ReThink Medical was founded with a goal of enabling the technologies to make healthcare proactive. We develop non-invasive wireless (Bluetooth, WiFi, or Cellular) ambulatory (battery-powered) physiologic monitoring devices with a wide range of applications.
We want to empower researchers with new paradigms of data collection. We want to help other companies fast-track their concepts with proof-of-concept hardware to help innovate new solutions. We also aim to provide our own solutions for a wide range of health problems, such as the management of heart-disease and chronic stress.
The EEG device will collect a lot of data, about 45 Megabytes/hour. Unfortunately, the MSP430 series of microcontrollers only supports full-speed USP (12Mbps), along with the slow clock (12.5MHz max SPI bus speed) means that it will take 2.8 minutes to transfer one hour of recorded data to the PC. That’s too slow.
I recently found a new IC my Maxim, the MAX1450x. The IC is designed to fit between the USB port and the microcontroller and between the SD card and the microcontroller. When switched on, it will bypass the microcontroller and allow for a hi-speed USB connection with an MSC profile to allow much faster data transfer between the PC and the SD card.
The IC appears fairly new with a long backlog, and it isn’t cheap (~$11) but I think it will make the user experience much better. I just sent off an order for the evaluation kit to check it out.
I’m finally getting around to makeing this site do something interesting.
