Abstract: A method includes generating, by a first spiking neuron, an event detection signal indicating a time of detection of an event in a data flow. The event detection signal is transmitted from the first spiking neuron to a second spiking neuron. The second spiking neuron generates a spike delayed, with respect to the time of detection of the event, according to an amplitude of the event. The delayed spike is included in a coded signal.

Abstract: An embodiment method for estimating a missing or incorrect value in a table of values generated by a photosite matrix comprises a definition of a zone of the table comprising the value to be estimated and other values, referred to as neighboring values, and an estimation of the value to be estimated based on the primary neighboring values and the weight associated with these primary neighboring values, wherein a weight of each neighboring value, referred to as primary neighboring value, of the same colorimetric component as that of the missing or incorrect value to be estimated, is determined according to differences between neighboring values disposed on an axis and neighboring values disposed parallel with this axis and positioned in relation to this axis on the same side as the primary neighboring value for which the weight is determined.

Abstract: An exemplary semiconductor memory includes a channel region disposed in a semiconductor body, a gate region overlying the channel region, a first and a second source/drain region disposed in the semiconductor body, where the first source/drain region is spaced from the second source/drain region by the channel region. The exemplary memory further includes a first contact electrically contacting the first source/drain region, a second contact electrically contacting the first source/drain region and spaced from the second contact, and a third contact electrically contacting the second source/drain region. The first and second contacts are configured so that a resistivity of the first source/drain region can be irreversibly increased by application of an electric current between the first and second contacts. The first contact extends over a first width, the third contact extends over a third width, where the first width is smaller than the third width.

Abstract: A 90° hybrid inductive-capacitive coupling stage includes two first stage terminals capable of forming two stage inputs or two stage outputs and two second stage terminals capable of respectively forming two stage outputs or two stage inputs. The coupling stage is advantageously modular having a first stage axis of symmetry and a second stage axis of symmetry orthogonal to each other with neighboring inductive metal tracks being overlaid in at least one crossing region to form both an inductive circuit and a capacitive circuit. The metal tracks are coupled to the first stage terminals and to the second stage terminals such that the two first stage terminals are situated on one side of the first stage axis of symmetry and the two second stage terminals are situated on the other side of the first stage axis of symmetry.

Abstract: A contactless card is powered by an antenna connected to the input of a rectifier. An output of the rectifier is coupled to a processing unit that consumes a first current output from the rectifier. A current regulation circuit is connected to the output of the rectifier. The current regulation circuit operates to absorb a second current from the output of the rectifier such that a sum of the first and second currents is a constant current.

Abstract: An embodiment electronic device comprises at least two antennas for transmitting signals, and at least one transmission path, the transmission path including a first coupling stage including a power divider, variable-gain power amplifiers, and a second coupling stage including a power combiner. Each coupling stage includes two inputs and two outputs, the two inputs of the first coupling stage being configured to receive a power input signal. Each output of the first coupling stage is connected to a different input of the second coupling stage via the variable-gain power amplifiers, and each output of the second coupling stage is connected to a different antenna. A controller is configured to control the gains of the variable-gain power amplifiers according to the characteristics of the power input signal, the signals transmitted by the antennas, and the coupling stages.

Abstract: A method tests a plurality of devices, each device including a test chain having a plurality of positions storing test data. The testing includes comparing test data in a last position of the test chain of each of the devices. The test data in the test chains of the devices is shifted forward by one position. The shifting includes writing test data in the last position of a test chain to a first position in the test chain. The comparing and the shifting are repeated until the test data in the last position of each test chain when the testing is started is shifted back into the last position of the respective test chain. The plurality of devices may have a same structure and a same functionality.
