Using sophisticated Global Positioning Satellite (GPS) technology, SkyGuard 500 provides timely information about an offender’s location, as well as his or her compliance with established boundaries and curfews. Corrections officers can monitor offenders from multiple locations, such as home, office, or car. The SkyGuard 500 consists of five main components: !"SkyGuard 500 Central Monitoring Station (CMS) !"SkyGuard 500 Transmitter (transmitter) !"SkyGuard 500 Tracking Pack (tracking pack) !"SkyGuard 500 Base Station (base station) !"SkyGuard 500 Global Tracking System (GTS) software 2 Central Monitoring Station The SkyGuard 500 Central Monitoring Station (CMS) is the heart of the tracking system. It performs the following functions: !"Stores the SkyGuard database and processes information received from the base station and tracking pack !"Generates alerts if it detects that someone has tampered with the transmitter, base station, or tracking pack. !"Automatically reports violations in the form of an alert. For example, if an offender leaves the house outside the permitted time, the base station sends this information to the CMS, which alerts you via pager or e-mail. Transmitter The transmitter is a waterproof, battery-operated bracelet that the offender wears around the ankle or wrist. It sends a signal to the belt pack, which recognizes the proximity of the transmitter, as well as the transmitter’s identification number, tamper condition, and battery status. Transmitter features include: !"Low-power, radio-frequency transmissions !"Field-replaceable battery !"Adjustable, hypo-allergenic, replaceable strap !"Waterproof to 15 feet !"Multiple tamper and low-battery sensors !"Weighs less than four ounces 3 !"Automatic tamper reset !"Encrypted transmissions which prevent signal replication Tracking Pack The SkyGuard 500 Tracking Pack is a battery-operated unit enclosed in a shoulder bag and typically worn on the offender’s body. Although the offender is not required to wear the tracking pack, to avoid an alert from being generated, the transmitter and tracking pack must remain within 30 feet of each other at all times. The tracking pack battery lasts approximately 16 hours and must be charged at the end of every day; the battery is charged by plugging the unit into the base station. The tracking pack is capable of storing position information about the offender. Therefore, if an offender’s position cannot be continuously monitored because of inconsistent cellular coverage, the tracking pack records GPS coverage information. This information is transmitted to the CMS when the offender plugs the tracking pack into the base station at the end of the day or when the tracking pack reenters cellular range. 4 Base Station The SkyGuard 500 Base Station is the link to the offender, while he or she is at home (wearing the transmitter), and the central monitoring station The base station is installed in the offender’s home and is connected to the home phone line. The offender uses the base station to charge the tracking pack battery. When an offender returns to his home at the end of the day, he or she plugs the unit into the base station and the tracking pack battery is recharged. Additionally, the base station transmits any information stored in the tracking pack to the CMS via the phone line. Features of the SkyGuard 500 Base Station include: !"Tamper detection sensors discourage unauthorized removal !"Back up battery that operates for up to 36 hours in the event of a power failure !"Detects up to 10 transmitters at one time !"Easy-to-configure, pro-active alert notification system !"Ability to define restriction zones 5 SkyGuard 500 Global Tracking System software The SkyGuard 500 GTS software lets you track offenders by accessing the application through your Internet browser. This means you can get position updates from any computer with an Internet connection – at home, in the office, even in your car. The software provides the fo…

Dear Sir or Madam Continental Divide Robotics, Inc. re!quest that certain materials submitted with this application for certification of the Model SG501 be withheld from public disclosure. This request is made under the provision s of Section O.457(d) of the Commission's Rule and Section 552 (b) (4) of the Freedom of Information Act, Trade Secrets. : The items marked "Confidential" j::ontain detailed block diagrams, schematics diagrams, word documents, and detailed theory of operation submitted to the FCC for review with this application. The information in this envelope contains proprietary information (trade secrets) regarding the circuit operation and capabilities (specific values of components, circuit design details and system architecture), which are the result of our extensive investment in research and development. Without the disclosed information, competitivE~ organizations would take considerable more time to assess and develop a workable competitive pro,duct. As a result, we believe that disclosure of these company guarded materials would compromise~ our leading position in this market. We therefore formally request that the materials named below that are contained in this envelope be kept strictly confidential and not made available for inspection by any other party, except on a need to know basis for the sole purpose of thE~ certification process.

March 19, 2001 Statement of Compliance with Ele<:tronic Serial Number (ESN) regulations The Electronic Serial Number (ESN) of the SkyGuard 500 model SG501 is set in the factory and a unique value is given to each device. The memory device storing the ESN is permanently soldered to the main circuit board. An encrypted version of the ESN is also stored in a different location in memory. Upon power up, the phone's microprocessor regenerates an encrypted version for the ESN locally using a proprietary algorithm and key known only to Sierra Wireless and compares it to the encrypted version in memory. If these values do not match, the phone is completely disabled and cannot be used in anyway. The ESN can be set only by configuration and maintenance personnel, and otherwise cannot be altered. transferred, removed, or otherwise manipulated. Any attempt to alter the ESN number or tamper with the firmware will render the phone inoperative. i 5255 S. Rio Grande Street Littleton, GO 80120 303-409-2990 fax: 303-707-0~54

March 19, 2001 IESN Protection Description The following measures have been taken to protect against fraud due to modification of the ESN or telephone software, in compliance with CF47, 22.919 ( 1) the stored ESN data in the FLASH device (which contains the information other than the ESN data) is encrypted. This ESN data is divided into four groups and interleaved with other data in the FLASH. (2) The ESN is never transferred in a readable format across wires on the print~ circuit board, nor can the ESN be read by probing the pins of any device. (3) If the NVM (or data in FLASH) is altered, then the ESN becomes invalid and the phone will not operate. (4) The FLASH device containing the main program software and encrypted ES~ data, is permanently attached t the circuit board by soldering. (5) The ESN write and change must be carried out at one of our manufacturing $ites using a dedicated interface tool using special software, and interface box, and a PC. This interface tool will not be supplied to and vendor/distributor. (6) To prevent fraudulent cloning and ensure that uniqueness of each ESN is protected, this product uses the Industry Standard Authentication Algorithm. This algorithm incorporates random challenges using shared secret data calculations to prevent cellular system fraud. 5255 S. Rio Grande Street Littleton, GO 80120 303-409-2990 fax: 303-707-0~54

64K x 16 Static RAM CY62127V Cypress Semiconductor Corporation •3901 North First Street•San Jose•CA 95134•408-943-2600 June 2, 1999 Features • 2.7V–3.6V operation • CMOS for optimum speed/power • Low active power (70 ns) — 198 mW (max.) (55 mA) • Low standby power (70 ns, LL version) —54 μ W (max.) (15 μ A) • Automatic power-down when deselected — Power down either with CE or BHE and BLE HIGH • Independent control of Upper and Lower Bytes • Available in 44-pin TSOP II (forward) Functional Description The CY62127V is a high-performance CMOS Static RAM or- ganized as 65,536 words by 16 bits. This device has an auto- matic power-down feature that significantly reduces power consumption by 99% when deselected. The device enters power-down mode when CE is HIGH or when CE is LOW and both BLE and BHE are HIGH. Writing to the device is accomplished by taking Chip Enable (CE ) and Write Enable (WE) inputs LOW. If Byte Low Enable (BLE ) is LOW, then data from I/O pins (I/O 1 through I/O 8 ), is written into the location specified on the address pins (A 0 through A 15 ). If Byte High Enable (BHE) is LOW, then data from I/O pins (I/O 9 through I/O 16 ) is written into the location specified on the address pins (A 0 through A 15 ). Reading from the device is accomplished by taking Chip Enable (CE ) and Output Enable (OE) LOW while forcing the Write Enable (WE ) HIGH. If Byte Low Enable (BLE) is LOW, then data from the memory location specified by the address pins will appear on I/O 1 to I/O 8 . If Byte High Enable (BHE) is LOW, then data from memory will appear on I/O 9 to I/O 16 . See the truth table at the back of this datasheet for a complete description of read and write modes.

First, a precision temperature-compensated reference and comparator circuit monitor the status of V CC . When an out-of-tolerance condition occurs, an internal power-fail signal is generated which forces the resets to an active state. When V CC returns to an in-tolerance condition, the reset signals are kept in the active state for a minimum of 250 ms to allow the power supply and processor to stabilize.

Drawings Section PBRST TD TOL GND V CC ST RST RST 1 2 3 4 8 7 6 5 DS1832 2 of 7 The second function the DS1832 performs is pushbutton reset control. The DS1832 debounces the pushbutton input and guarantees an active reset pulse width of 250 ms minimum. The third function is a watchdog timer. The DS1832 has an internal timer that forces the reset signals to the active state if the strobe input is not driven low prior to timeout. The watchdog timer function can be set to operate on timeout settings of approximately 150 ms, 600 ms, or 1.2 seconds. OPERATION - POWER MONITOR The DS1832 detects out-of-tolerance power supply conditions and warns a processor-based system of impending power failure. When V CC falls below a preset level as defined by TOL, the V CC comparator outputs the signals RST and RST. When TOL is connected to ground, the RST and RST signals become active as V CC falls below 2.98 volts. When TOL is connected to V CC , the RST and RST signals become active as V CC falls below 2.64 volts. The RST and RST are excellent control signals for a microprocessor, as processing is stopped at the last possible moments of valid V CC . On power-up, RST and RST are kept active for a minimum of 250 ms to allow the power supply and processor to stabilize. OPERATION - PUSHBUTTON RESET The DS1832 provides an input pin for direct connection to a pushbutton reset (see Figure 2). The pushbutton reset input requires an active low signal. Internally, this input is debounced and timed such that RST and RST signals of at least 250 ms minimum are generated. The 250 ms delay commences as the pushbutton reset input is released from the low level. OPERATION - WATCHDOG TIMER The watchdog timer function forces RST and RST signals active when the ST input is not clocked within the predetermined time period. The timeout period is determined by the condition of the TD pin. If TD is connected to ground the minimum watchdog timeout would be 62.5 ms, TD floating would yield a minimum timeout of 250 ms, and TD connected to V CC would provide a timeout of 500 ms minimum. Timeout of the watchdog starts when RST and RST become inactive. If a high-to-low transition occurs on the ST input pin prior to timeout, the watchdog timer is reset and begins to timeout again. If the watchdog timer is allowed to timeout, then the RST and RST signals are driven active for a minimum of 250 ms. The ST input can be derived from many microprocessor outputs. The most typical signals used are the microprocessor address signals, data signals or control signals. When the microprocessor functions normally, these signals would, as a matter of routine, cause the watchdog to be reset prior to timeout. To guarantee that the watchdog timer does not timeout, a high-to-low transition must occur at or less than the minimum times shown in Table 1. A typical circuit example is shown in Figure 4. The DS1832 watchdog function cannot be disabled. The watchdog strobe input must be strobed to avoid a watchdog timeout and reset.
