Abstract: A method for rectifying a polymer film including the steps of: a) providing a first substrate including a front surface, the front surface having a surface energy less than approximately 22 mJ/m2, b) spreading a thermoplastic polymer on the front surface leading to the formation of a polymer film and at least one dewetted zone of the front surface, c) providing a second substrate including a non-stick surface, d) bonding the polymer film and the non-stick surface leading to the formation of a bonding interface having an adhesion energy lower than the adhesion energy between the polymer film and the front surface, e) applying a creep treatment so that the at least one dewetted zone of the front surface is covered by creep of the polymer film, and f) disassembly at the bonding interface so as to obtain the front surface completely covered by the rectified polymer film.

Abstract: Example embodiments provide a color filter pattern for a plenoptic sensor. In some embodiments, the plenoptic sensor is a nona-pixel sensor comprising a plurality of microlenses and a respective 3×3 array of color filter pixels under each microlens. The filter pixels have three different colors, and the colors of the color filter pixels are arranged such that each of the sub-aperture images generated from the plenoptic image has an extended Bayer pattern, and such that the pixels of a refocused image generated by adding the sub-aperture images with a disparity value of zero or one receive contributions from three pixels of the first color, three pixels of the second color, and three pixels of the third color.

Abstract: The invention relates to a method for controlling the movement, through a space, of an effector via a brain-computer interface, comprising:
a) acquiring electrophysiological signals produced in the cortex of an individual, at a measurement time;
b) processing the electrophysiological signals, to form input data;
c) processing the input data, by means of a predictive model implemented by the brain-computer interface, to define an effector movement (xps) at the measurement time;
d) determining a corrected effector movement (xcs+1−xcs), based on the movement (xps) defined by the predictive model in step c);
e) moving the effector through the space, by means of the brain-computer interface, based on the corrected movement resulting from step d);
