Patent number: 10864784Abstract: A transmitter is mounted on each of a plurality of wheel assemblies included in a vehicle. The transmitter executes a process in accordance with a command included in a trigger signal. The transmitter includes a pressure sensor that detects the tire pressure, a transmission unit that transmits a data signal including a detection result of the pressure sensor to a receiver, a trigger reception unit that receives the trigger signal, and a controller that controls the transmitter. When the trigger reception unit receives the trigger signal including a command shifting a state of the transmitter to a standby state, the controller shifts the state of the transmitter to the standby state. Further, when the trigger reception unit receives the trigger signal including a command designating a mode while the state of the transmitter is the standby state, the controller sets the designated mode.Type: GrantFiled: December 1, 2017Date of Patent: December 15, 2020Assignee: PACIFIC INDUSTRIAL CO., LTD.Inventors: Takashi Takeyama, Takahito Obata
