Sensor Long Valve & Short Valve FCC ID:GQ4-67T Canada IC:1470A-48T Model #:209624-125, -126 GENERAL DESCRIPTION This transmitter is a transmitter device with tire valve, which is mounted in the valve hole of the wheel rim and transmits the pressure and temperature inside the tire, the battery voltage of the transmitter, and the tire identification code (ID) at normal and abnormal condition with the radio wave (RF) that conforms to the used area. Also this device has a countermeasure function such as the random delay of transmission time so that the RF signal from each tire will not interfere such as due to the simultaneous transmission.

RE:TRWAutomotive FCCID:GQ4-67T IC:1470A-48T ATCB014823 The following is in response to the comments made on the above referenced application. 1)Accordingto15.231(a)(4)–Fordevicesusedforemergenciesforsafetyoflife,thedevice mayTXmorefrequentlybutonlyduringthependencyofthealarmcondition.Thisusually expects sensorstotriggertheset/unsetevents.Pleaseexplainasthealertmodeappears toTXfor 1minute(timedduration–vseventtriggered/untrigged). The DUT is a tire pressure sensor. In the alert mode, the DUT is stated to transmit continuously for 60 seconds if triggered by a severe tire pressure change or high temperature event. In the event of such an emergency, the sensor transmits RF packets which must be received by the in-vehicle receiver. This receiver in turn sends data to the vehicle body control module, and then a warning is passed on to the vehicle driver. The driver must then stop the vehicle, inspect the tire's pressure and temperature, correct the pressure, wait for the tire to cool down, or possibly have the tire replaced in order to end the emergency. Once a potential emergency is detected, the emergency state persists until a human confirms there is no longer an emergency. After 60 seconds, the normal periodic transmission, temperature, and pressure sampling resumes. It is inconceivable that a vehicle operator could perform all the tasks necessary to ensure they have eliminated the emergency condition in less than 60 seconds, the sampling rate of the sensor. 2)Section2.1.2seemstoconflictwith 1)aboveandoperationaldescription (i.e.alertmodes), i.e.citesneverlessthan10seconds. Section 2.1.2 details the two key modes of operation tested, not all the modes of operation for the device. The Description of Operation exhibit details all the operating modes for consumer use.
