    摘要： Fluid lens system, e.g. for medical imaging or medical treatment, with a container enclosing a fluid arranged to refract incoming waves. A pressure release mechanism is in contact with the fluid so as to compensate changes in its volume due to thermal variations, e.g. during high temperature medical cleaning. This pressure release mechanism is positioned within a pathway of incoming waves. In preferred embodiments a fluid container connected via a tube to the fluid as a reservoir, is arranged within or outside the container, e.g. beyond an image sensor. Alternatively, an easily compressible body, e.g. a small closed metal bellows enclosing a gas, is positioned inside the fluid to absorb volume changes by compression. In both embodiments, the pressure release elements are preferably positioned in a peripheral part of the pathway of incoming waves to not affect performance of the lens. In another aspect, a fluid lens includes a container with an inner container part that fits inside an outer container part, wherein the inner container part is in rigid connection to at least a one boundary arranged for penetration of incoming waves. The pressure release mechanism is positioned within the outer container part, and it is in contact with the fluid so as to compensate changes in volume of the fluid due to thermal variations. In one embodiment the inner and outer container parts are arranged for relative one-dimensional movement and fluid tight interconnected. In another embodiment, a fluid filled cavity is formed between the inner and outer container parts, and this cavity houses a compressible body. The lens systems are suited for applications such as medical endoscopes, catheters and needles, optically as well as acoustically based.

    摘要： An optical pickup unit for an optical disk drive, comprises a lens holder (27) including a lens having an optical axis, suspension wire members (33-36) suspend the lens holder (27) in a support frame in a cantilever fashion. The wire members constrain movement of the lens holder relative to the support frame, but allowing at least a translation in a focussing or axial direction (z), parallel to the optical axis of a lens in the lens holder (27). The wire members are fixed to the lens holder in positions at a distance from each other at least in focussing and tracking directions (z, x). The wire members are bent around an axis parallel to the radial direction (x) so as to allow an at least limited rotation about an axis in a tracking or radial direction (x) as well. In this way, an active alpha tilt correction is made possible with simple means.

    摘要： A disk drive unit having a disk loading mechanism, for use in a mobile device. The loading mechanism is arranged for receiving a disk (A) through an opening in a housing of the device and bringing it into engagement with the disk drive, and vice versa. It comprises a tray (8) which is movable with respect to the housing and the disk drive between a first position for receiving a disk and a second position covering the opening and allowing the disk drive to engage the disk. The tray is rotatable about an axis (10) which substantially coincides with the drive axis (11) when in its driving position. This arrangement results in a slot loader having a tray which will hardly project outside the housing, resulting in a robust loading mechanism.

    摘要： A needle device according to the invention comprises a hollow shaft, an elongated insert and an operating means. The hollow shaft has a first distal end portion with a bevel, the elongated insert has a second distal end portion and is movably arranged within the hollow shaft, and the operating means is shiftable between a first condition and a second condition. Furthermore, the operating means is interconnected with the elongated insert, so that the second distal end portion is located within the hollow shaft and proximally to the bevel, when the operating means is in the first condition, and that the second distal end portion is located outside the hollow shaft and distally to the bevel, when the operating means is in the second condition.
