  • Blade assembly for a lawn mower
    Patent number: 11937545
    Abstract: A lawn mower includes a blade assembly configured to perform a cutting function. The blade assembly includes an upper blade mounted about a blade rotation axis and an upper blade proximal portion being substantially flat and including a first cutting edge. A lower blade is mounted in overlap with the upper blade about the blade rotation axis. The lower blade includes a lower blade proximal portion positioned outward from the lower blade mounting portion in a radial direction, a lower blade end portion positioned outward from the lower blade proximal portion and below the lower blade proximal portion, and a second cutting edge. A lower blade falling portion transitions from the lower blade proximal portion to the lower blade end portion.
    Type: Grant

  • Method and apparatus for evaluating accuracy in positioning a receiver point
    Patent number: 11493595
    Abstract: A method for evaluating accuracy in positioning a receiver point, which is associated with at least one shot point, and for which a derived position data is obtained, wherein a pair of the receiver point and a respective shot point is associated with a characteristic parameter which includes an offset, a velocity of first arrival wave and a first arrival time, the method comprising: step S10, constructing a residual vector associated with the receiver point and the respective shot point based on the characteristic parameter; step S12, determining a characterization parameter of the derived position data based on the residual vector; and step S14, evaluating accuracy of the derived position data based on the characterization parameter. An apparatus for evaluating accuracy in positioning a receiver point is also provided.
