Title: Mitsunori Maruyama: Innovator in Passenger Protection Technology
Introduction
Mitsunori Maruyama is a notable inventor based in Okazaki, Japan. He has made significant contributions to the field of passenger protection technology, holding a total of 6 patents. His innovative designs focus on enhancing the safety of passengers during collisions.
Latest Patents
One of his latest patents is a starting device for a passenger protecting device. This device integrates the output signal of an acceleration sensor through a band-pass integrating means while restricting the upper limit of the output signal within a specified frequency range. It features a comparing means that outputs a starting signal when the integrated value exceeds a predetermined threshold. This ensures that the device activates appropriately during a collision while avoiding false activations from vibrations caused by low-speed impacts.
Another significant patent is a starting apparatus for a passenger protecting apparatus. This apparatus includes a collision deciding unit, a control unit, and a trigger. The collision deciding unit determines whether a collision has occurred based on the output from an acceleration sensor. The control unit generates a starting signal by comparing outputs from decelerating and accelerating direction integrating units. The trigger then outputs the starting signal based on the collision decision and control unit output.
