  • Publication number: 20190331076
    Abstract: A fuel injection valve includes: a coil; a stationary core to generate a magnetic force; a movable structure including a moving core and a valve body and internally having a movable flow passage; and a body that internally accommodates the movable structure and internally has a part of the flow passage. The movable structure includes a throttle portion at which a passage area of the movable flow passage is partially throttled. The flow passage includes a throttle flow passage defined by the throttle portion and a separate flow passage between the movable structure and the body. A passage area of the separate flow passage is smaller than a passage area of the throttle flow passage. A position of the separate flow passage in a direction perpendicular to a moving direction of the movable structure is different from an outermost peripheral position of the moving core.

  • Patent number: 10079087
    Abstract: In the dither current power supply control method, in order to prevent occurrence of a difference between the target average current and the detected average current, which is caused when a medium current (I0) between a dither large current (I2) and a dither small current (I1) and a waveform average (Ia) of the dither current are different from each other depending on a response time difference (a?b) between a rise time (b) and a fall time (a) of the dither current, negative feedback control is carried out by using a command medium current corresponding to the target average current corrected by a correction parameter based on experimentally measured data, thereby suppressing occurrence of a transient fluctuation error by the negative feedback control, so that a highly precise and stable load current is acquired.

  • Publication number: 20170049366
    Abstract: The present invention provides an information processing device that, when the height of a reference plane of a bed is being set on a screen using a setting unit, clearly indicates, on a captured image, a region that is located at the height of the reference plane, based on depth information that is included in the captured image. It thereby becomes possible to readily set the reference plane of the bed, which serves as a reference for behavior of a person being watched over. Thereafter, the information processing device detects the behavior of the person being watched over, by determining whether the positional relationship between the reference plane of the bed and the person being watched over satisfies a predetermined condition.

  • Publication number: 20170014051
    Abstract: The present invention provides an information processing device that sets a range designated within a captured image (3) as a range of a bed reference plane. During this setting, the information processing device evaluates whether the designated range is suitable as the range of the bed reference plane, based on a predetermined evaluation condition, and presents the result of that evaluation to a user. It is thereby possible to easily perform setting relating to a position of the bed that serves as a reference for detecting the behavior of a person being watched over.

  • Publication number: 20160345871
    Abstract: The present invention provides an information processing device that acquires a captured image including depth information that is captured by an image capturing device including a depth sensor, and determines whether a positional relationship between a person being watched over and a region of a bed satisfies a predetermined condition, based on the depth for each pixel. In the case where a state in which the depth for each pixel within the captured image cannot be acquired by the depth sensor continues for a given period of time or longer, the information processing device notifies that there is a possibility that watching over of the person being watched over is not being performed normally.
