  • Patent number: 11355624
    Abstract: Embodiments are directed to electrically confined ballistic devices, circuits, and networks. One such device includes a heterostructure that has a first semiconductor layer, a second semiconductor layer, and a two-dimensional electrode gas (2DEG) layer between the first and second semiconductor layers. The device further includes an input electrode electrically coupled to the 2DEG layer and an output electrode electrically coupled to the 2DEG layer. A first confinement electrode is positioned on the heterostructure.

  • Patent number: 11290106
    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.

  • Publication number: 20210103631
    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.

  • Patent number: 10753904

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 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.
