Introduction

Julius Lange is a notable inventor based in Cupertino, California, recognized for his contributions to the field of analog signal processing. With a total of eight patents to his name, Lange has developed innovative technologies that enhance privacy and signal quality in high bandwidth transmissions.

Latest Patents

One of Lange's latest patents is the "Analog Privacy Scrambler and Scrambling Method." This invention provides a system and method for maintaining privacy during the transmission of high bandwidth analog signals. The preferred system breaks an input signal into bands and employs Walsh codes to overlay multiple signals using phase modulators, effectively scrambling the input signal. The scrambled signal is transmitted, and upon reception, the phase modulation is removed. An inverse Walsh transform is then utilized to recover the original bands, which are combined to restore the original signal. This method ensures synchronization and phase coherency throughout the process.

Another significant patent is the "Passband Transversal Equalizer." This invention features a novel partitioning of circuits that improves dynamic range and minimizes unwanted signal interactions. The passband transversal equalizer employs an innovative interconnection matrix and can be implemented using GaAs monolithic microwave integrated circuit (MMIC) devices for enhanced performance. It includes a divider that splits an input signal into several predetermined signal paths, with coaxial delay lines providing relative delays. Active dividers with push-pull outputs are coupled to the delay lines, and an interconnection matrix connects the outputs to complex weighting and combiner circuits. The signals are then delayed again and combined to produce an equalized output.
