A vehicle measurement apparatus, includes a base module, a column module, and a crossbeam module, the column module being mounted on the base module, and the crossbeam module comprising a crossbeam, an adjustment mechanism and a fine-adjustment mechanism, wherein one end of the fine-adjustment mechanism is mounted on the column module, and the other end of the fine-adjustment mechanism is mounted on the adjustment mechanism; the crossbeam is mounted on the adjustment mechanism; the adjustment mechanism is configured to adjust the position of the crossbeam relative to the column module; and the fine-adjustment mechanism is configured to adjust the position of the adjustment mechanism relative to the column module. With the above structure, during the adjustment process, a user can adjust the position of the crossbeam only by means of the fine-adjustment mechanism and the adjustment mechanism.

An explosive matrix assembly of the present disclosure has a single detonating cord formed into a grid, and the grid comprises a first plurality of detonating cord portions lying in a first plane and a second plurality of detonating cord portions lying in a second plane and the first plurality of detonating cord portions perpendicularly overlay the second plurality of detonating portions. Additionally, the explosive matrix assembly has at least one insensitive blasting agent coupled to the grid.

A tile spacing tool is disclosed herein that spans a gap between tile rows where the gap is sized to receive a decorative insert or the like. The spacing tool spans the gap and transfers the weight of the upper tile rows across the gap to the lower tile rows, which are supported by a floor or ledge. As a result, the entire wall can be built including the decorative insert without waiting for the bottom tile rows to dry to support the weight of the tile rows above the decorative insert.

A pipe spacing wedge system including a pipe spacing wedge assembly, with the pipe spacing wedge assembly including a wedge-body. The wedge-body may be defined by a front-side, a back-side, a right-edge, a left-edge, a top-edge, and a bottom-edge. The front-side of the wedge-body includes a plurality of stepped surfaces and the top-edge includes a sharp point. The pipe spacing wedge assembly is structured and arranged to assist a user in setting a variety of specific gap-distance between sections of pipe and pipe spacing wedge assembly is intended to be driven between the two sections of pipe by the user to set the gap-distance.

A calibration plate and a method of calibrating a 3D measurement device is provided. The calibration plate includes a planar body having a surface. A plurality of marks are arranged on the surface. The plurality of marks being configured to be recorded by the camera and can be identified in the resulting recorded images during operation of the 3D measurement device. A mirror is positioned on the surface that reflects incident beams from the 3D measurement device.

Disclosed is a measurement device including a first measurement element including a base surface and an upper surface, the upper surface of the first measurement element spaced apart from the base surface of the first measurement element by a first height; and a second measurement element including a base surface and an upper surface, the upper surface of the second measurement element spaced apart from the base surface of the second measurement element by a second height, the second height greater than the first height and the second measurement element attached to the first measurement element. The measurement device can function as a spacer to gauge short distances such as when installing trim around a window or door casement or when installing cabinetry, tile, or siding.
