With more and more people recording video and producing music, there are some new terms you may begin hearing. One of them is “Lavalier Microphone.”
Lavalier microphones are small microphones that can be clipped onto a person’s shirt to record their voice. They usually have their own power source in the form of a small battery pack with one AA battery. The small size of lavalier microphones make them ideal for sit-down interviews as they provide a close perspective sound and block out a lot of ambient sound such as traffic and wind. Many lavalier microphones are omni-directional, which means that the direction it is pointing is not significant. However, this also means that it can pick up other voices or sounds from nearby, which can distort the speaker’s voice.
As technology evolves, one this has remained constant – expandability on notebooks was primarily limited to the ‘PCMCIA (or PC Card) slot in the side. In 2004, the PCMCIA organization released a new technology – ExpressCardTM. This overview will provide an in-depth look at this new interface standard for notebooks and mobile systems.
Touted as the ‘New Standard for High-Performance, Lost-Cost I/O Expansion for Desktop and Mobile Systems,” ExpressCard Technology promises to deliver modular expansion at a lower cost and in a smaller form factor – with up to 2.5Gb/s bandwidth throughput. Users will be able to add memory, communications and security devices by simply inserting ExpressCard modules into their systems. The new standard supports ‘sealed box’ expandability in desktops and allows for thinner notebook design.
So you’re in the gym and see nearly everyone with some device strapped his or her arm. It looks like the remote control to your kid’s TV. The guy in the cube next to you at work always has his headphones on, his fingers drumming to a raucous beat that only he can hear. You take the kids to visit your mom and she even has one. What’s the world coming to? Are you the only person without one of those MP3 things? What’s it all about? Where did they come from? What are the differences between the MP3 players and how much do they cast? Well, you’ve come to the right place to get the knowledge you need and the player you want. 
Many years ago in a galaxy far away, well actually less than twenty years ago and in Munich, Germany, the Moving Picture Expert Group Layer III (MP3) was created. The folks at the Franunhofer Institute began researching this technology in the late 1980s. In 1989 they received a German patent for the MP3 and in 1996 the United States issued a patent for the MP3. Within a couple years the whole world began to see MP3 music, and players began popping up everywhere. 
What is Video Capture? 
Since its invention decades ago, there have been constant advances in television manufacturing. One thing has remained constant: the Cathode Ray Tube that projects images onto the television screen. Now the television industry is experiencing a paradigm shift that promises to
eliminate these traditional television sets by replacing them with flat panel technology. Plasma and LCD televisions and monitors provide breathtaking imagery and vibrant color. They also take up less space than ordinary televisions. The recent decline in price has catapulted the flat panel industry from designer chic to an emerging television standard.
