Title: Improvements relating to dynamic random access memories
Inventor: VELAYUDHAN BIJU
IPC: G11C11/409
Filed: 1996-06-03
Abstract: An output buffer unit for use with a dynamic random access memory includes a first stage (40,41) for generating complementary logic signals.

Title: Intelligent peripheral
Inventor: LOZINSKI ZYGMUNT ANTHONY
IPC: H04Q11/04
Filed: 1997-03-19
Abstract: This invention relates to an intelligent peripheral (IP) for connecting to a telephone network and providing added capabilities to the network. More particularly the invention relates to programmable suppression of call answer supervision by an intelligent peripheral or a voice recognition unit in a telephone network. The method comprises the steps of: the peripheral device receiving a call setup message from a network switch when a call is being initiated. The IP, on receipt of the call setup signal, suppresses the normal answer signal output and instead outputs a progress signal to the network switch. For an ISDN network the progress signal is a Progress Indicator PI=08 signal.

Title: Video teleconferencing system with digital transcoding
Inventor: POLOMSKI MARK
IPC: H04N7/26
Filed: 1996-01-16
Abstract: A video teleconferencing system uses digital transcoding to obtain algorithm transcoding, transmission rate matching, and spatial mixing. The video teleconferencing system comprises a multipoint control unit (MCU) for allowing multiple audiovisual terminals, which send and receive compressed digital data signals, to communicate with each other in a conference. The MCU has a video processing unit (VPU) that performs algorithm transcoding, rate matching, and spatial mixing among the terminals within a conference. The VPU includes a time division multiplex pixel bus and a plurality of processors. Each processor is assignable to an audiovisual terminal in the conference and is coupled to the pixel bus. In a receive mode, each processor receives and decodes compressed video signals from its assigned terminal and puts the decoded signal onto the pixel bus. In a transmit mode, each processor receives from the pixel bus uncompressed video signals from any terminal in the conference. The uncompressed video signals are processed and encoded for transmission to the respective assigned terminal. Video encoding time due to motion displacement search is reduced by passing displacement information from the compressed video signals to the encoder to be used directly or as a seed for further refinements of the motion displacement field.

Title: Software licence management system uses clustered licence servers
Inventor: BARATTI PAOLO
IPC: G06F21/10
Filed: 1999-02-19
Abstract: Software licence management system which provides flexibility in the number of licence servers that participate in a cluster. The licence management system permits the concurrent use of n copies of a software program over a network (e.g. a LAN) comprising a plurality of client workstations 103, each having a copy of a software program installed thereon and requiring an authorisation from one of a plurality S of licence servers 101 each time the software program is used. For high availability, the licence servers 101 employ redundancy, each containing a licence database 401. For security, the licence management system requires that at least the integer majority, M, of the plurality of licence servers is active at any time (e.g. two out of the three servers shown); otherwise, all the servers stop serving licences. The number of licence servers can be changed, but subject to the following limit: where s1 and s2 are respectively the minimum and maximum number of servers in the cluster, M(s1) + M(s2) > s2, with s1<=S and s2>=S.

Title: Improving speech intelligibility in presence of noise
Inventor: MCLOUGHLIN IAN VINCE
IPC: G10L25/24
Filed: 1998-07-01
Abstract: A speech communication system comprises a receiving unit 14 which receives speech data and uses that data to output speech 15. The characteristics of the speech are altered by processing unit 10 based upon the listener's current background noise before the speech is output to enhance its intelligibility to a listener. An analysis unit 12 determines the type and level of the background noise by a microphone 13 and decision unit 11 determines whether the speech currently received would be intelligible to an average listener in the current background noise. If unit 11 determines that the speech would be unintelligible, then processing unit 10 alters the speech before passing it to the output to make the speech more intelligible. Preferably the speech characteristics are altered by altering line spectral pair data representing the speech.
