TechInformation_v02-7.doc Page 1 of 2 Brief Technical Information of the Body Scale When user plugged 4 AA cells into the battery compartment, the Body Scale (here after called “the device”) is ready to use. Part A—Regarding to Schematic Diagram “Scale_v08.pdf” The “Bridge_Sensor” outputs voltage (across BS-, BS+) correlated to weight imposed on the device. It passes through an RC network (R7, R8, C1, C21, C22) and ends at pins AI+, AI- of U1. U1 processes the voltage data and display corresponding weight information on the LCD with calibration data stored inside EEPROM U4. In addition, U1 stores weight data along with time information (obtained from RTC chip U3) to U4. U1 will activate the Bluetooth Module by enabling the power supply to the module. This is done by setting pin 4 (CE) of U5 to high voltage level. Pin 5 of U5 will provide a steady 3.3V to the Bluetooth Module. U1 will then send weight, time and other information to the Bluetooth Module via its UART_IN pin. Bluetooth Module will, in return, send information back to U1 via UART_OUT pin of U1. After sending data out via the Bluetooth module (or after being idle for over 5 minutes), the device will enter its standby mode (power to Bluetooth Module disabled, with other measures done in order to keep current consumption low). The device leaves it standby mode by activating the vibration switch S2 when user steps on the device. Part B—Regarding to Schematic Diagram “ISBTM8-3(Class1 Module)_1120.pdf” The Bluetooth Module communicates with U1 (of “Scale_v08.pdf”) via its Baseband IC U4 (along with data stored inside the EEPROM U6). U5, U2, U3, SW1, SW2, SW3 are the major components of the module to handle the RF part of the Bluetooth communication. The module outputs the RF signal via its pin 1 (RF_OUT). Pseudo-random hopping sequence is used over the total 79 channels between 2.402GHz to 2.480GHz. And with a nominal hop rate of 1600 hops/s. The transmit timming is equal to the bluetooth specification v1.1.Details illustration of the circuit can be found in the following block diagram. TechInformation_v02-7.doc Page 2 of 2 SW1-3 shown about are GaAs MMIC SPDT switches to folk one signal path into two. U5 serves two functions here: a) U5modulates digital signal from U4 to RF signal. The RF signal goes through SW3 to SW1 under the control of pins TX, RX. This signal further goes through SW1 to the Power Amplifier of U2. With control pins PL, PH, two different gains can be provided to the Power Amplifier where J is mainly a voltage divider consisting of R2-4. Finally the signal path ends at SW2 which goes to pin 1 (RF_OUT) b)U5 decodes RFsignal received from Pin 1 (RF_OUT). RF signal received firstly goes through SW2 to U3 under the control of pins TX, RX. U3 is a 2.4GHZ SAW filter centered at 2442MHz. The LNA of U2 amplifies the RF signal to SW3. Finally, this signal reaches U5 under the control pins of TX, RX. Part C—Regarding to Schematic Diagram “Antenna.pdf” The antenna of the device is printed on the main PCB and is connected to RF_OUT pin of the Bluetooth Module. This RF_OUT signal feeds into the antenna via a simple LC impedance matching network (L2, L3, C28).
