Energy saving and power saving are the basic requirement in this world. Power sources such as non-renewable & renewable sources are available but still energy and power disaster cannot be overcome. In this paper, one of the non conventional methods has been discussed known as walking or running on the footstep. Non-conventional method that is from foot step, kinetic energy from foot step is con...

The total power consumption of all semiconductor plants exceeds 100 million kWh per year, with about 43% of this consumption to operate air conditioning facilities. This high power consumption is due to the requirement of the cleanliness kept for clean rooms, with extremely high power consumed to the air transferring power. Oki developed the fan module unit (FMU) type air conditioning system to...

Power-saving is a critical issue for almost all kinds of portable devices. In this paper, we consider the design of power-saving protocols for mobile ad hoc networks (MANETs) that allow mobile hosts to switch to a low-power sleep mode. The MANETs being considered in this paper are characterized by unpredictable mobility, multi-hop communication, and no clock synchronization mechanism. In partic...

Practically, clocking system like flip-flop (FF) consumes large portion of total chip power. In this paper, a novel low-power pulse-triggered flip-flop (FF) design is presented. Pulsetriggered FF (P-FF) has been considered as a popular alternative to the conventional master –slave based FF in the applications of high speed. First, a simple two-transistor AND gate design is used to reduce the ci...

Abstract. Power management is one of the most important issues in mobile communications. Much research has been done in reducing wireless station’s power consumptions. IEEE 802.11 addresses this issue by adopting a MAC layer active-doze Power Saving Mechanism. In an 802.11 ad hoc network, this Power Saving Mechanism works as follows. Any wireless station with data to send must first announce it...

Last level caches (LLCs) contribute significantly to processor power consumption. Saving LLC energy in multicore QoS systems is especially challenging, since aggressive energy saving techniques may lead to failure in providing QoS. We present MANAGER, a multicore shared cache energy saving technique for quality-of-service systems. Using dynamic profiling, MANAGER periodically predicts cache acc...

The study examines the effect of transformation ratio in power transmission system on engine efficiency as a function of passenger vehicle velocity (m = 1400 kg) with energy-saving vehicle drive. The study also presents working range in driving phases for energy-saving speed control up to 120 km/h for a simplified overall engine performance map for SI engine. Understanding of the presented cons...
