Hand-held medical-data capture-device having optical detection of vital signs from multiple filters and interoperation with electronic medical record systems through a static IP address without specific discovery protocols or domain name

摘要

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.

1. An apparatus of variation amplification to communicate biological vital signs, the apparatus comprising:
a microprocessor that is programmed to execute:
a cropper that is operable to receive at least two images and that is operable to crop each of the images to exclude a border area of the images, generating at least two cropped images;a skin-pixel-identifier that is operably coupled to the cropper and that identifies pixel values that are representative of skin in the at least two cropped images, generating identified skin pixels;a spatial bandpass filter that is operably coupled to the skin-pixel-identifier and that processes the identified skin pixels, generating spatial bandpassed filtered identified pixel values of skin;a regional facial clusterial module that is operably coupled to the spatial bandpass filter and that applies spatial clustering to the spatial bandpassed filtered identified pixel values of skin, generating spatial clustered spatial bandpassed identified pixel values of skin;a temporal bandpass filter that is operably coupled to the regional facial clusterial module and that is applied to the spatial clustered spatial bandpassed identified pixel values of skin, generating temporal bandpass filtered spatial clustered spatial bandpass filtered identified pixel values of skin;a temporal-variation identifier that is operably coupled to the temporal bandpass filter and that identifies a temporal variation of the temporal bandpass filtered spatial clustered spatial bandpass filtered identified pixel values of skin;a vital-sign generator that is operably coupled to the temporal-variation identifier that generates at least one vital sign from the temporal variation; anda display device that is operably coupled to the vital-sign generator that is operable to display the at least one vital sign; and a wireless communication subsystem that is operably coupled to the microprocessor and that is operable to transmit a representation of the at least one vital sign, wherein the apparatus does not support specific discovery protocols or domain name service.
