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: A device includes a particle propagation channel, a particle deflector, a particle source, and a particle sink. The particle deflector facilitates ballistic transport of particles from a particle inflow portion through a particle flow deflection portion to a particle outflow portion. The particle deflector is arranged at the particle flow deflection portion and is activatable to deflect particles in the flow deflection portion and is configured to selectively prevent the particles from reaching the particle outflow portion. The particle source and particle sink are configured to cause a current path of the particles through the device.

Abstract: A method for sequencing a nucleic acid strand, comprising the steps of: providing a solution containing truncated strands having lengths different from one another terminating with a respective dideoxynucleotide from among ddATP, ddTTP, ddGTP, and ddCTP; functionalizing first masses by a donor molecule and second masses by an acceptor molecule such as to generate a light emission when they come into mutual contact; coupling a first mass to a first end of each truncated strand; coupling the second masses to a respective terminal dideoxynucleotide of each strand; applying an AC electrical field having variable frequencies that are such as to generate, on each second mass, a net movement directed towards the first mass; acquiring a plurality of light radiations for each frequency value; and associating each light radiation acquired to a respective dideoxynucleotide and, thus, to a respective nucleotide base.

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: A sample treatment and molecule analysis cartridge is configured to be mounted in a treatment machine vertically. 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.

The first and the second electrode regions comprise at least one first electrode and at least one second electrode, respectively, configured to generate in the interposing region an electric field depending on an electric potential difference applied thereto. In the interposing region, a molecular layer is comprised, which is composed of a plurality of molecules, each being capable of assuming one or more states, in a controllable manner, depending on a sensed electric field. The dielectric region has a spatially variable dielectric profile, to determine a respective spatially variable field profile of the sensed electric field at the molecular layer.
