Java has become a confusing world. Five years ago, there were few decisions to make once you started programming in Java—you used AWT for graphical user interfaces, sockets for network programming, and hacked together everything else you needed. Since then, though, the APIs available for the Java language have grown, and grown. . . and grown. Now you can dabble in Swing, servlets, Enterprise JavaBeans (EJB), JavaMail, and more. Additionally, there are now packages of APIs, like the Java 2 Micro Edition (J2ME) and Java 2 Enterprise Edition (J2EE). While these packages seem to be nicely wrapped bundles of useful APIs, they don t help the average developer figure out how to piece together the APIs contained in these packages. Though it s simple to find documentation on the individual APIs, getting the "big picture" is difficult, at best. One of the most interesting, but difficult, aspects of Java today is building Java enterprise applications using the J2EE package.

H.264/AVC is the current video standardization project of the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG). The main goals of this standardization effort are to develop a simple and straightforward video coding design, with enhanced compression performance, and to provide a 鈥渘etwork-friendly鈥?video representation which addresses 鈥渃onversational鈥?(video telephony) and 鈥渘on-conversational鈥?(storage, broadcast or streaming) applications.

In engineering, compensation is planning for side effects or other unintended issues in a design. The design of an invention can itself also be to compensate for some other existing issue or exception. One example is in a voltage-controlled crystal oscillator (VCXO), which is normally affected not only by voltage, but to a lesser extent by temperature. A temperature-compensated version (a TCVCXO) is designed so that heat buildup within the enclosure of a transmitter or other such device will not alter the piezoelectric effect, thereby causing frequency drift. Another example is motion compensation on digital cameras and video cameras, which keep a picture steady and not blurry.

The i-mode service by NTT DoCoMo is a mobile phone service in Japan that provides its customers with both voice and comprehensive data services. With an i-mode phone, users can exchange i-mode e-mail and obtain information from i-mode menu sites and i-mode compatible Internet sites. The i-mode phone contains a browser that displays i-mode compatible HTML web pages. Beginning with the 505i phones, you can view Macromedia Flash Lite movies from the i-mode browser. You can also use the phones’ My Picture and Standby Screen applications to view Flash Lite movies. Although a number of manufacturers produce 505i phones, all of them support the same Flash Lite functionality.

一种以硅单晶为基本材料的P1N1P2N2四层三端器件，创制于1957年，由于它特性类似 双向可控硅 于真空闸流管，所以国际上通称为硅晶体闸流管，简称可控硅T。又由于可控硅最初应用于可控整流方面所以又称为硅可控整流元件，简称为可控硅SCR。 在性能上，可控硅不仅具有单向导电性，而且还具有比硅整流元件（俗称“死硅 ”）更为可贵的可控性。它只有导通和关断两种状态。 可控硅能以毫安级电流控制大功率的机电设备，如果超过此频率，因元件开关损耗显著增加，允许通过的平均电流相降低，此时，标称电流应降级使用。 可控硅的优点很多，例如：以小功率控制大功率，功率放大倍数高达几十万倍；反应极快，在微秒级内开通、关断；无触点运行，无火花、无噪音；效率高，成本低等等。 可控硅的弱点：静态及动态的过载能力较差；容易受干扰而误导通。

如果在调谐器或电视机附近使用本机或任何其他使用微处理器的电子设备，则可能会产生图像的噪声或干扰。如果发生这种情况，请采取以下步骤将本机安装在尽可能远离调谐器或T的地方。远离调谐器或T，远离本机的电源线和输入/输出连接电缆。尤其在使用室内天线或300欧姆馈线。我们建议使用室外天线和75 Q / ohm同轴电缆Noise or disturbance of the picture may be generated if this unit or any other electronic equipment using microprocessors is used near a tuner or TV If this happens, take the following stepsInstall this unit as far away as possible from the tuner or T Run the antenna wires from the tuner or T away from this unit ' s power supply cord and input/output connection cables. Noise or disturbance tends to occur particularly when using indoor antennas or300 ohm feeder wires. We recommend using outdoor antennas and 75 Q/ohm coaxial cables
