Patent number: 10216162Abstract: In order to make it possible to diagnose an operation state of a fluidic device despite reducing the size of the fluidic device, a relay is configured to include a first port connected with the fluidic device and a second port connected with a user information processor, and receive fluid-related data from the fluidic device via the first port and transmit the data to the user information processor via the second port, or receive the data from the user information processor via the second port and transmit the data to the fluidic device via the first port. In addition, the relay includes a third port that is connected with a diagnostic apparatus adapted to diagnose the operation state of the fluidic device, receive diagnostic data from the fluidic device via the first port, and transmit the diagnostic data to the diagnostic apparatus via the third port.Type: GrantFiled: June 19, 2015Date of Patent: February 26, 2019Assignee: HORIBA STEC, Co., Ltd.Inventors: Kotaro Takijiri, Kenichi Oe, Yukimasa Furukawa
