Latest Patents
Dohi's latest patents include a touch switch and a control panel. The touch switch patent introduces a technique that reduces erroneous judgment caused by noise effects during PWM control. This innovation is particularly useful for brightness adjustment of light-emitting diodes (LEDs) located near an electrode. The system employs a CPU to perform brightness adjustments through PWM control, while a detecting circuit outputs values based on the electrostatic capacitance of the electrode. The CPU determines a touch operation when the difference between the detected value and a stored reference value meets a specified threshold.
The control panel patent similarly addresses noise-related issues in PWM control. It features LEDs that illuminate operating portions and serve as indicators. The circuitry adjusts the brightness of the LEDs through PWM control, with a detecting circuit that outputs values based on electrostatic capacitance. The CPU senses touch operations by comparing detected values to a reference value, ensuring accurate functionality.
