Abstract: A cardiac state system, comprising a processing unit (4) configured to receive input signals (6) including parameters from, or related to, one or many registration points or areas within or outside a heart (8), and a storage unit (10) where one or many search tools are stored. The processing unit (4) is configured to process the input signals (6), by applying said search tools, to identify point of interests (POI), being landmarks, patterns and/or group patterns. The processing unit (4) is further configured to search for and identify global and/or regional event markers among said POIs to evaluate hydro-mechanical and/or hydro-dynamic functions of the heart. Preferably, at least some of said identified event markers are associated to the AV-piston defined according to the dynamic adaptive piston pump (DAPP) technology.

Abstract: Arrangement for the production of instantaneous or non-instantaneous multi-band images, to be transformed into multi- or hyperspectral images, comprising light collecting means, an image sensor array, and an instantaneous colour separating means, positioned before the image sensor array, and uniform spectral filters, for restricting imaging to certain parts of the electromagnetic spectrum. A filter unit is positioned before the colour separating means in the optical path in, or close to, converged light. Each filter mosaic consists of a multitude of homogeneous filtering regions. The transmission curves of the filtering regions of a colour or spectral filter mosaic can be partly overlapping, in addition to overlap between these transmission curves and those belonging to the filtering regions of the colour separating means. The transmission curves of the colour or spectral filter mosaics and the colour separating means are suitably spread out in the intervals of a spectrum to be studied.

Abstract: The present invention relates to the production of instantaneous or non-instantaneous multi-band images, to be transformed into multi- or hyperspectral images, comprising light collecting means (11), an image sensor (12) with at least one two dimensional sensor array (121), and an instantaneous colour separating means (123), positioned before the image sensor array (121) in the optical path (OP) of the arrangement (1), and first uniform spectral filters (13) in the optical path (OP), with the purpose of restricting imaging to certain parts of the electromagnetic spectrum. The present invention specifically teaches that a filter unit (FU) comprising colour or spectral filter mosaics and/or uniform colour or spectral filters mounted on filter wheels (114) or displayed by transmissive displays (115), is either permanently or interchangeably positioned before the colour separating means (123) in the optical path (OP) in, or close to, converged light (B).
