6787 results about "Thermometer" patented technology

A thermometer is a device that measures temperature or a temperature gradient. A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value (e.g. the visible scale that is marked on a mercury-in-glass thermometer or the digital readout on an infrared model). Thermometers are widely used in technology and industry to monitor processes, in meteorology, in medicine, and in scientific research.

Method and apparatus including altimeter and accelerometers for determining work performed by an individual

Method and calculations determine an individual's, or several individuals' simultaneous rates of oxygen consumption, maximum rates of oxygen consumption, heart rates, calorie expenditures, and METS (multiples of metabolic resting rate) in order to determine the amounts of work that is performed by the individual's body. A heart monitor measures the heart rate, and an accelerometer measures the acceleration of the body along one or more axes. An altimeter measures change in altitude, a glucose monitor measures glucose in tissue and blood, and thermometers, thermistors, or thermocouples measure body temperature. Data including body fat and blood pressure measurements are stored locally and transferred to a processor for calculation of the rate of physiological energy expenditure. Certain cardiovascular parameters are mathematically determined. Comparison of each axis response to the individual's moment can be used to identify the type of activity performed and the information may be used to accurately calculate total energy expenditure for each physical activity. Energy expenditure may be calculated by assigning a separate proportionality coefficient to each axis and tabulating the resulting filtered dynamic acceleration over time, or by comparison with previously predetermined expenditures for each activity type. A comparison of total energy expenditure from the current activity is compared with expenditure from a previous activity, or with a baseline expenditure rate to assess the level of current expenditure. A measure of the individual's cardio-vascular health may be obtained by monitoring the heart's responses to various types of activity and to total energy expended.

Temperature measuring system, heating device using it and production method for semiconductor wafer, heat ray insulating translucent member, visible light reflection membner, exposure system-use reflection mirror and exposure system, and semiconductor device produced by using them and vetical heat treating device

Oppositely of a temperature measuring surface of an object-to-be-measured 16, a reflecting member 28 is disposed while being spaced by a reflection gap 35 from the temperature measuring surface. The reflecting member 28 is composed of a heat ray reflecting material capable of reflecting heat ray in a specific wavelength band, in a portion including a reflection surface 35a. A heat ray extraction pathway section 30 is disposed through the reflecting member 28 so that one end thereof faces the temperature measuring surface. Heat ray extracted through the heat ray extraction pathway section from the reflection gap is detected by a temperature detection section 34. The heat ray reflecting material is configured in a form of a stack comprising a plurality of element reflecting layers composed of a material having transparent properties to the heat ray, in which every adjacent two element reflecting layers are composed of a combination of materials having refractive indices which differ from each other by 1.1 or more. This makes the measurement be hardly affected by radiation ratio of the object-to-be-measured when temperature of the object-to-be-measured is measured by a radiation thermometer, enables to measure its temperature more correctly irrespective of the surface state thereof, and can simplify configuration of a measurement system.
