The Surface Display with Silent Zone Transmitter is mounted on a vehicle or piece of machinery and is connected to a central control unit. 1.1 Theory of Operation The functions of the Surface Display with Silent Zone Transmitter are:  To transmit a 73 kHz “Silent Zone” field around a small portion of the vehicle or piece of machinery in which the operator is allowed to safely work or enter as part of his normal activities.  To provide a visual and audable indication to the operator as to the status of the HazardAvert system in relation to this particular vehicle or piece of machinery. The Surface Display with Silent Zone Transmitter is connected to the HazardAvert Central Controller, which under the control of a microcontroller, generates a 73 kHz signal for creating a Silent Zone around the area of a machine where the Display and Operator are located. This 73 kHz signal is connected to the Surface Display with Silent Zone Transmitter along with other signals via a wire bundle connected to a bulkhead connector on the housing of the Surface Display. Inside the Surface Display with Silent Zone Transmitter housing is a wire / ferrite radiator element to which the 73 kHz signal is connected. The 73 kHz signal passing through this wire / ferrite radiator element generates a 73kHz “Silent Zone” electromagnetic field which encompasses only the small area of the vehicle or machine in which the operator can safely be during operation. The operator is required to wear a Personal Alarm Device (PAD) which is another component of the HazardAvert system which detects and responds to the presence of 73 kHz fields. As long as the operator is within this “Silent Zone” his PAD will know he is within a safe area. If the operator exits this Silent Zone safe area, his PAD will function to alert him and other machines or vehicles equipped with the HazardAvert system of his proximity to dangerous conditions due to his distance from machine or vehicle hazards. The Surface Display with Silent Zone Transmitter also indicates to the operator the status of the system via a series of LEDs. There is an LED which indicates that the system is powered, an LED that indicates if there is an individual or other machinery close enough to warrant a “Warning” condition and another LED that indicates if there is an individual or other machinery close enough to Confidential Patent #’s 7,420,471 5,939,986 and 6,810,353 Patent Pending Page 4 of 7 Strata Proximity Systems Surface Display with Silen Zone Users Manual v1.0 Confidential and Proprietary October 19, 2011 warrant a “Danger” condition. The Surface Display also has a LED to indicate if there is a bus communication failure with the Central Controller. The Surface Display also has 4 LEDS which in the case or a Warning or Danger condition, indicate which Surface Proximity Modules (another component of the HazardAvert System) are detecting the Warning or Danger condition. There is also a sounder on the Surface Display with Silent Zone Transmitter which creates audible alerts to the operator of a Warning or Danger condition. The Surface Display with Silent …

Response to ATCB Comments FCC ID: ZQ3-SPS-SDMOD 1 Washington Laboratories, Ltd. 7560 LINDBERGH DRIVE GAITHERSBURG, MD 20879 (301) 216 - 1500 FAX # (301) 216 - 1590 November 9, 2011 Mr. Richard American Certification Body Inc. 6731 Whittier Ave McLean, VA 22101 RE: Comments of November 4, 2011 APPLICATION: ZQ3-SPS-SDMOD, Strata Proximity Systems, LLC. Dear Mr. Fabina: Below are the comments that you have provided regarding the application for certification referenced above. Our responses to those comments are in bold italic. Many responses refer you to additional exhibit(s) which has been uploaded to the application folder at the ATCB website. Thank you for your attention. Please feel free to contact us for any additional information that you may require. Regards, Steven D. Koster VP, EMC & Wireless WLL Project: 12034 1) What is your justification for not providing AC line conducted emission test results showing compliance with Section 15.207(a) of the FCC Rules? The test set up diagram in Section 2.2 of the submitted test report shows the EUT being powered from a support fixture which in turn draws its power from the AC mains. I see no battery connector or battery inside the support fixture photographs. Finally the submitted schematic diagram shows a connection in the support fixture for 120 or 240 VAC. It is possible that this device is powered by battery but I see no supporting documentation. The last sentence from paragraph c of Section 15.207 of the FCC Rules states “Devices that include, or make provisions for, the use of battery chargers which permit operating while charging, AC adapters or battery eliminators or that connect to the AC power lines indirectly, obtaining their power through another device which is connected to the AC power lines, shall be tested to demonstrate compliance with the conducted limits.” In my opinion, AC line conducted test results must be submitted for this device. Please comment/clarify. (I do have an interpretation that will allow you to test this device to the Class A AC line conducted emissions limits. It is the third attachment to this email). Response to ATCB Comments FCC ID: ZQ3-SPS-SDMOD 2 R. AC line conducted emissions were not performed because the unit is intended to be installed on a vehicle per the installation manual and the information provided by the client. The fixture that was used was for testing purposes only. 2) Radiated emission test results in Tables 6 and 7 of the submitted test report are for 10 and 3 meter test distances respectively. Section 4.2.1 of the report does not make it clear that both distances are being used. This section only mentions a 10 meter test site. Please address. . R. Test distances clarified in the Rev 1 report.
