This manual will support the installation of both in-pavement and surface mount models of the sensor, VSN240-F and VSN240-S respectively. The sensors use deviations in the earth’s magnetic field along three axes, to determine the presence or absence of a vehicle at the sensors location. Event information is then wirelessly transmitted back to an Access Point, AP240, which is responsible for analysis and further reporting.

Attn: Reviewing Engineer Federal Communications Commission 7435 Oakland Mills Road Columbia, MD 21046 RE: CONFIDENTIALITY REQUEST FOR EUT VSN240 (RP240 under Modular Approval) Wireless Magnetic Sensor, FCC ID# TDB-VSN240 To Whom It May Concern: This letter serves as an official request for confidentiality under FCC Rule Section 0.459. We have requested that the schematic diagrams required to be submitted with this application be withheld from public review. The circuitry implements the proprietary Sensys Nanopower Protocol (SNP), and the schematics should never get into the possession of our competitors. Please contact me if there is any information you may need. Sincerely, October 13, 2005 ______________________________________ Robert Kavaler

Rev Page 1 of 5 Request for Limited Modular Approval Sensys Networks, Inc is requesting a Limited modular approval for our VSN240 sensor and RP240 products. The RP240 implements the exact same circuit design as the VSN240, minus the magnetic sensors. They also run different software images. Below we have addressed and adhered to seven of the eight requirements of the Modular application criteria. The request for a limited approval opposed to a complete modular approval comes in regards to the shielding of our products (see question 1). Sensys Networks will retain total control over the final installation of both the VSN240 and RP240, as they will be factory tuned, and be installed in completely self contained units. Installation of the modular component will never be done by the customer, therefore, full compliance of the end product is always ensured. The labeling of either product will incorporate a label on the outside cover, that will define that device contains FCCID TDB-VSN240. 1. The modular transmitter must have its own RF shielding. This is intended to ensure that the module does not have to rely upon the shielding provided by the device into which it is installed in order for all modular transmitter emissions to comply with Part 15 limits. It is also intended to prevent coupling between the RF circuitry of the module and any wires or circuits in the device into which the module is installed. Such coupling may result in non-compliant operation. The EUT complied with all FCC Part 15 limits without ANY shielding, because our product does not depend on shielding to keep us within the standardized limits. Either device, VSN240 and RP240 is a complete standalone device, with no opportunity for coupling. 2. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with Part 15 requirements under conditions of excessive data rates or over-modulation. The VSN240 and RP240 have buffering in both the microprocessor and the radio. 3. The modular transmitter must have its own power supply regulation. This is intended to ensure that the module will comply with Part 15 requirements regardless of the design of the power supplying circuitry in the device into which the module is installed. The power supply for the transmitter does have its own power regulator. 4. The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204(c). The antenna must either be permanently attached or employ a “unique” antenna coupler (at all connections between the module and the antenna, including the cable). Any antenna used with the module must be approved with the module, either at the time of initial authorization or through a Class II permissive change. The “professional installation” provision of Section 15.203 may not be applied to modules. Both the VSN240 and RP240 utilize the same permanently attached antenna, which has been has been tested and passed all FCC limitations. 5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in Section 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites; unless they will be marketed with the module (see Section 15.27(a)). The length of these lines shall be length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified or commercially available (see Section 15.31(i)). It was tested in a stand alone configuration, with a battery (without any ferrites) providing DC power. 6. The modular transmitter must be labeled with its own FCC ID number, and, if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: XYZMODEL1” or “Contains FCC ID: XYZMODEL1.” Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. The modular transmitter will be printed on the circuit board, and both the cases for the VSB240 and RP240 will have the necessary labeling. 7. The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. For example, there are very strict operational and timing requirements that must be met before a transmitter is authorized for operation under Section 15.231. For instance, data transmission is prohibited, except for operation under Section 15.231(e), in which case there are separate field strength level and timing requirements. Compliance with these requirements must be assured Both devices are factory tuned, and require no special instructions. 8. The modular transmitter must comply with any applicable RF exposure requirements. For example, FCC Rules in Sections 2.1091, 2.1093 and specific Sections of …

Exhibit 7 External Photos Figure 1 VSN240-F Flush Mount Sensor Figure 2 VSN240-S Surface Mount Sensor

Exhibit 19 Label and Location

The figure below represents a circuit board with an antenna, and one without. As one can see, there are no components located below/underneath the antenna.

Exhibit 2 Operational / Technical Description The circuit provides three main functions: general purpose micro-processor, rf transceiver and magnetic sensors. Each circuit has its own power supply and regulator, and corresponding filter and noise-reducing capacitors. The microprocessor controls the rf transceiver and the magnetic sensors. The microprocessor is a TI MSP430F149, the rf transceiver is a Chipcon CC2420 802.15.4 compliant transceiver in the 2.4 GHz ISM band. The magnetic sensors is a circuit made up of analog circuit components and Honeywell magnetic sensors. The devices start by listening on the RF transceiver for a packet from an access point device. Upon receiving this packet, the device starts sampling the magnetic sensors. The magnetic sensor data, either in raw format or processed format, is then transmitted by the device using the RF transceiver. The antenna is a ceramic patch antenna, loaded monopole antenna, or a slot antenna. In any case, one side of the PCB is ground, acting as the ground plane for the antenna. The unbalanced antenna output operates at 50 ohm impedance.

Description of Product as Marketed VSN240-s WIRELESS SENSOR VDS240 Wireless Vehicle Detection System In-Pavement Wireless Vehicle Sensor Measures Deviation of Earth’s Magnetic Field Traffic Count, Speed, Vehicle Presence & Type Freeways, Intersections, Parking Lots & Gates Rapid Deployment & Updates “Over the Air” The Sensys Networks VSN240-s is an in-pavement wireless vehicle sensor designed for both permanent and temporary deployment in all traffic conditions, from freeways to intersections to parking lots to gates. The VSN240-S detects vehicular traffic and reports it back to an AP240 access point. The VSN240-s measures the X, Y and Z components of the Earth’s magnetic field and analyzes these components to determine the presence or absence of a vehicle at its location. In a typical freeway count station application, one VSN240-s is deployed in each lane of traffic. Where individual vehicle speeds are desired, two VSN240-s devices can be deployed in each lane at a known distance from each other, typically 2m, in a manner similar to current inductive loop deployment. The VSN240-s can be glued, using a custom two-part adhesive, to the surface of the pavement similar to a raised pavement marker, or in regions where snow plow activity prohibits surface deployment, in a depression in the pavement or even buried under the pavement (see VSN240-f). Data Collection and Reporting The VSN240-s measures the Earth's magnetic field using a magneto resistive sensor, sampled at 128Hz. The VSN240-s automatically computes the “baseline” magnetic field (called “off”), and reports deviation of this field from this baseline at the presence of a vehicle (called “on”). The VSN240-s synchronizes its sample clock with the AP240, and therefore the data collected from one VSN240-s can be compared against another VSN240 to determine the length and the speed of a vehicle. There are three modes of operation: Event Mode, Data Mode, and Sleep Mode. The mode of operation and the parameters of operation can be selected from the AP240. In event mode, a sequence of off-on and on-off events is transmitted to the AP240 in a packet. The latency, number of events, minimum reporting interval, maximum reporting interval, synchronization of reporting, and other parameters are selectable via the AP240. In data mode, the actual output samples of the magnetic sensor are reported to the AP240. Reporting is performed in packets representing 125ms of data (16 samples) for the X, Y, and Z axes of the Earth’s magnetic field. In sleep mode, no data is reported to the AP240, saving power in the VSN240-s. Wireless Interface The VSN240-s implements the Sensys Nanopower Protocol, a TDMA protocol that allows for both high performance and long battery lifetime. Each VSN240-s is individually addressable, and transmits its data in a time-slot assigned by the AP240. Messages can be sent by the AP240 to set parameters on the VSN240-s, and to send commands to the VSN240-s such as changing its mode of operation. Up to 32 VSN240-s can operate on a single radio channel reporting with a minimum reporting interval of 125ms. More VSN240-s can be deployed by either using an additional AP240 on a different channel, or by increasing the minimum reporting interval. Another major feature of the VSN240-s is that its firmware can be updated “over the air” to ensure that the installed base of detectors can benefit from feature enhancements and software bug fixes. Recommended distances between an AP240 access point and the VSN240-s are as follows: AP240 Recommended Maximum AP240 to VSN240-f 12ft (4m) 75ft (25m) 18ft (6m) 105ft (35m) 24ft (8m) 150ft (50m) VNS240-s Dimensions: Length: 13.6 cm | 5.35 inches Width: 9.2 cm | 3.6 inches Height: 2.2 cm | 0.9 inches RF Specification IEEE 802.15.4 Standard Compliant Radio 2.4GHZ ISM Band Programmable Event Reporting Parameters Transmit Interval in seconds: 0.125, 0.25, 1, 2, 3, 5, 6 Reporting Latency in seconds: 0.125, 0.25, 0.5, 1, 2, 5, 10, 30 Durability Expected in-pavement lifetime of 5 to 7 years, depending on traffic volume.

Where individual vehicle speeds are desired, two VSN240-f devices can be deployed in each lane at a known distance from each other, typically 2m, in a manner similar to current inductive loop deployment. The VSN240-f is installed flush with the pavement surface in a 2” deep cored hole. Installation can be completed in less than 15 minutes. Data Collection and Reporting The VSN240-f measures the Earth's magnetic field using a magneto resistive sensor, sampled at 128Hz.
