Title: Cluster storage apparatus for post processing error correction of a character recognition machine
IPC: G06V30/262
Filed: 1975-09-29
Abstract: A cluster storage apparatus is disclosed for outputting groups of valid alpha words as potential candidates for the correct form of an alpha word misrecognized by a character recognition machine. Groups of alpha words are arranged in the cluster storage apparatus such that adjacent locations contain alpha words having similar character recognition misread propensities. Alpha words which have been determined to be misrecognized, are input to the cluster storage apparatus. Numerical values assigned to the characters of which the input word is composed, are used to calculate the address of that group of valid alpha words having similar character recognition misread propensities. The cluster storage apparatus then outputs the accessed groups of alpha words for subsequent processing. The organization of the cluster storage apparatus minimizes the difference in address between alpha words with similar character recognition misread propensities by assigning high numeric values to highly reliable characters, as determined by measuring the character transfer function of the character recognition machine.

Title: Electronic injection carburetor
IPC: F02D41/18
Filed: 1978-11-07
Abstract: An electronic injection carburetor is disclosed. Fuel under pressure is quantized for primary metering by an electronic fuel injector and input to a metered fuel chamber. The quantization occurs by controlling the duration of the opening time of the injector by an electronic control unit responsive to speed and manifold absolute pressure information. Secondary metering is provided as a function of the mass air flow through the throat of the carburetor by an actuator assembly controlling fuel input to the carburetor from the metered chamber. The actuator provides the secondary metering by changing the bias pressure on a flexible diaphragm producing a closure force on a needle valve that varies the flow of fuel from the metered chamber to an atomizing discharge nozzle in the throat of the carburetor.
