    Abstract: A distance measurement system includes a distance measurement device and an external processing device. Here, the distance measurement device receives reflected light from a subject for a plurality of exposure periods in a frame in which irradiation light is emitted, switches a plurality of distance calculation expressions according to an amount of charge measured for each exposure period, and calculates a measured distance to the subject from the amount of charge measured for each exposure period. The external processing device acquires the measured distance from the distance measurement device and performs data processing. Then, the external processing device predicts a measured distance including a distance error caused by an influence of multipath. The external processing device generates a correction expression for correcting the measured distance. The external processing device corrects the measured distance acquired from the distance measurement device using the correction expression.

  • Publication number: 20210270971
    Abstract: At a preparatory step for correction, in a state that a reflective tape made with a retroreflective material is pasted in advance onto a floor surface of a measurement space in a direction away from the distance-measuring device, a distance La to an inside area of the reflective tape, and a distance Lb to an outside area of the reflective tape adjacent to the inside area are measured by the distance-measuring device, while measurement positions Y are being scanned along the reflective tape. A correction formula for converting the distance Lb to the distance La is created from a relationship between the distance La and the distance Lb obtained at each measurement position Y. At an actual measurement step, a distance (actual measurement value x) to the target object measured by the distance-measuring device is corrected in accordance with the correction formula, and a measurement-distance corrected value y is calculated.

  • Patent number: 8808889
    Abstract: The sealed battery has a battery container (4, 5) and a power generating element sealed inside the battery container. The battery container is provided with a fill opening (12), an annular ridge (16), which extends around the entire circumference of the outer face surrounding the fill opening, and an annular indentation (15) on the inside of the inner wall surface of the annular ridge, and has a sealing cap (8), which fits into the annular indentation and covers the fill opening. The sealing cap is joined by being welded to the inner wall surface of the annular ridge around the entire circumference at the edge thereof. Since heat is not well transferred from the inside to the outside of the outer wall surface of the annular ridge, the effective thermal capacity during welding is mostly determined by the structure of the area inside the outer wall surface of the annular ridge. Consequently, the effective thermal capacity is nearly uniform independent of direction.

  • Patent number: 8207912
    Abstract: Sustain pulses are alternately applied to a pair of display electrodes of discharge cells provided in a plasma display panel (PDP) to generate a sustain discharge to display an image on the PDP. The sustain pulses include two-crests discharge voltage waveforms having a first maximum and second maximum values, in which discharges are generated twice in a half cycle.
