See.Sense. uses a suite of advanced sensors to monitor orientation, acceleration, light levels, voltages and temperatures. Its primary sensor is an accelerometer more commonly found in mobile phones. This allows it to measure acceleration and orientation up to 800 times a second. It also measures the capacitance of a reverse biased LED to determine light levels.

An onboard microcontroller operates at 8 million instructions per second to analyse the data and determine input data values, such as cadence (pedalling rate), illumination levels, road surface conditions, travelling uphill or downhill, acceleration or braking, cornering lean, yaw (rotation) and so on.

This is then fed through a decision matrix to identify scenario events such as traversing a junction or roundabout, being approached by car headlights, filtering in traffic, obstacle avoidance, lane positioning, entering a dimly lit area (such as a road tunnel or underpass), starting off and so on. A flashing and brightness pattern is then calculated and sent to a very efficient constant current driver which powers the top grade LED. Voltage and temperature measurement enable the device to operate efficiently in all situations. This use of technology is covered in a fourteen page patent application which is currently pending.
