The purpose of this research is to implement hydraulics system and solar energy in The Tennis Balls Collecting Machine. The machine is operated with power of motor from solar cell energy. The canvas conveying belt is connected to the motor for carrying tennis balls to the basket. Hydraulics system lifts a tennis ball basket for releasing tennis balls to tennis ball keeping basket. The capacity of...
This paper describes the development of a solar powered wireless landfill monitoring system. A remote data acquisition system was constructed for collecting data on the temperature and gas concentration in a mini landfill setup. The data acquisition setup is powered by solar power and data transmission conducted wirelessly. The system consists of temperature and methane sensors, wireless data acquisition...
At the telecom service providers' installations, the problem of poor grid electricity supply is tackled by using diesel generators. These generators, however, entail a major problem in transportation and storage of diesel with noise pollution. Decentralized distributed generation technologies based on renewable energy resources such as solar photo voltaic (SPV) or/and wind turbine generators (WTG)...
IEEE 802.11 access point (AP) power saving is an important feature for solar/battery powered ESS mesh networks. In this paper we propose a media access control (MAC) protocol for power-aware multihop infrastructure, based on extensions to IEEE 802.11(e). A power saving mesh AP includes a network allocation map (NAM) in its beacon broadcasts which specifies its temporal operation, and thus coordinates...
