Abstract: A lens array block comprises a plurality of lens barrels joined to one another form a three-dimensional unitary structure. Each lens barrel comprises a stepped cylindrical chamber having a through hole with an internal profile having first and second steps that are spaced apart through the height of the through hole, the second step being radially inward of the first step. An image capturing unit comprising the lens block array, and methods of fabrication and assembly are also described.

Abstract: The present invention provides a method of making an image capture unit, which includes the steps of: providing an image sensor; attaching a plate on the image sensor; providing at least one cavity on the plate aligned with the image sensor; mounting lenses in the cavity of the plate, and attaching a cover on the plate to shield a margin region of each of the lenses.

Abstract: The invention relates to an angular measurement device comprising a variable reluctance magnetic circuit comprising a fixed portion (3) associated with a coil (2) and at least a moving element (4) attached to a part (5) rotating in front of the fixed portion, the angular position of which is to be detected, comprising: means (I) for integrating the voltage across the coil, means for measuring the instantaneous value of the integrated voltage (15), means for comparing this measure to a calibrating curve of the integrated voltage versus the angle.
