Abstract: A method and apparatus for providing efficient and accurate electronic data transmission of information on a data bus in the presence of noise. Data signals are received on a plurality of input lines by a spacial derivative encoder. The spacial derivative encoder encodes the signals and transmits them to a receiver having a spacial derivative decoder. The spacial derivative decoder then decodes the signals. Minimal overhead is required as for n input lines only n+1 lines are needed to transmit each of the encoded signals.

Abstract: A system and method for encoding N signals onto an N+1 conductor signal line. First, the electrical characteristics of the signal line are determined by calculating an inductance matrix for each conductor, calculating electrostatic inductance for each conductor and calculating an eigen-mode encoding matrix. The N signals are then encoded into signals enc(0) through enc(n), wherein the step of encoding comprises the step of encoding each of the N signals as a function of the eigen-mode encoding matrix.

Abstract: A completely shielded metallized connector block for use in multiple circuit modules of an electronic device. Electrical communication between the circuit boards is effected by an array of metallic pins which run through the blocks. The metallization on the nonconductive blocks can be held at ground or at a constant potential to increase the shielding between pins as well as maintaining voltage and ground planes at constant levels throughout the modules. The metallization is insulated from the pins and circuit boards by nonconductive bushings inserted in holes in the blocks. In one embodiment, the metallization consists of copper and solder plating and the blocks are constructed of liquid crystal polymer.
