Title: System and method for obtaining clock recovery from a received data signal
Inventor: SCHOLTZ WILLIAM H
IPC: H04L7/027
Filed: 1998-08-25
Granted: 2001-03-11
Abstract: A system for the evaluation of a timing vector to determine whether reliable timing recovery may be established at a predetermined center frequency, or from a specific pilot tone in the received signal. According to the present invention, the timing vector is created using band edge filters, a pilot tone timing recovery band pass filter, or other suitable means. The timing vector is then sampled a predetermined number of times. The sampled timing vectors are plotted on a complex plane to evaluate the general distribution of the sampled timing vectors. Timing recovery is then established using an acceptable timing vector as determined by comparing the distribution of the sampled vectors with a predetermined distribution threshold. In particular, a narrow distribution indicates minimum of signal noise, interference, or disruption, whereas a wide distribution indicates the opposite. The instant invention also includes a means of evaluating the timing vector at several center frequencies in the case of band edge timing recover until an acceptable timing vector is found.

Title: Improved LCD with wide viewing angle
Inventor: WEI JUNG-GUANG
IPC: G02F1/13
Filed: 1998-08-04
Granted: 2001-02-01
Abstract: A method for manufacturing a liquid crystal display having both wide angle viewing and fast response is described. A key feature of the method is the addition to the liquid crystal of a small amount of a monomer, selected from among the diacrylates or the monoacrylates, as well as a chiral dopant. Once the display has been assembled, the usual turn-on voltage (about 5 volts) is applied. After allowing the orientations of the directors to stabilize, the liquid crystal is irradiated with ultraviolet light for a few seconds. This causes the dissolved monomer to polymerize in place. The UV irradiation and applied voltage are then terminated. Defects that slow down the director stabilization are now prevented from re-forming so that the next time voltage is applied, the system responds in a few milliseconds. Adding a photoinitiator, in addition to the monomer, is an option.

Title: Manufacturing process of copper structure
Inventor: LI TZ-LIANG
IPC: H01L21/768
Filed: 2000-04-21
Granted: 2001-10-01
Abstract: This invention provides a manufacturing process to form a dual damascene opening in a composite insulation layers for dual damascene copper structure. This process is characterized by the use of a composite insulation layer of silicon oxide layer and multiple silicon nitride stop layers, using anisotropic reactive ion etching on the composite insulation layer to form the dual damascene opening. The increase in capacitance is minimized by reducing the thickness of the multiple silicon nitride stop layers to an extreme extent without sacrificing their function as etching stop layers. The dual damascene copper structure can reduce the RC delay effectively due to the better conductivity of copper and thinner silicon nitride stop layers in the composite insulation layer.
