  • Patent number: 11474014
    Abstract: A hand tool edge tester for evaluating the sharpness and smoothness of the cutting edge of a blade for the hand tool like a knife is provided according to the invention. The knife blade is held stationary along a horizontal, longitudinal axis. A long piece of solid tape of the cuttable substrate material like Teflon moved within a reel-to-reel tape mechanism attached to a tape carriage travels simultaneously horizontally as the tape carriage moves along a longitudinal axis, and along an upwardly inclined, diagonal pathway defined by the reel-to-reel mechanism. The blade of the hand tool slices the upwardly, diagonally moving tape ribbon with the load cell measuring the cutting force exerted by the tape ribbon against the blade as it is moved along the distance of the cutting edge substantially between the hand tool handle and the blade tip.

  • Patent number: 11442078
    Abstract: A mounting direction determination device and a mounting direction determination method of an acceleration sensor which can automatically determine the direction of the acceleration sensor mounted on a vehicle. The mounting direction determination device determines a mounting direction, relative to a vehicle, of the acceleration sensor that is capable of detecting a first acceleration in a first direction and a second acceleration in a second direction. A mounting direction determination unit determines the mounting direction by comparing values actually measured by the acceleration sensor with determination reference data. The determination reference data specifies a combination of the detection results of the first acceleration and the second acceleration and the mounting directions.

  • Patent number: 11442077
    Abstract: The present invention relates to capacitive micromechanical accelerometers, and in particular to acceleration sensors with movable rotors which may rotate out of a substrate plane when the accelerometer undergoes movement with an acceleration component perpendicular to the substrate plane. The capacitive micromechanical accelerometer includes additional damping springs to reduce unwanted movement of the rotor in the substrate plane, thereby reducing the parasitic capacitance that results from motion of the rotor in the substrate plane. The damping springs are vertically recessed with respect to other components of the accelerometer in order to minimise the effect of the damping springs on movement of the rotor out of the substrate plane.
