Title: A method of scrambling a signal
Inventor: KUDUMAKIS PANOS
IPC: G10L25/51
Filed: 2001-02-08
Granted: 2004-03-01
Abstract: A method of scrambling a compressed audio and/or picture signal to provide a scrambled signal for distribution, the information content being recoverable from the scrambled signal using descrambling means (10) under the control of authorized recipients of the scrambled signal, is described. The method consists of or includes: (a) encoding the information content using a wavelet filterbank having a tree structure, (b) distributing the scrambled signal to authorized recipients, and (c) decoding the information content using the corresponding inverse wavelet filterbank. The wavelet filter used, the wavelet filterbank tree structure, the number of decomposition stages in the tree structure and/or the time for which a given filter or tree structure or number of decomposition stages is used can be changed in an apparently random fashion to improve security whilst keeping the scrambled signal recognizable. Progressively increasing distortion with time is also described.

Title: Power management and control
Inventor: OBER ROBERT E
IPC: G06F1/32
Filed: 2001-02-16
Granted: 2002-05-21
Abstract: A power management architecture for a microcontroller. The power management architecture includes a power management state machine (130) for controlling the power mode of the central processing unit (CPU) and each of the subsystems within the microcontroller. The power management state machine (130) includes a software configurable register (SFR) (62) to enable the state machine to be configured for device and application specific applications. Each of the microcontroller subsystems is connected to the system by way of a configurable peripheral interface (FPI) (24). Each FPI includes a software configuration register (SFR) which can be configured by an operating system or application program. The SFR for the various FPIs enables the response to each of the power modes of each microcontroller subsystem to be pre-configured; thus enabling each subsystem to be independently controlled of the power management state machine (130) in order to optimize the power management of the various subsystems. Each of the FPI interfaces as well as the power management state SFR are connected to an FPI bus (24) which interconnects the FPI interfaces with the central processing unit (CPU) (22) and power management state machine SFR. The FPI bus (24) enables reads and writes of the power management state machines SFR and peripheral interface SFRs. Such a configuration allows subsystems to be added or deleted without changing the basic architecture of the power management system, thus forming a modular power management architecture which reduces the cost and complexity designing and developing the microcontrollers.

IPC: H03K17/041
Filed: 2002-03-05
Granted: 2004-03-01
Abstract: A comparator comprises a cross-coupled regenerative latch, a circuit connected to the cross-coupled regenerative latch and a clocking circuit. The cross-coupled regenerative latch regenerates, during a latching mode, a signal which is indicative of a difference between two input signals. The circuit connected to the cross-coupled regenerative latch operates as a voltage follower during an acquisition mode and as a cascode amplifier stage during the latching mode. The clocking circuit switches the comparator from the acquisition mode to the latching mode and vice versa. The comparator eliminates the extraneous loading from the positive feedback when the regeneration takes place, so that a very fast regeneration time constant is obtained.

Title: Method and apparatus for multi-path elimination in a wireless communication system
Inventor: JALALI AHMAD
IPC: H04B7/08
Filed: 2002-08-30
Granted: 2003-10-01
Abstract: Method and apparatus for pre-coding in a communication system are disclosed. In a communication system, an origination station transmits a non pre-coded pilot signal and a pre-coded data signal. A destination station estimates a metric characterizing a communication channel using the non pre-coded pilot signal. The metric is then used to pre-code the data signal to be transmitted. The destination station may also use the estimated metric for demodulation of the pre-coded data. However, since the pilot signal is not pre-coded, the metric for the desired multi-path of the pilot channel differs from that of the pre-coded data channel, which may reduce the demodulation performance. To improve the channel estimation for data demodulation, the origination station may additionally transmit a dedicated pilot signal that is pre-coded in the same manner as the data signal destined to a specific user.
