Abstract: Transliteration architectures reduce the number of encoding/decoding steps required to transmit telephony data. The reduction of encoding/decoding steps improves the quality of the transmitted data due to the avoidance of the significant adverse effects on the data from encoding and decoding. The reduction is accomplished using a transliterator device or through bypassing the transliterator device. A universal vocoder is proposed that allows the vocoding element to encode or decode data according to any desired vocoder format. Network routing considerations allow optimal decisions on which vocoder formats to use. Network routing decisions can be made based on vocoder formats used.

Abstract: A system and method for recharging secondary batteries. One embodiment of the present invention comprises a supervisory circuit, a voltage converter, a portable power source, and one or more of a holder and a socket. The holder is adapted to receive a specific type of secondary battery of a portable device. The socket is adapted to mate with a plug of a device-specific charging cord connected to the portable device. Each of the holder and the plug can be associated with a programming resistor that provides a voltage requirement of the secondary battery. When the secondary battery is either placed in the holder or is connected to the socket, the supervisory circuit communicates with the voltage converter to supply the appropriate voltage required to recharge the secondary battery. The voltage converter receives power from the portable power source. The voltage converter can convert the voltage of the portable power source up (i.e., increasing the voltage) or down (i.e.

Abstract: A base station for providing flexible data rate transmission in a telecommunications system. The base station comprises an interface coupled to a signal processor coupled to a transmitter. The interface receives an incoming data stream. The signal processor receives the incoming data stream from the receiver and selects an operating downlink chip rate from at least two chip rates. The signal processor selects a spreading factor and spreads the incoming data stream into a spread data stream with a channelization code. The transmitter, receives the spread data stream from the signal processor and transmits the spread data stream over an air interface.
