Title: Trust negotiation in a client/server data processing network using automatic incremental credential disclosure
Inventor: SEAMONS KENT ELDON
IPC: H04L29/06
Filed: 2000-02-16
Granted: 2001-09-01
Abstract: In client/server computing, especially in the field of e-commerce, digitally signed credentials are passed between client and server to develop trust between the parties. However, this requires that one party disclose its credentials (which could be considered sensitive) to the other party before the disclosing party knows anything about the receiving party (someone has to go first). To solve this problem, the invention implements a negotiation of credential disclosure called automatic incremental credential disclosure. Each credential held at a local site is associated with an access policy which is based on opposing site credentials. Incoming requests for credentials are logically combined with the access policies to derive further negotiation responses.
Patent TW-567473-B (TW)
Title: Method and device for recording real-time information
Inventor: VAN NIEUWENHOVEN MARCEL STEFAN
IPC: G11B20/12
Filed: 2000-02-17
Granted: 2003-12-21
Abstract: In a method of recording real-time information on an information carrier, e.g. audio on an optical disc, the real-time information is compressed to units comprising a variable amount of compressed data, and playback parameters are determined in dependence of the compressed data. The playback parameters comprise an access list (Main_Acc_List) having entries, each subsequent entry being assigned to a subsequent interval of a fixed playback time and comprising a pointer (Entry[N]) to a unit within said interval. In a player the real-time information may be accessed at a selected point of playing time. The corresponding entry in the access list is determined by dividing the selected time by the interval. The entry provides the pointer (Entry[N]) to the unit corresponding to the selected playing time. Interpolation may be used for calculating an address at a selected playing time within an interval, and the accuracy may be improved by a margin parameter (Access_Flags[N]), which indicates the maximum distance between the unit of the selected playing time and the interpolated address.

Title: Flip chip bump bonding
Inventor: DEGANI YINON
IPC: H01L21/60
Filed: 2000-04-08
Granted: 2001-07-11
Abstract: The specification describes techniques for applying solder bumps to IC chips. The solder bump sites are first provided with under bump metallization (UBM) for solder bump interconnections to the AI bonding sites on the IC chip. The substrate, i.e. the capping layer of the IC chip, is coated with photoresist and patterned to expose the UBM and a peripheral portion of the capping layer around the UBM. The solder paste is then applied and reflowed to form the solder bump. Since the photoresist hardens and becomes difficult to remove after the reflow step, a sacrificial buffer layer is interposed between the photoresist and the capping layer to facilitate removal of the photoresist without attacking the IC chip surface.

Title: Rupture disk controlled mechanically actuated pressure relief valve assembly
Inventor: DEGOOD ROBERT L
IPC: F16K17/16
Filed: 2000-03-03
Granted: 2001-09-11
Abstract: Improved burst disk-type pressure responsive valve assemblies (20, 184) of the pressure relief and shutdown variety are provided which utilize frangible burst disks (30, 204) which largely determine the set point pressures for the valves. The assemblies (20, 184) include a housing (22, 186) having an inlet (24, 188), an outlet (26, 190) with a valve seat (28, 192) therein. The housing (22, 186) also supports a frangible burst disk (30, 204). An actuating unit (32, 210) within the housing (22, 186) includes a shiftable, pressure responsive piston (78, 212) supporting a valve stem actuator rod (82, 214); the rod (82, 214) is operatively coupled with a disk actuating element (84, 216) located adjacent a face of the rupture disk (30, 204). When an overpressure is sensed at the inlet (24, 188), the actuating unit (32, 210) serves to burst the disk (30, 204), allowing the piston (78, 212) to move relative to the valve seat (28, 192) to establish or close communication between the inlet (24, 188) and outlet (26, 190). The valve assemblies (20, 184) can be easily repaired or retrofitted in the field, without the need for extensive dismantling of conduits or the like. Use of disks (30, 204) which rupture during valve operation affords a visual indication of valve operation and permits fabrication of high capacity, long stroke length valves.

Title: Direct digital frequency synthesis enabling spur elimination
Inventor: SANDER WENDELL
IPC: H03L7/089
Filed: 2000-03-16
Granted: 2002-05-11
Abstract: The present invention, generally speaking, provides improved methods of generating clean, precisely-modulated waveforms, at least partly using digital techniques. In accordance with one aspect of the invention, a ""difference engine"" is provided that produces a digital signal representing the frequency error between a numeric frequency and an analog frequency. The frequency error may be digitally integrated to produce a digital signal representing the phase error. The difference engine may be incorporated into a PLL, where the analog frequency is that of an output signal of a VCO of the PLL. Direct modulation of the PLL output signal may be performed numerically. By further providing an auxiliary modulation path and performing calibration between the direction modulation path and the auxiliary modulation path, modulation characteristics may be separated from loop bandwidth constraints. In particular, the loop bandwidth of the PLL may be made so low as to reduce spurs (usually associated with DDS techniques) to an arbitrarily low level. A loop filter of the PLL may be realized in digital form. Using a digital loop filter would ordinarily require use of a high-resolution DAC. Various techniques are described for reducing the resolution requirements of the DAC.

Granted: 2003-03-21
Abstract: The purpose of the present invention is to provide a liquid-crystal panel capable of maintaining reliability of the wiring and having a high-density wiring. The solving means is described in the following. The odd-numbered scanning lines 312-1, 312-3, ..., 312-199 are connected to the first wiring group G1 while the even-numbered scanning lines 312-2, 312-4, ..., 312-200 are connected to the second wiring group G2. Each of the scanning lines 312-1 to 312-200 is supplied with a scanning signal whose polarity is inverted during every horizontal scanning period. Therefore, among the wirings 240 forming the first wiring group G1 and the second wiring group G2, a line-to-line voltage between any adjacent wirings becomes zero volts for most of the time. Consequently, degradation of the wirings due to electrolytic corrosion is suppressed even if the spacing between the wirings is narrowed.
