Abstract: An apparatus for detecting when a subject has exited an item of furniture is provided. The apparatus comprises a camera adapted to be arranged, when in use, below the underside of an item of furniture having an upper side for supporting a subject, the underside being opposite to the upper side, and a processing unit. The camera captures sequential images that do not include the upper side of the item of furniture, the images having a foreground corresponding to a region below the underside of the item of furniture and a background corresponding to a region adjacent the item. The processing unit receives images from the camera; detects, for each image, an edge corresponding to an edge of the item; detects the appearance of a feature contiguous with the edge; monitors how a detected feature changes over a time period; determines whether a change to the detected feature satisfies at least one predefined criterion for a subject exit event; and outputs a signal based on the determining.

Abstract: The present invention relates to a system (10) for monitoring a vital sign of a first subject (12), for example, a neonate, which is in proximity or in contact with a second subject (14), for example, a parent. The system comprises an imaging unit (16) for monitoring the first subject (12) from a distance, to obtain an imaging signal related to a first vital sign of the first subject (12), this imaging unit (16) might be, for example, a camera. The system further comprises a sensing unit (18) for obtaining a sensor signal related to a second vital sign of the second subject (14). The sensing unit (18) is arranged in proximity or at the second subject (14). The first vital sign is of the same type as the second vital sign, thus an analyzing unit (20) can be used for deriving the first vital sign of the first subject (12) from said imaging signal by taking into account said sensor signal.

Abstract: There is provided an apparatus for monitoring a subject occupying an item of furniture. The apparatus comprises a projector for fixed attachment to a moveable part of an item of furniture, which changes its position and/or orientation relative to a surface in response to a movement of a subject occupying the item of furniture. The projector is arranged to project a pattern onto the surface. The apparatus further comprises at least one camera arranged to capture sequential images of the surface; and a processing unit. The processing unit is arranged to: receive the images from the at least one camera; detect the projected pattern in the received images; detect a change to at least one feature of the projected pattern in the received images; determine whether the detected change satisfies at least one predefined criterion for a subject exit event; and output a signal based on the determining.
