This invention describes a device that tracks the sun to collect and reflect its rays. It uses a mirror, supported to move on two axes, with an accelerometer mounted on it to sense its motion. A control system then uses this motion data, along with sun position information, to drive motors and keep the mirror optimally pointed at the sun, specifically for concentrating solar radiation.
Why it matters: Filed before the widespread availability of low-cost, high-precision MEMS accelerometers and microcontrollers. These components, now common in consumer electronics, make implementing the tracking and control system significantly cheaper and more accessible.
