Abstract: In order to improve the use of a medical support and compression stocking, it is proposed that the stocking (10) shall comprise a woven- or knitted-fabric-type base element (20) that is substantially tubular and that can be pulled over the lower leg of the wearer. Moreover, the stocking comprises at least one air chamber (30) that can be filled with air. The air chamber (30) is designed in a tubular shape along the length of the support and compression stocking. The stocking further comprises an electronic unit that is equipped with a micropump and a valve for the air supply, the micropump being provided with a valve, a current source, preferably a rechargeable battery and control electronics including a wireless data transfer unit. The pressure values of the at least one air chamber can be regulated by means of the data transfer unit and a software stored in the electronic unit.

Abstract: The inventive fitness device is embodied in the form of an article of clothing, consisting of a pair of trousers, for example, consisting of an airtight outer skin (1) made of an elastic plastic material, and a distancing layer (2) which is arranged thereunder and made of a distancing knitted fabric consisting of monofilament fibres. Sealing edges (6) are produced by wrapping the outer skin (1) over the distancing layer (2). A vacuum tube (4) can be connected to a connection piece (3). A portable vacuum pump (5) produces a medically and advantageously indexed negative differential pressure in relation to atmospheric pressure, which extends into the entire article of clothing as a result of the distancing layer (2). The vacuum pump (5) is fastened to a strip (7) which can be worn on the shoulders or in an otherwise appropriate position.

Abstract: Disclosed is an anti-buckling device (1) which is made of an elastic material and comprises several ribs (2) that extend in the longitudinal direction thereof, the space between two ribs (2) forming a groove (3). The anti-buckling device (1) is inserted into a thin-walled duct. The anti-buckling device (1) prevents the duct from buckling and thus from being occluded in a bend when said duct is bent. A fluid is able to circulate within the duct and bypass the bend in the grooves (3) of the anti-buckling device (1). The envelope of the cross section of the anti-buckling device is essentially lenticular as a duct having a round cross section also becomes lenticular in a bend.

Abstract: The invention relates to a device for protecting pilots and other crew members of high-performance aircrafts, especially people wearing pressure suits (1) according to the hydrostatic principle with veins (6) filled with liquid. Said device consists of a tension pocket (2) located in the region of the back and a pressure pocket (3) located in the abdominal region, airtight bladders (4) being inserted into both pockets. Said bladders (4) contain woven spacer elements (5) defining a minimum air volume in the bladders (4). In the event of falling ambient pressure, the pressure pocket (3) first expands and supports the breathing of the person wearing the device by means of pressure on the viscera, when pressure respiration appliances are used. If the ambient pressure falls further, the tension pocket (2) inflates and increases the peripheral tension in the pressure suit (1). In this way, for example, a decompression syndrome can be counteracted in the event of a sudden pressure drop in the cabin at high altitude.

Abstract: The invention relates to a modular data recording and display unit. A module (4) essentially comprises a sensor (5), a controller (10) and a memory (11). The controller (10) processed the data recorded and transmitted by the sensor (5) and records the same in the memory (11). One or several types of sensors (5) may be connected depending on the module (4), for example with differing measuring ranges or differing measuring parameters. The multiplicity of connection possibilities and data formats can make the provision of further components, such as transmitter (6), receiver (7), amplifier (8) and converter (9) necessary between a sensor (5) and a controller (10). The controller (10) for the module (4) is configured and controlled by means of a control bus (12). The measured data stored in the memory (11) are read off using a separate data bus (13).

Abstract: An altitude protection device for an acceleration protection suit having a plurality of liquid-filled veins is comprised of a bladder inserted in a pocket. A spacer fabric that is non-compressible under the loads to be provided is enclosed in the pocket and defines a minimum volume inside the bladder. The bladder is closed off or opened relative to surrounding air in the aircraft cabin via a valve that is opened if a rate of pressure change in the cabin is less than or equal to a presettable maximum value, and closed if the rate of pressure change is greater than the value. If the valve closes and the pressure falls further, air located in the bladder inflates the bladder and pocket, increasing tensile stress in the fabric, and thereby raising the internal pressure of the veins resulting in increased internal pressure in the entire acceleration protection suit.

Abstract: On an anti-blackout suit (1) operating according to the hydrostatic principle, a pressure measurement cell (3) is arranged at, for example, the lowest point of a liquid-conveying vein (2) which, by its internal pressure, generates the circulation stress required for the anti-blackout suit (1). Pressure changes arise as a result of the volume changes, during respiration, in the person wearing the anti-blackout suit (1), and these pressure changes are measured by the pressure measurement cell (3) and, for example, transmitted to an evaluation apparatus via a cable (5). Both a display device and also a memory device can be linked to the evaluation unit.

Abstract: The note board has a writing surface and a writing instrument accommodated in a holder. The writing surface is situated on a transparent recording substrate, under which a light source, serving as background illumination, is disposed. A solar panel and an accumulator supply the light source with electrical power. A reed switch is actuated by means of a permanent magnet disposed on the writing instrument in such a way that the light source is switched on as soon as the writing instrument is taken from the holder. The note board is completely watertight, so that it can be used underwater by divers.

Abstract: The active part of the suit comprises in part one layer (3, 4) facing the body and another one facing away from it, both of a gas-tight, low stretch textile material, which are joined together at connecting positions (6) by gluing, welding or sewing and thereby create hollow spaces (5), which are connected together via valves (18) and can be put under pressure. Between the regions, which comprise the layers (3, 4)—bands (11, 12)—connecting parts (7) are arranged, which transmit tensile forces only. If the hollow spaces (5) are put under a gas pressure proportional to the z-acceleration, then the suit builds up a compensating applied pressure and thus frees the organism of the pilot from the loading effects of such accelerations. By a suitable choice of the width of the bands (11, 12) in conjunction with the radius of the enclosed part of the body a compensating pressure to the hydrostatic pressure, proportional to the acceleration, of the body fluids can be set up.

Abstract: The suit according to the invention comprises, as well as a textile lining and an oversuit, an active part lying between them. This is at least partly made from a layer (3) on the body side and a layer (4) away from it, both of a fluid-tight, low stretch textile material, which are connected to each other at connection positions (6) by gluing, welding or sewing and thereby create hollow spaces (5), which are filled with fluid through valves (16, 17). Between regions, which comprise the layers (3, 4), for instance the upper part (14) and the front part (15), joining parts can be arranged, which transmit tensile forces only. This builds up a compensating pressure proportional to the acceleration working in the momentary and local direction on the parts of the body lying beneath and thus takes the load off the organism of the pilot arising from the effects of such accelerations.

Abstract: A diving computer has a housing in which electronic components, at least one diving data display means and an electricity source are disposed water-tightly. Furthermore there are means, accessible from the outside, for connecting the energy source to the electronic elements. The diving data display means is preferably a liquid crystal display module with an integrated background illumination that can be switched on and off. For switching on and off this said illumination, an acceleration sensor and an electronic circuit are mounted in the diving computer. These last-mentioned parts have the effect that the illumination can be switched on or off by merely knocking on the diving computer or hitting the latter against another object. This is a procedure which can also be done underwater easily and safely, using just one hand, despite relatively thick diving gloves.
