Latest Patents

Onozato's latest patents include innovative solutions for preventing overheating and excessive current flow in vehicle daytime running lights. One of his inventions is a protection circuit that safeguards a switching transistor from overheating. This circuit disconnects the transistor from the power source when it detects temperatures exceeding a predetermined threshold. This proactive measure prevents excessive current from damaging the transistor, which could lead to hazardous situations such as fires. Unlike previous protection circuits that only controlled the gate of a MOSFET or the base of a BJT, Onozato's design effectively open-circuits the conductive path, ensuring safety and reliability.

Another significant patent involves a protection circuit that prevents excessive current flow through a field effect transistor due to short loads. This invention utilizes commonly available components, such as resistors and transistors, to create a cost-effective solution. The circuit includes a latching mechanism that keeps the switching transistor turned off once the current exceeds a specified level, preventing the daytime running light from flashing erratically.
