Patent number: 6449313Abstract: A fixed codebook response is able to better characterize an input signal of a vocoder because the entries of the fixed codebook are tailored to the input signal being processed. A uniformly distributed random noise signal is stored in a transmitting vocoder. During encoding by the transmitting vocoder, the noise signal is shaped by a weighing filter and a pitch sharpening filter, which are condition controlled by the linear predictive coding, pitch and pitch gain characteristics of the input signal being encoded. The shaped noise signal is passed though a thresholding filter to arrive at a pulse sequence having a given sparcity. The fixed codebook response is chosen as that portion of the pulse sequence which best matches a residual signal of the input signal. The indexed location of that portion along the pulse sequence is designated as the fixed codebook bits which are included within the bit frame. The identical random noise signal is stored in a receiving vocoder.Type: GrantFiled: April 28, 1999Date of Patent: September 10, 2002Assignee: Lucent Technologies Inc.Inventors: Engin Erzin, Michael C.

Patent number: 6449625Abstract: A method and system for storing data in data blocks of predetermined size in an electronic memory (e.g. FLASH memory), particularly data such as updatable record of database transactions. The FLASH operates logically as two stacks where data is pushed into either end of the memory in alternating cycles. Between each push or write cycle, a garbage collection cycle is performed whereby only the most recent transaction performed on any particular record is preserved at one end of the stack, while the rest of the stack is made available for new data. When database being monitored is written to permanent memory, the entire FLASH is again made available for new data. If the database is periodically backed up to permanent memory, it can be restored to RAM by reducing the copy from the permanent memory and modifying it according to the record of database transactions in the electronic memory.Type: GrantFiled: April 20, 1999Date of Patent: September 10, 2002Assignee: Lucent Technologies Inc.Inventor: Jay Wang
