Abstract: A sphygmomanometer includes a compression cuff (11) for pressing the artery of an object to be examined, a measurement cuff (12) formed inside the compression cuff (11) and set in close contact with a portion to be measured to detect a oscillation of the artery wall caused by arterial pulsation when the cuff pressure changes, and a pressure sensor (16) for measuring the pressure of the measurement cuff (12). This sphygmomanometer detects peaks of the oscillation from a oscillation signal detected by the measurement cuff (12), and determines the systolic blood pressure by using a plurality of pieces of peak information detected. To prevent the transmission of oscillations from the compression cuff (11) to the measurement cuff (12), a cuff of this invention includes, on the contact surface between the measurement cuff and the compression cuff, a cushioning material formed on the side of the compression cuff to absorb oscillations, and a rigid body formed on the side of the measurement cuff to reflect oscillations. An air chamber (damper cuff) (15) and a tubule (14) are formed in a connecting portion between the measurement cuff and the compression cuff. A cushioning material (13) is placed on that contact surface between the compression cuff and a portion to be measured, which is in a blood vessel upstream portion of the measurement cuff. <IMAGE>

Abstract: A mounting arrangement for a propeller device (8), e.g. a transverse propeller, which is disposed in a channel (4) of a vessel's hull (2). The propeller device (8) comprises a tubular casing (10) and a propeller (12), which is rotatably mounted in the casing (10). Between the casing (10) and the channel (4) there is created an annulus (22), wherein there are mounted resilient air containers (30, 32) for elastic, vibration-damping mounting of the casing (10) in the channel (4).At each end of the annulus (22) there is mounted an air container (30,32), which extends round the casing (10) and seals the annulus (22). A compressed air source (50) is connected to the respective air containers (30, 32) via controllable valves (60, 62). Furthermore, a sensor (80) for measuring the channel's (4) vibration and a sensor (20) for measuring the propeller's rotational frequency are provided. By controlling the valves (60, 62) the air containers' (30, 32) spring stiffness can be controlled for minimising the vibration that is transmitted from the casing (10) to the channel (4) during the propeller device's (8) operation.

Abstract: The band comprises a carrier strip(1) on the upper side and an adhesive coating(2) on the band underside covered by a removable protective film(3). The band is folded in the transverse direction along a first edge(5) running along the band length so that at least part of the adhesive coating remains uncovered by the protective film. In one form the adhesive coating(2) may remain uncovered by protective film(3) at least in the area of the first folded section(4). In an alternative the band has a second folded section folded over in the transverse direction along a second folding edge running along the band length. The protective film(3) may have a longitudinal slit which may or may not coincide with the second folding edge. An edge(9) of the protective film projects beyond the first(5) and/or second folding edge. The adhesive coating may remain uncovered in the area of the second folded section First and second folded sections may be the opposing edges of the band and free ends of both sections are adjacent to each other. Alternatively the first and second sections are folded so that one lies on top of the other. In this case the band upper side may lie on top of each other or band undersides may lie on top of each other. The carrier layer(1) can be torn by hand transverse to the band length. When folded the band is formed into a roll. In the non-folded condition the band is not less than3cm, preferably 3-50cm, more preferably 4-30cm and even more preferably 4.5-20cm wide. Areas of the band may be perforated, the perforations having an average size of 3mm and a round, rectangular or oval shape. Carrier material provides good adhesion to mortar.
