20110019488 | DOUBLE-GATE FLOATING-BODY MEMORY DEVICE - A memory device is provided comprising a transistor having a floating body positioned between source and drain regions, the floating body being sandwiched between first and second insulated gates each comprising a gate electrode. A control circuit is arranged to program the state of said floating body to have an accumulation or depletion of majority carriers by applying one of first and second voltage levels between the first gate and at least one of the source and drain regions, and to retain the programmed state of said floating body by applying a third voltage level to the second gate. The voltages are switched over a time duration shorter than 100 ns. | 01-27-2011 |

20100308980 | NETWORK ARCHITECTURE FOR WIRELESSLY INTERFACING SENSORS AT ULTRA LOW POWER - A sensing network is described, consisting of a multiplexing reader and one or more sensor pairs, each sensor pair comprising a transponder and a dedicated reader, dedicated to that transponder, each transponder having a sensor. Each sensor pair is able to wirelessly interface and power both capacitive and resistive sensors at a short distance with high efficiency. By providing a dedicated reader for each transponder, each link can be optimized and there is no need for the dedicated reader to distinguish between signals from other transponders. The transponder generates an analog signal directly using a sensor or analog memory value and sends it by modulation to the dedicated reader. So, the dedicated readers do not need to have circuitry to demodulate a digital signal or ID code. The transponder includes the sensors and their electronic circuits and can be optionally remotely powered by the dedicated reader through the wireless link. The expected consumption of the dedicated reader can be lower than 200 μW. | 12-09-2010 |

20110260615 | PROCESS AND DEVICE FOR CONTROLLING A PLURALITY OF LED ASSEMBLIES OF AN AUTOMOTIVE VEHICLE - A process and a device for controlling a plurality of LED assemblies of an automotive vehicle, each LED assembly (Gi) executing a specific lighting/signalling function. The electrical power level (Pi) delivered by the electrical source is modulated according to distinct power levels (Pi) with relation to the function associated with each LED assembly (Gi) and temporary multiplexing is executed in order to successively transmit the distinct power levels (Pi) to the assemblies (Gi) over a multiplexing period (Tmux). Demultiplexing is effected and each distinct electrical power level (Pi) is selectively delivered to the LED assembly (Gi) concerned. | 10-27-2011 |
20110279058 | MODULE TO CONTROL THE SUPPLY TO LED ASSEMBLIES - A device for measurement of characteristic parameters of at least one assembly of at least one light emitting diode (LED) comprising a measurement circuit for each assembly, wherein the measurement circuit has an electrical input which can be connected to the LED, a single measurement output to provide electrical values which are representative of at least two characteristic parameters of the LED, a first circuit configuration, which is designed to provide the measurement output with a value which is representative of a first characteristic parameter, a second circuit configuration, which is designed to provide the measurement output with a value which is representative of a second characteristic parameter and means for switching between the first circuit configuration and the second circuit configuration. | 11-17-2011 |

20120079153 | COMMUNICATION METHOD AND DEVICE FOR A MOTOR VEHICLE - A communication method is implemented in an on-board network between a master station (M) and a plurality of slave stations (S1, S2, S3, S4), of the type of those compatible with the standard Local Interconnect Network (LIN) protocol in which data frames are sent by the slave stations on a serial bus in response to the sending by the master station of identifiers representative of the required content of the frames. All or part of each of the specific data frames attached to the same predetermined identifier is formed sequentially by each of the slave stations. This enables an optimisation of the load on a LIN network, thus enabling use of this economical standard for all “passenger compartment functions”, and in particular for the management of AFS type advanced lighting systems. | 03-29-2012 |

20120025727 | METHOD FOR CONTROLLING LIGHT-EMITTING DIODES - A method and a device for gradually controlling the illuminating light intensity of light-emitting diodes by modulating the width of current pulses of defined duty cycle, using a DC-to-DC voltage converter and a control circuit for switching the supply current of the light-emitting diodes. Prior to switching the power supply of the diodes the DC-to-DC converter is initiated (A), so as to generate voltage pulses of defined duty cycle; the steady state of each pulse is determined (B), so as to generate a voltage pulse (CP) calibrated to a voltage level substantially corresponding to the steady-state level; and then the light-emitting diodes are powered (D) by applying each calibrated pulse to the light-emitting diodes by means of the switchable control circuit. | 02-02-2012 |
