Latest Patents

Takeshi Watari's latest patents include a signal readout circuit, a signal readout device, and a signal readout method for photodetection elements. The signal readout circuit is designed to read signals from a photodetection element that consists of multiple photodetection pixels. Each pixel generates a detection signal based on light incidence. The circuit features N light incidence detection units, which input detection signals from each pixel and output a signal indicating light incidence. Additionally, a total value detection unit calculates the total value of the output signals from these units. Each light incidence detection unit is configured to output signals with different weights corresponding to each photodetection pixel, ensuring that total values vary for each pixel and all possible combinations.

Another significant patent is related to a laser processing apparatus. This apparatus includes a light source that emits laser light and a waveform control unit that manages the pulse waveform of the laser light directed at a workpiece. The controlled pulse waveform consists of a main pulse and a foot pulse that precedes it. The peak intensity of the foot pulse is lower than that of the main pulse, and the timing of the main pulse is strategically positioned during the retention time of plasma generated by the foot pulse's incidence on the workpiece.
