  • Publication number: 20220149823
    Abstract: A novel and useful system and method of generating quantum unitary noise using silicon based quantum dot arrays. Unitary noise is derived from a probability of detecting a particle within a quantum dot array structure comprising position based charge qubits with two time independent basis states |0> and |1>. A two level electron tunneling device such as an interface device, qubit or other quantum structure is used to generate quantum noise. The electron tunneling device includes a reservoir of particles, a quantum dot, and a barrier that is used to control tunneling between the reservoir and the quantum dot. A detector circuit connected to the device outputs a digital stream corresponding to the probability of a particle of being detected. Controlling the bias applied to the barrier controls the probability of detection. Thus, the probability density function (PDF) of the output unitary noise can be controlled to correspond to a desired probability.

  • Publication number: 20220147824
    Abstract: A novel and useful system and method of accelerated learning in neural networks using silicon based quantum dot arrays. Unitary noise is derived from a probability of detecting a particle within a quantum dot array structure comprising position based charge qubits with two time independent basis states |0> and |1>. A two level electron tunneling device such as an interface device, qubit or other quantum structure is used to generate quantum noise. The electron tunneling device includes a reservoir of particles, a quantum dot, and a barrier that is used to control tunneling between the reservoir and the quantum dot. Controlling the bias applied to the barrier controls the probability of detection. Thus, the probability density function (PDF) of the output unitary noise can be controlled to correspond to a desired probability. The quantum unitary noise is injected into one or more layers of an artificial neural network (ANN) to improve the learning and training process.

  • Publication number: 20220138103
    Abstract: A method and apparatus physically partitions clean and dirty cache lines into separate memory partitions, such as one or more banks, so that during low power operation, a cache memory controller reduces power consumption of the cache memory containing the clean only data. The cache memory controller controls refresh operation so that data refresh does not occur for clean data only banks or the refresh rate is reduced for clean data only banks. Partitions that store dirty data can also store clean data, however other partitions are designated for storing only clean data so that the partitions can have their refresh rate reduced or refresh stopped for periods of time. When multiple DRAM dies or packages are employed, the partition can occur on a die or package level as opposed to a bank level within a die.

  • Patent number: 11304608
    Abstract: A method and apparatus for evaluating foot inflammation each uses at least one temperature detection modality to form a first thermogram and a second thermogram of the sole of at least one foot. Each thermogram forms a substantially continuous set of two-dimensional temperature values across the sole of the (at least one) foot. The thermograms have features; namely, the first thermogram has first features and the second thermogram has second features. The method and apparatus thus control a device to apply at least one transformation to the first and second thermograms to align the first features with corresponding second features, and determine, at any thermogram location, if at least one of the thermograms presents one of a plurality of patterns indicative of inflammation. Finally, the method and apparatus each produce output information indicating the result of the determination of whether the thermograms present one of the plurality of patterns.
