Ramp-type analogue-digital conversion, with multiple conversions or single conversion, depending on the light level received by a pixel
In a matrix image sensor, a method of reading a pixel of a column allows two modes of analogue-digital conversion of the voltage level provided by the column: a first mode in which are carried out a single analogue-digital conversion in a nominal conversion time window FCONV, of nominal duration dn and a counting which starts with a ramp of nominal duration dn and stops upon the toggling of the output SCMP of the comparator; and a second mode which provides for multiple conversions by comparison with a ramp of reduced duration dr, in the same nominal conversion time window. The selection of the mode of conversion to be applied is based on the observation of the state of the output SCMP of the comparator after a predetermined duration after the instant ti of ramp start: if the output has toggled, the useful level to be converted represents a low light level to which the second mode with multiple conversions will be applied; if the output has not toggled, the useful level to be converted represents a high light level and the first, conventional, mode with single conversion will be applied. The invention makes it possible to improve the signal-to-noise ratio at the output of the sensor, for low light levels, by decreasing the amount of the Gaussian noise due to the circuits of the conversion chain. |

Accessing third-party communication service via a social networking system
A user interface in a social networking system enables users to connect to and interact with each other using a third-party communication service, such as a VoIP or video chat service. A user initiates an interaction with another user in the social networking system, which passes the users' information to the third-party communication service provider to allow it to provide the requested service. The social networking system may pass an encrypted identifier for the users so that the third-party communication service does not have access to the real identities of the social networking system's users. A user of the social networking system may use this process to video conference with users of the third-party communication service, rather than just other users of the social networking system, and vice versa. |

Avoiding internal switching loss in soft switching cascode structure device
In a cascode switching device, avalanche breakdown of a control transistor and loss of soft switching or zero voltage switching in a high voltage normally-on depletion mode transistor having a negative switching threshold voltage and the corresponding losses are avoided by providing additional capacitance in parallel with a parallel connection of drain-source parasitic capacitance of the control transistor and gate-source parasitic capacitance of the high voltage, normally-on transistor to form a capacitive voltage divider with the drain-source parasitic capacitance of the high voltage, normally-on transistor such that the avalanche breakdown voltage of the control transistor cannot be reached. The increased capacitance also assures that the drain source parasitic capacitance of the high voltage, normally-on transistor is fully discharged before internal turn-on can occur. |

Quantum dot channel (QDC) quantum dot gate transistors, memories and other devices
This invention describes a field-effect transistor in which the channel is formed in an array of quantum dots. In one embodiment the quantum dots are cladded with a thin layer serving as an energy barrier. The quantum dot channel (QDC) may consist of one or more layers of cladded dots. These dots are realized on a single or polycrystalline substrate. When QDC FETs are realized on polycrystalline or nanocrystalline thin films they may yield higher mobility than in conventional nano- or microcrystalline thin films. These FETs can be used as thin film transistors (TFTs) in a variety of applications. In another embodiment QDC-FETs are combined with: (a) coupled quantum well SWS channels, (b) quantum dot gate 3-state like FETs, and (c) quantum dot gate nonvolatile memories. |

Nanowire and method of fabricating the same
A method of forming a nanowire includes providing a substrate. The substrate is etched to form at least one fin. Subsequently, a first epitaxial layer is formed on an upper portion of the fin. Later, an undercut is formed on a middle portion the fin. A second epitaxial layer is formed to fill into the undercut. Finally, the fin, the first epitaxial layer and the second epitaxial layer are oxidized to condense the first epitaxial layer and the second epitaxial layer into a germanium-containing nanowire. |
