Zhang's latest patents include a high accuracy and high dynamic range MEMS inertial measurement unit with automatic dynamic range control. This invention relates to a MEMS IMU that utilizes automatic gain control to optimize the dynamic measurement range. By adjusting the gain of a signal amplifier before the analog to digital converter (ADC), the system maximizes the ADC range. In one embodiment, multiple MEMS inertial sensor sets are integrated into the IMU, allowing for high accuracy with low dynamic range and higher dynamic range with less resolution. A digital processor determines which sensor set to use based on system dynamics.

Another notable patent is for inertial sensing with a spatially distributed sensor array and two-dimensional data processing. This design aims to reduce measurement errors and enhance signal detection accuracy. By combining measurements from sensors with non-orthogonal sensing axes, correlated errors due to environmental changes are minimized. The use of a two-dimensional signal processing method further refines the output data, increasing the signal-to-noise ratio.
