Title: Optical disc system having servo motor and servo error detection assembly operated relative to monitored quad sum signal
Inventor: CRUPPER RANDOLPH SCOTT
IPC: G11B7/125
Filed: 1996-03-02
Granted: 2000-05-01
Abstract: An optical disc system including a focusing mechanism and a tracking mechanism, wherein the mechanisms are controlled by feedback loops having electronic circuits for generating a servo error signals. The error signals are communicated in the feedback loop for effecting corrections of the focusing mechanism and the tracking mechanism. The optical disc system is provided with digital lead/lag compensation circuit assembly including a servo loop having servo loop transfer function and an error signal. The circuit assembly includes a motor or actuator having a mechanical resonance frequency being less than a predetermined sampling frequency and a compensation circuit for stabilizing the servo loop. The error signal of the servo loop is sampled at the pre-determined sampling frequency. Normalization of the error signals to the information signal occurs during sampling. The compensation circuit has a compensation transfer function including a single lead and a complex lag for producing a notch filter with a notch. The compensation transfer function is formulated so that the notch occurs at approximately one half the predetermined sampling frequency thereby reducing amplitude of the mechanical resonance frequency in the servo loop transfer function. The optical disc system also includes a mechanical isolator for vibration isolation and accommodation of thermal expansion, an oscillator with a tank circuit having an increased resistance, an improved focus capture system, and means for identifying blank sectors in a storage medium.

Title: Method for optimizing off-peak caching of web data
Inventor: THOMPSON JOSEPH RAYMOND
IPC: G06F17/30
Filed: 1998-02-09
Granted: 2002-08-21
Abstract: A method of retrieving Web content from a plurality of web servers for delivery to a Web client connectable to the World Wide Web via a communication link. The Web client is preferably a data processing system connectable to a television, or other conventional monitor to provide low cost internet access. The method begins by having the user define a set of one or more servers from which content is desired to be retrieved and stored in the cache. These servers are preferably identified by a ""list"" of favorite Web sites. A test is then made to determine whether a given download period has terminated. Typically, this download period occurs during an ""off"" period, such as in the middle of the night, to avoid traffic congestion at the Web server sites, if the given download period has not terminated, a determination is then made of an activity level for the communication link as content is being downloaded to the cache from the one or more servers. If the activity level for the communication link is less than a given threshold level, additional requests for content are issued to the cache according to a so-called ""fairness policy"" that ensures that content from as many sites as possible is downloaded during the download period.

Title: Method of detecting timing in changing filter
Inventor: CHEN CHUEN-JUNG
IPC: B01D35/00
Filed: 1998-10-22
Granted: 2001-02-21
Abstract: A method of detecting the timing in changing a filter according to the present invention comprises driving a liquid supply device at a detection speed higher than a specified speed (normal speed); detecting whether there is fluid ejected out of the nozzle; and replacing the filter if there is no fluid ejected out of the nozzle. Meanwhile, the method of setting the detection speed comprises driving the liquid supply device at the abovementioned specified speed and detecting the fluid ejected from the nozzle to a sprayed article until the occurrence of a defect in the fluid ejected; increasing the rotation speed of the liquid supply device until the nozzle stops ejecting the fluid, and then setting the speed of the liquid device at that time as the detection speed. Therefore, the method can accurately measure the timing in changing a filter thereby reducing the operation cost of a filter.

Title: Interposer for recessed flip-chip package
Inventor: DEGANI YINON
IPC: H01L23/498
Filed: 1999-08-11
Granted: 2001-02-21
Abstract: The specification describes a recessed chip IC package in which the IC chip is bonded to a silicon translator, and power and ground planes for IC power and ground interconnections are formed on separate interconnect levels of the translator. The multilevel interconnection capability of the translator allows crossovers, and allows power and ground pins from the IC chip to be both isolated from signal 1/Os, and consolidated into fewer interconnections going to the next board level. The thermal mismatch between the silicon translator and conventional printed wiring board materials is addressed by using an interposer which is essentially a ball grid array of plated-through holes that transfers the interconnect pattern from the translator to the printed wiring board. The interposer may have a composition with a coefficient of thermal expansion (CTE) that lies between the CTE of silicon and the CTE of the board material. It may also be provided with holes or slots for additional stress relief.
