Abstract: Blood sugar levels are measured non-invasively based on temperature measurement. Non-invasively measured blood sugar level values obtained by a temperature measurement scheme are corrected by blood oxygen saturation and blood flow volume, thereby stabilizing the measurement data. A guide is provided for guiding an analyte to a measurement portion.

Abstract: Body-surface temperatures are measured in order to obtain information about the dissipation of heat from a body surface and information about blood flow volume. Certain parameters are calculated from the measured temperatures, blood flow volume, and constants related to hemoglobin concentration and hemoglobin oxygen saturation. The parameters are applied to a relationship between predetermined parameters and blood sugar levels to obtain a blood sugar level.

Abstract: Blood sugar levels are measured in a non-invasive way based on temperature measurement. Different regression functions are used for an able-bodied person and a diabetic patient when stabilizing measurement data by correcting a non-invasively measured blood sugar level, i.e. a value obtained by temperature measurement, with blood oxygen saturation and blood flow volume.

Abstract: In a method and apparatus for determining the blood glucose concentration reliably and accurately based on temperature data obtained from a subject without requiring blood sampling, chronological changes in the output from a temperature detecting portion are monitored. Based on those chronological changes, the making of contact between a body surface and a body surface contact portion is detected, whereupon the acquisition of measurement data is started and an advance-notice display about the timing of departure of the body surface is made. The moment of departure of the body surface from the body surface contact portion is detected, and if that moment is before the noticed timing, or in the absence of detection of the departure of the body surface from the body surface contact portion even after a certain time following the noticed timing, an error display is made on the apparatus and the measurement is reset.

Abstract: Blood sugar levels are measured non-invasively based on temperature measurement. Values of blood sugar levels non-invasively measured by a temperature measuring system are corrected using blood oxygen saturation and blood flow volume. Optical sensors are provided for detecting scattered light, reflected light, and light that enters into the skin which travels out of the body surface. The measurement data is stabilized by taking into consideration the influence of the thickness of skin on blood oxygen saturation.

Abstract: Blood sugar levels are non-invasively measured based on temperature measurements. An insulation structure is employed in a temperature measurement part for measuring heat amount and non-invasively obtained blood sugar level measurements are corrected by blood oxygen saturation and the volume of blood flow so that the measurement data can be stabilized and the measurement accuracy can be enhanced.

Abstract: Blood sugar levels are measured non-invasively based on temperature measurement. Measured blood sugar levels are corrected using blood oxygen saturation and blood flow volume. The measurement data is further stabilized by taking into consideration the influences of interfering substances on blood oxygen saturation.

Abstract: Disclosed is an operational-temperature-stabilized wavelength-stabilized laser diode having an integrated temperature control unit. Such diode arrangement has combinations of the following features: at least one laser chip; heating provided by at least one PTC resistor such that a device operational temperature is controlled by this PTC resistor; a detector for determining the radiation emerging from the rear of the laser chip; an NTC resistor or a thermo-element for measuring the chip temperature. The laser chip serves a dual function of acting as a laser source and as a radiation detector, thereby eliminating any need for a separately provided radiation detector and resulting in a compact device. All the components required for temperature control, respectively, temperature stabilization, are miniaturized and integrated with the laser chip within a housing. The extremely small size of the invented laser diode opens a wide range of possible applications.
