  • Patent number: 7276440
    Abstract: In accordance with the objectives of the invention a new design and method for the implementation thereof is provided in the form of an “oxide ring”. A conventional die is provided with a guard ring or sealing ring, which surrounds and isolates the active surface area of an individual semiconductor die. The “oxide ring” of the invention surrounds the guard ring or sealing ring and forms in this manner a mechanical stress release buffer between the sawing paths of the die and the active surface area of the singulated individual semiconductor die.

  • Patent number: 7210053
    Abstract: One or more derived timers based on a source timer are provided to accommodate a plurality of periodic tasks while maintaining the high resolution of the source timer. To accommodate a number of periodic tasks, a number of derived timers can be selected utilizing a novel method based on the number of periodic tasks that are most time-critical, the number of tasks that are less time-critical, and the number of tasks that can be performed during the source timer interval. The interval and start time for each derived timer is selected based the source timer and number of the derived timer. After establishing the derived timers, the most time-critical tasks can be assigned to the source timer and the less time-critical tasks arranged amongst the derived timers.

  • Publication number: 20070082884
    Abstract: Inhibition of protein kinases having one or more cysteine residues within the ATP binding site is effected by contacting the kinase, per se or in a cell or subject, with an inhibitory-effective amount of a compound having a heterocyclic core structure comprised of two or more fused rings containing at least one nitrogen ring atom, and an electrophilic substituent that is capable of reacting with a cysteine residue within the ATP binding site of a kinase. Preferred compounds include certain pyrrolopyrimidines and oxindoles having such an electrophilic substituent and optionally an aromatic or heteroaromatic substituent that is capable of interacting with a threonine or smaller residue located in the gatekeeper position of the kinase. Kinases lacking such cysteine residues may be engineered or modified so that they are capable of being inhibited by such compounds by replacing a valine or other amino acid residue within the ATP binding site by a cysteine residue.
