  • Publication number: 20110255566
    Abstract: A method for deriving precise control over laser power of an optical pickup unit (OPU) includes: providing an analog-to-digital converter (ADC) within an automatic power calibration (APC) circuit to derive a path gain and/or a path offset from the APC circuit; and selectively performing compensation according to the gain and/or the path offset, in order to maintain precision of a relationship between the laser power and a target command utilized for controlling the laser power. An associated APC circuit comprising an ADC and at least one compensation module is further provided. The ADC is utilized for deriving a path gain and/or a path offset from the APC circuit. The compensation module is utilized for selectively performing compensation according to the path gain and/or the path offset, in order to control the laser power by a target command.

  • Publication number: 20110137900
    Abstract: A computer implemented method, computer program product and data processing system, for identifying common structures shared across a plurality of formatted text documents. The common structure is presented as a sequence of landmarks, each of which has a starting and ending marker to describe the borders of text. The common structure is identified by counting the occurrences of repeating text segments across documents. Frequently co-occurred adjacent segments become candidates for markers of landmarks. In addition, styling information of textual content within a landmark is extracted and mapped to rules. The rules are used to merge and summarize content from multiple documents, which gives an advantage over current practice of content concatenation.

  • Publication number: 20100192005
    Abstract: A management system for a computer system is disclosed. The computer system operates or includes various products (e.g., software products) that can be managed in a management system or collectively by a group of management systems. Typically, the management system operates on a computer separate from the computer system being managed. The management system can make use of a knowledge base of causing symptoms for previously observed problems at other sites or computer systems. In other words, the knowledge base can built from and shared by different users across different products to leverage knowledge that is otherwise disparate. The knowledge base typically grows over time. The management system can use its ability to request information from the computer system being managed together with the knowledge base to infer a problem root cause in the computer system being managed.
