patent number: 10765498
    Abstract: An artificial tooth 30 to be polished is fixed at a tooth neck 32 side and rotated about a tooth axis 33. Abrasives, preferably elastic abrasives formed by kneading abrasive grains into or supporting abrasive grains on an elastic material, are ejected together with a compressed gas at an ejection pressure of from 0.1 MPa to 0.5 MPa onto an occlusal portion 31 side of the artificial tooth 30 while the artificial tooth 30 is being rotated. The abrasives are ejected at an inclination angle ? with respect to the tooth axis 33 of the artificial tooth 30 of from 0° to 90°, and preferably from 15° to 75°. Portions on the occlusal portion 31 and side surfaces 38 of the artificial tooth 30 are thereby polished at the same time by the abrasive sliding over these portions.

  • Publication number: 20190337506
    Abstract: A parking control device includes a controller and a notification unit. The controller executes a parking assistance control for making a vehicle travel from a drop-off position of an occupant of the vehicle to a parking space that is preliminarily determined and making the vehicle be parked in the parking space by automated driving. The controller ceases the parking assistance control in a case where an obstacle is present on a traveling route of the vehicle including the parking space. The notification unit provides a notification that the parking assistance control is stopped. The notification unit transmits information indicating that the parking assistance control is ceased to a device having identification information preliminarily associated with identification information of the vehicle.

  • Patent number: 10325162
    Abstract: There is provided a detection device that includes: a position estimator that estimates a candidate position of a crosswalk in a movement direction of a vehicle and estimates a length of the crosswalk and an intersecting angle between the crosswalk and a roadway using the candidate position; a corrector that corrects the numbers of periods and widths of two basis functions based on the estimated length of the crosswalk and the estimated intersecting angle, the two basis functions corresponding to intervals of white lines of the crosswalk and are orthogonal to each other; and a crosswalk detector that detects whether or not the crosswalk is present using both image data which include the candidate position and the two corrected basis functions.

  • Patent number: 9748909
    Abstract: A gain control circuit includes: a gain switching controller that changes the gains of a fundamental frequency amplifier and an N-multiplied frequency amplifier; and a detection voltage comparator that determines whether the operating state of an N-multiplier is a saturated operation or a linear operation. The detection voltage comparator determines the operating state of the N-multiplier by comparing an amount of change in a detection signal (first detection signal) representing a fundamental frequency signal with respect to an amount of change in the gain of the fundamental frequency amplifier with an amount of change in a detection signal (second detection signal) representing a high-frequency signal with respect to the amount of change in the gain of the fundamental frequency amplifier. The gain switching controller adjusts the gains of the fundamental frequency amplifier and the N-multiplied frequency amplifier on the basis of the operating state of the N-multiplier.

  • Patent number: 9330712
    Abstract: In a data conversion auxiliary module which is at a higher level than a file system in a disk management hierarchy, data stored in a storage medium, which becomes an object, is successively accessed. Then, a data conversion module captures a sector-unit access request to a device driver from the file system, converts data of a sector which is returned from the device driver, and writes the conversion data in the sector. Thereby, data conversion can be executed on a specific region of the storage medium, which is associated with the data in the storage medium.
