Abstract: An integrated sensing system for characterizing blood flow in a subject includes a light source assembly including a light source configured to emit light of a particular wavelength. The integrated sensing system includes an integrated circuit electrically connected to the light source assembly. The integrated circuit includes a light detector assembly including multiple light detectors configured to detect light of the particular wavelength; and a correlator configured to determining a delay between optical signals detected by respective light detectors of the light detector assembly.

Abstract: An integrated optical biosensor module includes one or more light sources operable to produce light for emission from the module, and an integrated circuit chip including a photosensitive region. The photosensitive region includes one or more photodetectors operable to detect light produced by the one or more light sources and reflected by a subject that is outside the module. The integrated circuit chip is operable to determine a physiological condition of the subject based on signals from the one or more photodetectors. A clear mold covering encapsulates the one or more light sources, wherein the clear mold covering includes one or beam shaping elements each of which is disposed so as to intersect a path of a light beam from an associated one of the one or more light source.
