  • Publication number: 20190277958
    Abstract: Disclosed herein is a sensor processing system including an acquisition unit, a time series analysis unit, and a decision unit. The acquisition unit acquires measurement data from a measuring unit. The measuring unit measures a physical quantity, of which a value varies depending on whether a human is present in, or absent from, an object space. The time series analysis unit obtains an analysis model for a time series analysis in which the measurement data acquired at a predetermined timing is represented by multiple items, acquired before the predetermined timing, of the measurement data. The decision unit decides, depending on a decision condition including a condition concerning a coefficient of the analysis model, whether the human is present or absent at the predetermined timing.

  • Patent number: 10409210
    Abstract: An edge emphasis amount determining unit performs a spatial filter process and thereby determines an edge emphasis amount corresponding to edge effect. A first toner counter (a) counts a toner consumption amount including the edge emphasis amount for a non-block-edge pixel in a block as a unit of image processing, and (b) counts a toner consumption amount not including the edge emphasis amount for a block edge pixel in the block. A second toner counter counts a toner consumption amount not including the edge emphasis amount for the non-block-edge pixel and the block edge pixel. A toner consumption amount calculating unit calculates a toner consumption amount of the block on the basis of a difference between a toner counting value of the first toner counter and a toner counting value of the second toner counter.

  • Patent number: 10391578
    Abstract: There is provided an arc welding control method. As to a feeding rate of a welding wire, a forward feeding period and a reverse feeding period are alternated cyclically to generate short-circuiting periods and arc periods. When a constriction of a droplet formed at the welding wire is detected during the short-circuiting period, a welding current is reduced to shift to the arc period. Sensitivity of the detection of constriction is changed according to a waveform parameter of the feeding rate.

  • Patent number: 10379478
    Abstract: A base toner amount is determined without taking edge effect into account. The base toner amount corresponds to a pixel value of image data for which gradation correction has not been performed. For the base toner amount, a first spatial filter process is performed corresponding to a laser profile of the exposure device. A second spatial filter process is performed for the base toner amount before or after the first spatial filter process and thereby an edge emphasis amount is determined corresponding to the edge effect. A toner counter counts as a toner consumption amount a sum of the base toner amount after the first spatial filter process and the edge emphasis amount. Further, a gain control unit multiplies the edge emphasis amount by a coefficient corresponding to the base toner amount after the first spatial filter process and thereby controls a gain of the edge emphasis amount.

    Abstract: An inkjet recording apparatus includes a piezoelectric element, an extraction processing portion, and a drive control portion. The piezoelectric element is provided in correspondence with a nozzle, and upon input of a first drive signal, causes ink to be ejected from the nozzle. The extraction processing portion, when a print process is executed, extracts a non-ejection period during which a non-ejection state continues for more than a reference time period, from an execution period of the print process based on a plurality of pieces of image data printed in the print process, wherein ink is not ejected from the nozzle in the non-ejection state. The drive control portion inputs a second drive signal for causing the piezoelectric element to stir the ink in the nozzle, to the piezoelectric element during a partial period of the non-ejection period extracted by the extraction processing portion.
