Latest Patents

One of Sakamoto's latest patents is an imaging element and imaging device designed for image plane phase difference detection. This innovation simplifies pixel formation in an imaging element configured to detect image plane phase difference. The imaging element features an on-chip lens, multiple photoelectric conversion portions, and several waveguides. The on-chip lens concentrates incident light on each pixel and is strategically placed to shift from the pixel's center based on the incident light's angle. The photoelectric conversion portions are arranged within the pixel to perform photoelectric conversion according to the incident light. The waveguides are designed to guide the concentrated incident light to each photoelectric conversion portion, with their shapes varying based on the on-chip lens's shift.

Another notable patent is a charge circuit that includes a current limiting circuit to restrict the current input from an input terminal. This circuit features a first transistor connected to a secondary battery, a charge control circuit to manage the supply of charge current, a second transistor that outputs a current proportional to the charge current, and a charge timer that generates clock pulses based on the current output. The charge control circuit is designed to stop the supply of charge current to the secondary battery once a predetermined number of clock pulses is reached.
