摘要： A disk drive unit for a disk, e.g. for use in a mobile device, comprises a spindle (1) positioned within the disk drive unit and adapted to support the disk rotatably in an operating position. An electric motor (2) is operatively coupled to the spindle (1) to rotate it. An auxiliary electric motor (3) is connectable to the spindle to accelerate the spindle during start-up. This auxiliary motor can be selected to work efficiently at zero speed. The electric motor may be a low-power motor, resulting in a reduced power consumption.

摘要： A disk drive unit for a removable disk (D), in particular for use in mobile devices, comprises a spindle (1) driven by an electric motor (2) and supporting the disk (D) in its operating position. It further comprises one or two loading mechanisms (4A and 4B) to load mechanical energy into a storage mechanism (5) for storing the loaded energy. A release mechanism (6) is provided to release the stored energy stepwise to the spindle in order to assist during a plurality of start-ups of the disk rotation. The two loading mechanisms (4A and 4B) are adapted to load mechanical energy provided by the user during insertion of the disk and energy released during the deceleration of the rotation of the disk, respectively. The electrical power consumption of the disk drive unit is reduced by the storage of the mechanical energy and its stepwise release.

摘要： A transducer device for detecting an environmental state within a biological material including a channel comprising a fluid, a hydrogel material, which is adapted to change its volume when getting into contact with an environmental material and/or when detecting an environmental change, and which is mechanically coupled to the channel such that the volume of the channel changes when the volume of the hydrogel material changes. The transducer device further includes a sensor, which is adapted to generate a signal upon detection of the change of a physical property of the fluid that is induced by the volume change of the channel. By applying the transducer device, an accurate monitoring of physiological parameters, for which the hydrogel material is sensitive is possible. It is also possible to apply the transducer device outside of the bodily lumen, for example to monitor the blood of a patient outside the bodily lumen.

摘要： The invention relates to a method and a device for driving an LED string of a first LED segment (11) and at least one further LED segment (12, 13, 14) connected in series. Each LED segment has at least one light emitting diode, LED. The LED string is powered by a rectified AC mains voltage. The first LED segment (11) is powered when the rectified AC mains voltage is above a first voltage level, and the first LED segment and the further LED segment are powered when the rectified AC mains voltage is above a second voltage level higher than the first voltage level. The first LED segment emits light having a first color temperature, and the further LED segment emits light having a second color temperature higher than the first color temperature. The light emitted by the first LED segment and the light emitted by the further LED segment are superimposed. The color temperature change of the light emitted by the LED string, when dimmed, resembles the color temperature change of an incandescent lamp.

摘要： There is provided an arrangement for spot illumination (14). The arrangement provides an improved collimation and color mixing unit comprising a LED array (1), a convex shaped reflector (15a), a field lens (21) and an additional cylindrical reflector (15b) at the exit aperture of the system. In combination with an optical projection system which may comprise at least two additional zoom lenses and a gate (in which several maskers, gobos or shutters could be inserted) the system allows color mixing in an extended operational range including out of focus zoom settings often used to get soft edge spots.
