Abstract: A pixel circuit is provided for use in an image sensor. The pixel circuit includes a photosensitive element configured to generate a current signal in response to brightness of light impinging on the photosensitive element, and a converter configured to receive the current signal from the photosensitive element and generate a voltage signal based on the received current signal. The pixel circuit also includes a capacitor electrically coupled to the converter in series and configured to receive the voltage signal from the converter, and an amplifier electrically coupled, at an input, to the capacitor in series and configured to generate, at an output, an amplified signal based on an output signal from the capacitor, wherein there is no feedback between the output and the input of the amplifier. Further, the pixel circuit includes a reset device configured to reset the amplifier in response to a trigger signal being generated.

Abstract: The method allows communications means to be listed, for end-to-end broadcasting of information other than that required for managing multimedia sessions. After a selection (52) of communications channels through an infrastructure for managing multimedia sessions, the method provides via the application level, the establishment of a communication specifically using the selected communications channel(s). Purely descriptive/explanatory fields of characteristics of a session may be selected at an application level and used for conveying additional information in addition to the signaling protocol. It is thus possible to change the conditions for consuming/using the multimedia contents or the established flux. Instantaneity of the services and service use conditions may be obtained by requesting for example renegotiation in real time of a service when the conditions of use are modified (iconification of a TV/Video streaming flux in order to reduce the bandwidth used).

Abstract: Managing multimedia sessions including surveying anomalies representing illicit uses of a determined signalling protocol, determining reactions in relation to the identified anomaly, collecting all requests exchanged between a client terminal and a proxy server, analysing collected requests for detection of anomalies, through the use of a plurality of indicators each associated with one of the identified anomalies, and in the event of the detection of at least one anomaly, triggering by the proxy server of a reaction corresponding to the detected anomaly, the reaction including real-time action during the communication concerned by the message containing the anomaly. The method therefore allows the real-time detection and filtering of hidden channels utilised in a signalling protocol such as SIP.

Abstract: A system for towing skiers up shallow slopes, comprising a continuously moving rope with a towing run resting on and sliding along the surface of the snow, and a return run held in a raised position by line towers. A safety device stops the system should a skier fail to let go of the towing run at the right time in the arrival area.
