Abstract: A main stream contains successive content elements of video and/or audio information that encode video and/or audio information at a first data rate. A computation circuit (144) computes main fingerprints from the successive content elements. A reference stream is received having a second data rate lower than the first data rate. The reference stream defines a sequence of the reference fingerprints. A comparator unit (144) compares the main fingerprints with the reference fingerprints. The main stream is monitored for the presence of inserted content elements between original content elements, where the original content elements have main fingerprints that match successive reference fingerprints and the inserted content elements have main fingerprints that do not match reference fingerprints. Rendering of inserted content elements to be skipped. In an embodiment when more than one content element matches only one is rendered.

Abstract: The present disclosure pertains to a system configured to determine one or more parameters based on cardiorespiratory information from a subject and determine sleep stage classifications based on a discriminative undirected probabilistic graphical model such as Conditional Random Fields using the determined parameters. The system is advantageous because sleep is a structured process in which parameters determined for individual epochs are not independent over time and the system determines the sleep stage classifications based on parameters determined for a current epoch, determined relationships between parameters, sleep stage classifications determined for previous epochs, and/or other information. The system does not assume that determined parameters are discriminative during an entire sleep stage, but maybe indicative of a sleep stage transition alone. In some embodiments, the system comprises one or more sensors, one or more physical computer processors, electronic storage, and a user interface.

Abstract: In one embodiment, an apparatus is presented that receives a driving style of a driver, senses a parameter or parameters of a driver and/or at least one passenger within a vehicle, correlates the parameter(s) to the driving style, and triggers feedback to the driver of the correlated parameter(s) of the at least one passenger or to the passenger of the correlated parameters parameter(s) of the driver. The invention provides, among other features, a mechanism to increase positive interactions between the driver and the passenger(s) and to decrease or avoid negative interactions, which leads to a safer use of the vehicle based on the correlations between measured health/well-being data and driving style or behavior.

In particular, it can be determined that the heart failure risk is relatively large, if a PESP is not present and/or if the FFR is disturbed.

Abstract: The invention relates to a determination system for determining a heart failure risk for a subject (4). The determination system (1) comprises a photoplethysmogram providing unit for providing a photoplethysmogram of the subject and a heart failure risk determination unit for determining the heart failure risk based on the provided photoplethysmogram.

The heart failure risk can therefore be determined in a technically relatively simple way without requiring a physician's attendance.

Abstract: A subject behavior monitoring device is for monitoring the behavior of a subject based on their usage of a plurality of fluid outlets of a fluid supply system in a building. An acoustic measurement unit is adapted to generate an acoustic monitoring signal which varies in dependence on a fluid flow from the plurality of fluid outlets.
