This topic introduces the concept of Hot Swapping DC power buses and why hotswapping has become a mainstream requirement, particularly in the telecommunications industry. Several methods of implementing hot swap will be provided along with the pros and cons of each method. Finally, a hot swap design utilizing a Hot Swap Power Manager will be presented for a typical -48V telecom

Energy consumption is a crucial factor for the lifetime of many embedded systems, especially wireless sensor networks. Most modern microcontrollers provide various low power sleep modes. Utilizing them can lead to great energy savings. In this paper we present an approach for power management in embedded systems, based on the event-driven operating system REFLEX. The implicit power management i...

In this paper, we present a strategy for run-time profiling to optimize the configuration of a superscalar microprocessor dynamically so as to save power with minimum-performance penalty. The configuration of the processor is changed according to the parallelism and power profile of the running application. To identify the optimal configuration, additional hardware with minimal overhead is used...

In most low-power systems, power management is generally thought of as being an ability to switch certain parts of a system off or put them in a low-power state when they are not required, and to manage the charging of a battery. While these are important aspects of low-power electronics powered by energy harvesters, there are much more fundamental reasons for requiring power electronics in an ...

In this study, the relationships between two variables: the strategy of sustainable development and the efficiency of waste management in the commercial power industry company have been subjected to discussion. The basis for the explanation of the aforementioned relationships is the assumption that the level of implementation of the strategy of sustainable development is expressed through capit...
