Title: Innovations by Louis Ki Won Chang
Introduction
Louis Ki Won Chang is an accomplished inventor based in Carson City, NV (US). He holds three patents that showcase his expertise in surge protection technology. His innovative designs aim to enhance the safety and reliability of electrical systems.
Latest Patents
One of his latest patents is a surge protection device that fails as an open circuit. This apparatus is designed to open a surge path upon the failure of a surge protection element as a short. The device includes a switch controlled by a solenoid that changes the position of the switch if the surge protection element fails. In its first position, the switch allows the transmittal of a signal from a signal connection through the surge protection element to a ground connection. In the second position, the switch prevents this transmittal. A delay may be added between the switch position change after the surge protection element fails, and visual notifiers may indicate when the switch is in the second position.
Another significant patent is a high power band pass RF filter that incorporates a gas tube for surge suppression. This device features a housing that defines an interior chamber, which is divided into sections by walls. A circuit with filtering components is housed within this chamber, achieving strong attenuation of out-of-band signals. The ports on the housing connect to respective input and output nodes of the circuit and also to surge protection elements. An oil or other fluid is contained within the housing to cool the circuit components.
