Abstract

In one implementation, an apparatus estimates body core temperature from an infrared measurement of an external source point using a cubic relationship between the body core temperature and the measurement of an external source point is described, estimates temperature from a digital infrared sensor and determines vital signs from a solid-state image transducer, or determines vital signs from a solid-state image transducer and estimates body core temperature from an infrared measurement of an external source point using a cubic relationship between the body core temperature and the measurement of an external source point; after which the estimated and/or determined information is transmitted to an external database.

First claim

The invention claimed is:

1. A non-touch thermometer to measure a temperature, the non-touch thermometer comprising:
a microprocessor;
a wireless communication subsystem that is operably coupled to the microprocessor and that is operable to transmit a representation of the temperature;
a battery operably coupled to the microprocessor;
a single button operably coupled to the microprocessor; and
a digital infrared sensor operably coupled to the microprocessor with no analog-to-digital converter operably coupled between the digital infrared sensor and the microprocessor, the digital infrared sensor having only digital readout ports, the digital infrared sensor comprising a low noise amplifier, an analog-to-digital converter, a digital signal processor, and a pulse width modulator (PWM) in a single industry standard package; wherein the digital infrared sensor is configured with no need for recalibration after an initial factory calibration with an emissivity range from 0.1 to 1.0,
wherein the microprocessor is operable to receive from the digital readout ports a digital signal that is representative of an infrared signal detected by the digital infrared sensor and the microprocessor is operable to determine the temperature from the received digital signal by using the PWM.

2. The non-touch thermometer of claim 1 , wherein a display device further comprises:
a green traffic light operable to indicate that the temperature is good;
an amber traffic light operable to indicate that the temperature is low; and
a red traffic light operable to indicate that the temperature is high.

3. The non-touch thermometer of claim 1 , the microprocessor further comprising:
a camera operably coupled to the microprocessor and providing at least two images to the microprocessor; and
the microprocessor including a cropper that is operable to receive the at least two images and operable to crop the images to exclude a border area of the images, generating at least two cropped images,
the microprocessor also including a temporal-variation-amplifier of at least two cropped images that is operable to generate a temporal variation, the microprocessor also including a vital-sign generator that is operably coupled to the temporal-variation-amplifier that is operable to generate at least one vital sign from the temporal variation and the microprocessor also operably coupled to a display device that is operable to display the at least one vital sign.

4. The non-touch thermometer of claim 3 , wherein the temporal-variation-amplifier further comprises:
skin-pixel-identifier.

5. The non-touch thermometer of claim 3 , wherein the temporal-variation-amplifier further comprises:
a regional facial clusterial module.

6. The non-touch thermometer of claim 3 , wherein the temporal-variation-amplifier further comprises:
a first frequency filter.

7. The non-touch thermometer of claim 1 further comprising:
the digital infrared sensor having no analog sensor readout ports.

8. The non-touch thermometer of claim 1 wherein the wireless communication subsystem transmits to a static Internet Protocol address in order to reduce Internet Protocol discovery burden on the non-touch thermometer.

9. The non-touch thermometer of claim 1 wherein the non-touch thermometer does not support specific discovery protocols or domain name service.

10. The non-touch thermometer of claim 1 wherein a connection is established and data is pushed from the non-touch thermometer through the wireless communication subsystem, thereafter an external device controls flow of the data between the non-touch thermometer and the external device, wherein the connection further comprises: an authenticated communication channel.

11. The non-touch thermometer of claim 1 , the wireless communication subsystem is configured to operate on a specific segment of a network.

12. The non-touch thermometer of claim 1 , wherein the wireless communication subsystem transmits through an Internet Protocol tunnel.

13. The non-touch thermometer of claim 1 wherein the temperature further comprises a body core temperature and wherein determining the body core temperature is based on a cubic relationship representing three thermal ranges between a numerical representation of electromagnetic energy of an external source point and the body core temperature, wherein the cubic relationship includes a coefficient representative of different relationships between the external source point and the body core temperature in the three thermal ranges.
