    • Embodiments for at least one method and apparatus of generating a regulated voltage are disclosed. One method includes generating the regulated voltage though controlled closing and opening of a series switch element and shunt switch element, the series switch element being connected between a first voltage supply and a common node, and the shunt switch being connected between the common node and a second supply voltage. The series switch element includes an NMOS series switching transistor stacked with an NMOS series protection transistor, and closing the series switch element during a first period includes applying a switching gate voltage to a gate of the NMOS series switch transistor of the series switch element, wherein the switching gate voltage has a voltage potential of at least a threshold voltage greater than a voltage potential of the common node. The shunt switch element includes an NMOS shunt switching transistor stacked with an NMOS shunt protection transistor, and the shunt switch element is closed during a second period.

    • Provided is a method for scheduling activities. The method includes receiving an activity having a designated priority, a life span, a preferred implementation time, and a scheduling time budget. The schedule is searched to determine the availability of the preferred implementation time and amount of available execution time. The activity is inserted in the schedule if the preferred implementation time if the time is available and life span is less than or equal to available execution time. If the implementation time is unavailable or the life span is greater than the available execution time, the schedule is modified. Modification of the schedule preserves scheduled activities with equal or higher priority. The method will exit when the activity is scheduled or the elapsed scheduling time exceeds the scheduling time budget.
    • 提供了一种调度活动的方法。 该方法包括接收具有指定优先级,寿命,优选实施时间和调度时间预算的活动。 搜索时间表以确定优选执行时间和可用执行时间量的可用性。 如果时间可用,寿命小于或等于可用执行时间,则优先执行时间将插入活动。 如果执行时间不可用或寿命大于可用执行时间,则修改日程表。 修改时间表保持等同或更高优先级的预定活动。 该方法将在活动计划或过程调度时间超过调度时间预算时退出。
