Patent JP-2002525694-A (JP)
IPC: G03B37/04
Filed: 1999-09-23
Abstract: The present invention overcomes many of the disadvantages of the prior art by providing a display that can be calibrated and re-calibrated with a minimal amount of manual intervention. To accomplish this, the present invention provides one or more cameras to capture an image that is projected on a display screen. In one embodiment, the one or more cameras are placed on the same side of the screen as the projectors. In another embodiment, an array of cameras is provided on either or both sides of the screen for capturing a number of adjacent and/or overlapping capture images of the screen. In either of these embodiments, the resulting capture images are processed to identify any non-desirable characteristics including any visible artifacts such as seams, bands, rings, etc. Once the non-desirable characteristics are identified, an appropriate transformation function is determined. The transformation function is used to pre-warp the input video signal to the display such that the non-desirable characteristics are reduced or eliminated from the display. The transformation function preferably compensates for spatial non-uniformity, color non-uniformity, luminance non-uniformity, and/or other visible artifacts.

IPC: C23C4/129
Filed: 1999-10-05
Abstract: The invention relates to a method for spraying of a material, wherein at least two different components are introduced into a flame (9) formed by means of fuel gas in such a way that the components react with each other, forming multicomponent glass particles. By means of the flame (9), the multicomponent glass particles are sprayed to a desired target. The first component is introduced to the flame as a gas or a vapour, and the second component is introduced into the flame in liquid form and is atomized by means of gas substantially in the vicinity of the flame. The first and second components are supplied into the flame (9) with the same device as the fuel gas. The liquid component and the gaseous component are formed into particles having the size in the order of magnitude of a nanometre and their mutual reaction is effected in such a way that homogeneous multicomponent glass particles are formed.

Patent JP-2002531361-A (JP)
IPC: B01J19/12
Filed: 1999-11-23
Abstract: A method for making a marking which is located beneath the surface of a glass body, in which the glass has a transmission curve with a plateau area at wavelengths which are longer than those of X-rays. A laser beam is directed onto a surface of the body. The laser beam can penetrate the body to a predetermined depth of the marking and is focused at the predetermined place of the marking inside the glass. The laser beam has a power density high enough to mark this location, essentially without changing the surface of the glass body in any perceptible way. The method is characterized in that a wavelength of the laser is used which makes the glass partially translucent and which is shorter than all the wavelengths of the laser light corresponding to the plateau area of the respective transmission curve. Using this method, very fine markings can be produced spaced a small distance underneath the surface of the glass body.
