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.

The cartridge has a sample inlet opening, a fluidic inlet, and a fluidic outlet. The cartridge houses an extraction chamber extending vertically from the sample inlet opening and connected to the fluidic inlet; a waste chamber extending vertically, alongside the extraction chamber; and a collector extending along the extraction chamber and the waste chamber and having a smaller height than the extraction chamber and the waste chamber. A fluidic circuit connects together the extraction chamber, the waste chamber, the collector, the fluidic inlet, and the fluidic outlet, and is configured to connect the fluidic outlet to vent openings of the extraction chamber, the waste chamber, and the collector, and to connect the bottom end of the extraction chamber to the fluidic inlet, the waste chamber, and the collector.

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.

Abstract: Systems and devices are provided to perform low-power digital filtering of sensor or other data based on bitwise operations. A reference sinusoid is encoded via a plurality of pulse trains, such that each pulse train includes a number of pulses n representing a value of the reference sinusoid out of a maximum possible pulses corresponding to an encoding quantization level. A circular register stores a representation of the encoded sinusoid. A set of multiple logical gate blocks are configured to multiply, via one or more bitwise operations, each of multiple bits of a received input signal with a pulse train corresponding to a value of the encoded sinusoid. A logic circuit coupled to the circular register and the set of multiple logical gate blocks is configured to generate, based on the encoded sinusoid and on the input signal, an output signal indicating an approximate value of the received input signal multiplied by the encoded sinusoid.

Abstract: Embodiments are directed to two-dimensional electron gas (2DEG)-confined 2DEG devices and methods. One such device includes a substrate and a heterostructure on the substrate. The heterostructure includes a first semiconductor layer, a second semiconductor layer, and a 2DEG layer between the first and second semiconductor layers. The device further includes a 2DEG device having a conduction channel in the 2DEG layer. An isolation electrode overlies the heterostructure and at least partially surrounds a periphery of the 2DEG device. The isolation electrode, in use, interrupts the 2DEG layer in response to an applied voltage.
