Latest Patents
One of Kawai's latest patents is a "Camera utilizing a satellite positioning system." This innovative camera is designed to receive electric waves that include position information from satellites of the Global Positioning System. It records the photographing position alongside the captured image, allowing for an arbitrary change in the camera's photographing attitude based on the image being photographed. The camera features an enabling device that facilitates the reception of electric waves through an antenna, regardless of its photographing attitude.
Another significant patent is the "Process for detecting a focal point in an optical head." This method employs an optical system that includes a laser diode light source, a beam-splitter prism, an objective lens, a photodetector, and a mechanism for moving the objective lens perpendicular to the recording surface. The method involves placing the prism to ensure the incident angle of the light flux through the objective lens is less than the emergent angle from the prism to the photodetector. It detects light intensity and drives the objective lens based on an electrical signal.
