Title: Innovations by Hong Yi Wee

Introduction

Hong Yi Wee is a notable inventor based in Singapore, recognized for his contributions to power-over-Ethernet (PoE) technology. He holds a total of four patents, showcasing his expertise in developing innovative solutions for efficient power management in electronic devices.

Latest Patents

One of his latest patents is titled "Adaptive backoff time in power-over-ethernet detection cycles." This invention provides a power sourcing equipment controller that delivers power to a powered device using PoE. The controller includes a voltage-output logic block that outputs a sequence of voltage signals, which consist of a detection signal and a classification signal. Additionally, it features a current-measurement logic block that measures the current provided in response to these voltage signals. A backoff-time-determination logic block determines a backoff time when the current exceeds a predetermined threshold, ensuring efficient power management. The timing logic block then delays the output of the next sequence of voltage signals based on this backoff time, facilitating the powering up of devices compliant with different PoE standards.

Another significant patent by Hong Yi Wee is "Response mechanisms for power-interruption events in PoE systems." This patent outlines systems and methods that enable efficient reallocation of PoE when a power supply unit (PSU) for a power sourcing equipment (PSE) fails. The PSE initially receives power from multiple PSUs and provides PoE to several powered devices (PDs). When one PSU becomes unavailable, the PSE stops providing PoE to one PD while continuing to supply power to another. The PSE communicates with the second PD to request a reduction in power allocation, allowing for a more efficient distribution of available power.
