Re: Certification for TRW Transmitter FCC ID: GQ4-45T IC: 1470A-26T REQUEST FOR CONFIDENTIALITY Pursuant to FCC 47 CRF 0.457(d) and 0.459 and IC RSP-100, Section 10, TRW requests that a part of the subject application be held confidential. TRW has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship.

March 17, 2010 RE: ATCB008782 – Original Equipment & New Family Certification Applications (models 226196 & 226204) FCC ID: GQ4-24T & IC: 1470A-26T for TRW, Inc. The following is in response to the comments made on the above referenced application. 1. In the equipment label exhibit, Figure 2 has the wrong FCC ID number shown. Please provide a new equipment label exhibit with the correct FCC ID number shown in both Figure 1 and Figure 2 labels. There was a mistake in one of the drawing provided that resulted in an error in the paperwork provided. Both the label drawing and the associated paperwork has been updated to reflect the correct FCC ID: GQ4-45T. 2. In Table 6.1 of the submitted test report, there appears to be a note missing from the value of E3 stating that the duty cycle correction factor of -16 dB has been included in the reported value. Please correct this omission from the test report exhibit. The table has been corrected to include the duty cycle employed. 3. The operational description exhibit states that this device has an LF receiver as follows “This receiver supports Low Frequency (LF) magnetic field communications allowing the changing of measurement/monitoring states of the transmitter by commands sent via LF trigger tool, special hand held tool (LF transmitter). The RF signal operates at 315MHz and uses FSK Manchester modulation.” What is the operating frequency of the receiver contained in this device? (The last sentence in quotes seems to say that this receiver is a 315 MHz receiver. IC would require receiver measurements on a receiver operating above 30 MHz. I don’t see any such measurements in the submitted test report). The DUT employs only a 125 kHz passive detector that can be used to interrogate the units 315 MHz transmitter. The 315 MHz receiver discussed is employed as a separate device in the vehicle.

The ASIC outputs the measured data in digital pulses. The digital data gates on and off a power amplifier which couples the RF carrier to the antenna. The transmitted signal uses Frequency Shift Keying (FSK). The carrier frequency of the sensor is 315MHz typically. The worst case frequency shift of the carrier is 314.77MHz for the low frequency and 315.15MHz for the high frequency shift. The receiver bandwidth must be wide enough to pass the transmitter worst case frequency shifts.

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. The transmitter device also has a Low Frequency (LF) receiver. This receiver supports Low Frequency (LF) magnetic field communications allowing the changing of measurement/monitoring states of the transmitter by commands sent via LF trigger tool, special hand held tool (LF transmitter). The RF signal operates at 315MHz and uses FSK Manchester modulation.

Brunett Research Scientist Summary Tests for compliance with FCC Regulations, CFR 47, Part 15 and with Industry Canada RSS-210/Gen, were performed on a TRW, FCC ID: GQ4-45T, IC: 1470A-26T . This device under test (DUT) is subject to the rules and regulations as a Transmitter. In testing completed on January 19, 2010, the DUT tested met the allowed specifications for radiated emissions by 7.5 dB. Conducted emissions are not subject to regulation as the DUT is powered by a 3 VDC battery.
