Abstract Even though their capacities are still orders of mag- nitude lower than those of hard disks, flash storage sys- tems are rapidly gaining importance in energy-constrained systems. This paper focuses on USB flash drives, which can provide portable storage to mobile systems or stor- age to systems that otherwise do not have persistent stor- age opportunities (e.g., low-power sensor devices). The paper presents studies relating to power consumption, en- ergy overheads and benefits, and performance impacts of USB flash drives. The key insig ....etc

CHAIN DRIVES IN LOW TORQUE DRIVES AND REDUCING PULSATIONS
INTRODUCTION TO DRIVES

Mechanical components used for power transmission. It may be belt, chain or gear depending on engine design parameters like - Distance between crankshaft and camshaft, engine maximum speed, engine-torque and engine construction cost. - Power transmission is done from one shaft to another shaft which may or may not rotate at same speed.

difference between chopper fed drives and converter fed drives pdf

If the source of supply is d.c. (for example in a battery vehicle or a rapid transit system) a chopper-type converter is usually employed. The basic operation of a single-switch chopper was discussed in topic 2, where it was shown that the average output voltage could be varied by periodically switching the battery voltage on and of for varying intervals. The principal difference between the thyristor-controlled rectifier and the chopper is that in the former the motor current ....etc

Kim Kardashian has revealed that she intended to start trying for babies just four weeks before she decided to split from her NBA husband Kris Humphries. The pair brought an end to their marriage after just 72 days, and it has been one of the biggest talking point in recent times. Many have been criticising Kim Kardashian by saying that the whole marriage was a setup. However, the TV reality star has revealed that she badly wanted to have some babies, and that they were about to try for the same just weeks before splitting.
One of the main re ....etc

USB EXPLAINED: AN INTRODUCTION TO USB AND ITS FUTURE


USB HISTORY
The Universal Serial Bus (USB) was introduced to the world of PC computing to solve the growing problem of how
to connect peripherals to a PC. The world of desktop computers needed a way, not only to physically connect
devices, but also allow them to be identified and categorized to enable a simple ease of use and method of discovery.
Prior to USB, many people overloaded the use of their serial and parallel ports to supp ....etc

Tape Drives is a device which is similar to a tape recorder, which reads data and writes it into a tape. The tape drives are the greatest backup medium which is suitable for regular PC user, but we must get the right type and use it properly. main benefit of a tape drive backup is that these tapes have a large capacity for storing data and are very inexpensive when compared to the cost of hard disk storage. Tape drives are used to store the data which is stored in hard drives and a tape drive is also known as a streamer that reads and writes da ....etc

A battery charger, or recharger, is a device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it.

The charging protocol depends on the size and type of the battery being charged. Some battery types have high tolerance for overcharging and can be recharged by connection to a constant voltage source or a constant current source; simple chargers of this type require manual disconnection at the end of the charge cycle, or may have a timer to cut off charging current at a fixed time. Ot ....etc

A Linux Device Driver for USB to USB Direct Link Device

The first version of the Universal Serial Bus (USB) specification was released in January 1996. In April 2000, version 2.0 of the USB specification, which supports transfer rates up to 480 Mbps, was released. Because of its low cost, high data-transfer rate, ease of use, and flexibility, USB has gained wide acceptance in the computer industry. Today, many peripherals and devices connect to computers through USB interfaces. Currently, most general-purpose operating systems pro ....etc
