Abstract: An apparatus for forming horizontal and linear score at a predefined depth or adjustable depth in a plurality of curb sections or a similar concrete or masonry structure. The apparatus comprises a frame, two-axis of linear bearings guides, angle grinder, cutting blades, and protective shield. The frame is secured in the curb section or structure through stakes to penetrate a ground or slip into holes of a horizontal surface. The frame includes a plurality of first adjustment units to allow adjustments for heights according to the height of curb section, and second adjustment units to allow adjustments for depths according to the depth of the curb section. A horizontal linear bearing guide rides up and down on a vertical linear bearing guide and restricted by a height adjustment mechanism. The angle grinder hanged on a mount attached to the linear bearing. The protective shield covers the plurality of cutting blades and further attached to a water supply to provide a spray on the plurality of cutting blades.

Abstract: An apparatus in one example has: a first component coupled to a second component by a suspension component; and the suspension component structured to maintain predetermined angular spring rates and to maintain high linear spring rates, that are higher than the angular spring rates, along linear axes of the suspension component that flex under predetermined increased dynamic loading of the suspension component.

Abstract: A gyroscope assembly comprises a shaft and a flexure device mounted on the shaft. The flexure device includes three concentric plates. A first pair of diametrically opposed hinges connected the inner plate and the central plate. A second pair of diametrically opposed hinges spaced 90° apart from the first pair of hinges connects the outer plate and the inner plate. The hinges define two perpendicular sensing axis and form a gimbal so that rotations of the outer plate about the sensing axes may be detected.
