The service center is also connected to the mobile systems of technicians who work for the field service organization by a mobile communications system such as a wireless Internet service provider. One or more message queues may be used to increase the reliability of communications between the systems. By using such a queue, messages may not be lost and the communications can be made transparent to the user of the remote system.

Abstract: The light-guiding apparatus has a light tunnel and an ellipsoidal reflector. Light emitted from the light tunnel is reflected and focused on a DMD chip by the ellipsoidal reflector. The light tunnel and a long axis of the ellipsoidal reflector form an angle. The angle and an eccentricity of the ellipsoidal reflector are used to modify the light emitted from the light tunnel. Thus, the light is made to match an incident angle and an effective dimension of a digital micro-mirror device receiving the light.

Abstract: A printer driving method for fast release of control privilege provides a printer processor processing a render module and a filter module in the background. After processing the print command by an application program, a printer driver converts the print command of an output object into a particular meta file using a kind of printer language. Meanwhile, the meta file is submitted to the printer processor in the background and the control privilege is released to the application program at the same time. Thereby, the operation system has enhanced efficiency since the application program will not be suspended during the printing process.

Abstract: A method of planarizing a non-conformal HPDCVD STI oxide isolation using an underlying first nitride layer and an overlying second nitride polish stop layer. The HPDCVD oxide is deposited so that the second nitride polish stop is formed coplanar with the first nitride layer over the center of narrow trenches. Both first and second nitride layers act as polish stops. The invention forms a first nitride layer over the substrate. Wide and narrow trenches are then etched in the substrate. In an important step, a non-conformal HDPCVD oxide layer is formed filling the trenches to a level about 500 .ANG. above the substrate surface. Then a second nitride layer is formed over the non-conformal HDPCVD oxide layer. Next, the structure is chemical-mechanical polished using both the first and nitride layers as polish stops. The second nitride layer and narrow extruded parts of the HDP-CVD oxide layer are removed in a DHF etch. Next, the first nitride layer is removed.
