Abstract: A pulse width modulation device includes a switching transistor for defining modulation phases, a capacitor, and switches arranged to: a) in a first phase, charge the capacitor to a voltage corresponding to the on/off threshold of the switching transistor, and b) in a second phase, connect the capacitor between a terminal for applying a setpoint voltage and the gate of the switching transistor. A constant current source is connected to apply a current in the capacitor tending to bring the gate of the switching transistor toward the on/off threshold.

Abstract: An approach for executing a toolkit action in an IC card includes storing in the IC card one or more identifiers and corresponding toolkit actions, and passing a web page in input to a converter in the IC card. The converter is configured to identify one or more of the identifiers in the html page and related text information associated with the identifiers. The approach includes sending the toolkit actions corresponding to the identifiers identified and the related text information to an application SIM Application Toolkit (SAT) of the IC card, for displaying the text information of the web page as SIM Application Toolkit menu.
Abstract: The present invention relates to systems and methods for inverse telecine or video de-interlacing for picture quality improvement on set-top-box and TV products. The system comprises a film mode detector at the picture or sequence level, a global mixed video and film content detector at the region, picture, or sequence level on top of the detected film content, and a local video content detector at pixel level on top of the detected mixed video and film content. Inverse telecine processing is applied on detected film content fading in with a locally de-interlaced local video content. The invention further provides an apparatus and method for globally detecting mixed video and film content at region, picture, or sequence level. Such apparatus and method comprise a plurality of detectors for robustness and increased detection accuracy.

Abstract: Aspects of the invention are directed towards an apparatus and method for detecting local video pixels in mixed cadence video. The local video detector comprises a comb detector that is adaptive to the contour of moving objects and local contrast, a motion detector that is robust to false motion due to vertical details, and a fader value estimator that provides a video confidence value to a fader that combines film mode and video mode processing results. The coupling of the local video detector to a film mode detector increases the robustness, accuracy, and efficiency of local film/video mode processing as compared to the prior art.

Abstract: The approach is for protecting a solid state memory including a microprocessor. The microprocessor controls the requests for access to the physical blocks of the memory and transfers one or more requested files from a requesting device only subsequently to a comparison of a predetermined sequence of requests for access to the physical blocks. The predetermined sequence of requests for access to physical blocks corresponds to a predetermined sequence of requests for access to file(s) of the memory that can be selected by the device. If the sequence of requests for access does not occur, the microprocessor does not transfer the data requested or transfers them in a non readable format, for example in cryptographic form.
Abstract: Methods and systems are described for displaying video data after a hot plug event during a start-up dead period. In particular, approaches for receiving data, determining whether link training can be performed and, if not, self-configuring a receiver to display the information in a proper format even during the dead period.

Abstract: A nonvolatile memory device includes a discharge circuit configured to selectively connect circuit nodes to discharge terminals through corresponding discharge paths, and an accumulation device for accumulating electric charge. A driving circuit is for driving the discharge circuit in such a way to connect at least a part of such circuit nodes to the discharge terminals if the value of the external supply voltage falls below a corresponding threshold. A supply circuit is for supplying the driving circuit with an intermediate supply voltage. Each one of the intermediate supply voltages is the corresponding external supply voltage when the value of the external supply voltage is higher than the corresponding threshold, or it is an internal voltage locally generated by the supply circuit by exploiting the electric charge stored by the accumulation device when the value of the external supply voltage is lower than the corresponding threshold.
