Patent number: 11874173Abstract: A temperature detector is provided that is particularly suited towards the differential measurement of foot temperatures in diabetics. A radiation sensor views a surface area of the body and provides a radiation sensor output. Electronics coupled to the radiation sensor and an ambient temperature sensor compute a normalized surface temperature of the area normalized to a specified ambient temperature as a function of a sensed ambient temperature and a sensed radiation.Type: GrantFiled: November 29, 2022Date of Patent: January 16, 2024Assignee: Exergen CorporationInventor: Francesco Pompei

Patent number: 11821794Abstract: 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.Type: GrantFiled: February 16, 2021Date of Patent: November 21, 2023Assignee: EXERGEN CORPORATIONInventors: Jason N.

Patent number: 10704963Abstract: 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.Type: GrantFiled: August 20, 2018Date of Patent: July 7, 2020Assignee: EXERGEN CORPORATIONInventor: Jason N.

Patent number: 10605664Abstract: An inexpensive thermopile temperature detector is particularly adapted to monitoring of electrical equipment, such as a power bus bar, within an enclosed area such as a cabinet. The detector may have a plastic housing, a thermopile sensor and a plastic Fresnel lens. Each sensor also includes a calibrated element such that, but for calibration, the same sensor may be used for various applications for different target sizes and distance or, more generally, with respect to effective target percentage of field of view.Type: GrantFiled: November 8, 2018Date of Patent: March 31, 2020Assignee: EXERGEN CORPORATIONInventor: Francesco Pompei

Patent number: 10520366Abstract: 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.Type: GrantFiled: November 3, 2017Date of Patent: December 31, 2019Assignee: Exergen CorporationInventors: Francesco Pompei, Janette H.

Patent number: 10215643Abstract: There are many industrial applications in which non-contact temperature sensing is useful for increasing production speed and quality, such as printing, laminating, extrusion, and metal forming. Disclosed is a non-contact temperature determining apparatus which uses two wide wavelength bands integrating sensors to determine the radiance ratio of a target and thereby determine a corresponding temperature of the target. Also disclosed is a non-contact temperature determining apparatus in which a beam splitter passes one wide wavelength band to a sensor and reflects another distinct wide wavelength band to another sensor from which temperature can be determined. A disclosed embodiment of the dual waveband temperature detector improves upon traditional and currently available ratio pyrometers by further reducing the cost of the system, making installation and use easier, and improving temperature detection for low temperature industrial applications.Type: GrantFiled: May 5, 2016Date of Patent: February 26, 2019Assignee: Exergen CorporationInventors: Alexander Stein, Francesco Pompei

Patent number: 9927305Abstract: 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.

Patent number: 9194749Abstract: Body temperature measurements are obtained by scanning a thermal radiation sensor across the side of the forehead over the temporal artery. A peak temperature measurement is processed to compute an internal temperature of the body as a function of ambient temperature and the sensed surface temperature. The function includes a weighted difference of surface temperature and ambient temperature, the weighting being varied with target temperature through a minimum in the range of 96° F. and 100° F. The radiation sensor views the target surface through an emissivity compensating cup which is spaced from the skin by a circular lip of low thermal conductivity.Type: GrantFiled: August 16, 2010Date of Patent: November 24, 2015Assignee: Exergen CorporationInventor: Francesco Pompei
