  • Publication number: 20180152943
    Abstract: A method of communicating between a primary station and a plurality of secondary stations is described. According to one aspect, the secondary station monitors a control channel search space for a control message from a primary station intended for the communication device. According to an aspect, the control message is indicative of a resource allocated to the secondary station for communicating with the primary station and the resource corresponds to a component carrier. The secondary station determines a control channel from the control channel search space having the control message intended for the secondary station and determines, based on a presence of the control channel on a specific component carrier, the indication of a resource set from a plurality of resources sets in which the resource allocated to the secondary station is located.

  • Publication number: 20170220525
    Abstract: The present invention generally relates to accessing data selected by a user based on correlation analysis. It is proposed in the present invention to introduce attribute value normalization and a hierarchical data analysis based on mutual correlations between attributes. Normalization of scale values of attributes to nominal values provides a basis for the hypothesis of correlations between attributes, thus scientifically justifying further observation and comparison. Multiple layer hierarchical investigation enables not only analysis on the level of attributes but also of related data, which provides a more detailed observation.

  • Publication number: 20170156681
    Abstract: The present invention relates to an apparatus, a system (100), a method (200), and a computer program for assessing the risk of an exacerbation and/or hospitalization. A patient's physical activity is measured (e.g., by an accelerometer (110)) during an active period of time (e.g., during awake hours) and during a rest period of time (e.g., during sleep hours) to gather first and second activity data. A risk of exacerbation and/or hospitalization is assessed (e.g., by a risk assessment unit (120)) based on an expression involving the respective activity data during active and rest periods fulfilling a predetermined relationship with respect to a predetermined activity level. For instance, low activity data during active periods and high activity data during rest periods indicates an increased risk of exacerbation and/or hospital readmission for the patient.

  • Publication number: 20150324541
    Abstract: Embodiments of the invention provide for a health monitoring system comprising an activity monitor. The health monitoring system further comprises a processor and a memory for storing machine readable instructions. The instructions cause the processor to derive activity counts from the activity data acquired by the activity monitor. The instructions further cause the processor to store the activity counts in the memory, and are associated with a time. The instructions further cause the processor to calculate at least two statistical parameters from the activity counts, wherein the at least two statistical parameters are descriptive of the activity counts as a function of time. The instructions further causes the processor to calculate a risk score for each of the at least two statistical parameters. The instructions further cause the processor to calculate a total risk score using the risk score for each of the at least two statistical parameters.
