  • Publication number: 20240098223
    Abstract: An abnormality behind a shielding object is discovered. There is provided a monitoring system including a video acquirer, a detector, and a notifier. The video acquirer of the monitoring system acquires a video. The detector of the monitoring system detects entering of a target object into a blind spot generated by a shielding object in the video and appearance of the target object from the blind spot. If the target object does not appear from the blind spot even after a first time elapses since entering of the target object into the blind spot, the notifier of the monitoring system makes a notification.

  • Publication number: 20180232139
    Abstract: An apparatus of this invention is directed to an information processing apparatus that discriminates, without adding any hardware component, between a window to be operated and a window not to be operated. The information processing apparatus includes a display unit that displays at least two windows, a determiner that determines a touch for maintaining screen on a display region of the at least two windows, and a controller that maintains, even when an operation for the at least two windows is input, display of a window on which the touch for maintaining screen has been determined, regardless of the operation. The controller executes the input operation for a window on which the touch for maintaining screen has not been determined.

  • Patent number: 7723808
    Abstract: The present invention provides a semiconductor device and a method of manufacturing a semiconductor device in which a driving force can be increased by increasing a strain amount given by a stressed film in a MOS transistor including an elevated region. On a silicon substrate, a device isolation region 102, a gate insulating film 103, a gate electrode 104, an extension 105, and a sidewall insulating film 106 are formed. After that, an elevated region is formed, and a source/drain region 108 and a silicide layer 109 are formed. Subsequently, the sidewall insulating film 106 is etched to provide a gap from the elevated region 107, and a stressed film 110 is buried in the gap.

  • Patent number: 6997034
    Abstract: When a knocking detector mounted on a cylinder block of an engine is inspected, the cylinder block is vibrated by a vibrating unit via a housing connected to the cylinder block, and the performance of the knocking detector is judged based on whether or not a peak value of a voltage variation value serving as a detection value of the knocking detector is below a threshold value which has been set based on a peak value of a test voltage variation value serving as a reference value.

  • Patent number: 6802207
    Abstract: The invention discloses a rotational driving apparatus for cold testing an internal combustion engine to which a ring gear is attached. The rotational driving apparatus has a rotor that is rotatively driven about the rotation axis of the ring gear of an internal combustion engine that is in the testing position. A pivot arm is supported rotatably with respect to the rotor via a link pin. The front end portion of the pivot arm is provided with an engaging portion that can engage the ring gear through shifting to the inward side with respect to the radial direction. The pivot arm also has a portion that extends rearward of the link pin. When the rotor is rotated, this portion extending to the rear generates a torque in the direction in which the engaging portion is shifted so as to engage the ring gear. A link that extends at an angle that is nearly perpendicular to the rotation axis is joined to the rear end of the pivot arm.
