  • Patent number: 11067506
    Abstract: A hydrogen storage metal is disposed on a base material in a predetermined shape and a predetermined size such that hydrogen is detected based on surface plasmon resonance induced by incident light.

  • Patent number: 8451091
    Abstract: The present invention provides, as one aspect, a control system having sensor units and an electronic control unit. The electronic control unit includes a transmission controlling means which sets a signal line connected to the sensor unit, which is a destination of communication data, to a first state, sets the signal line connected to the sensor unit, which is not the destination, to a second state, and transmits the communication data to the destination via a communication line. The sensor unit includes a reception controlling means which determines a state of the signal line connecting a sensor to the electronic control unit. When determining that the signal line of the sensor unit is in the first state, the reception controlling means receives the communication data and performs a predetermined process. When determining that the signal line is in the second state, the reception controlling means discards the communication data.
