Latest Patents
Ichikawa's latest patents include a "Method and apparatus for stabilizing measured values for display." This invention processes data representing measured values that may show poor consistency. The method involves forming measured values into groups, calculating average and discreteness values, and presenting the average value as the most appropriate value for display when the discreteness value is below a reference value. If not, recalculations continue until the discreteness value meets the criteria.
Another notable patent is the "DC-to-DC Voltage converter." This device converts battery voltage to provide a power supply voltage that can be equal to the battery voltage multiplied by or divided by a non-integral factor, such as 2/3. The converter operates on the principle of capacitor charge switching, achieving high conversion efficiency at very low supply current levels, which are particularly useful in electronic timepieces.
