Evolution of USB 2.0
Created as one of the first high speed capable connectivity options, USB 2.0 is popular for many machine vision camera applications. But the machine vision world is growing and so are their needs for high performance processing. Most developers and cameras manufactures turn to higher speed options despite their expense to gain better performance from vision systems. But USB 2.0 smart cameras change the price performance trade off and make high performance machine vision more affordable with USB2.0
In the beginning: USB
From its inception the USB2 interface for cameras has been an affordable and user friendly option. Initially designed to limit the number or ports used for PCs, USB expanded the capability of data transfer for the typical PC. After a while USB was not enough and was expanded by the USB 2.0 to enable real time transfer for high definition data, expanding the overall maximum speed of the connection. USB2 is widely available and easily integrated into existing systems. Almost all existing operating systems support USB2 technology and there is a variety of software and drivers available which are compatible with the technology.
For many reasons, USB2 is an excellent technology for the machine vision market but it does have some substantial drawbacks including bandwidth limitations, low frame rates and susceptibility to host platform activity which has limited it’s consideration as a viable technology for high performance machine vision applications.
Taking the Next step: USB2 with DSP
Smart USB 2.0 cameras are an innovative solution to this dilemma. By adding an embedded DSP (digital signal processor).USB 2.0 smart cameras provide high processing capabilities at the price of a USB camera system. DSPs increase the on camera memory and the processing capabilities of the USB, virtually eliminating the need for higher bandwidth capabilities. USB 2.0 smart cameras provide high levels of processing and data transfer for high performance applications at an affordable prices.

Malaria diagnosis is a huge challenge in developing countries where between 350-500 million people are infected with the illness each year. It is estimated that Malaria kills up to 2 million people each year, mainly children. Rapid detection and treatment make a huge impact on survival rates- while there is no cure for Malaria, early intervention with anti-malarial medications are highly effective and can often lead to a full recovery.
Video calling is a technological advancement that has made communication way easier for many people. In this way, you get to speak with a person from a hundred or so miles away through the Internet.
Mobile has made the switch from a voice- and messaging-centric technology to become a predominantly data channel. It's happened so fast that wireless networks are barely able to keep up, and growth will continue to compound for the foreseeable future. Wireless carriers & mobile operators are employing a variety of tools to help their networks handle data more efficiently and quickly, but none is as significant as the transition to fourth-generation technology, 4G Long Term Evolution (LTE).
