  • Publication number: 20200314925
    Abstract: A network system includes an electric apparatus and a communication terminal. The electric apparatus emits a non-connectable beacon by a first communication scheme compliant to Bluetooth (registered trademark). The communication terminal outputs a notification for connection based on the non-connectable beacon. The electric apparatus emits a connectable beacon by the first communication scheme in a case where the electric apparatus directly accepts an operation of a user. In a case where the communication terminal receives the connectable beacon after the user responds to the notification, the communication terminal and the electric apparatus connect to each other by the first communication scheme.

  • Publication number: 20180215014
    Abstract: An article holding device includes a base portion whose lower surface has a holding portion, flow paths communicated with holes in the holding portion, and needles provided on the base portion in a posture inclined with respect to the holding portion. The holding portion sucks and holds a sheet-like article using a negative pressure generated, by supplying a fluid to the flow paths and ejecting the fluid from the holes, between the holding portion and the article on the holding portion. When the article is easily allows air to pass through, the needles is moved to a protruding position in which the needles protrude downward from the holding portion, and the holding portion holds the article by piercing the article using the protruded needles.

  • Patent number: 8487232
    Abstract: A solid state image sensor and an image sensing apparatus incorporated with the solid state image sensor include: pixel arrays each provided with pixels, and an accumulating section e.g. a capacitor CX which sums up and accumulates signal charges obtained by exposure of an object with respect to a corresponding color at different timings when the signal charges are obtained by the pixels of each of the pixel arrays. A reset noise of a converting floating diffusion is outputted after the converting floating diffusion is reset. Thereafter, a summation of the reset noise, and the signal charges accumulated in the accumulating section is outputted.

  • Patent number: 8330843
    Abstract: In a solid-state image sensing device, a method for driving the solid-state image sensing device, and an image sensing system incorporated with the solid-state image sensing device of the invention, pixel signals having two or more different photoelectric conversion characteristics to be outputted from a pixel section are amplified by using an analog gain with respect to each of the photoelectric conversion characteristics for outputting the amplified pixel signals. This enables to reproduce an image having a wide dynamic range while suppressing lowering of the frame rate.

  • Patent number: 8325383
    Abstract: A period when a relative movement between a document, and each of the pixel rows by a certain distance in the vertical direction is made is defined as a frame period, and the frame period is divided into a given number (i) of H periods. A certain H period is allocated as a readout period of each of the pixel rows so that each of the pixel rows reads an identical line of a document, depending on a vertical resolution set by a resolution setter.
