Latest Patents
One of her latest patents is titled "Low noise method and apparatus for driving electroluminescent panels." This invention provides a reduction in EL panel noise and includes voltage compensation as the EL panel ages. The design utilizes a high voltage power supply applied through a circuit with an optimized time-constant, producing a waveform that minimizes EL panel vibration. This method ensures that the aging of the EL panel maintains the time constant in the proper range, thus preserving noise reduction and compensating for brightness reduction over time.
Another notable patent is the "Method for improving the efficiency of discharging capacitive loads in H-bridge electrical switching devices." This method enhances the efficiency of devices that drive capacitive loads, such as electroluminescent lamps and liquid crystal devices. By implementing discharge steps that first bring the capacitive load to zero volts before recharging, the method reduces the energy required from the DC power supply, resulting in a more efficient switching network.
