Abstract: Electric power is provided to motor vehicles via a respective outlet station. A number of outlet stations are connected to a common electric power supply, each with an interface towards a control node. Over the interfaces, the outlet stations receive operation commands from and send status messages to the control node. The control node allocates a fraction of the common electric power supply to each outlet station to which a motor vehicle is connected. The fractions are allocated such that a sum of all fractions represent a total delivered power, which is less than or equal to a predefined maximum level for the common electric power supply. If an interface between an outlet station and the control node is broken, the outlet station is configured to apply a power supply scheme according to which the outlet station is only allowed to deliver electric power up to a level prescribed by a predefined principle stored in each of the outlet stations.

Abstract: A utility is distributed to a group of subscribers via a distribution network. At least one parameter reflecting an instantaneous overall consumption of the utility in the distribution network is measured repeatedly, and an amount of the utility delivered to each subscriber in the group is controlled in response thereto. It is checked whether the instantaneous overall consumption of the utility is within an acceptable interval. If it is below a lower threshold level, at least one load is controlled to increase its consumption of the utility according to a pre-defined scheme in proportion to a deviation of the instantaneous overall consumption of the utility from the lower threshold level. If it is above an upper threshold level, at least one load is controlled to decrease its consumption of the utility according to the pre-defined scheme in proportion to a deviation of the overall consumption of the utility from the upper threshold level.

Abstract: The invention relates to a flexible fitting solution for a portable device for inputting control signals to a peripheral unit, which includes a holding member designed to be attached to a hand of a user of the device so as to retain the device in a predetermined manner on the hand. The holding member comprises at least one elongated portion and at least one curved portion connected thereto. A side of the holding member that faces the user's hand when the device is attached to the hand includes a padding module. The padding module, in turn, includes at least one pad cushion adapted to fit the device to the user's hand. The padding module is removably fastened to the holding member by means of a set of fastening members, which secure the padding module in a fastened position. By selecting an appropriate padding module, each user of the device may obtain a good fit of the device onto his/her hand.

With the help of the input members of the device, essentially all the basic symbols of a standard computer keyboard can be generated. The invention also concerns the use of such a device.

Abstract: A primary pointing device controls the position of a cursor on a digital screen by means of primary position commands (C1). The primary position commands (C1) are generated by relative movement (D11; D12) between the primary pointing device and a substantially flat external surface, such as a tabletop or mouse pad. The primary pointing device is adapted to dock with a secondary pointing device, which may also control the position of the cursor on the digital screen. Bearing registering user input controls in the secondary pointing device generate secondary position commands (C2), which are fed to the digital processor for causing the cursor to move on the digital screen. Furthermore, the primary pointing device is adapted to dock with the secondary pointing device.

Abstract: In a method for determining the elastic volume (representing the gas which must be added to compensate for the compression of gas occurring in the tubing system) of a tubing system connected to a patient without the patient's lungs and airways entering into the determination, a determination of the volume of the tubing system is made at two different pressures during one breathing cycle and the elastic volume is calculated from the volumes thus determined. The volume of the tubing system can be established by adding a predetermined flow of a first gas to the tubing system, while constant pressure is maintained in the tubing system, when the flow of breathing gas to/from the patient is virtually zero, determining when the first gas starts flowing out of the tubing system and determining the volume of the added first gas, this volume constituting the volume of the tubing system.

Abstract: A ventilator system has at least one ventilator unit and a number of docking stations is described. Each docking station is adapted to receive the ventilator unit and comprises a communication interface adapted to be connected to a matching interface on the ventilator unit when the ventilator unit is docked in the docking station. The docking stations are arranged at different treatment sites, and the ventilator unit can be moved between different docking stations when necessary without interrupting the treatment of a patient connected to the ventilator unit. The same ventilator unit can be used throughout a complete treatment of a patient without any need of disconnecting the patient during transports, etc.

Abstract: In respiratory care with liquids, the patient is connected to a liquid apparatus and a ventilator for supplying and removing a treatment liquid and a breathing gas respectively to/from the patient. The exchange of gases between the breathing gas and the treatment liquid is improved with a device which causes the breathing gas and/or the liquid to oscillate. The device may be a breathing gas generator which generates different frequencies to cause the breathing gas and treatment liquid to oscillate at appropriate frequencies. The device may be a vibrator unit which is applied to the chest to cause the treatment liquid to oscillate. The device may be a magnetic field generator for generating a magnetic field across the lungs and setting electrically conductive components in the treatment liquid in motion.

Abstract: A portable respiration apparatus is dimensioned to convey a flow of gas, with an upper limit on pressure, from an inlet to an outlet connected to a patient. The inlet of the portable respiration apparatus can be connected to a stationary gas unit when a higher pressure is desired. The stationary gas unit can generate a gas pressure that is applied to the inlet of the portable respiration apparatus, so that a higher gas pressure can be generated and delivered to the patient. Alternatively, the stationary gas unit can be dimensioned so that it is itself capable of generating the desired gas pressure to be supplied to the patient, so there is no additional increase in gas pressure in the portable respiration apparatus.

Abstract: A heart stimulator, with verification of capture in the atrium of a heart, contains an atrial pulse generator which, via an atrial electrode, emits stimulation pulses in the atrium and a ventricular detector which senses depolarization signals in the ventricle via a ventricular electrode. The time which elapses between two consecutive stimulation pulses emitted in the atrium can be varied, and variation in ventricular events associated with the stimulation pulses is studied. If the ventricular events vary in time in the same way stimulation pulses emitted in the atrium vary, AV conduction is functional, and capture is present in the atrium.

Abstract: A ventilator system and a tracheal tube, inserted into a patient's trachea to carry gas to and from the lungs, permit a gas mixture containing endogenous NO, which is present in the upper respiratory tract, to be supplied to the lungs. The tracheal tube has a input port which forms a connection between the interior of the tracheal tube and the upper respiratory tract. The input port draws or forces an amount of the gas containing endogenous NO into the tracheal tube and this gas accompanies the respiratory gas into the lungs during inspiration.
