    Abstract: In one embodiment of the invention, a non-invasive method of measuring blood pressure is disclosed. The method includes scanning for ECG data with a portable cuffless blood pressure measuring device including, forming an electronic circuit with a first electrode and a second electrode of the portable cuffless blood pressure measuring device by contacting the first electrode with a user's temple and contacting the second electrode with the user's finger holding the portable cuffless blood pressure measuring device; concurrently scanning for PPG data with the cuffless blood pressure measuring device during ECG scanning by placing the PPG sensor to the user's temple; cross-correlating the ECG data and the PPG data to determine a PWTT for the user; receiving one or more physiological data of the user; and using regression analysis to predict systolic blood pressure of the user in response to the PWTT and the one or more physiological data.

    Abstract: In one embodiment, a method is disclosed that includes selecting a first color sample within a target area in a first image of a first object displayed by a display device; selecting a second color sample within a target area in a second image of a second object displayed in the display device; comparing the first color sample against the second color sample to determine a measure of color difference or a measure of color equivalence between the first color sample of the first object and the second color sample of the second object; and displaying the results of the comparison to a user in the display device. One or more of these functions may be performed with a processor.
