Abstract: A clip for attachment to a suspended ceiling grid support member, the clip including a generally planar body portion having a first edge, a second edge opposite the first edge, a first end, and a second end opposite the first end. A first wing is positioned at the first edge and at the first end and a second wing is positioned at the second edge and at the second end. The first wing has spaced aligned apertures located outside of the first edge and the second wing has spaced aligned apertures located outside of the second edge for receipt of fasteners therethrough. The fasteners extend into ceiling panels or planks without contacting the suspended support member to which the clips are secured.

Abstract: Polygon reshaping methods either add or subtract sides of lines of a polygon around an object of a digitized frame of picture stock. A line may be added by selecting a line of a polygon and adding a point to the line, thereby defining two lines with the point as their vertex. The point may be move along the line and away from the line to create an angle between the two lines on either side of the vertex. A line may be subtracted from a polygon either by selecting a line of the polygon and simply deleting it or by selecting a vertex of the polygon and deleting the two lines which shared the vertex. In the former line-removal case, the now-free endpoints of the lines adjacent to the removed line are moved and connected at a point defined along the removed line. In the latter vertex-removal case, a new line is drawn between the now-free endpoints of the lines which were respectively adjacent the removed lines.

Abstract: Edge detection or region definition technology in picture colorization masks objects of a frame by identifying pixels in the frame which fall within a determined range of luminance values. A seed point is selected within an object to be masked, and a test area is generated around the seed point. The test area may be any arbitrary shape or size. A range of luminance values of the pixels in the test area is generated, with the boundary values of the range representing the pixels having the highest and lowest luminance values. Pixels within the object to be masked which have luminance values falling within the range are identified and highlighted. The boundary values of the range may then be adjusted depending upon the satisfaction of the colorist. A mask is then defined to comprise the identified and highlighted pixels.

Abstract: A soldering tool with a resilient hold-down attachment is described together with a manner of using the tool or a plurality of such tools to solder a braided lead wire to a bus bar fused to a glass substrate. Such tools are used to make heated backlights for automobiles.

Abstract: A device for continually sensing the temperature of an advancing glass ribbon has a thermocouple temperature sensing junction mounted within the area circumscribed by a pair of rotating wheels and spaced from the periphery of the wheels. The wheels engage the ribbon and are rotated thereby as the temperature sensing junction remains in a fixed position in a plane containing the rotating axis of the wheels and normal to the glass surface to continually sense the temperature of the advancing ribbon.
