Devices and corresponding methods can be provided to monitor or measure temperature of a target or to control a process. Targets can have low, unknown, or variable emissivity. Devices and corresponding methods can be used to measure temperatures of thin film, partially transparent, or opaque targets, as well as targets not filling a sensor's field of view. Temperature measurements can be made independent of emissivity of a target surface by, for example, inserting a target between a thermopile sensor and a background surface maintained at substantially the same temperature as the thermopile sensor. In embodiment devices and methods, a sensor temperature can be controlled to match a target temperature by minimizing or zeroing a net heat flux at the sensor, as derived from a sensor output signal. Alternatively, a target temperature can be controlled to minimize the heat flux.

Method for temperature measurements of surfaces with a low, unknown and/or variable emissivity

Devices and corresponding methods can be provided to measure temperature and/or emissivity of a target. Emissivity of the target need not be known or assumed, and any temperature difference between a sensor and the target need not be zeroed or minimized. No particular bandpass filter is required. Devices can include one or two sensors viewing the same target as the target views different respective viewed temperatures. The respective viewed temperatures can be sensor temperatures, and a single sensor can be set to each of the respective viewed temperatures at different times. An analyzer can determine the temperature and/or emissivity of the target based on the respective viewed temperatures and on plural net heat fluxes detected by the sensors and corresponding to the respective viewed temperatures.

A user obtains an individual's body temperature data and transmits the data to a medical monitor (e.g., a medical device) for display. Additional data includes a timestamp and location of the body temperature data. Once the data is transmitted, a user may view the medical monitor for a temperature reading. For example, a doctor may take a patient's temperature and the temperature reading is displayed on a medical monitor. The body temperature data of each patient is detected using a preferred temperature detector, such as a temporal artery thermometer using an arterial heat balance approach. After collecting an individual's body temperature data, the body temperature data can be transferred to a processor. By sending body temperature data for many individuals for a geographic region, the processor can identify a pattern (e.g., a pandemic) in the body temperature data.

The present invention relates to more accurate indication of fever. Temperature data from a large population of individuals are obtained and the temperature data are processed to determine a threshold, at a fever bump, above a normal range of distribution. The fever threshold, along with an individual's temperature, is used to indicate if the individual has a fever. Further, circadian information may be utilized to adjust the temperature data for an individual or the population of individuals.
