摘要:
In a method an apparatus for vaporizing anesthetic liquids, in which a carrier gas is passed through a vaporizer so as to be saturated with vaporized anesthetic liquid, the vaporizer has a container, partially filled with anesthetic liquid, an inlet for a carrier gas, an outlet for carrier gas saturated with anesthetic and a pressure chamber. The carrier gas is supplied to the vaporizer at a pressure exceeding atmospheric pressure and is bubbled through the anesthetic liquid in the container in order to become saturated with anesthetic. The flow of gas at the outlet can be regulated as needed. Exact pressure and temperature conditions can be measured and/or regulated with a pressure meter, pressure regulator, thermometer and temperature regulator in order to regulate the partial pressure of anesthetic in the container.

In conjunction with the diagnosis of conditions in and treatment of the lungs, a small amount of NO is supplied to the lungs in some cases. A gas mixture for this purpose is disclosed in which an inert, non-toxic trace gas is present in an exact concentration in relation to NO, in order to simply and safely control the amount of NO then supplied to the lungs. The amount of NO supplied can be determined by determining the concentration of the trace gas. A method and device for administering breathing gas to a patient together with the aforementioned gas mixture are also disclosed.

A method and apparatus for independent monitoring of a flow-through quantity and, potentially, of a concentration of a gas flow that is extremely small in comparison to a respiratory gas flow is provided. The valve for the control of this small gas flow can not be controlled via the overall gas flow. In order to be able to simply and reliably monitor the flow-through quantity and the concentration of this small gas flow without a gas analyzer and independently of gas flow regulators that are usually present, it is provided that the small gas flow be separately measured and compared to a value derived from the respiratory gas flow. Given the presence of prescribable criteria, an alarm is triggered and the flow-through quantity of the small gas flow is, for example, interrupted.

A inventory information system having an inventory station having an array of unique locations defined thereon; a plurality of indicators, each of the indicators being associated with each of the locations; a plurality of tags, each of the tags having an identifier associated therewith; at least one detector operable to obtain identifier associated with one of the tags when the tag is positioned at one of the locations; and a processor operatively coupled to the at least one detector and the plurality of indicators. The processor is configured to receive the identifier and to determine an inventory status of at least one product associated with the identifier, and operate the indicator associated the location where the tag based upon the inventory status to provide information about the inventory status.

The invention relates to a method of producing a movable lens structure that comprises the steps of: forming a lens from a lens material disposed on a carrier of another material (step 58), and forming a micromechanical structure from the carrier (step 60), wherein the forming of the lens takes place before the forming of the micromechanical structure. With this method a simplified production method is obtained that simplifies difficult compatibility requirements between micromechanics and lens that can otherwise be hard to meet.

Radio channel resources are allocated in a radio communications system based on whether a requested data communication requested is associated with a symmetric service or an asymmetric service. If the data communication is associated with a symmetric service, a symmetric connection between the mobile radio station and the radio network is established for communicating data packets associated with the data communication. Radio channel resources are assigned to the symmetric connection for transporting the data packets between the mobile radio station and the radio network. The symmetric connection is assigned substantially the same amount of radio channel resources in an uplink direction as in a downlink direction. In one example, the symmetric data communication is a voice over IP (VoIP) communication. One example environment is a GPRS/EDGE type system where the radio channel resources are time slots and the symmetric connection includes an uplink temporary block flow (TBF) and a downlink TBF.

The present invention relates to method of manufacturing a sulphonate-functionalized (S-functionalized) cation exchanger, which method comprises reacting olefinic groups with bisulphite in the presence of at least one amine oxide, such as N-methyl morpholine oxide (NMO). The olefinic groups of the carrier may be allyl groups; which may be provided on extenders such as polyhydroxyfunctional polymers. In one embodiment, the carrier is made of agarose with improved flow pressure properties.

A method is provided for controlling a drive arrangement in a watercraft. The method includes detecting thrust and steering commands from an operating device which is connected to a control unit, and controlling the drive arrangement based on detected commands from the operating device for obtaining a desired course of travel of the watercraft, wherein a force is generated which acts towards a defined position on the watercraft. The method furthermore includes determining the speed of the watercraft and adapting the position on which the force from the drive arrangement acts as a function of at least the speed and as a function of the influence of the position of the center of pressure of the watercraft, thereby maintaining the desired course of travel. An arrangement for controlling a drive arrangement in a watercraft is also provided.
