20110170657 | ANALOG COUNTER AND IMAGING DEVICE INCORPORATING SUCH A COUNTER - An analog counter includes, for at least one step, an input for receiving electric pulses and a means for modifying, by consecutive increments or decrements, a storage voltage for each received electrical pulse, a means for resetting the storage voltage, and a comparator for comparing the storage voltage with a threshold voltage and adapted to generate exceedance information. The counter further includes a control means adapted to control the resetting means in the event of the simultaneous detection of exceedance information from the comparator and of an input pulse. | 07-14-2011 |

20140319322 | MULTIPLE CONVERSION GAIN IMAGE SENSOR - An image sensor including an array of pixels, each having: a storage node coupled to a capacitive sense node by a transfer transistor; and a connection transistor coupling the pixel sense node to an intermediate node of the pixel, wherein each pixel has its intermediate node coupled to a node of application of a reset voltage by a reset transistor, and different pixels have their respective intermediate nodes interconnected by a conductive connection track. | 10-30-2014 |
20150041865 | PIXEL CIRCUIT - A pixel arrangement includes a photodiode, a reset transistor configured to be controlled by a reset signal and coupled to a reset input voltage, a transfer gate transistor configured to transfer charge from the photodiode to a node, wherein the transfer gate transistor is controlled by a transfer gate voltage, and a source follower transistor controlled by the voltage on the node and coupled to a source follower voltage. A capacitor is coupled between the node and an input voltage. During a read operation the input voltage is increased to boost the voltage at the node. The increased input voltage may, for example, be one the reset input voltage, said source follower voltage, said transfer gate voltage and a boosting voltage. | 02-12-2015 |

20130335551 | DEVICE FOR INSPECTING A STEAM GENERATOR - An inspection device for inspecting a steam generator having a first long and flexible video probe intended to be inserted inside the housing of the steam generator and configured to be moveable through a fluid passage orifice defined by a spacer plate and a flow tube, all arranged inside the housing. The first video probe includes at least one ferromagnetic element. The inspection device also includes a second long and flexible probe to be inserted into a flow tube, the second probe including at least one permanent magnet arranged to cooperate with the at least one ferromagnetic element of the first probe so that the first probe can be driven along the exterior surface of a flow tube by the second probe when the second probe is inserted into the flow tube and moved therein, and when the first probe is inserted into the housing of the steam generator and positioned near the exterior surface of the flow tube in which the second probe is inserted. | 12-19-2013 |

20090116605 | Nuclear reactor rod control mechanism control system - The control system comprises an independent removable power module for each coil of a rod control mechanism equipped with three operating coils supplied from a three-phase current source. The power module is connected in series with the corresponding coil and comprises a rectifier circuit with three thyristors controlled in phase angle by a corresponding regulation circuit according to setpoint current values associated with the coil. A monitoring circuit connected to a display interface displays the current flowing in the coil associated with the power module. In the event of a fault, the module and coil involved are easily detected and replaced without requiring shutdown of the whole of the reactor. | 05-07-2009 |
