Latest Patents

Onishi's latest patents focus on improvements to control devices and distributed control systems. One pivotal patent addresses the challenges faced when there is a discrepancy in communication delays among control devices. In conventional systems, control devices update their data areas in response to control packets, which can cause inconsistencies due to varying communication delays or jitter. To overcome this, Onishi's invention allocates time slots on the network based on calculations from a specialized unit. A cyclic memory synchronization update unit then ensures that the timing of data reflection in both input/output systems and cyclic memory is perfectly synchronized.

His second patent elaborates on a control system that consists of multiple control nodes and I/O nodes. In this innovative setup, control nodes execute programs on one operating system, while I/O nodes operate on a second, more punctual operating system. This design allows for more efficient generation and transmission of control commands, enhancing the overall performance of the control system.
