Wong: How does the SideKick work?
Neel: The SideKick uses a biosensor to convert glucose in blood to current. The current is then measured by a custom "BG system on chip" ASIC designed by HDI & Texas Instruments. The current is then mapped to a standardized glucose reference method to produce a calibrated result. In order to match the test strip specific characteristics with the meter, a code is assigned during manufacturing that conveys the test strip lot calibration information to the meter. This eliminates the need for the user to code the meter…and any possible coding errors.

Wong: What is the accuracy of the SideKick?
Neel: The accuracy of SideKick is equivalent to non-disposable full-featured monitors.

Wong: How does the SideKick compare with other glucose testing systems?
Neel: The SideKick is the smallest glucose monitor on the market. It provides quick test results (5 seconds), uses a low blood volume (1ul), stores results in memory, and requires no coding steps.

Wong: What is the basic architecture of the SideKick? (processor, sensors, etc.)
Neel: The SideKick employs a custom ASIC with a MSP430 microcontroller, RAM & flash Memory, LCD controller, and biosensor test media interface components (multi-input channel Sigma Delta A/D, D/A, temperature sensor).

Wong: Are there any special technologies employed by the SideKick?
Neel: Special technology was required in several areas to meet the system goals. We needed low power electronics to use a small battery, high accuracy, low noise analog performance for the test media interface, and a very high level of integration to meet size requirements.

Wong: Why did you choose the MSP430?
Neel: The MPS 430 Microcontroller family is designed for use in high-integration applications that require very low power. Texas Instruments had the skill to integrate high quality analog and digital circuits on one substrate to achieve the desired performance and integration at a low cost.
