Abstract: A pixel circuit for a ultra-low power image sensor, including: an integration node, on which a photodiode current is integrated, a comparator arranged to compare a voltage at the integration node with a reference voltage, a n+1 bits digital memory, a writing pulse signal generator arranged to generate a writing pulse signal, on the basis of the comparator output voltage and on the voltage at a memory node, the start of the pulse triggering the writing of the digital word in the n-bits digital memory part. The comparator includes a switch in series with a current source and arranged to be commanded by the voltage at the memory node so that the switch is open at the end of the pulse, so as to drastically limit the consumption of static power of the pixel circuit during the integration phase.

Abstract: An autonomous data logger for acquiring and storing sensor data from a sensor. The data logger includes a harvesting device including a power source module. The harvesting device is embedded in a encapsulating layer and includes a receiving area. A sensing device includes a sensor module for acquiring sensor data and is configured to be received in the receiving area of the harvesting device. The receiving area includes a first coupling element and the sensing device includes a second coupling element. The first and second coupling elements are configured to provide attachment structure and electrical connection structure between the sensing device and the harvesting device such that, when the sensing device is received in the receiving area, the sensing device is fixed to the harvesting device and is powered by the power source module.

Abstract: A micro-optical component for generating an image, including a substrate and a lens. The substrate, includes a first surface and a second surface, wherein the first surface includes an aperture, and the second surface is arranged to be connected to a pixel array. The lens is placed on the first surface so as to cover the aperture. The focal point of the lens belongs to the second surface. The lens includes an obscuration element generating at the lens an obscured area and an unobscured area. The obscuration element is dimensioned to reduce the light transmittance towards the pixels for a fraction of the viewing angles only and at the same time. The obscured area is dimensioned so that the optical resolution of the lines is not smaller than the image resolution given by the size of the pixels.

Abstract: A system is provided in which the spatial values (S1 to Sn) of the physical quantity are represented by measurement pulses (I1 to In), the temporal ordering of which represents the values, which are processed by processing units (U1 to Un) arranged in at least one row and each include an output (SOR1 to SORn). During successive processing cycles, a measurement pulse processed therein can be delivered to form the output signal (SU) of the system. Each processing unit includes an inhibiting unit (BI) for, in other units and during a given processing cycle, inhibiting the passage to the outputs of the other units respective measurement pulses processed therein and hence preventing them from forming the output signal, if the measurement impulses are temporally ordered later in the given processing cycle than the one processed in the unit concerned.

The invention is characterized in that each processing unit (U1 to Un) comprises inhibiting means (BI) for, in other units of the row and during a given processing cycle, inhibiting the passage to the outputs (SOR1 to SORn) of said other units respective measurement pulses processed therein and hence preventing them from forming the output signal (SU), if said measurement impulses are temporally ordered later in the given processing cycle than the one processed in the unit concerned.

Abstract: In this network (R) all the cells have identical construction. Each cell is assigned a code word which defines its function which it is to provide for within the network. With a view to the configuring of the cells (Cx,y), means (1) iteratively cause the translation into each of the cells of a genome formed of a train of the successive code words.The network comprises at least one individualized functional organ (O1, O2, O3, . . . ) composed of a plurality of cells which are all characterized by a first predetermined code (<MHC>) forming part of said code word and formed by a number identifying the organ (O1, O2, O3, . . . ) so that these cells can collectively provide for the functionality of this organ. The cells of the latter are distributed as internal cells defined by a first predetermined value of a status code also forming part of the code word, and as membrane cells defined by a second predetermined value of the second code.
