A memory device includes a data array, a tag array, and control logic. The apparatus includes an owner storage controller; an IO performing component, an ownership assignment component, a lock manager and a messaging component. The method includes measuring an atmospheric condition associated with the environment surrounding the wind turbine, providing the measured atmospheric condition to a processor, and determining at least one monitor set point limit based at least partially on the measured atmospheric condition. The light is emitted in pulses in the preferred embodiment, and the optical sensing system has automated calibration and error detecting functions. The mobile device may perform an action in response to identifying a tag that satisfies a user preference. Pharmaceutical composition comprising these compounds, method of treating diseases mediated by Cathepsin B, utilizing these compounds and methods of preparing these compounds are also disclosed.
