Icron USB Technology Enhances EEG Products from Nihon Kohden

Icron's Ranger 110 product is bolstering the capabilities and effectiveness of Nihon Kohden’s Neurofax EEG-1100A instruments designed to accurately measure brain activity.
Nihon Kohden is a manufacturer of neuro-diagnostic and monitoring instrumentation. The Neurofax EEG product design team set out to provide medical staff with complete flexibility in locating the machine and identified the need for an extended USB connection that can connect the Neurofax EEG to a computer in another room.
The company faced difficulties when it tried to use the computer in a different room from the power amplifier due to the 5-meters distance limitation presented by standard USB connections. Even though the company identified inexpensive USB extenders in the market, it proved difficult to find a product that worked flawlessly with the extremely precise equipment, said Bryan Kehoe, Nihon Kohden America Business Unit manager. The company also wanted a product that was easily customizable so that it could deliver the power requirements needed.
After testing a number of USB extenders, Nihon Kohden chose Icron’s Ranger 110 product for use with its EEG machines. The Ranger 110 was modified to increase the USB output power to meet the Neurofax’s power requirements. Icron also made a small change to grounding circuitry of Ranger 110, which ensured that there was no interference with the sensitive EEG machines.
Icron’s Ranger 110 was not only able to extend the maximum USB distance from five to 100 meters, but was also able to seamlessly power the EEG amplifiers.
Kehoe said working with Icron was a seamless and straightforward process. He noted that USB extension is an integral component of Nihon’s EEG systems.
Brian Donnelly, vice president of marketing and business development at Icron, said  Nihon's advanced EEGs are an excellent application for his company’s ExtremeUSB technology.
