Title: Hiroshi Miyano: Innovator in Enciphering and Damping Technologies
Introduction
Hiroshi Miyano is a notable inventor based in Tokyo, Japan. He has made significant contributions to the fields of enciphering technologies and damping apparatuses. With a total of 2 patents, his work reflects a deep understanding of complex systems and innovative solutions.
Latest Patents
Miyano's latest patents include a hardware arrangement for enciphering bit blocks while renewing a key. This invention enciphers plaintext using multiple stages in tandem through several iterations. Each stage performs a complex key-dependent computation, utilizing a memory for key storage. The cipher function circuit transposes one block from a preceding stage using the key, while an exclusive-or circuit implements an exclusive-or operation with the output of the cipher function and another block. This unique arrangement allows for the key to be replaced with the output of the cipher function circuit.
Another significant patent is the active/passive damping apparatus. This damping apparatus is designed for large structures and operates both passively and actively. It includes a passive damping mechanism with added mass, springs, and dampeners, along with hydraulic cylinders connected to the added mass. An electro-hydraulic servo mechanism switches the hydraulic cylinders between passive and active operation, controlled by a unit that responds to the velocity and displacement of the added mass and the structure.
