Long Run

Portable electronic devices are very popular nowadays. Almost all portable devices are battery powered, meaning that eventually, they all must be recharged–using the wired chargers currently being used. As the usage of these portable electronic devices is increasing, the demands for longer battery life are also increasing. These batteries need to be recharged or replaced periodically. It is a hassle to charge or change the battery after a while, especially when there is no power outlet around. Now instead of plugging in a cell phone, Personal Digital Assistant (PDA), digital camera, voice recorder, mp3 player or laptop to recharge it, it could receive its power wirelessly. The technology for Wireless Power Transmission or Wireless Power Transfer or Transmission (WPT) is in the forefront of electronic development. WPT systems are designed to transmit power without using wires more efficient than transmitting it while using wires. There could be large number of applications for wireless power systems. Hence, in this work, a wireless battery charger has been proposed for mobile phone charging which is expected to eliminate all the hassles with today’s battery technology. The advantage of this device is that it can wirelessly charge up the batteries which can save time and money in a long run for the general public.

ABSTRACT Wireless power transmission has been recently used to charge batteries in portable devices. This is the first study to combine this technology with light-emitting diodes (WPT-LP) for plant tissue culture application. We also present the comparison of the in vitro growth of chrysanthemum and strawberry plantlets under the new LED lighting system; LED - Uni-Pack (LP) system; LED tube and fluorescent light (FL). The results showed that fresh weight (1.42 g), dry weight (118.67 mg), plant height (5.68 cm), leaf area (3.59 cm2) and chlorophyll content (47.9 μg g-1) of chrysanthemum plantlets under the WPT-LP system were higher than those under FL and LED tube. Similar results were also recorded on the strawberry plantlets. Our results suggested that utilizing WPT-LP system saves the culture space considerably compared with the conventional downward lighting system with fluorescent lamps. The results also indicated that the subsequent growth and development of chrysanthemum and strawberry plantlets derived from WPT-LP system were either equal to or better than those from LP system under LED tube or FL.

Electronic devices are increasing rapidly nowadays. Today maximum electronic devices are operated on battery. They all need to be charge frequently to restore their working. In present day wired chargers are used for charging all electronic devices. Use of electronic devices is increasing rapidly, due to that long battery life is become today’s need. It is required to empowered batteries once in a while. When there is no electrical fitting around, it is not possible to charge or change the battery. The expansion for Wireless Energy Transmission or Wireless Power Transmission/Transfer (WPT) is increased electronic progression. WPT systems are used to transmit power/ (electronic energy) without using wires. Remote information transfer is expected to have tremendous applications in future. Distributed system gives remote information and energy access to all electronic devices simultaneously. We study a multiuser numerous information single-yield communicate framework and build a multi-receiving wire passage sends remote verification and Power. Authorised user can access the power transmitted by Transmitter. Distributed power transmission reduces with increase in distance. Bandwidth remains same up to certain distance.
