This disclosure relates to a cooling structure for an electronic device including an inlet for conveying a flow in a first flow direction towards a first component and an outlet for conveying the flow further. To deter dirt particles from proceeding to electronic components, the cooling structure can include a second flow channel, which starts from a port oriented transversely to the first flow direction or away therefrom and receives part of the flow from the inlet, and which conveys the part of the flow to an electronic component located in the second flow channel.

Cooling structure for electronic device, and a method

A choke device for a frequency converter, comprising three windings composed of conductors wound around three substantially parallel axes (A, B, C), respectively, the windings being located triangularly with respect to each other in such a manner that, when the choke device is viewed in the longitudinal direction of said winding axes (A, B, C), the winding axes are located at the vertices of the triangle, the choke device further comprising an envelope () surrounding the windings, a first end (A) thereof being provided with at least one opening () for receiving cooling medium to the inside of the envelope, and a second end (B) being provided with at least one opening for discharging the cooling medium from the envelope, and an envelope axis (D) between said first and second ends being substantially parallel with the winding axes (A, B, C).

The invention relates to a supporting cushion intended for aligning or positioning the RF-coils of a magnetic resonance imaging apparatus and a patient, which cushion can serve as a part of the RF-coil and which is capable of providing a support for the RF-coil and the patient in accordance with the anatomy of an individual patient. Air is pumped in the cushion for giving the supporting cushion a desired thickness. The cushion is placed against the RF-coil in a manner that, by pumping air therein, said cushion presses the soft and yielding RF-coil against the patient. The cushion can be used e.g. in back and neck coils. The cushion can also be fitted between a patient's supporting rest and a patient in a manner that a section of the patient to be imaged is immobilized for the duration of imaging. For example, the head can be supported or braced this way by fitting the cushion between the head and a head rest.

Anatomic support for an MRI-apparatus

A mechanism for transporting a patient to a magnetic resonance unit. A coil seat is mounted on the upper surface of a lower bed and the lower bed is mounted for movement relative to a magnet. An upper bed is mounted for movement on the lower bed. In the positioning stage, the coil is located outside of the magnet and the upper bed carrying a patient is moved relative to the lower bed to position the patient in registry with the coil, such that a desired anatomical area is brought into the imaging area of the coil. This is followed by pushing the upper and lower beds as a unit into the bore of the magnet. As various coils can be positioned on the lower bed at a common positioning location, it is possible to employ a common electric connection to eliminate the need for separately attachable cables.

An apparatus for the implementation of a vertical movement for a chair, especially a patient chair is disclosed. This apparatus comprises a lift column (1) with an upper end suitable for mounting a chair, a tubular shell construction (2) against which the lift column (1) is telescopically supported, a threaded member (5) whose rotation enables elevation and lowering of the lift column (1), and a motor (4) for rotating the threaded member (5). In the apparatus according the lift column (1) has a polygonal cross section, and it receives for each of its sides a support incorporating a spring action and sliding bearing contact by support braces (3) mounted to the inner surface of the shell construction (2). The apparatus achieves a vibration-free lift movement.
