Re: Certification for TRW Transmitter FCC ID: GQ4-44T IC: 1470A-25T 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.

Block Diagram includes internal oscillator frequency information that the manufacturer considers to be proprietary. Permanent Confidentiality: TRW requests the exhibits listed above as permanently confidential be permanently withheld from public review. Short-Term Confidentiality (FCC Only): TRW requests the exhibits selected above as short term confidential be withheld from public view for a period of 45 days from the date of the Grant of Equipment Authorization and prior to marketing.

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 due to the simultaneous transmission. The transmitter device also has a Low Frequency (LF) receiver. This receiver supports Low Frequency (LF) m agnetic field communi cations allowing the changing of measurement/monitoring states o f the transmitter b y commands sent via the TPM diag nostic tool. The RF sig nal operates at 315MHz and uses FSK M anchester code m odulation. 225816-101 transmits 4 RF p ackets every 200 seconds. Description of Operations Mode of Operation Explanation Frequency of Transmission Storage Mode No transmission. Measures temperature & pressure 4 words when activation occurs with TPM diagnostic tool Normal Mode Measures temperature and pressure. Transmits periodically. Enters this mode from storage when pressure goes above threshold.  4 words every 210 seconds  4 words when activation occurs with TPM diagnostic tool Alert Mode Transmits when: a) significant pressure delta detected b) high temperature is detected 8 words every 4 seconds for 1 minute

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: GQ4-44T, IC: 1470A-25T. This device under test (DUT) is subject to the rules and regulations as a Transmitter. In testing completed on January 25, 2010, the DUT tested met the allowed specifications for radiated emissions by 0.5 dB. Conducted emissions are not subject to regulation as the DUT is powered by a 3 VDC battery.

Introduction This TRW Transmitter was tested for compliance with FCC Regulations, Part 15, adopted under Docket 87-389, April 18, 1989 as subsequently amended, and with Industry Canada RSS-210/Gen, Issue 7, June 2007. Tests were performed at the University of Michigan Radiation Laboratory Willow Run Test Range following the procedures described in ANSI C63.4-2003 "Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz". The Site description and attenuation characteristics of the Open Site facility are on file with FCC Laboratory, Columbia, Maryland (FCC Reg. No: 91050) and with Industry Canada, Ottawa, ON (File Ref. No: IC 2057A-1). 2. Equipment Used The test equipment commonly used in our facility is listed in Table 2.1. Except where indicated as a pre- test, monitoring, or support device; all equipment listed below is a part of the University of Michigan Radiation Laboratory (UMRL) quality system. This quality system has been established to ensure all equipment has a clearly identifiable classification, calibration expiry date, and that all calibrations are traceable to national standards.
