Title: Joseph Harold Havens: Innovator in Simulation Technology and Low-Noise Mixing

Introduction

Joseph Harold Havens is a notable inventor based in Musashino, Japan. He holds a total of 5 patents that showcase his contributions to the fields of simulation technology and low-noise mixing. His innovative work has significantly impacted various industries, particularly in enhancing the efficiency of simulation tasks and improving audio signal processing.

Latest Patents

Havens' latest patents include a "Device and method for parallel simulation task generation and distribution." This invention provides a simulation task generator that receives a range of parameters desired for a particular parallel simulation. The generator determines specific combinations of parameters corresponding to each simulation task and assigns estimated performance ratings for each task. It retrieves information from a database indicating the availability of accessible processors and their corresponding ratings. The generator matches simulation tasks to available processors to achieve optimum performance. Additionally, some processors may act as secondary distributors, generating and distributing tasks more conveniently.

Another significant patent is the "Low-noise mixer." This invention discloses a four-quadrant mixer with a low noise factor. It suppresses the indeterminate common-mode voltage that may accompany the modulating signal and replaces it with a common-mode quiescent voltage. This design establishes a predetermined quiescent biasing current through the mixer transistors' common biasing resistors. The mixer can be driven in common-mode by the modulating signal and differentially by the local oscillator signal. This innovation allows for larger emitter biasing resistors to be used while maintaining the same emitter current, or conversely, larger emitter currents can be specified to achieve a desired signal-to-noise ratio.
