Title: Gianluca Colli: Innovator in Optical Sensor Technology

Introduction

Gianluca Colli is a notable inventor based in Sannazzaro de'Burgondi, Italy. He has made significant contributions to the field of optical sensor technology, holding a total of 3 patents. His work reflects a deep understanding of image processing systems and current comparator circuits.

Latest Patents

One of Gianluca Colli's latest patents is an adaptive optical sensor. This integrated image processing system features an array of cells arranged in rows and columns. Each cell corresponds to a pixel of an image and includes a photosensitive element for detecting the luminous intensity of its respective pixel and for generating a value. A first switch controls the transfer of the value from a respective photosensitive element to the corresponding capacitor, which stores the value. A second switch couples each of the cells in parallel to a common line. A control circuit receives the values from each cell on the common line and generates a signal for regulating the switching time interval of the first switch.

Another significant patent is a current comparator with intrinsic limitation of absorption to the lowest. This invention provides a method and a respective circuit arrangement capable of markedly limiting the absorption of current by a current comparator circuit. The invention consists of limiting the absorption of current through the branch of the comparator circuit, along which is forced the highest current to the value of the lowest current, which is in turn forced through the other branch of the comparator circuit. This condition is achieved without interfering with other characteristics of switching speed and sensitivity of the comparator circuit.
