Abstract: A method of generating a reduced palette for use in a printing process is disclosed. In the method, a plurality of images obtainable by varying printing parameters of the printing apparatus are printed, and color values of the same are measured. Based on the color values, a clustering is performed to obtain a plurality of clusters having similar color values. For each cluster, one or more representative images are selected to form the palette. In this manner, images with color values both inside a convex hull and on the convex hull can be included in the palette.

Abstract: A system for determining a pulse velocity wave comprises an interface for receiving a signal indicating the proximal blood pressure in an artery and for receiving a signal indicating distal blood pressure in the artery. A processing device is configured to determine a proximal rising edge between a diastolic pressure and the systolic pressure of the proximal signal; determine a proximal pressure peak prior to the proximal rising edge; determine a distal rising edge between a diastolic pressure and a systolic pressure of the distal signal; determine a distal pressure peak prior to the distal rising edge and to determine whether the distal pressure peak is in phase advance with respect to the proximal pressure peak; and determine a propagation velocity of a regressive pulse wave depending on the phase advance of the distal pressure peak.
