Title: Innovations of Joachim Grosse

Introduction

Joachim Grosse is a notable inventor based in Breisach-Gundlingen, Germany. He has made significant contributions to the field of electronics, particularly in the development of CMOS circuits and keyboard switch matrices. With a total of 3 patents to his name, Grosse continues to push the boundaries of innovation in his field.

Latest Patents

One of Grosse's latest patents is a CMOS circuit designed for converting a ternary signal into two binary signals. This innovative circuit utilizes two CMOS inverters that are dimensioned extremely unsymmetrically concerning their W/L ratio and are connected in parallel at their inputs. By adding a NAND or NOR gate, the circuit can function as an integrated circuit option releasing stage without requiring an additional terminal for the option signal. The middle value of the ternary signal serves as the option signal, while the lower and upper values represent the binary signals.

Another significant patent involves a circuit arrangement for an input keyboard. This design features a keyboard switch matrix with multiple column and row wires, along with switches that have only two poles and no interconnecting diodes. The arrangement allows for selective connection of one column to one row. Each column and row wire is associated with a flip-flop, which stores the geometric position of the actuated keyboard switch. The outputs of the flip-flops provide code signals corresponding to the switch's position.
