Abstract: Techniques are described for non-invasive, dual-altitude-based measurement of blood pressure of a user using a portable electronic device having a sensor head. Illumination is projected into a body part and received by photodetectors. A changing amount of illumination received by the photodetectors changes corresponds to a changing amount of blood volume in elastic circulatory system pathways in the body part. Measurements of the received illumination are obtained at multiple altitudes relative to the user's heart. A linear fit is applied to the multiple measurements based on at least a predetermined slope-calibration factor to obtain a slope-corrected mean blood pressure measurement (BPM). Some embodiments use similar techniques to further measure pulse-to-mean (PTM) at multiple altitudes. The PTM measurements are used to simulate a systolic and/or diastolic BPM.

Abstract: Techniques are described for passive three-dimensional image sensing based on referential image blurring. For example, a filter mask is integrated with a lens assembly to provide one or more normal imaging bandpass (NIB) regions and one or more reference imaging bandpass (RIB) regions, the regions being optically distinguishable and corresponding to different focal lengths and/or different focal paths. As light rays from a scene object pass through the different regions of the filter mask, a sensor can detect first and second images responsive to those light rays focused through the NIB region and the RIB region, respectively (according to their respective focal lengths and/or respective focal paths). An amount of blurring between the images can be measured and correlated to an object distance for the scene object. Some embodiments project additional reference illumination to enhance blurring detection in the form of reference illumination flooding and/or spotted illumination.

Abstract: Techniques are described for passive three-dimensional (3D) object authentication based on image sizing, such as for biometric facial recognition. For example, during a registration routine, an imaging system captures images of a registering user's face at multiple distances. The images can be processed to extract registration dimensions, including individual deterministic structural dimensions, dimensional relationships that are static over changes in imaging distance, and dimensional relationships that changes predictably over changes in imaging distance. During an authentication routine, the imaging system again captures authentication images of an authenticating user's face (purportedly the previously registered user) at some authentication imaging distance and processes the images to extract authentication dimensions.
