摘要： The invention relates to a method and an apparatus for non-dispersive analysis of gas mixtures for determining the concentration of such a first gas component in a gas mixture, whose absorbance may be influenced by other gas components of said gas mixture. The apparatus comprises a sample chamber (2) for containing the gas mixture, a radiation source (1) for transmitting radiation through the gas mixture, a first optical transmission band filter (5) with a first absorption transmission band of the first gas and a first radiation detector (4). The apparatus further comprises a sec-ond optical transmission band filter (8) with a second transmission band, which is outside the first transmission band, and a second detector (7). The concentration de-termining means (23) are arranged to determine the concentration of the first gas us-ing a certain formula or formulas and using the detected intensities. The second transmission band is substantially or entirely outside the absorption bands of said first gas component and comprises a second absorption band of a certain gas com-ponent causing a distortion in the absorption band of the first gas component, the strength of the second absorption band being substantially less than the strength of the first absorption band.

摘要： A system for selectively collecting location information in a tracking environment includes a first energy signal identification badge for detecting trigger signals and transmitting identification data signals indicating existence of a proximity condition between the first badge and a source of the trigger signals. The trigger source transmits trigger signals of a predetermined power level, wherein the first badge can detect the trigger signals only if the first badge is within a predetermined radius of the trigger source when the trigger source transmits the trigger signals. The first badge transmits the identification data signals when the first badge detects the trigger signals transmitted by the trigger source.

摘要： In one embodiment, EEG signal data entropy is determined (120) as an indication of the depth of anesthesia. A frequency domain power spectrum quantity (126) is obtained fom the patient's EMG signal data (124), which can be updated more frequently than the EEG entropy due to its higher frequency. The EEG entropy indication (122) and the EMG power of spectrum indication (126) can be combined into a composite indicator (128) that provides an immediate indication of patient state changes. In a further embodiment, a set of frequency components obtained from selected frequency ranges (406) is utilized in determining entropy. The patient signal data (400) from which the frequency components are extracted are obtained from time windows of differing lengths (402) so that the resulting entropy indication (410,412) will have optimally fast response times.

摘要： The invention seeks to provide a method and a system for identifying a dominant signal component in a biosignal including at least two signal components. A biosignal including a first signal component having a first frequency range and a second signal component having a second frequency range is obtained from a subject. First and second indicators are then determined, which characterize the probability distribution of a predefined property, such as frequency, of the biosignal on predetermined primary and auxiliary frequency bands, respectively. Based on the first and second indicators, the system detects which one of the first and second signal components is currently a dominant signal component in the biosignal. The knowledge of the dominant component may be utilized in different ways in different systems monitoring the state of the subject.

摘要： The invention relates to monitoring of pain-related responses in a patient in order to detect the level of pain experienced by the patient. At least one first measurement signal is acquired from the patient and at least one of the signals is transformed into a normalized signal having a predetermined value range. Based on the at least one normalized signal obtained in this way, a threshold condition is set and a rate at which at least one second measurement signal fulfills the threshold condition is monitored, wherein each of the at least one second measurement signal is derivable from a corresponding normalized signal and indicative of pain-related activity in the patient. The level of pain experienced by the patient depends on the rate monitored.

摘要： A tonometric device for use in hollow viscus tonometry and remote sensing of patient fluid parameters is disclosed. The device is capable of monitoring certain critical fluid properties of interest, such as oxygen gases and carbon dioxide gases in the wall tissue itself of the patient's organ, rather than monitoring such properties in a lumen of the organ. A walled sampling chamber, which is preferably an inflated balloon member, is provided on an elongated tube, with provisions for positioning the sampling chamber in direct contact with a wall portion of the patient's internal organ.

摘要： An apparatus (1) for separating a liquid component from the exhalation gas of a patient to be delivered to one or more analyzing units (3, 4). The apparatus comprises a first chamber (10) for receiving therein an exhalation gas coming from a patient and in which the inflowing gas divides into two components in a manner that some of the gas flows to an analyzing unit and some of the gas, as well as a liquid component possibly entrapped in the exhalation gas, is conducted out past the analyzing unit, a second chamber (12), through which a patient's exhalation gas flows from the first chamber to an analyzing unit, and a gas-permeable wall (11), which separates these chambers and through which the gas flows from the first chamber into the second chamber. Upstream of the wall (11) there is a filter (20), the exhalation gas of a patient flowing through this filter prior penetrating through the wall (11) and the filter (20) allowing therethrough the flow of a liquid component possibly entrapped in the gas.

摘要： The invention relates to an automatic identification method for the cuff of a sphygmomanometer. When changing the pressure in a cuff (6 or 19) or in a space in flow communication therewith, the pressure change occurring in this space is monitored at two spaced-apart measuring points by means of one or a plurality of pressure-sensing means (12 and/or 9) and the pressure signals obtained from these two measuring points are compared to each other and, on the basis of the conducted comparison, the different cuff types are distinguished from each other as the measured pressure difference indicates a cuff type presently in use.

摘要： A method of nuclear magnetic resonance investigation of a repeated electromagnetic event in a sample comprises modulation of the nuclear spin polarization achieved during the recovery period between the final magnetic resonance signal detection period of one cycle and the initial signal generation RF pulse of the next cycle. This modulation is performed by giving the sample a different exposure to RF radiation in the different periods, for example by exposure to a different number of 180.degree. pulses in each period or by exposure to a frequency modulated continuous wave RF signal.
