Latest Patents

One of Lin Able Chu's latest patents focuses on an innovative IP telephone system. This system features a constant impedance filter that can be continuously attached to the physical layer of a computer chip within the IP telephone. The filter is strategically located outside the physical layer and connects to a relay on the physical layer. The relay utilizes native FET devices, which are normally conductive without a supply voltage. This design allows the relay to operate during the discovery mode of IP telephone operation, even when no power is applied to the substrate. Rectifier circuits are employed to rectify incoming signals during this mode, enhancing the relay's conductivity for faster detection of the IP telephone. During normal operation, voltage is applied to the physical layer, and the relay is opened by grounding the native devices. Additionally, any signal from the constant impedance filter is terminated in a switchable termination resistor located on the physical layer.
