Hand-held medical-data capture-device having optical detection of vital signs from multiple filters and interoperation with electronic medical record systems via an authenticated communication channel

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 filtered 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 filtered 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, generating temporal-variation identified 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 identified temporal bandpass filtered spatial clustered spatial bandpass filtered identified pixel values of skin;
• and
• a 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 a connection is established by the wireless communication subsystem to an external device and the representation of the at least one vital sign is pushed from the apparatus through the wireless communication subsystem, thereafter the external device controls flow of the data between the apparatus and the external device, wherein the connection further comprises an authenticated communication channel.
