Title: The Innovations of Tarmo Tammaru
Introduction
Tarmo Tammaru is a notable inventor based in Middletown, NJ, who has made significant contributions to the field of data transmission and error detection. With a total of two patents to his name, Tammaru's work showcases his expertise in developing advanced technological solutions.
Latest Patents
Tammaru's latest patents include a data scrambler and a one-bit-out-of-N-bit checking circuit. The data scrambler patent describes a method for randomizing binary digital data signal patterns. This is achieved by constructing a key signal from a summation of selected stored digits of the data pattern. The resulting scrambled line signal is free of concentrated signal energy at particular frequencies, ensuring reliable recovery of synchronization information. The descrambling process is accomplished by precisely reversing the scrambling operation, making the system self-synchronizing.
The one-bit-out-of-N-bit checking circuit patent involves a series of detector levels that accommodate multiple input signal lines. Each detector level is designed to detect excitation signals and generate error signals accordingly. The k-th detector level produces an output signal in response to the presence of an excitation signal on only one of the input signal lines, enhancing the reliability of data transmission.
