Title: The Innovations of Kan-Chiu Seto
Introduction
Kan-Chiu Seto is a notable inventor based in Saratoga, CA (US), recognized for his contributions to the field of power distribution in Ethernet technology. With a total of 3 patents, Seto has made significant advancements that enhance the efficiency and functionality of powered devices.
Latest Patents
One of Seto's latest patents is titled "Method and apparatus for current sharing ethernet power across four conductor pairs using a midspan device." This invention discloses methods and apparatus for balancing power across all conductors of an Ethernet connection. The balancing circuitry allows an Ethernet midspan device to receive power from an Ethernet Power Sourcing Equipment (PSE) on the signal pairs of an Ethernet connection. The circuitry is designed to sense the level of the received power and generate a second power source that is substantially equal to the received power level. This innovation enables the received power to be provided to an Ethernet Powered Device (PD) over the signal pairs, while the generated power is supplied to the PD over the unused pairs of the Ethernet connection.
Another significant patent is "Method and apparatus distributing power to a load in a powered device." This invention describes a powered device, such as an IP telephone, that includes power converter electronics. These electronics allow the powered device to connect to multiple power sources and receive a relatively large amount of power, such as 15 W or greater, from any single power source or from a combination of power sources. The converter circuitry can provide power to the load from either the first power source or the second power source, or from both sources simultaneously.
