摘要:
The invention relates to a device and method for measuring the properties of a surface. The device comprises means for producing illuminating light, which means are arranged to aim the illuminating light at the surface to be measured using at least two different wavelengths and at least two different angles, as well as means for directing the light reflected or scattered from the surface to a detector, in order to create an image of the surface to be measured. The device according to the invention further comprises at least one reference surface, the contents of which can be placed in the vicinity of the surface to be measured, in such a way that the illuminating light is also aimed at the reference surface and the light reflected or scattered from the reference surface can also be directed to the detector. The invention makes possible excellent measurement precision and repeatability, using a simple device construction with low production costs.

This document presents a wireless communication scheme utilizing a combination of two wireless communication schemes: a short range communication scheme and a radio communication scheme having a longer wireless transmission range than the wireless transmission range of the short range communication scheme. A short range signal is used to indicate a radio resource to be used for transmitting a radio signal, and the radio signal is then communicated in the radio resource indicated by the short range signal.

The invention relates to a measuring arrangement for measuring a pressure signal from a living body. The measuring arrangement comprises a sensor structure comprising a converter for converting the effect of the pressure signal measured from the body into an electrical signal. The measuring arrangement of the invention comprises a pressure transmission structure prior to the converter in the sensor structure, the pressure transmission structure comprising one or more pressure transmission elements. The pressure transmission structure is, through one or more pressure transmission elements, meant to be in direct or indirect contact with the body for detecting the pressure signal measurable from the body. The pressure transmission structure is, through one or more pressure transmission elements, connected to the converter for transmitting the effect of the pressure signal detected in the body to the converter in the sensor structure by means of one or more pressure transmission elements of the pressure transmission structure.

The invention relates to a method and an apparatus for identifying a heartbeat. In the method, an arterial pressure signal is measured in the form of multichannel measurement, and the required signal-processing operations, such as filtration, are carried out if necessary. The method also comprises carrying out signal detection and decision-making concerning the acceptance as a heartbeat signal. According to the invention, the signal detection includes multichannel channel-specific detection for the purpose of identifying signal components of different channels, and the obtained channel-specific detected channel signals are used as input data during the decision-making stage.
