Hiroshi NAGAHISA has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Control system, logic module substrate, and logic FPGA
    Patent number: 8581626
    Abstract: According to an embodiment, a control system has: a logic module substrate that has a logic FPGA on which logic is mounted, a transmission module that transmits an output logic state signal, which is logic state signal representing an interim logic state of a process by the logic FPGA of deriving a logic output signal from the logic input signals, and a logic monitoring device that displays to monitor the logic state signal transmitted from the transmission module. The logic module substrate includes an event detection unit that detects a change in the logic state signal. Only when a change in the logic state signals is detected by the event detection unit, the logic output state signal being transmitted to the transmission module.
