Latest Patents

One of Toshiaki Ito's latest patents is focused on capacitive touch sensor device configuration systems and methods. This invention includes capacitive touch sensors and methods for configuring them. The embodiment features an analog-to-digital converter (ADC) that receives an analog voltage signal from an electrode. The ADC samples this signal to produce a plurality of digital values. The controller then performs a first charging process by supplying the electrode with a first charging current for a specified interval. Based on the digital values, the controller determines if the first electrode voltage value meets a certain criterion. If it does not, the controller initiates a configuration process to adjust the charging current and interval, ensuring the second electrode voltage value meets the required criteria.

Another notable patent by Ito is an address decoder and method for setting an address. This invention includes a level comparator, an edge detector, and an output decoder. The level comparator compares an SDA signal with an address selection signal and outputs a comparison result. The edge detector detects an edge of the address selection signal, while the output decoder sets the address corresponding to the connected destination of the ADDR terminal. This innovation is crucial for determining the address of a slave module connected to the address decoder.
