Title: Innovations of James K. Krider
Introduction
James K. Krider is an accomplished inventor based in North Vernon, Indiana. He is known for his innovative contributions to the field of noise cancellation technology, particularly in automotive applications. His work has led to the development of a unique electronic muffler assembly that significantly reduces engine exhaust noise.
Latest Patents
One of Krider's notable patents is the "Electronic muffler assembly with exhaust bypass." This invention utilizes an active noise cancellation system to quiet engine exhaust noise. The combustion products from an engine pass through a conduit to an acoustical mixing chamber located in the tailpipe. A microphone senses noise in the vicinity of the tailpipe and provides a signal to a control unit. The control unit generates a controlling signal sent to one or more speakers mounted in a housing that is coupled to the tailpipe. The sound produced by the speakers enters the mixing chamber to mix with and cancel sound from the combustion product exiting the conduit. Some embodiments include a muffler housing forming an interior chamber divided into two sub-chambers. Other variations include a muffler with an outer housing enclosing an inner housing. The design allows for flexibility in the number of speakers mounted in each chamber and their orientation to direct sound waves toward the exit of the housing and into the mixing region located in the tailpipe. Krider holds 1 patent for this innovative technology.
