Title: The Innovative Contributions of Keith R Johnson
Introduction
Keith R Johnson is a notable inventor based in Orland Park, IL (US). He has made significant contributions to the field of electronic components, particularly in the development of resolver and encoder assemblies. With a total of 4 patents to his name, Johnson's work showcases his commitment to innovation and technology.
Latest Patents
Johnson's latest patents include a digital resolver/encoder assembly that is designed to be impervious to moisture. This invention involves a method of forming a compact resolver/encoder assembly through several steps. First, a number of electronic components of the resolver/encoder are mounted on a flexible printed circuit board. The circuit board is then folded into a generally cylindrical envelope and placed in a cylindrical container with a closed bottom end and an upper open end. The folded circuit board tends to unfold against the inner surface of the cylindrical wall of the container. A form made of stiff but flexible paperboard is inserted within the cylindrical envelope, which tends to unfold to take on a tear drop cross section. Next, a heat insulating potting compound is inserted into the annular space in the container between the form and the cylindrical wall, allowing the potting compound to set around the circuit board. Finally, a stator and rotor assembly are mounted within the cylindrical space and fixed to the container.
Another of his notable inventions is the compact digital resolver/encoder assembly, which comprises a resolver and a flexible printed circuit board with electronic components for decoding the resolver. This assembly is designed to be housed in a cylindrical container, ensuring that the circuit board is insulated from the container by an electrical insulating potting compound. A voltage regulator is also mounted to the inside wall of the container, enhancing the functionality of the assembly.
