Latest Patents

One of his notable patents is a method and apparatus to protect solar cells from electrostatic discharge damage. This invention outlines various methods to prevent cellular degradation caused by electrostatic discharge pulses. In one embodiment, a diode is utilized to bypass current generated from an electrostatic discharge, ensuring that the pulse current does not reverse bias the solar cell. Advanced diodes, capacitors, and multiple diodes on various bypass current paths may be employed. Another embodiment increases the transient impedance of the current path that reverse biases the solar cell by using inductors along the reversing current path. Additionally, the pulse current rise rate can be reduced by extending the harness length of cell contacts. Furthermore, solar cells arranged in a serpentine pattern can be protected from electrostatic discharge damage by coupling bypass current paths to the open ends of the serpentine, with inductors placed in series with the cells.

Another significant patent is a control system for electrostatic discharge mitigation. This control circuit includes a heater that is thermally coupled to an electric component. A sensor is employed to detect a sensed condition, while a controller is connected to both the heater and the sensor. The controller activates the heater in response to the sensed condition, which may involve monitoring the electron flux level near the component or the surface potential of the component itself.
