Periodic data is analyzed by obtaining a vector of delay coordinates for each one of a plurality of samples of the periodic data in a time window, and transforming each of the vectors into a coordinate system comprising a plurality of predefined vectors, to obtain a projection of an attractor of the periodic data along one of the predefined vectors. The periodic data may be physiological data. Information representing one or more characteristics of the obtained attractor, which is of diagnostic value, is then displayed to enable a diagnosis.

Some embodiments include apparatuses and methods having a receiver unit included in a die and a measurement unit included in the die. The receiver unit includes a sampler to sample a first signal based on timing of a first clock signal to generate a second signal. The measurement unit is arranged to sample the first signal based on timing of a second clock signal to provide information for generation of a graph presenting an eye scan of the first signal. The second clock signal has a frequency asynchronous with a frequency of the first clock signal.

A method and apparatus are provided for characterizing a product sample for example in comparison to a reference sample using a sensor such as a gas chromatograph or a MOS sensor. This characterization may comprise an indication of whether or not the product sample conforms to a quality criterion. The comparison of the sensor output measurements for the product sample is compared to maximum and minimum value curves, which may be derived from measurements of the reference sample, whereby adjacent samples outside the envelope defined by these maximum and minimum values are grouped together. A dissimilarity index may be determined for the anomalous values as a whole, or on a per group basis. The groups may be classified depending on the shape they describe, in particular the presence, or not, of peaks, and correspondingly the shape of the corresponding part of the envelope. These determinations may then be used as the basis of the conformity indication, and also the basis for attempting to identify the cause of any anomalies, in particular the identification of foreign components.

Disclosed herein are methods and systems for detection and discrimination of optical signals from a densely packed substrate. There have broad applications for biomolecule detection near or below the diffraction limit of optical systems, including in improving the efficiency and accuracy or polynucleotide sequencing applications.

In one embodiment, a method includes receiving, from one or more cameras, video data associated with a first user performing a plurality of actions of a first action-type. The cameras may be positioned to observe one or more biomechanical acts of the first user and an outcome for each action. The video data may be optically processed to determine a plurality of sets of action-parameter values corresponding to the respective plurality of actions. Each action-parameter value may be based on biomechanical acts for the respective action from the video data. Outcome data corresponding to the respective plurality of actions may be determined based on the video data. An athletic-performance model of the first user may be generated based on the sets of action-parameter values. The athletic-performance model may be a statistical model including probabilities computed with respect to the sets of action-parameter values and the outcome data.

Systems and techniques for a sensor network for trick classification are described herein. A first data stream may be received from a first sensor array affixed to a first free-moving body of a sporting device. A second data stream may be received from a second sensor array affixed to a second free-moving body of the sporting device. A trick region of a predetermined length of the first data stream corresponding with an occurrence of a trick may be determined using data from the first data stream. The trick may be classified using a first set of data from the first data stream corresponding with the trick region and a second set of data from the second data stream. The second set of data may be obtained by aligning the trick region of the first data stream with the second data stream

An image processing apparatus includes a first phase difference detector configured to detect two phase differences in a range that contains a phase difference that provides the highest correlation between a pair of image signals, a comparator configured to compare a signal representative of a matching degree when the pair of image signals have a first phase difference among the two phase differences, and a signal representative of a matching degree when the pair of image signals have a second phase difference among the two phase differences, a signal separator configured to separate a pair of signal components relating to a specific object from the pair of image signals, based on a comparison result by the comparator, and a second phase difference detector configured to detect a phase difference that provides the highest correlation between the pair of signal components separated by the signal separator.

In embodiments of the present invention, periodic data is analysed by obtaining (S1) a vector of delay coordinates for each one of a plurality of samples of the periodic data in a time window, and transforming (S2) each of the vectors into a coordinate system comprising a plurality of predefined vectors, to obtain a projection of an attractor of the periodic data along one of the predefined vectors. The periodic data may be physiological data. In-formation representing one or more characteristics of the obtained attractor, which is of diagnostic value, is then displayed (S3) to enable a diagnosis.
