Circuit protection for rechargeable lithium-based battery cells and packs is a critical design consideration. Overcurrent and overtemperature conditions that can result from accidental shorting or abusive/runaway charging can raise temperatures high enough to damage components and cause substantial equipment damage.
Early circuit-protection designs relied on fragile one-shot fuses to provide total current interruption for overcurrent protection. However, because the majority of fa ....etc

Storage performance increases using the interface (for example, 2 Gb or 4 Gb Fibre Channel) (FC), which connects the storage servers and storage devices on the array of switches and hubs a year to form the tissue that supports both re ....etc

PPTC circuit-protection devices are used to protect against harmful over current surges and over-temperature faults. Like traditional fuses, these limit the flow of dangerously high current during fault conditions. The PPTC device, however, automatically resets after the fault is cleared and power to the circuit is removed. Understanding the precise nature of these devices can help designers develop more reliable equipment and reduce warranty, service and repair costs. Improvements in size, cost and performance have resulted in wide spread ac ....etc

industrial devices control using bluetooth module ppt

Abstract:

The main aim of this project is to control the electrical appliances in industry like machines, motors, etc using Bluetooth module.These Bluetooth modules are more reliable, secure and low power modules and these modules do not require line of sight also. We can use mobile Bluetooth by developing some applications or we can use normal USB blue tooth dongles by connecting to PC.Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavel ....etc
