Latest Patents
Chang's latest patents focus on the improved powering down of PoE interfaces. One of his notable inventions involves detecting faults that interrupt the flow of power from power supply units (PSUs) to PoE interfaces. The technology determines a total operational power value based on the operational power of each PSU and assesses whether the threshold power value for each PoE interface exceeds the total available power value. If it does, the PoE interface is powered down to prevent damage and ensure efficient operation. Another patent further enhances this process by setting power fault values for each PSU and determining whether the total power fault value meets the power threshold for each PoE interface, leading to a more reliable power management system.
