Latest Patents
Among his latest patents is the "Network interface card (NIC) with phase lock rise time control generating circuit." This invention pertains to a Network Interface Card (NIC) designed for connecting data terminal equipment to a communications network. The NIC features a Phase Lock Loop (PLL) with a master delay structure that is operatively coupled to at least one delay line structure. The PLL generates control pulses at precise delayed intervals, which are utilized to gate data through the delay line structure.
Another significant patent is the "Method and apparatus for adaptive equalization of high speed data communications." This invention describes a method and apparatus for adaptively removing interference from a signal. The received signal is amplified linearly along a first signal path to provide a first signal and amplified nonlinearly along a second signal path to provide a second signal. Both signals propagate through their respective paths simultaneously. The amplified signals are mixed in proportion according to determined weights to produce an output signal with interference removed. The output signal is then filtered to create two filtered signals, which are compared to generate an error signal that helps in determining the weights.
