  • Publication number: 20240016448
    Abstract: Measurement control part measures contact pressures and a contact speed of a hand of a contacting person. The contact pressures change over time at respective positions, as measured values respectively based on two sensors when the hand of the contacting person touches sequentially to the two sensors being capable of detecting contact pressure. A determination control part compares measured values with reference ranges respectively, the reference range being a predetermined for a contacted person feeling comfortable when touched by the contacting person, and determines whether or not the measured value is within the reference range for each of measured values. An evaluation control part evaluates that the touching of the contacting person is a comfortable touching when all the measured values are within corresponding reference ranges respectively, and evaluates that the touching of the contacting person is an uncomfortable touching when one measured value is outside the corresponding reference range.

  • Patent number: 10888252
    Abstract: A scapulae position measurement device and method includes a main body extending in the vertical direction, configured to be positioned to run along the spinal column, having a vertical scale, and a moveable arm, extending in a horizontal direction on the right or left side of the main body, having a horizontal scale. The scapulae position measurement device is capable of measuring position changes of the horizontal direction (X axis) and vertical direction (Y axis) of the scapulae, and capable of displaying the tension/relax state of the surrounding muscles of the scapulae with an objective numerical value.

  • Patent number: 10723180
    Abstract: In a tire, in a cross-section of a core of a bead taken at a plane perpendicular to the circumferential direction, two or more rows of wire cross-sections aligned in the axial direction are stacked. When the radially innermost row is a first row and a row immediately outside the innermost row in the radial direction is a second row, the number of the cross-sections of the wire in the first row is less than that in the second row. An inner end of the second row is axially inward of a line drawn from an inner end of the first row and is perpendicular to a direction in which the first row extends. In the cross-section of the core taken at a plane perpendicular to the circumferential direction, an angle between a bottom side of the core and a bead base line is 2° to not greater than 9°.

  • Publication number: 20160243901
    Abstract: [Object] A pneumatic tire 2 that allows prevention of rim slip and separation from rim and that can be easily fitted, is provided. [Solution] In the tire 2, in a cross-section of a core 16 of a bead 8 taken at a plane perpendicular to the circumferential direction, two or more rows of wire cross-sections 26 aligned almost in the axial direction are stacked. When, of the rows, the radially innermost row is a first row, and a row immediately outside the innermost row in the radial direction is a second row, the number of the cross-sections 26 of the wire in the first row is less than the number of the cross-sections 26 of the wire in the second row. An inner end E2 of the second row is located axially inward of a line that is drawn from an inner end E1 of the first row and that is perpendicular to a direction in which the first row extends.

  • Patent number: 4167701
    Abstract: An error correcting decoder is disclosed which blocks correction of bits received during periods of relatively high signal intensity levels. A syndrome register and decision circuit provide error correcting bits for all bits which the sequence of input data determines to be in error. But only those data bits which occur during low levels of signal intensity are corrected.
