  • Patent number: 9612875
    Abstract: The present invention provides an operational-task-oriented system and method for dynamically adjusting operational environment applicable to a computer cluster. Each operational node of the computer cluster has two or more operational systems installed. After receiving the operational task, the control node estimates the time required for completing different tasks requiring different operational systems by appropriate operational nodes and compares the estimated finish time and the assigned finish time for judging how to adjust the operating system running in the operational nodes. Thereby, the operational task can be completed in the assigned finish time. Another method is to use the control node to analyze the proportions of the tasks requiring different operational systems in an operational task and hence adjusts the operational system running in an operational node according to the proportion of requirement. Thereby, the operational task can be completed in the shortest time.

  • Patent number: 8359559
    Abstract: Methods and systems for evaluating checker quality of a verification environment are provided. In some embodiments, an overall sensitivity for the verification environment and an individual sensitivity for a respective checker are calculated. The overall sensitivity is a probability that a plurality of problematic design behaviors, which are propagated to a checker system including at least one checker, can be detected by the verification environment. The individual sensitivity is a probability that a plurality of problematic design behaviors, which are propagated to at least one specific probe among a plurality of probes of a design, can be detected by the checker corresponding to the specific probe. The overall checker sensitivity numbers can show the robustness of the check system. The individual checker sensitivity can guide the user which individual checker or checkers to improve.

  • Patent number: 8085694
    Abstract: A method for avoiding unnecessary excessive stay of short cycle in discontinuous reception mechanism begins by using the short cycle while the short cycle timer is running. Then, it determines whether the inactivity timer expires or not and whether the short cycle timer expires or not. If the inactivity timer expires but the short cycle timer does not expire, the short cycle is used. If the short cycle timer expires but the inactivity timer does not expire, the long cycle is used. If the inactivity timer and the short cycle timer expire at the same time, either the short cycle or the long cycle is selected for use.

  • Patent number: 6067692
    Abstract: A micro-adjustable belt structure including a belt head, a micro-adjusting strap, a micro-adjuster and a clip buckle. The micro-adjuster is formed with a dent in which a magnet is fixedly disposed. The clip buckle is also formed with a dent in which a magnetic member such as an iron plate is fixedly disposed corresponding to the magnet. The clip buckle is made of a non-magnetic material. The magnetic member is covered by a protective film for protecting the magnetic member from being rusted.
