Title: Innovations by Joseph W. Balch

Introduction

Joseph W. Balch is a notable inventor based in Livermore, CA, with a remarkable portfolio of 13 patents. His work primarily focuses on advanced bonding processes and DNA manipulation techniques, contributing significantly to both materials science and biomedical fields.

Latest Patents

One of Balch's latest patents is for "Plates for vacuum thermal fusion." This innovative process effectively bonds substrates of arbitrary size or shape by incorporating vacuum pull-down techniques. The method ensures uniform surface contact during the bonding process, which is crucial for materials like glass, plastic, or alloys. By applying an active vacuum source, Balch's technique evacuates interstices between the substrates while providing a positive force to hold them in contact. This allows for an increase in temperature to reach the softening point, ensuring that small void areas are filled and come into contact with the opposing substrate. The process is particularly effective when at least one of the substrates contains channels or grooves for vacuum application during the thermal bonding cycle.

Another significant patent is the "Microfluidic DNA sample preparation method and device." This invention addresses the challenges of DNA manipulation in solution, which is essential for genetic analyses. Balch's method automates the steps involved in preparing DNA samples, significantly reducing time and labor. By utilizing dielectrophoresis (DEP), his technique allows for the manipulation and separation of DNA in an efficient manner. This innovation not only streamlines the process but also enables the miniaturization of DNA analysis instruments.
