摘要:
The invention concerns a device (1) for the inhalation of at least one drug from a gas canister (98) having a nozzle (96) by a person suffering from asthma or bronchospasm, the device comprising a gas container (10) having at least one wall (12), the wall surrounding a gas containment chamber (14) adapted to contain gas at a pressure larger than atmospheric pressure, the gas container (10) further having an inlet (16) adapted for connection to the nozzle (96) of the gas canister (98), the gas container (10) further having an outlet (18) with an outlet valve (20) adapted to allow the person to inhale gas from the device through the outlet; wherein the outlet valve (20) is adapted to be activated by the inhalation of the person independent of the activation of the gas canister (98). This invention allows the person to activate the gas canister, and pause before inhalation. The invention is adapted to facilitate coordination for the patient inhaling.

The aerosol inhalation device is manually operated and comprises a holding part (3) for receiving an aerosol container with a valve and an outlet tip, and an inspiratory part (1), which at one end comprises a mouthpiece (2), in which inspiratory part (1) a member (4) for passage of aerosol is provided for receiving the outlet end of the aerosol container and comprising a conduit (5) with an outlet opening for discharging aerosol into the inspiratory part in the direction towards the mouthpiece (2). At the end opposite the mouthpiece (2) the inspiratory part (1) is open towards the surroundings such that air may pass freely from the surroundings past the member (4) for passage of aerosol and out through the mouthpiece (2).

Design optimization methods can be used to design concrete mixtures having optimized properties, including desired strength and slump at minimal cost. The design optimization methods use a computer-implemented process that is able to design and virtually “test” millions of hypothetical concrete compositions using mathematical algorithms that interrelate a number of variables that affect strength, slump, cost and other desired features. The design optimization procedure utilizes a constant K (or K factor) within Feret's strength equation that varies (e.g., logarithmically) with concrete strength for any given set of raw material inputs and processing equipment. That means that the binding efficiency or effectiveness of hydraulic cement increases with increasing concentration so long as the concrete remains optimized. The knowledge of how the K factor varies with binding efficiency and strength is a powerful tool that can be applied in multiple circumstances. A concrete manufacturing process may include accurately measuring the raw materials to minimize variation between predicted and actual strength, as well as carefully controlling water content throughout the manufacturing and delivery process.

This invention relates to a pressure sensor comprising a diaphragm and at least one measuring element, which is situated on the diaphragm while serving to measure a deflection of the diaphragm. A holding element is placed on at least one surface of the diaphragm in order to accommodate a seal element, whereby this holding element has a through hole, which faces the diaphragm surface while having a cross-section that corresponds to the outer contour of a seal element to be accommodated.

The present invention relates to a credit card comprising a card body, which comprises fingerprint reading means providing fingerprint signals representative of at least one fingerprint from a card user, when at least one finger of said user is pressed against said fingerprint reading means. Said card body further comprises data carrier means holding at least card owner fingerprint data and secured data, and fingerprint authentication means for activating said secured data. The card body further comprises an electrical power supply delivering electrical current to at least said fingerprint reading means. Accordingly, there is no need for an external electrical power supply, and thus the existing standard card reading systems, such as ID-card readers, money transfer machines such as ATM's and the like may be used in conjunction with said credit card. Thus, investments into new standard reader systems are not necessary in order to improve the security of the secured data carried by the credit card. A complete and self-contained automated authentication process is conducted prior to communication concerning said secured data being established between said credit card and any of the existing ATM's on the market today, irrespective of type (automated or manually operated), manufacturer, version, or geographical position of said ATM and of credit card use.

A covering plate (5), for flooring in conveyances such as a railway car, is provided with a securing track (11) for securing seats, etc. The covering plate (5) is formed by a sandwich structure having a central core (24) arranged between an outer plate (25), which extends across the entire size of the covering plate, and second outer plates (26). The securing track (11) is formed in a profile (27) embedded in the sandwich structure so that a securing track (11) extends at a right angle to lateral edges (14) of the covering plate (5). As either end of the profile is provided with tracks (29) for receiving tight-fitting pins (30), a floor structure can be mounted easily and rapidly.
