Abstract
In one embodiment, apparatus is provided with a substrate on which a photosensor and a light source are mounted. The photosensor is configured to receive light in an optical band about a wavelength of 940 nanometers; and the light source is configured to transmit light in an optical band about a wavelength of 940 nanometers. Circuitry that is physically supported by the substrate, and that is electrically coupled to the photosensor and the light source, terminates in electrical contacts that are physically supported by the substrate. Other embodiments are also disclosed.
