The battery (202) includes a thermistor (230), a voltage identifying element (240), a switch (244), a memory device (232), and a battery data contact (228), connected to a data port of the memory device (232) and the voltage identifying element (240). The voltage identifying element (240) determines a voltage that controls the switch (244). When the switch (244) is enabled, the thermistor (230), connected to a battery clock contact (224), is active and a microprocessor (102) on the battery charger (278) reads the value of the thermistor (230) via an analog-to-digital converter. When the switch (244) is disabled, the thermistor (230) is switched out and the battery clock contact (224) is used to clock the memory device (232). The battery charger (278) has a data contact (226) for receiving the battery data contact (228) and a clock contact (222) for receiving the battery clock contact (224). The battery charger (278) further includes at least two switches (204, 206), and the microprocessor (102) is programmed to selectively operate the switches (204, 206).

    摘要: A wireless communication device (50) can include a radio frequency transceiver (52), an audio drive circuit (58) coupled to the transceiver, a speaker (10) having a voice coil (16) coupled to the audio drive circuit, and an antenna feed or radiating circuit (20) such as an RFID or NFID circuit coupled to the voice coil for at least radiating or receiving an electromagnetic signal via the voice coil. Such radiating circuits can be coupled to the voice coil using a band pass circuit designed to substantially prevent a radiating signal from the radiating circuit from interfering with audio drive circuit driving the speaker. The wireless communication device can further include an antenna (54) coupled to the radio frequency transceiver. Note, this arrangement can be designed to avoid problems involving electrostatic discharge sensitivity, electromagnetic interference coupling between the antenna and the voice coil, total radiated power, and specific absorption rate.
