Latest Patents

One of Xiaofu's latest patents is focused on respiration monitoring based on noisy channel state information (CSI) data. This technology involves receiving CSI data that represents the channel properties of a wireless connection between two devices. The method generates a set of CSI samples, removes outliers, and determines Fast Fourier Transform (FFT) data to identify a breathing spectrum. Ultimately, it calculates the respiratory rate of a user in a specific geographical region.

Another notable patent involves proximity detection using device-to-device communication links. This technique allows for high-precision presence detection by establishing peer-to-peer communication links between user devices in the same physical environment. The user device monitors fluctuations in channel properties to determine if a user is in close proximity, enhancing the accuracy of presence detection.
