  • Publication number: 20200042434
    Abstract: Techniques for analysis of verification parameters and reduction of training data are provided. A plurality of test results is received, where each of the plurality of test results specifies a respective one or more parameters and a respective one or more events. A list of parameters used to stimulate computing logic is determined. Additionally, a plurality of relevant parameters is generated, corresponding to parameters in the list of parameters that have at least two distinct values specified in the plurality of test results. A plurality of training cases is generated based on the plurality of test results and the plurality of relevant parameters. Further, a neural network is generated for design verification of the computing logic based on the plurality of relevant parameters. The neural network is trained based on the plurality of training cases.

  • Publication number: 20200042730
    Abstract: A computer system, processor, and method for processing information is disclosed that includes watching logical operations to detect unauthorized attempts to access a register, and taking evasive action in response to detecting unauthorized attempts to access the register. In an embodiment, the register is a hidden, secret, restricted, or undocumented register, and the method further includes, in response to unauthorized attempts to access the secret register, locking the contents of the secret register. The evasive action may include one or more of interrupting the operations of the processor; causing the processor to shut-down, malfunction, lock, self-destruct; no longer providing read or write permission or access to the register; releasing data disguised to look like the real register data while not releasing the real data; and combinations thereof.

  • Patent number: 9974956
    Abstract: Methods, systems, and apparatus for quantifying the quality of a fiducial time marker for a candidate heart beat, quantifying the quality of a candidate heart beat, or determining a time of beat sequence of the patient's heart. A fiducial time marker is obtained for a candidate heart beat. A quality index of said candidate heart beat is set to a first value. The candidate heart beat is tested with at least one beat validity test. At least a second value is added to said quality index of said candidate heart beat if said candidate heart beat passes said at least one beat validity test. The candidate heart beat is tested with at least a second heart beat validity test. At least a third value is added to said quality index of said candidate heart beat if said candidate heart beat passes said at least second heart beat validity test.

  • Patent number: 9700256
    Abstract: Methods, systems, and apparatus for detecting the seizure in a patient using a medical device. The determination is performed by collecting cardiac data; determining valid heart beats suitable for seizure detection from the cardiac data; calculating heart rate data of interest from the valid heart beats; and identifying a seizure event from the heart rate data. The medical device may then take a responsive action, such as warning, logging the time of the seizure, computing and storing one or more seizure severity indices, and/or treating the seizure.

  • Patent number: 9659216
    Abstract: A method, computer program, and system for real-time signal analysis providing characterization of temporally-evolving densities and distributions of signal features of arbitrary-type signals in a moving time window by tracking output of order statistic filters (also known as percentile, quantile, or rank-order filters). Given a raw input signal of arbitrary type, origin, or scale, the present invention enables automated quantification and detection of changes in the distribution of any set of quantifiable features of that signal as they occur in time. Furthermore, the present invention's ability to rapidly and accurately detect changes in certain features of an input signal can also enable prediction in cases where the detected changes associated with an increased likelihood of future signal changes.

  • Patent number: 9072832
    Abstract: Apparatus and method detect a detection cluster that is associated with a neurological event, such as a seizure, of a nervous system disorder and update therapy parameters that are associated with a treatment therapy. The occurrence of the detection cluster is detected when the maximal ratio exceeds an intensity threshold. If the maximal ratio drops below the intensity threshold for a time interval that is less than a time threshold and subsequently rises above the intensity threshold, the subsequent time duration is considered as being associated with the detection cluster rather than being associated with a different detection cluster. Consequently, treatment of the nervous system disorder during the corresponding time period is in accordance with one detection cluster. Treatment therapy may be provided by providing electrical stimulation, drug infusion or a combination.
