Abstract: A vacuum insulated glazing can be manufactured using a variety of methods. In one embodiment, a glass substrate is patterned and etched to form recesses in the surface of the glass substrate. The recesses or etched areas form a chamber when the glass substrate is bonded to another glass substrate. In another embodiment, nanoparticles and/or microparticles that absorb laser light are positioned between two glass substrates and heated to bond the glass substrates together. In another embodiment, a tempered glass substrate is bonded to another glass substrate to form a chamber between the substrates. The curved edges of the tempered glass are removed to produce a flat vacuum insulated glazing.

Abstract: A tool incorporating a device that generates a light line on a work surface such as a wall is disclosed. The device includes a housing containing a self-leveling pendulum assembly and a light source that directs a light beam along a pathway. A redirection assembly, also contained in the housing, is capable of altering the pathway of the light beam prior to exiting the housing. In use, the device selectively generates a light line on the work surface in a desired direction.

Abstract: An assembly for generating light lines on a surface is disclosed. The assembly may include a first housing coupled to a second housing. The first housing includes the first housing may include a first light source and a second light source capable of generating intersecting light lines on the surface. The first housing, moreover, may be repositioned with respect to the second housing to reorient the light lines on the surface. The assembly may further include a pendulum assembly operable to self-level the light lines to create substantially vertical (plumb) and/or horizontal lines over a generally vertical surface such as a wall.

Abstract: A light line generating assembly is disclosed. The assembly includes a light generating unit and a base. The light generating unit produces intersecting light planes to form light lines on a surface. The light generating unit may further include level indicators for manual leveling of the light generating unit. The base is operable to repositionably receive the light generating unit such that the unit may be rotated with respect to the base. The base includes an attachment mechanism operable to connect the base to a supporting surface such as a wall or floor. The attachment mechanism is adjustable, and can be reoriented to permit the selective use of particular coupling devices/methods. Additionally, the light line generating assembly may include an adjustable measuring device (e.g., a protractor) moveably attached to the base.

Abstract: A measuring and leveling tool has a distance encoder which is movable along a surface. The tool determines a distance traveled by the measuring device. The distance traveled is displayed in a digital display. The tool includes a laser leveling device which may be self-leveling or may be leveled manually to provide a projected line.
