A method and arrangement for blood pressure measurement are disclosed. In the method, a variable, compressive, acting pressure is applied to a compression, such as a person's extremity, by a pressure generator, and simultaneously, the effect of the variable acting pressure on the extremity is measured at a second point, the second point being farther from the heart than the compression point. The ...

The invention relates to a method and arrangement for blood pressure measurement. In the method, a variable compressive acting pressure is applied to a measuring point, such as a person's extremity at a compression point by a pressure generator, and at the same time the effect of the variable pressure on the artery is measured at a second point, the second point being located farther away from the...

The present invention relates to an arrangement and method for providing wireless data communication services, between a client station (10) and a service providing station (15) and/or a computer network (13, 33), each of the client station (12), service providing station (15) or the computer network (13, 33) being connected to at least one radio transceiver (11, 12) and each being arranged with m...

The invention relates to a data transmission method between a network part of a General Packet Radio Service and a subscriber terminal. In the method an RLC/MAC (Radio Link Control/Medium Access Control) protocol layer and an LLC (Logical Link Control) protocol layer employing the services of the RLC/MAC protocol layer are used as data link layers. In data transmission an LLC frame of the LLC laye...

Acid-resistant, non-rusting pins (B) are pushed down to a pre-determined level into each individual cell in an existing battery (A), or they can be cast into a new battery during the manufacturing process. The pins are each connected to cables (D) that are combined to form a trunk cable (G) leading to a coupling box (F), which is linked via a further cable (G) to a display (H) with light diodes th...

Arrangement 1 for presentation of three-dimensional graphics comprises means of defining one or more polygons from an object being presented; a means 2, 3, 4 for mapping the relief, comprising a means 6 for storing the relief map and a means 5 for fetching the relief map from the means 6 for storing of the relief map; and means of defining the normal directional vectors of the relief map at each v...

Along the longitudinal edge of the support sheet is adhered a group smooth strips rectangular in cross-section and sharp-edged. These strips are spaced part by a distance of less than approximately 3mm. A corresponding band-form protective sheet is adhered to the sides of the strips opposite to the support sheet. On these sides an adhesive is provided for fixture to the windscreens. After the pro...

Sludge is fed through a conically tapered feed device into a concentric arrangement of an inner tube and outer perforated tube with a retainer at the downstream end. An arrangement for dewatering sludge and fibrous material includes a feed device (1) for delivering the sludge to a device (2) where water is separated. A fixed outer cylindrical tube (3) is present, containing slots in its wall (4) ...
