Abstract: A calibrated airflow sensor and monitoring method are provided. The monitoring method which includes: providing an airflow sensor 301 positioned. within an electronic system, such as within large server applications, the airflow sensor including at least one temperature sensor 400, 401 and a heater 402 associated with one temperature sensor of the at least one temperature sensor; calibrating, with the airflow sensor positioned within the electronic system, a duty cycle for use in powering the heater associated with the one temperature sensor; and providing a controller configured to use the calibrated duty cycle in powering the heater of the temperature sensor during airflow monitoring of the electronic system, and to obtain a hot temperature (T hot) reading from the one temperature sensor having the associated heater, and to determine, based at least in part on the hot temperature (T hot) reading, whether to issue an airflow warning.

Abstract: Es werden ein Verfahren, ein System und ein Computerprogrammprodukt zum seriellen Übertragen von Prozessorbefehlen unterschiedlicher Ausführungspriorität beschrieben. Zum Beispiel empfängt ein Front-End-Prozessor seriell Prozessorbefehle. Eine mit dem Front-End-Prozessor verbundene Warteschlange niedriger Priorität speichert Befehle niedriger Priorität, und eine mit dem Front-End-Prozessor verbundene Warteschlange hoher Priorität speichert Befehle hoher Priorität. Ein Controller gibt die Übertragung von Befehlen entweder von der Warteschlange niedriger Priorität oder von der Warteschlange hoher Priorität zum Ausführen frei.

Abstract: A calibrated airflow monitoring method is provided. The monitoring method which includes: providing an airflow sensor positioned within an electronic system to be at least partially air-cooled, the airflow sensor including at least one temperature sensor and a heater associated with one temperature sensor of the at least one temperature sensor; calibrating, with the airflow sensor positioned within the electronic system, a duty cycle for use in powering the heater associated with the one temperature sensor; and providing a controller configured to use the calibrated duty cycle in powering the heater of the temperature sensor during airflow monitoring of the electronic system, and to obtain a hot temperature (Thot) reading from the one temperature sensor having the associated heater, and to determine, based at least in part on the hot temperature (Thot) reading, whether to issue an airflow warning.
