(5) Schematics

(10) Parts List (Part of Exhibit only) Pursuant to 47 CRF 0.459, Delphi Delco requests that a part of the subject application be held confidential. This comprises Exhibits Delphi Delco 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.

(5) Internal Photos Delphi Delco requests that a part of the subject application be held short-term confidential. This comprises Exhibit(s) The device in question will not be available to the consumer until the 2007 automotive model year. Thus, Delphi Delco requests that the internal photos not be made public at this time. Delphi will continue to request the short-term confidentiality every 45 day period, up to 180 days from the date of grant, as necessary.

Valdis V. Liepa Subject: RE: 15.515 / 15.521 Measurements Question:

If the peak detected emissions from a device meet the RMS EIRP limits, with all Spectrum Analyzer settings identical to the requested RMS detected method except with peak detection, is that sufficient to demonstrate compliance with said limits? (Since the peak detected values will always be greater than the RMS detected values for every bin of the spectrum analyzer output.) Our Spectrum Analyzer does not have the built in RMS detector function and, so long as the device meets the EIRP limits with a peak detector, we prefer not to use the alternative method for determining RMS values as it is an exceptionally long and complicated test. Answer:

Yes, you can use a peak detector. Use of a peak detector is sufficient to demonstrate compliance with the RMS limits. 10/12/2004

Radar System Design

Design Drivers Small targets at 5 meters distance : Good system detection sensitivity Precision Ranging capability : MUST have large radiated bandwidth Wideband FCC frequency allocations demand very low transmitter power Low transmit power + good system sensitivity means Sensitive receiver required Efficient waveform for detection is necessary

Waveform noise code Continuous Wave radiation modulated in phase by a high speed pseudo Phase modulation is binary phase shift key (BPSK) Code modulated continuous wave provides efficient waveform and good range precision Delco Electronics Systems Proprietary Principles of Operation

Range Bin Definition As a target range (time delay) varies slightly about the time (range) delay imparted to the receive code, the receiver output (voltage) varies to less than maximum. The range response of the system for a fixed return signal power is as follows t u p t u o r e v i e c e r range Rn Delco Electronics Systems Proprietary Principles of Operation

The POSITION of the range bin in space is determined by the time delay of the receive code The entire range is covered by scanning the single range bin in range Scanning is accomplished by adjusting the time delay value of the receive code

The WIDTH of the range bin (depth of bin in space) is determined by the period of one bit of the pseudo noise code sequence high speed code clocks = thin range bins Delco Electronics Systems Proprietary Principles of Operation

Achieving Receiver Sensitivity Direct detection of the LO signal which comes out of the receive phase modulator cannot provide adequate receiver sensitivity The transmit LO signal is further modulated by a data stream to provide an AC signal after down conversion for detection.

Diagnostics There is an End to End diagnostic function implemented, which gives very high coverage of detecting failures This feature is accomplished by positioning the system range bin such that it contains the transmit and receive antennas. Direct coupling between antennas provides a reliable signal injection into the receiver range bin positioned over antennas with the proper delay value LO with
