The sensor unit can be cleaned with water and a mild detergent. 6 Theory 6.1 Theory of Operation The Utility Scanner uses ground penetrating radar (GPR) to characterize the surface beneath the sensing unit. The GPR sends a low-energy impulse of electromagnetic (EM) energy towards the surface. Some of this energy penetrates into the subsurface and some is reflected back towards the sensor unit. The amount of reflected energy depends on the contrast in dielectric constant and electrical conductivity of the soil and embedded objects. By measuring the travel time of these waves, the depth to the reflectors can be determined in a manner analogous to a fish finder. By moving the scanner over the surface and detecting object beneath it, a 2D or 3D cross section of the subsurface can be obtained. High frequency radar waves (i.e. 750 MHz) provide better spatial resolution than lower frequency radar waves, but they attenuate quickly as the travel through the subsurface. Subsequently they cannot detect objects deeper than about two feet. Lower frequency radar waves (i.e. 350 MHz) are able to penetrate more deeply (to about 20 feet) but do not provide as much detail in the subsurface images. Copyright 2019 ESS, LLC.

Advanced users may choose to change these settings (see Figure A1). To view or change the digitizer settings, select (File, Settings). 1. Trace Sample Rate Select the desired number of traces per second. Using fewer traces per second gives a higher signal to noise ratio and increased depth of investigation. However fewer traces per second will result in fewer traces per foot (meter) at a given traverse speed. 2. Sample Rate Select the sample rate used for each A-scan. Normally a sample rate of 8 GHz is used for antennas with center frequencies less than 1 GHz, and 16 GHz is used for antennas with center frequencies greater than 1 GHz. 3. Num Samples Select the number of samples for each A-scan. A value of 512 samples will work for most situations. Note that using a large number of samples (1024 or more) may limit the Trace Sample Rate. 4. Channel A/B Holdoff The GPR digitizer has two channels: A and B. The holdoff time can be adjusted independently for each channel. The B channel can only be adjusted in 4 ns increments relative to the A channel. Normally, users will not need to change these values. Figure A1. Digitizer settings dialog. 7.2 Software Installation If the tablet computer has not yet been setup for use with the Utility Scanner, proceed as follows.

HDF5 allows storage of large datasets in complex data structures. In addition to the data stored in an HDF5 file, the files provide all of the data type and format information needed for reading the data. A helpful utility for quickly browsing HDF5 file is the HDFView utility which is freely available from the HDF5 Group (https://www.hdfgroup.org/downloads/index.html). The HDF5 Group provides free software interfaces for HDF5 in most popular computer languages including Fortran, C, Java, Python, and Matlab. Figure A3 is a screenshot from HDFView showing the contents of an H5 file recorded by the sonic logging system. On the left is a tree structure that lists the datasets in the file. The JobInformation dataset contains information about the jobsite. There is a folder for each data server (e.g., gpr4, odometer, gps, etc.), and each folder contains configuration information and data. As shown below, the detailed format of each dataset is included in the file. This self-describing feature of HDF5 files along with the open software interfaces allows the data to be easily read by user-developed software. Copyright 2019 ESS, LLC. All rights reserved.

Application Examiner and Reviewing Engineer Re:

Request for confidentiality of internal photos Applicant:

Earth Science Systems, LLC FCC Grantee Code is: 2AP78 IC Company Code is: 24708 FCC ID:

IC:

2AP78-US1 24708-US1 To whom it may concern:

Earth Science Systems, LLC (ESS) requests that certain portions of the application for equipment certification for the referenced FCC identifiers are permanently withheld from public disclosure. Specifically, with reference to FCC Rules Sections 0.457(d) and 0.459 for requesting confidentiality, the following sections of the application are requested to be kept confidential. Exhibit Type Schematics Block Diagrams Operational and Functional Description Internal Photos File Name ESS Utility Scanner - Schematics.pdf ESS Utility Scanner - Block Diagrams.pdf ESS Utility Scanner - Operational Description.pdf ESS Utility Scanner - Internal Photos.pdf The rationale for request for confidentiality is that the information listed above is Trade Secret and is not normally released to anyone outside the company. ESS has invested considerable time and materials in research and development to produce the referenced product. Disclosure of the confidential portions of this application to competitors would not only give them significant competitive advantages in developing similar products, but would also disclose successful implementation of unpublished leading-edge technology developed by ESS. With regard to the internal photos, the Commission usually denies confidentiality of internal photograph on the grounds that the information in the photos can be obtained by competitors who purchase and disassemble the device. However, ESS requests that the internal photos are held confidential for the following reasons. 1. The device is sealed and its internal appearance is not accessible to purchasers of the device. Disassembly of the product by individuals outside our organization would almost certainly result in irreparable damage to the unit and render it nonoperational. The products enclosure is permanently sealed with industrial strength adhesive, and opening the enclosure would require cutting into the unit. 11485 W. I-70 Frontage Rd., Unit B Wheat Ridge, CO 80033 (303) 800-2000 Additionally, the screws holding the housing together have been glued in place and opening the housing would require drilling out the screws, which poses a substantial risk of permanent damage. 2. Disassembly of the product by individuals outside our organization will likely result in permanent damage to the antennas and shield assembly because the antenna elements, radar absorbing foam, pre-amplifiers, and pulsers are glued and soldered together. Disassembly would result in damage to the foam and possibly the circuit boards. Persons outside our organization would not be able to determine the type of foam needed for repair. 4. 3. The product does not contain user serviceable components. Notices are placed on the instrument warning that there are not user serviceable components inside the unit and that disassembly voids any warranties. ESS has never released disassembly instructions and does answer question regarding disassembly. The design of internal components are Trade Secret. If the photos were made public, it would give competitors access to critical components of the products design, in which ESS has invested a considerable amount of time and expense. A knowledgeable person would be able to identify and reverse engineer critical components of the system, and possibly produce a schematic diagram. A knowledgeable person would be able to estimate the manufacturing costs and man-hours needed for assembly. The Commission has previously granted confidentiality under similar conditions to the following applications: FCC ID QLA250MHZ, FCC ID QLAMID, FCC ID QLA500MHZ, FCC ID QLA800MHZ, FCC ID OPLQ5C, FCC ID OPLQM1020, FCC ID OPLQ4-300, FCC ID OPLQ5C, FCC ID QF7PALXMT, FCC ID QF750350US, FCC ID QF742600, FCC ID QF7MINIXT, and FCC ID QF7350HS. Furthermore, the legal basis of our request can be found in the following references:

McDonnell Douglas Corp. v. NASA, 180 F.3d 303, 304-05 (D.C. Cir. 1999), quoting Critical Mass Energy Project v. NRC, 975 F.2d 871, 879 (D.C. Cir. 1992)(en banc).
