Abstract: A tile-cutting measurement device includes a telescoping elongated body. The telescoping elongated body has a first distal end and a second distal end. A tile marker holder is disposed on the second distal end substantially parallel to the elongated body. The tile marker holder holds a tile marker. The first distal end of the tile-cutting measurement device is placed against a vertical surface such as a wall. When the tile-cutting measurement device travels along the wall, the marker traces a line along a loose tile to be cut that corresponds to the contours of the vertical surface. After the tile is measured in this manner, it will be cut along the line. The cut side of the tile is then fitted along the vertical surface. Advantageously, the tile-cutting measurement device is a portable and easy-to-use tool that allows for precise tile cutting measurements.

Abstract: Implementations disclosed herein provide a method comprising emitting light at a plurality of locations across a surface of a recording head assembly, detecting, using a detector not positioned along a waveguide axis, light output from a diffraction grating positioned along the waveguide axis, and determining a target position for mounting a laser source on the surface a recording head assembly by analyzing the detected light output corresponding to one or more of the plurality of locations.

Abstract: A method for measuring the coordinates of workplaces on a coordinate-measuring device has a probe head including a probe and a probe sensor associated therewith. The method includes generating a probe signal when the probe contacts a workpiece. From this signal, dimensional values are determined that represent the position of the probe head when the workpiece is contacted. The probe head additionally includes an acceleration sensor generating an acceleration signal when the probe head accelerates, wherein the probe signal and the acceleration signal are fed to a control and analysis unit for analysis. This unit determines the dimensional values so that an analysis signal is determined by subtracting the probe signal and the acceleration signal from each other, and the dimensional values representing the position of the probe head when contacting the workpiece are determined only using the analysis signal.

Abstract: A geometrical layout tool and method for locating a plurality of target points spaced apart over a particular area from a single reference point located within that area which is defined by the intersection of mutually perpendicular lines. A template placed over these lines has a central opening at the intersection and indicia at its periphery which register respectively with the lines. A center anchoring pin holds the template against movement, and a target line indicator is rotatably adjustable about the pin for alignment with a selected target point. A chalk line and tape measure or a laser may be mounted on the pin to make direction and distance determinations of the selected target point from the reference point.

Abstract: An electrical box locator for locating at least one electrical box on a stud, which electrical box locator includes a base plate and a pair of fixed stud flanges for engaging the stud; at least one stationary flange provided on the base plate for engaging a first end of an electrical box; and at least one adjustable flange adjustably carried by the base plate for engaging a second end of the electrical box.

Abstract: A device for estimating the length of the floor covering needed from a roll of floor covering having a predetermined width to cover a room, including any fill area based on a scale diagram of the room showing walls bounding the room. The device comprises a generally planar body having an upper surface and opposing lower surface for contacting the diagram. A first positioning guide is provided on the body for aligning the body on the diagram about a first direction. A second positioning guide is provided on the body for aligning the body on the diagram about a second direction. Floor covering width and length indicia are provided on the body along the first and second axes, respectively. A fill width indicia is provided on the body and corresponds to the first direction. A data matrix comprising multiple cells is defined by the intersection of the fill width indicia and the floor covering length indicia.

Abstract: A collar for a drain pipe riser is provided for maintaining an annular space about the periphery of the riser during the pouring of a floor about the riser. The collar includes inner and outer sleeves separated by a plurality of knock-out webs. The inner sleeve is adapted to fit over the riser while the outer sleeve insures an annular space will be maintained about the riser during pouring of the floor. The webs can then be knocked out, and the inner sleeve and webs removed.

Abstract: Each unit of an array of submerged oceanographic devices is provided with a depth gauge of the air bubbler type. A typical depth gauge consists of a tube or air line that has one end fluidly coupled to a manifold; the other end of the air line is open. The open end of the air line is secured adjacent a corresponding submerged device. A small flow of air is established from the manifold, through the air line, to bubble out the open end into the water. A pressure transducer is fluidly coupled to the air line and senses the backpressure due to the hydrostatic water head existing above the submerged device. Means are provided for inhibiting pneumatic cross feed in the manifold between the respective air lines.
