Title: Heat dissipating box
Inventor: DAHL UNO
IPC: H05K7/14
Filed: 1998-03-03
Abstract: The present invention relates to a heat dissipating box for a printed board assembly (PBA) using natural convection for cooling. The PBA 64 is fastened between a first part 62 and a second part 61 and the joint is sealed with an elastic material  71.  A back plane,  which  has  an  opening  for  a connector of the PBA, is mounted to the other two parts to prevent undesirable substances to get inside the box.  The heat dissipating property of the PBA, mounted inside a box, increases rapidly if the PBA's heat dissipating components are placed near or in good thermal contact with the box. This can be obtained by placing bumps, for example supports 66, 68 or ridges 65, on the inside of the box, which are in close contact with the PBA. The surface area of the box may also be enlarged with cooling fins.

Title: Paper quality determination and control using scale of formation data
Inventor: DOUGLAS W J MURRAY
IPC: G07C3/14
Filed: 1998-10-01
Abstract: A quality of a sheet material, such as unprinted paper, is determined by acquiring an image of the surface of the sheet material and analyzing the image to determine the intensity of local nonuniformity as a function of scale of formation. A meaningful interpretation of the sheet material quality is possible using the scale of formation. Correlations between sheet material qualities, such as cloudiness, cross-directional strength, etc., and the scale of formation allow for rapidly acquired images to provide useful indicators of sheet material quality. Normalizing the sheet material formation line with respect to a desired standard sheet allows for a useful graphical display of the sheet material quality.
