Latest Patents
One of Pollard's latest patents is titled "Solar array augmented electrostatic discharge for spacecraft in geosynchronous earth orbit." This invention improves solar cell circuit layouts and cell structures that protect solar arrays located on spacecraft from electrostatic discharge. The use of an insulating material, such as RTV adhesive, serves as a barrier in the intercell gaps between solar cells. This modification alters the characteristics of sparking caused by electrostatic discharge, ensuring that while sparking occurs, it does not damage the solar cell materials. Additionally, unique wiring schemes limit the voltage between adjacent solar cells to 50 volts or less.
Another significant patent is the "Solar cell assembly," which features current limiting protection. This assembly includes a rectangular planar solar cell with four corner locations and a beveled edge. It incorporates parallel spaced longitudinally extending conductors on one surface and a metallic coating on the opposite surface. The design accommodates relative in-plane motion between a protective bypass diode and the solar cell, ensuring efficient operation and safety.
