    Abstract: The sleep monitoring system uses a motion vector estimator to determine motion vectors as a function of location in camera images. A signal processing system with an input coupled to the motion vector estimator computes a measure of turning motion, by summing motion vectors from respective locations within an image. Pose changes are detected based on the measure of turning motion. The measure of turning motion may be computed from a sum of components of the motion vectors that are normal to the major axis of a body area in the image, which is determined based on image content changes in a set of images from the camera. To avoid false turning detection due to leg kicking or similar motion the detected turning motion may be reduced to zero if it is not detected in a sufficiently large part of the body area.

    Abstract: An oral care device (10) assesses a health parameter of gingival tissue of a user by means of a force-generating module (52) to apply a momentary force to the gingival tissue by applying a burst of compressed air or a burst of liquid to the gingival tissue, a sensor (28) to obtain a plurality of optical signals from the gingival tissue over time after the momentary force has been applied, a controller (30) to quantify, based at least in part on an analysis of the plurality of optical signals, the health parameter (e.g. inflammation of the gingival tissue), wherein the health parameter is based at least in part on an amount of time the gingival tissue takes to recover to the application of force; and a feedback module (46) to provide information to the user regarding the quantified health parameter.

    Abstract: A method of facilitating obtaining a first signal, for analysis to characterize at least one periodic component, includes obtaining two second signals representative of intensities of electromagnetic radiation. The first signal is at least derivable from an output signal obtainable by applying a transformation to the second signals such that any value of the output signal is based on values from each respective second signal at corresponding points in time. The method further includes obtaining a value of a variable determining influences of components of respective second signals on the output signal when the signals corresponding to the second signals are captured and the transformation is applied, by (i) analyzing the first, second and/or the output signals to select a value of a parameter corresponding to a respective one of the variables; or (ii) calculating values of at least one time-varying factor corresponding to a respective one of the variables.

    Abstract: A method (300) for characterizing color information about a tooth, comprising: (i) projecting (320) at least one predetermined color pattern (400); (ii) obtaining (330), using an imager (10), one or more images (90) each containing both a projected first predetermined color pattern (400) and at least a portion of a user's mouth (500); (iii) automatically identifying (340) by a controller (30), from the obtained one or more images, one or more teeth (510) in the at least a portion of the user's mouth (500( ); (iv) comparing (350) an imaged predetermined color pattern to a corresponding projected predetermined color pattern; and (v) extracting (360) by the controller, based on the outcome of the comparison, color information about the one or more identified teeth (510).
