Title: Kirk Su: Innovator in Power Over Ethernet Technology
Introduction
Kirk Su is a prominent inventor based in Santa Barbara, CA (US). He has made significant contributions to the field of power over Ethernet (PoE) technology, holding a total of 8 patents. His work has advanced the way data and power are transmitted over Ethernet cables, enhancing the efficiency and functionality of various devices.
Latest Patents
One of Kirk Su's latest patents is a detection and classification scheme for power over Ethernet systems. In this innovative method, a power sourcing equipment (PSE) provides data and operating voltage over Ethernet wires to a powered device (PD). Before supplying the full PoE voltage, the PSE generates a low current signal that is received by the PD. A circuit within the PD, connected across its input terminals, exhibits a characteristic analog response to the PSE signal, which corresponds to the PD's PoE requirements. This includes determining whether the PD is a Type 1 or Type 2 device. The circuit may consist of various components such as a capacitor, zener diode, or resistor. The PSE can generate a fixed current, fixed voltage, or a time-varying signal. Upon sensing the magnitude of the analog signal response at a specific time, the PSE associates this response with the PD's PoE requirements and subsequently applies the full PoE voltage accordingly.
