Abstract: A method of processing images of at least one living being, includes obtaining a sequence (19) of digital images taken at consecutive points in time. At least one measurement zone (26) comprising a plurality of image points is selected. For each measurement zone (26), a signal (28,30) representative of at least variations in a time-varying value of a combination of pixel values at at least a number of the image points for use in determining at least one of a presence and a frequency value of at least one peak in a spectrum of the signal (28,30) corresponding to a frequency of a periodic physiological phenomenon is obtained. The step (25) of selecting at least one measurement zone (26) includes analyzing information based on pixel data of a plurality of image parts in at least one of the images (19), each image part including at least one image point, and selecting each measurement zone (26) from contiguous parts determined to have similar characteristics.

Abstract: The present invention relates to a temperature control apparatus for thermoregulation of a human body, comprising at least one radiation absorption panel with at least one surface capable of absorbing thermal radiation, and a cooling device provided to cool said panel. A sleeping accommodation for a human being comprises a lying area and such a temperature control apparatus, wherein the radiation absorption panel is disposed adjacent to the lying are or above the lying area. The invention further relates to a corresponding method for thermoregulation of the human body.

Abstract: The invention relates to a sleep element (1) like a heating blanket for improving the sleep of a person. The sleep element comprises a property determination unit (2, 5) for determining a property of a person, a thermal energy unit (3) for transferring thermal energy to or away from the person, and a thermal energy control unit (4) for controlling the thermal energy unit depending on the determined property of the person. Since the sleep element comprises the property determination unit, the thermal energy unit, and the thermal energy control unit, the temperature of the person can be controlled depending on a determined property of the person, while the person is sleeping, such that the sleep of the person is improved. Moreover, the temperature control can simply be used within a bed by placing the sleep element in the bed. The handling of the temperature control is therefore very simple.

Abstract: A fragrance apparatus comprising a fragrance dispensing unit having a plurality of fragrance dispensers being refillable, the fragrance dispensing unit being disposed in a modular housing unit and a control unit disposed in the modular housing unit, the control unit configured to control the fragrance apparatus such that the fragrance dispensing unit generates a spatio-temporal pattern of fragrance and/or removes the generated spatio-temporal pattern of fragrance is disclosed. The disclosed fragrance apparatus is useful in atmosphere creation.

Abstract: A display (1) for displaying an image and a method for driving such display is proposed. Therein, the display comprises: a background light (31), a first LCD panel (3) defining an array of pixel elements (13), a second LCD panel (5) defining an array of pixel elements (29) and a control unit (37) for driving the first and second LCD panels (3, 5). The second LCD panel (5) is a color display and is arranged between the first LCD panel (3) and the background light (31). The control unit (37) is adapted to control the second LCD panel (5) such that a white color point of the display (1) may be adjusted. Preferably, a diffuser (33) is arranged between the first display (3) and the second display (5).

Abstract: A liquid crystal display comprising first and second liquid crystal display panel (1, 3), each defining an array of picture elements (13, 15). The resolution of the image displayed on the second liquid crystal display panel (3) is lower than that of the image displayed on the first liquid crystal display panel (1). The picture elements (15) of the second liquid crystal display panel (3), located between the first liquid crystal display panel (1) and backlighting means (2) may be relatively large and preferably partially overlap at least in one direction. A charge is selectively applied to the picture elements (15) of the second liquid crystal display panel (3) corresponding to the relatively darker portions of the image to be displayed on the first liquid crystal panel (1), so as to at least limit the amount of light reaching these portions of the first liquid crystal display panel (1) and thereby increasing the contrast trio of the device.
