模拟电子 降低EMI和保持高效率D类放大器在便携式产品中的应用
Abstract: Class D amplifiers are typically very efficient, making them ideal candidates for portable applications that require longbattery life and low thermal dissipation. However, electromagnetic interference (EMI) is an issue that commonly accompanies theClass D switching topology. Active-emiss ...
电源技术 LT1300和LT1301在功率DCDC转换器中的应用
 
The design of battery-powered equipment can often bequite challenging. Since few ICs can operate directly fromthe end-of-life voltage from a 2-cell battery (about 1.8V),most systems require a DC/DCconverter. The systemdesigner often has a limited area in which to place the DC/DC converter ...
书籍 LTE-Advanced+DRX+Mechanism
Today, our everyday life is almost impossible to detach
from the influence of wireless mobile communication
technologies. This global trend is growing exponentially, and
the mobile-only data traffic is expected to exceed stationary
data traffic. However, for further development of mobile
communicati ...
电源技术 笔记本电脑的功率调节系统
 
Notebook and palmtop systems need a multiplicity ofregulated voltages developed from a single battery. Smallsize, light weight, and high efficiency are mandatory forcompetitive solutions in this area. Small increases inefficiency extend battery life, making the final productmuch more usab ...

This article describes how to consume Web services in Java 1.5.0 using the new JAX-WS 2.0 API (JSR 228).
Developers around the world, including me, have always complained about the hard ways to work in Java to consume even a Web service as simple as adding two numbers.
However, with JAX-WS 2.0 A ...
