Abstract: A method for producing special supramolecular assemblies of colorants, in particular cyanine dyes, called J aggregates consists in depositing a monolayer of dendrimers on a support and subsequently in deposing cyanines in solution for forming the organized monolayer of J aggregates. The method can be used for producing a secondary light source for injecting light into a waveguide from a light energy received from a primary light source emitting at different wavelength. The secondary source, which consists of the J aggregates incorporating energy acceptors, can also be integrated into an optical device incorporating the waveguide.

Abstract: A photo sensor exhibiting low noise, low smear, low dark current, high dynamic range and global shutter functionality consists either of a pinned (or buried) photodiode or a photo-sensitive charge-coupled device, each with associated transfer gate, a sub-linear element, a shutter transistor, a reset circuit and a read-out circuit. Using two output paths global shutter and high speed operation are possible for the linear and the sub-linear output of the sensor. Because of its compact size, the photo sensor can be employed in one- and two-dimensional image sensors, fabricated with industry-standard CMOS and CCD technologies.

In an embodiment of the present invention, liquid crystal is used as material for the wedges (W1, W2) resulting in inexpensive and easy to handle Wollaston prisms.

Abstract: A controller permits the implementation of at least one fuzzy logic rule. It has a determination circuit of the overall degree of truth of the premisses of the rule and a determination circuit of the value to be supplied at the output. The determination circuit of the overall degree of truth has a plurality of distance determination circuits each supplying a distance value which is equal to zero when a particular condition of the rule is exactly verified, and which is a square-law function of the difference between the input value and the reference value of this condition. A transformation circuit receiving at the input the sum of the distance values for the different conditions delivers a signal representative of the degree of truth of the premisses of the rule.
