Abstract: The present invention relates to a method and a system for carrying out the method of determining at least one cardiovascular quantity of a mammal. The method comprises (i) selecting a measuring site of a vessel; (ii) determining or estimating a mean diameter of the vessel at the measuring site; (iii) determining a pulse wave velocity and/or another elasticity related quantity of the vessel at the measuring site; (iv) determining a distension of the vessel at the measuring site; and (v) calculating the at least one cardiovascular quantity from the determined mean diameter, elasticity related quantity and distension of the vessel at the measuring site.

Abstract: A dressing is provided for application to an object that is, at least partly, electrically conductive. The dressing includes an adhesive for attaching the dressing to the object, and at least two electrodes. The electrodes are adapted to be arranged at a distance from the partly electrically conductive object so that a first capacitor is formed between a first electrode and the partly electrically conductive object, and a second capacitor is formed between a second electrode and the partly electrically conductive object.

Abstract: The present invention relates to a method and dressing for detecting detachment of the dressing, which is applied to a surface of an at least partly electrically conductive object. The dressing comprises an adhesive for attaching the dressing to the electrically conductive object and at least two electrodes arranged in a distance from the electrically conductive object. A voltage is applied to the first and second electrode establishing an electrical circuit comprising a first capacitor between the first electrode and the electrically conductive object and a second capacitor between the second electrode and the electrically conductive object. Changes of the capacitance between at least one of the first and the second electrode and the electrically conductive object are detected, and an alarm is activated when the changes of the capacitance reach a predetermined value. This advantageously provides a method whereby a leak can be detected quickly.

Abstract: The present disclosure relates to methods, apparatus and sensor for measurement of cardiovascular quantities. In particular, a method for determining one or more cardiovascular quantities is disclosed, the method comprising determining the distension of a vessel enclosed by tissue having a skin surface, wherein determining the distension is based on a first sensor signal indicating capacitance variations between a first electrode and a second electrode; determining the vascular stiffness of the vessel; and determining the blood pressure based on the distension and the vascular stiffness of the vessel.

Abstract: A sensor system for measuring the blood pressure in such a way that the sensing position is in a correct position relative to the heart is devised. The system consists of a wireless sensing device, a transceiver, and a computing and recording device. The sensor reading is recorded wirelessly. The sensor is placed at a convenient location on the body. The coupling antennas are designed in such a way that the antenna characteristics ensures that only when the sensors is within a predetermined position relative to the heart will a recording of the blood pressure actually take place.

Abstract: The present invention relates to a method and an apparatus for non-interfering blood pressure measurements. In particular, the invention relates to an apparatus for continuously monitoring blood pressure for patients at home or at work. The apparatus comprises an extra-corporal sensor for blood pressure determination with a flexible housing adapted to be attached to the body of a living being proximate to an artery, and an electronic circuit for wireless coupling to a remote transceiver in accordance with the blood pressure in the artery, the remote transceiver adapted for wireless coupling to the sensor for generation of a pressure signal in accordance with the blood pressure in the artery, and a processor connected to the remote transceiver for reception of the pressure signal and adapted to estimate systolic and diastolic pressure based on the signal.

Abstract: A sensitive refractive index based detector comprises a first laser cavity (7) and a second laser cavity (7′) each for generating a respective laser light beam. Each laser cavity is defined in a planar waveguide. The surface of the waveguide of the first laser (7) receives a sample to be detected. Light from the two lasers is mixed using a coupling grating (3) and a beat frequency between the lasers dependent upon the refractive index of the substance is measured at a detector (4). Extremely sensitive measurement of small quantities of substance are made possible.

Abstract: A method and an apparatus are provided for the determination of a condition or state of an object based on quasi-elastic interaction between the object and light transmitted to the object. This light is transmitted from a light source through a diffractive optical element. The light that has interacted with the object is collected and detected. The diffractive optical element is designed in such a way that the determination of the condition or state of the object is substantially exclusively defined by the diffractive optical element and substantially independent of properties of the light source. Several diffraction patterns may be integrated in one diffractive optical element, thereby integrating several optical functions, such as lenses, beam splitters, etc. in one optical component. Use: Transit-time-velocity measurement, Doppler velocity measurement, viscoelastic measurement, differential speckle determination, differential vibrometer, distance determination apparatus, etc.

Abstract: A wind turbine includes a laser wind velocity measurement system mounted on a nacelle of the wind turbine for determination of air velocities at the same relative position in front of the wind turbine, and which compensates for wind velocity changes prior to impingement of the air flow on the adjustable pitch wind turbine blades so that desired maximum tip speeds, tip speed ratios, and normalized power output Cp may be maintained.
