Abstract: Systems and methods for detecting changes in a physiological system are provided. A method comprises embedding time series data relating to the physiological system within a reconstructed phase space and partitioning the reconstructed phase space into a plurality of regions. The method further comprises generating a first matrix having a plurality of cells. A value stored in each cell is based on a probability that the system will transition from a first region associated with the cell to a second region associated with the cell and a rate of separation of trajectories of the embedded data within at least one of the first region and the second region. The first matrix is associated with a normal operating condition of the physiological system. The method further comprises comparing the first matrix and a second matrix based on different data to detect an anomalous condition of the physiological system.

Abstract: One embodiment of the disclosure relates to a method of detecting a change in the state of a system. The method comprises embedding time series data relating to the system within a reconstructed phase space having a D-dimensional embedding dimension. D is greater than two. The method further comprises enclosing the reconstructed phase space in a D-dimensional bounding space and partitioning the bounding space into a plurality of regions. The method further comprises generating a matrix having a plurality of cells. The matrix comprises a row and a column for each of the plurality of regions. A value stored in each cell is based on a probability that the system will transition from a first region associated with the cell to a second region associated with the cell and a rate of separation of trajectories of the embedded data within at least one of the first region and the second region.

Abstract: Methods of analyzing solutions to a failure of a product are provided. A method comprises evaluating the fitness of solutions associated with a plurality of individuals in a population for the failure. Each of the plurality of individuals comprises a dominant genotype and a recessive genotype. Each genotype represents a solution for addressing a potential failure of the product. A fitness function is applied to the dominant genotype of each individual. The fitness function is configured to determine a confidence value for one or more of the solutions based on historical data regarding the solutions that is stored in a database. The method further comprises storing previously encountered genotypes in the recessive genotypes of the individuals and determining a proposed solution for addressing the failure of the product based on the fitness evaluation.

Abstract: A method of detecting a potential security threat on a computing system is provided. The method comprises embedding time series data relating to the computing system within a reconstructed phase space and partitioning the reconstructed phase space into a plurality of regions. The method further comprises generating a first matrix having a plurality of cells. The first matrix comprises a row and a column for each of the plurality of regions. A value stored in each cell is based on a probability that the system will transition from a first region associated with the cell to a second region associated with the cell and a rate of separation of trajectories of the embedded data within at least one of the first region and the second region. The first matrix is generated using a first set of the time series data that is associated with a normal operating condition of the computing system in which the computing system is not under attack from a security threat.

Abstract: A device for collecting biological specimens having a container and a detachable handle. The handle allows a person to position the container so that contact between the person and sample is minimized or avoided. The handle includes a hoop into which the container slides from the container's lower end. The container is configured with projections on its outer surface that frictionally engage the hoop. Alternatively, the container can be configured with projections, a ring, or a lip over which the hoop is obliquely traversed to prevent the hoop from sliding downward on the outer surface of the container. The handle is constructed of a flexible material so that it may deform as needed when engaging the outer surface of the container.

Abstract: A specimen gathering device permitting a person to position the specimen gathering device without contact with the specimen. The device includes a container member having an overlying lid and detachable handle assembly diametrically overlying the lid and forming a lever for tightening and loosening the lid. Releasable gripping members on the container wall, handle and lid permit manual separation of the handle and lid and supporting the container remote from a person's hand by one end portion of the handle.

Abstract: A device for holding and positioning a specimen cup for collection of a biological specimen with a ring (18) with a handle (14) attached by a hinge (24). The ring (18) receives and securely supports a specimen cup. The hinge (24) allows the handle (14) to assume folded or extended positions relative to the ring (18). The handle (14) extends outward and upward from the ring (18) when in use, thereby, removing one's hand from the specimen cup. One can then more easily hold and position the specimen cup without soiling their hand with the specimen. The hinge (24) also allows the handle (14) to be folded and secured to the ring (18) to facilitate packaging.
