A tire condition detecting device includes a controlling section that determines whether there is an anomaly in the tire based on the condition of the tire detected by the condition detecting section. A protocol that is designated by a trigger device is defined as a first protocol, and protocols that are not designated by the trigger device are defined as second protocols. When determining that there is no anomaly in the tire, the controlling section causes the transmission section to transmit only the data signals using the first protocol. When determining that there is an anomaly in the tire, the controlling section causes the transmission section to transmit the data signals using the second protocols in addition to the data signals using the first protocol.

A method includes operating a transceiver of a tire pressure monitoring system in an active operation mode, where the transceiver includes a battery and a data storage device. The method includes determining whether the transceiver is coupled to an external power source, and determining whether the data storage device of the transceiver includes sensor identifier data stored thereon when the transceiver is not coupled to the external power source. The method further includes transitioning the transceiver from the active operation mode to a battery storage mode when the data storage device does not include sensor identifier data stored thereon and the transceiver is not coupled to the external power source.

A method for operating a monitoring device for at least one vehicle parameter, in particular an air-pressure sensor for the tire-pressure vehicle parameter. The monitoring device is operated in a drive mode or in a stationary mode as a function of the velocity of the vehicle. Connection signals for the wireless connection to an external device, in particular a configuration device for the monitoring device, are transmitted in the stationary mode. Prior to the change to the stationary mode, the monitoring device is operated in a first intermediate mode. A passive search for wireless connection signals from the external device is carried out in the first intermediate mode.

A method of configuring a tire monitoring device including, at the tire monitoring device: entering a configuration mode; responsive to entering the configuration mode, transmitting a first message to a second device, the message indicating that the second device should transmit configuration data to the tire monitoring device; receiving configuration data from the second device in response to the first message; and configuring the tire monitoring device based on the configuration data.

A mode-swappable tire pressure detection system and a method of operating the same are provided and applied to tires of motor vehicles. The mode-swappable tire pressure detection system has a tire pressure detector. The tire pressure detector has a memory module. The memory module is configured with sensing modes, rendering the tire pressure detector capable of switching between different sensing modes. When a user issues a control instruction to a host or the tire pressure detector, the tire pressure detector can switch between different sensing modes through the memory module.

In a method for controlling a processor on a wheel, wheel operation parameters are calculated and transmitted to a CPU. A first default operating mode (standby mode) is defined, during which activities related to calculating and checking the characteristic data of the tread mark of the tire are deactivated, a second operating mode for detection of significant changes in the value of a characteristic datum of the tread mark, sought during the appearance, in standby mode, of at least one event likely to be preceded by a significant change in the value, and a third operating mode for calculation and transmission, to a CPU, a sequence of values representing the characteristic datum of the footprint, sought during the confirmation, in detection mode, of a significant change in the value of the characteristic datum of the tread mark, and at the end of which a switch is made into monitoring mode.

To provide a circuit with low power consumption, a semiconductor device with low power consumption, a highly reliable semiconductor device, a tire whose performance is controlled, a moving object whose performance is controlled, or a moving object with a high degree of safety. A tire provided with a semiconductor device is provided. The semiconductor device includes a circuit portion, an antenna, and a sensor element. The circuit portion includes a transistor. The transistor includes an oxide semiconductor. The sensor element is configured to measure the air pressure of the tire.

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.

A system includes a millimeter-wave radar sensor circuit configured to be fastened to a wheel having a tire, and a controller. The millimeter-wave radar sensor circuit is configured to transmit a radio-frequency (RF) signal towards a portion of an inner surface of the tire and receive a reflected signal from the tire. The controller is configured to process the reflected signal, determine a property value of the tire based on processing the reflected signal, and generate and transmit a first signal representative of the property value of the tire.

Method and apparatus are disclosed for real-time activation of tire pressure measurement systems. An example vehicle includes a communication module and a tire pressure measurement system (TPMS) including a TPMS sensor and a controller. The controller is to determine, responsive to receiving an update request, whether the TPMS sensor is paired with the communication module. The controller also is to, responsive to determining the TPMS sensor is not paired, activate the TPMS in a real-time mode, collect a current measurement from the TPMS sensor upon activation, and present the current measurement.
