Abstract: A nebulizer comprises a head detachably coupled to a body. The head comprises nebulizing means, an air channel and a flow sensor. A nebulized liquid is released in an air channel that ends in a mouth piece through which a user inhales and exhales. The inhaling and exhaling causes a flow in the air channel which is detected with the flow sensor. The nebulizing means are controlled by control means included in the body.

Abstract: A thermal flow sensor integrated circuit for sensing flow in a channel based on temperature measurements, the integrated circuit having a temperature sensing element (30) on a front side of the integrated circuit arranged to face the channel, and a bond pad (60, 200) coupled electrically to the temperature sensing element, for making electrical contact off the integrated circuit, the bond pad being arranged to face away from the channel. By having the bond pad facing away from the channel, the space needed for the bond pad and any connections to it need not extend beyond the temperature sensing element and get in the way of the channel. Hence the temperature sensing element can be located closer to the channel or in the channel to enable measurements with better response time and sensitivity.

Abstract: An aerosol generation system has a light source arrangement which provides signals at first and second wavelengths, and the detected light signals are recorded. The detected signals are processed to derive at least a measure of the aerosol particle size. This can be used in combination with the other parameters which are conventionally measured, namely the aerosol density and flow velocity. Thus, optical measurement (possibly in combination with an air flow measurement) can be used to estimate the aerosol output rate as well as the particle size.

Abstract: A nebulizer (10) comprises a head detachably coupled to a body. The head comprises nebulizing means (42, 40, 44), an air channel (50) and a flow sensor (52). A nebulized liquid is released in an air channel (50) that ends in a mouth piece 70 through which a user inhales (5) and exhales (7). The inhaling and exhaling causes a flow in the air channel which is detected with the flow sensor (52). The nebulizing means are controlled by control means (60, 62) included in the body.

Abstract: A nebulizer (1) comprises one or more removable components (5,7,9,13), for example a mesh assembly (9), mouthpiece, plunger assembly (7) and medication chamber (13), each having an associated data carrier (5a, 7a, 9a). The data carrier (5a, 7a, 9a) can be used to store information indicating the type of removable component (5,7,9,13) that is fitted to the nebulizer (1). A removable component (5,7,9,13) may be from a set of such removable components. For example, a mouthpiece (5) fitted to the nebulizer (1) may be from a set of mouthpieces having different flow rates. The data carrier (5a, 7a, 9a) may also be used to control operation of the nebulizer (1). A data carrier (9a) attached to a mesh (9) may be used to prevent the nebulizer (1) from being used when the mesh (9) has been used a predetermined number of times.

Abstract: An automatic update is performed by an archiving device that controls the device carrying the sequentially accessible recording medium. The update can be performed according to a full scan algorithm or to an append algorithm. Both algorithms arrange things so that only those scenes are captured to the archiving medium that are more recent than the last scene captured in a previous session. The reference for the age is the Recording Date and Time. The full scan algorithm does not make assumptions about how a recording medium has been recorded, whereas the append algorithm is intended for recording media used by appending new material after old material. The method of capturing scenes is especially useful for a disk recorder. The data captured may be an audio/video-stream of a camcorder or the files of a personal computer.

Abstract: A diffuse optical tomography device comprises a light source for irradiating a mammalian body part, a holding device configured for holding the body part, a measuring device configured for measuring the light level in the holding device and the ambient light level and a controlling device configured for controlling the light source as a function of the measured light level in the holding device and the ambient light level. Such a device prevents light leakage into the eyes of a patient or an operator.

Abstract: The invention relates to a method, device, and medical image acquisition device for imaging an interior of a turbid medium. The method comprises the following steps: accommodation of the turbid medium inside a receiving volume (5); coupling light from an irradiation light source into the receiving volume (20); detecting light emanating from the receiving volume as a result of coupling light from the irradiation light source into the receiving volume (25); reconstructing an image of an interior of the turbid medium on the basis of detected light (30). It is an object of the invention to reduce the effect of light from a light source other than the irradiation light source on image quality.
