Latest Patents

One of Xunwei Yu's latest patents is focused on systems for controlling the charging of electrical devices. This innovative charger prevents the charging of a wearable device battery when sweat or other conductive contaminants are present. The charger initially provides a low voltage to detect engagement with the wearable device. When engaged, a measured current value exceeds a threshold minimum. If contaminants are present, the additional conductive pathway will cause the measured value to exceed a threshold maximum, thus preventing battery charging. Conversely, if no contaminants are detected, the measured value remains between the threshold minimum and maximum, allowing for higher voltage to charge the battery.

Another notable patent is the synchronous voltage signature data collection apparatus. This apparatus is designed to concurrently measure multiple input voltages at a high sampling data rate, such as at least two mega-samples per second. It includes several voltage data acquisition components that sample different input voltages and produce respective voltage data samples. Each component is directly coupled to a field programmable gate array, which receives, packetizes, and provides the voltage data samples to a system on chip.
