Abstract: A solid reagent containment unit is formed by a support; a frame body fixed to the support and delimiting internally, together with the support, an analysis volume; a reagent-adhesion structure within the analysis volume; and at least one reagent cavity, which extends within the reagent-adhesion structure. The reagent-adhesion structure is of an adhesion material embossable at temperatures lower by 6-8° C. than its own melting point and has a melting point such as not to interfere with the analysis. The reagent cavity forms a retention wall, laterally surrounding the reagent cavity, and houses dried reagents. The adhesion material is chosen among wax, such as paraffin, a polymer, such as polycaprolactone, a solid fat, such as cocoa butter, and a gel, such as hydrogel or organogel.

Abstract: Various embodiments of the present disclosure provide a power device including at least one first conductive element adapted to generate a magnetic field when traversed by a current, and characterised in that it further comprises a Hall sensor electrically insulated from the first conductive element. The sensor and the first conductive element are mutually arranged so as to detect said magnetic field indicative of the current that traverses the first conductive element.

Abstract: Approximation circuitry utilizes bitwise operations on operands to provide approximate results of operations on the operands. A significant digit detector utilizes bitwise operations on the received operands to identify or detect approximate most significant bits in the operands, and then utilizes these identified most significant bits to generate approximate values for each of the operands. Intermediate registers receive and store the approximate values from the significant digit detector. A combinatorial network, such as a lookup table (LUT), thereafter utilizes the approximate values stored in the intermediate registers to generate an approximate result. The approximate result has a value that is an approximate value of a given operation, such as multiplication or division, on the operands provided to the significant digit detector.

Abstract: An integrated fluidic circuit has a supporting surface that carries a first fluid to be moved at a first functional region; a dielectric structure, defining the supporting surface; and an electrode structure, coupled to the dielectric structure for generating an electric field at the first functional region, such as to modify electrowetting properties of the interface between the first fluid and the supporting surface. The dielectric structure has a first spatially variable dielectric profile at the first functional region, thus determining a corresponding spatially variable profile of the electric field, and, consequently, of the electrowetting properties of the interface between the first fluid and the supporting surface. The integrated fluidic circuit may achieve mixing between the first fluid and a second fluid.
