A wireless communication apparatus capable of providing information requests includes a wireless communication device having a wireless transceiver configured to send and receive communications across a wireless communication network. A hands-free unit can be included and coupled to the wireless communication device. The hands-free unit includes a speaker and a microphone configured to provide audio information to a user and to accept audio information from the user. A position determination system determines a location of the apparatus and provides position data indicative of such location to a server along with the information request. The server can process the information request along with the position information and provide a response to the request to the wireless communication apparatus.

System and method for automatic device synchronization

The battery charging system of the present invention charges the battery of a portable, multiple mode radiotelephone while the radiotelephone is operating. The radiotelephone generates a clock signal having varying on/off times dependent on the radiotelephone's mode. This mode can include an analog cellular mode or a digital cellular mode. The battery charger detects the clock signal's on/off times and changes the average charge current to compensate for one mode requiring a larger charge current.

Battery charger

The battery charging system of the present invention charges the battery (105) of a portable, multiple mode radiotelephone (110) while the radiotelephone is operating. The radiotelephone (110) generates a clock signal having varying on/off times dependent on the radiotelephone's mode. This mode can include an analog cellular mode or a digital cellular mode. The battery charger (100) detects the clock signal's on/off times and changes the average charge current to compensate for one mode requiring a larger charge current. The clock signal is coupled to the charger using the same multiple function connection (160) as the battery's thermistor (150). The charger (100) uses the thermistor (150) to determine when the battery (105) is charged.
