QBKETD-2740CowTek HealthWatch system

Part I: The CowTek HealthWatch System Overview The CowTek HealthWatch system uses an electronic ETD BOLUS (Elevated Temperature Detection bolus) to monitor cattle for infections or illnesses which cause loss in weight gain or milk production. The ETD BOLUS consists of a weighted capsule which rests in the animal’s rumen and incorporates temperature monitoring and recording circuitry together with a radio-frequency transmitter to report changes in internal temperature which may indicate illness or infection. In addition to simple long- term health monitoring, the HealthWatch system also offers special veterinary monitoring and fertility detection modes. Note: fertility detection is presently in development and is not offered as a reliable indicator. This feature is included, however, because it is being used in laboratory settings for further research. Also, because cattle are less thermally stable than some species and because their normal internal temperatures can vary with seasonal, climatic and regional conditions, the ETD BOLUS accepts threshold reporting levels which can be set either using the Desktop Exciter prior to implanting the bolus. Hardware Components: To manage and monitor report transmissions from the boluses and to control operational modes, in addition to the temperature boluses, the HealthWatch system includes three types of external device: a Desktop Exciter to initialize boluses and a Field Receiver to monitor cattle over a wide area. Temperature Bolus The ETD BOLUS is an active, battery-powered temperature monitoring device which records and tracks temperature changes. The bolus is designed to ignore minor temperature fluxuations caused by diet or exertion while reporting prolonged elevated temperatures which are indications of illnesses or infections which demand attention and treatment. Figure 1: The CowTek HealthWatch Temperature Bolus The ETD BOLUS is sealed in an inert polypropylene capsule and weighted to prevent the bolus from being expelled from the rumen or from being passed through the digestive system. Powered by a sealed lithium battery, the ETD BOLUS has a functional lifespan – without attention – of approximately five years. Because a cow’s normal temperature can vary according to the temperature of their environment, the ETD BOLUS monitors and calculates a ‘normal reference’ temperature for each animal, adjusting this reference temperature according to seasonal and climatic changes. In addition to long-term health monitoring, the ETD BOLUS can also be used for veterinarian monitoring to report reactions to injections, implants or other treatments and can be used for ovulation monitoring (in development) to report when an animal is ready for artificial (or natural) insemination following the use of fertility stimulants. NOTICE TO THE USER Any changes or modifications not expressly approved by CowTek, Inc for compliance could void your authority to use the equipment. FCC WARNING This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Desktop Exciter The Desktop Exciter is used to ‘turn on’ a pill before it is given to the cow or bull. Because of FCC requirements for active transmitter devices and to ensure maximum battery life (estimated ~5 years), the HeathWatch temperature pills are shipped in a QUIET or OFF mode and must be initialized before use. The Desktop Exciter – see Figure 2 – has a recessed grove on the top shaped to the orientation of the pill; three mode buttons labeled WAKEUP, FERTILITY and VETERINARY and three threshold buttons labeled WINTER, NORMAL and SUMMER. In addition there are two LEDs – one RED and one GREEN – which show operation and status; one serial port (DB9, RS232, not shown); and a power connection (not shown). Figure 2: The Desktop Exciter Components The Desktop Exciter includes a 12-volt power supply (120VAC to12VDC) and a serial cable for connections to a desktop computer. Field Receiver The Field Receiver consists of a control box and a pole-mounted antenna and is used to monitor and record messages transmitted by HealthWatch temperature pills in cattle over a wide area. The Field Receiver control panel does not provide switches to select operational modes or change temperature thresholds. Figure 4: The Field Receiver Control and Antenna The number and locations of Field Receivers necessary are determined by the area to be covered including such factors as the number of cattle, and the size and location of the pens or other enclosures being monitored. The Field Receiver control box has one LED pair (RED/GREEN) to report status information (see LED Indicators) and a set of four serial connectors, one power connection and one RF connector (see Ports and Connections). Note: the two DB9 connectors on the front of the Receiver control box (one male, one female) and the two DB9 connectors on the bottom (one male, one female) are all connected as a single serial port. The two types and two positions simply provide convenient connections for either a handheld (PDA) device or a desktop or laptop computer. Components The Field Receiver includes a 12-volt power supply (120VAC to 12VDC) and a coaxial cable (control panel to antenna unit). Optional components include: • PDA (handheld) to DB9 serial cable – required for handheld versions of HealthWatch Monitor and Commander programs. • DB9 Serial cable (M/F) – required for desktop/laptop connection to run HealthWatch Monitor and Commander programs. LED Indicators The Field Receiver has one LED pair (one red, one green) on the control box. Functionally, the LEDs are used for error and status reporting as: Error / Status Reporting LED Display Meaning Duration GREEN slow blink reports waiting for download until data is dumped to handheld / desktop or u…

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 October 15, 2002 RE: FCC ID: QBK ETD-2740 Attention: Jeffrey Lenk, Nicole Golden I have a few comments on this Application. 1 The label information does not specify what the label is made of and how it is attached to the device. Please provide this information. xxx 2 Please note that unless the ckt boards are ‘potted’ or otherwise prevented for being accessed or viewed by the user at the time of purchase, the internal photos cannot be held confidential. The board will be provided as not confidential unless it can be shown how this board will be potted and prevented from being exposed to view. xxx 3 You show the final transmitter section but have not provided any input as to the modulation circuitry used in the device. Please provide schematics of the entire transmitter device including the modulation circuitry. xxx 4 Please provide a theory of operation or a technical description of how the device operates. This is necessary to determine if the device falls into the requested part 15 section. xxx 5 Your manual states, “Any changes or modifications not expressly approved by CowTek, Inc for compliance could void your authority to modify the equipment.” This is a misleading statement and does not present the intent of the FCC non-modification statement of 15.21. The statement is to notify users that unauthorized modification of the device may void the authority to use the device, not that it voids the authority to modify the equipment. Please correct the statement to reflect the intent of the FCC non-modification statement. xxx 6 The report does not indicate if the device was tested in the three orthogonal axis. Please provide data or an explanation as to testing all three orthogonal planes, xxx 7 The documentation does not appear to specify that the device meets the 15.231e rules pertaining to automatic limiting of transmission. 15.231 states, “In addition, devices operated under the provisions of this paragraph shall be provided with a means for automatically limiting operation so that the duration of each transmission shall not be greater than one second and the silent period between transmissions shall be at least 30 times the duration of the transmission but in no case less than 10 seconds.” Please provide evidence that the device meets this criteria.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 October 18, 2002 RE: FCC ID: QBK ETD-2740 Attention: Jeffrey Lenk, Nicole Golden I have a few comments on this Application. 1 See item 7 form ATCB comments of 10-15-02. The theory of operation states that data is sent to the transmitter, “in a 1-5 second Three pulse (anti-collision) output. Please note that 15.231e states, “In addition, devices operated under the provisions of this paragraph shall be provided with a means for automatically limiting operation so that the duration of each transmission shall not be greater than one second and the silent period between transmissions shall be at least 30 times the duration of the transmission but in no case less than 10 seconds.” The description in the theory of operation would seem to violate this one second limit to transmission as well as disagree with the test criteria in the report.. Please explain. xxx 2 You have not addressed the modification issue of item 5 from the ATCB comments of 10-15- 02. Please address this issue and clarify the intent of the required FCC non-modification statement. xxx Dennis Ward mailto:[email protected] The items indicated above must be submitted before processing can continue on the above referenced application.
