The FCC ID for this device is RNV0009919150, Confirmation number EA817616. The FCC registration number of our laboratory is 496406, FRN 0005-8509-95. The technical contact for Technical Concepts on this device is Mr. George Jost, Chief Engineer, and for our laboratory is the undersigned. Test data was taken from this device in November and December, 2003. The location of the 10 meter OATS used is 7017 Miller Road, Wonder Lake, Illinois. The location of the 3 and 5 meter indoor site used is 21234 West Commercial Drive, Mundelein, Illinois. The equipment under test consists of two portions, the Autoflush transmitter system, a battery operated (4 AA cell) wireless transmitter that operates at 318 Mhz fixed frequency controlled by a surface acoustic wave resonator and the receiver system, a companion device that is comprised of an integrated superhetrodyne receiver system powered by 4 C cells. The device is used in the bathrooms of hotels, office buildings, restaurants and other places used by the general public. The transmitter generates a signal based on movement detected by an infrared sensor and converts that indication into an amplitude modulated and 24 bit encoded signal that may be transmitted to the receiver up to about 4 feet away. The receiver may detect such a transmission and if it is a match to an encrypted code, will activate a flushing mechanism on a commode. The flushing system is comprised of a motorized apparatus that is installed inside the commode. The transmitter is normally located behind the patron on a wall of the enclosure. Description of Block Diagram The block diagram is shown in the embedded PDF file “Technical Concepts Wireless Transmitter Block Diagram”. You may bring this file up by double clicking on this icon. bat Docu The major subsystems comprising the transmitter are 1) 6 volt power pack, BT1, 2) 3.6 volt regulator, U1, 3) Precision voltage detector, U5, 4) Infrared receiver preamplifier, U2A-B, 5) Infrared Receiver, DT1, 6) Infrared Transmitter, D3, 7) Indicator LED lamps, D6 and D7, 8) Master Controller, U3, 9) Message Encoder, U4 and 10) RF power oscillator, Q7. The overall purpose of the transmitter system is to sense the present of a person about 4 feet away from the detector, and, if present, wait until the person leaves the area and then transmits an encoded and frequency selective RF signal to a receiver which performs a motorized flushing function. Midwest EMI Associates Submittal of Certification to Federal Communications Commission Saturday, January 27, 2004 Page 2 of 2 The controller sequences the activities of this function and it is an OTP proprietary device. The voltage from the power pack will vary as it ages and the purpose of the regulator is to keep the voltage fixed at 3.6 volts until the battery pack is exhausted. When in the normal condition, a green indicator light on the front panel signifies the sensor is active and working normally. The voltage detector function is to sense the point of exhaustion of the battery and alert the controller to that situation. When the battery is low (<5.0V), the controller will signify that by turning on a yellow indicator until the situation is remedied by replacing the batteries. In the low battery condition the RF circuit will not deviate from its normal frequency but the RF power will drop until the batteries are dead. The details of the operation of the voltage detector, encoder, and controller are supplied in the following PDF files that you may access by clicking the icons. bat Docubat Docubat Docubat Docu When the presence of a person is detected, the reflected energy from the IR transmitter to the IR receiver will be high and the controller software detects this but will not activate the RF encoded signal. The controller periodically senses this condition by sending a low or “0” signal to the transmitter LED, D3 and then gates the IR receiver to detect the return pulse by the action of Q1. The purpose of the VR1 and VR2 rheostats is to properly set the gain and pulse shaping of the IR receiver for presentation to the controller IC. When the subsequent absence of a person is detected, the reflected energy from the IR transmitter to the IR receiver will be low and the controller software will send a low or “0” state to the message encoder via U3 pin 17. The action of a low to the transistor gate, Q6, will cause it to conduct battery current to the encoder IC, U4. Since previous to this no energy was supplied to the encoder, the encoder cannot function and the RF circuit is held to an OFF or ultra low power mode and no RF energy is generated to the antenna. The action of the encoder when activated is to send out a 24 bit amplitude modulated signal which biases both the SAW resonator, Y1, and the RF transistor circuit, Q7. The resistor R24 times the release of the encoded 24 bit message to the RF transmitter and its value is fixed. This provides a coherent rate that may be “locked onto” by the receiver. The encoded message includes a silence period, a preamble period and the 24 bit code. In the RF chain, the purpose of C29 and L2 is to reduce harmonics and pass the 318 MHz fundamental frequency generated by the RF transistor. In practice the transmitter and receiver may be operated for months without the necessity of a battery change. We hope this description is useful and thank you for your review. Sincerely, George A.

The receiver may detect such a transmission and if it is a match to an encrypted code, will activate a flushing mechanism on a commode. The flushing system is comprised of a motorized apparatus that is installed inside the commode. The transmitter is normally located behind the patron on a wall of the enclosure. A block diagram is included in the submittal. The sponsor group and Midwest EMI Associates have determined the certification standard for the EUT should be Part 15.231. In use the device complies with all relevant portions of 15.231 section (a) that allows 6166 uV/m at 318 Mhz or 75.8 dBuV/m for the fundamental and 55.8 dBuV/m for any harmonics. The device complies with 15.231 Items 1, 2, and 3 while item 4 is not relevant to this application. The device complies with section (b) and was tested in accordance with Items 1, 2 and 3 exclusively in PEAK MODE while computations are shown here for the relaxations in accordance with Item 4 and sections (c) and (e), Item (d) is not relevant. Calculation of Item (c) of 15.231 (Occupied Bandwidth): The fundamental of the transmitter was measured on the 3 meter indoor site and is shown here: Midwest EMI Associates Submittal of Certification to Federal Communications Commission Saturday, December 06, 2003 Page 2 of 5 The 20 dB down occupied bandwidth is 357 Khz and measured as a percent is .112% meeting the FCC requirement of .25% (15.231 (c)). [This and any other data taken on the 3 meter site used a Tek 2712 with EMC option SN B022981 calibrated on 27 Aug 03. The antenna used is a linearly polarized Antenna Research LPB 2520 SN 1151 calibrated on 27 Oct 03. A 20 dB calibrated preamp, Minicircuits ZKL-2R7 SN D111502, 3 dB matching pad and 61 feet of RG214 cable is also utilized that has been calibrated using a Tektronix TR503 SN B010531 calibrated on 25 Aug 03 and Tektronix 495P analyzer SN B020147 calibrated on 26 Aug 03. The number of points of calibration for this antenna is 2400]. Calculation of Relaxation (15.231 (b) (2)) The FCC allows a quasi peak or average detector to be used for measurement of emissions. In this case, Midwest EMI Associates measures the peak level and calculates the average based on the worst case emissions profile of the device. The baseband emissions profile was measured using a Tektronix TDS 420 oscilloscope [SN B021212 calibrated 25 Aug 03] on a point driving the RF section of the transmitter, pin 5 of the encoder chip, HTPP20 shown on the transmitter schematic. The encoder amplitude modulates the RF carrier with a coded block of which 24 bits is the address code and 23 clocks is the synchronized pilot. [Please see the file “Holtek HT6P20X Encoder.pdf for details]. A one bit was measured with a 640 uS on time in a 1.06 mS period while a zero bit was measured with a 290 uS on time in a 1.06 ms period. Midwest EMI Associates Submittal of Certification to Federal Communications Commission Saturday, December 06, 2003 Page 3 of 5 Calculation assuming all “one” periods results in a relaxation of 4.38 dB. In addition to this the maximum possible rate at which the encoder may generate a code is with a transmission period of 30.6 mS and a silence period of 8.16 ms. When this is calculated an additional relaxation of 2.05 dB is realized for a total computed relaxation of 6.43 dB. [Measured data taken from the oscilloscope is in hard copy form and can be faxed to the FCC on request] Schematic of Transmitter The schematic of the transmitter is shown in the PDF file “Transmitter Schematic”. The sponsor group has supplied a writeup, block diagram, parts descriptions and layout. Schematic of Receiver The schematic of the receiver is shown in the PDF file “Receiver Schematic”. The sponsor group has supplied a writeup, block diagram, parts description and layout. Temperature Testing This device is only used at room temperature conditions and not specified for use under any extreme ambient conditions. The sponsor group does not specify an operating temperature range. Ambient TV and FM Channels Channels that are ambient in the vicinity of Wonder Lake or Mundelein, Illinois are Chicago channels 2, 5, 7, 9, 11, 20, 26, 28, 32, 34, 38, 44, 50, 60, 66; Milwaukee channels 4, 6, 10, 12, 18, 36, 58; Rockford channels 13, 17, 23, 39; and Madison channels 3, 15, and 21.

The FCC ID for this device is RNV0009919150, Confirmation number EA817616. The FCC registration number of our laboratory is 496406, FRN 0005-8509-95. The technical contact for Technical Concepts on this device is Mr. George Jost, Chief Engineer, and for our laboratory is the undersigned. Test data was taken from this device in December through February, 2004. The location of the 10 meter OATS used is 7017 Miller Road, Wonder Lake, Illinois. The location of the 3 and 5 meter indoor site used is 21234 West Commercial Drive, Mundelein, Illinois. The equipment tested consists of two additional companion wireless sensors to the TAF Autoflush wall mounted series previously tested. In this new submission a “C Cell In-Wall Mounted” and “AA Cell Minisensor In-Wall” transmitter and receiver system was characterized. These two systems use almost exactly the same circuitry as previously submitted however in an alternate PCB configuration more compatible with inside the wall mounting. Previous data on the components of this system should be reviewed because the theory of operation and components used are almost identical electrically. The two packages are referred to as the “C cell” transmitter and the “Minisensor” transmitter. The smallest of the two is the Minisensor and either of them fit flush to the wall of the restroom where installed. Additionally a new receiver is supplied with exactly the same electronics with a “new style” flushing mechanism. As in the first submittal the devices are tested as a TR pair. In review, the equipment under test consists of two portions, the Autoflush transmitter system, a battery operated (4 C or AA cell) wireless transmitter that operates at 318 Mhz fixed frequency controlled by a surface acoustic wave resonator and the receiver system, a companion device that is comprised of a integrated superhetrodyne receiver system powered by 4 C cells. The device is used in bathrooms of hotels, office buildings, restaurants and other places used by the general public. The transmitter generates a signal based on movement detected by an infrared sensor and converts that indication into an amplitude modulated and 24 bit encoded signal that may be transmitted to the receiver up to about 4 feet away. The receiver may detect such a transmission and if it is a match to an encrypted code, will activate a flushing mechanism on a commode.
