Latest Patents

Hoshi's latest patents include a capacitive touch sensor device configuration system and methods. This invention encompasses capacitive touch sensors and methods for configuring them. The system features an analog-to-digital converter (ADC) that receives an analog voltage signal from an electrode. The ADC samples this signal to produce a series of digital values. The controller then performs a charging process to determine if the electrode voltage meets specific criteria. If it does not, the controller adjusts the charging current and interval to achieve the desired voltage.

Another notable patent is the light-emitting element drive apparatus. This invention allows for high-speed and high-accuracy light-emission control of a light-emitting element. It includes a monitoring photodiode that generates a current corresponding to the optical output of a laser diode. The current is converted to a monitor voltage, which is then smoothed to produce an average value. This setup ensures that the optical power setup voltage is generated in synchronization with the average value, enhancing the overall performance of the light-emitting element.
