Latest Patents

One of his latest patents focuses on monitoring and protecting drives controlled with a microcontroller. In this system, overcurrent is detected by comparing the total current through the device with a stored level. If the detected current is excessive, the devices are independently activated, and the current through each device is compared with the stored current level for that device. A device experiencing an overcurrent condition is inactivated while the remaining devices continue to operate. Another significant patent involves monitoring the characteristics of a load driver controlled by a microcontroller. In this setup, loads such as power relays for wipers, windows, and lights are connected to an automobile battery through individual transistor drives. The microcontroller checks the load characteristics when each drive is activated and inactivated, ensuring proper functionality.
