Publication number: 20180152943Abstract: 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.Type: ApplicationFiled: January 29, 2018Publication date: May 31, 2018Inventors: Timothy James Moulsley, Choo Chiap Chiau, Milos Tesanovic, Robert James Davies

Publication number: 20170220525Abstract: 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.Type: ApplicationFiled: August 27, 2015Publication date: August 3, 2017Applicant: KONINKLIJKE PHILIPS N.V.Inventors: CHOO CHIAP CHIAU, QI ZHONG LIN, TAK MING CHAN, YUGANG JIA

Publication number: 20170156681Abstract: 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.Type: ApplicationFiled: June 26, 2015Publication date: June 8, 2017Inventors: TAMARA MATHEA ELISABETH NIJSEN, CHEVONE MARIE BARRETTO, CHOO CHIAP CHIAU, MAREIKE KLEE
