    Abstract: An electronic device may include an optical sensor configured to emit a reference light to a reference object and detect the reference light reflected from the reference object during calibration, and emit a measurement light to a target object and detect the measurement light reflected from the target object during a measurement; and a processor configured to perform the calibration of the optical sensor while the electronic device is disposed to oppose or in contact with the reference object by controlling the optical sensor to emit and detect the reference light, and estimate bio-information based on a light quantity of the measurement light that is reflected from the target object by the optical sensor, and a light quantity of the reference light reflected from the reference object.

    Abstract: An assay result reading device for reading the result of an assay performed using a liquid transport carrier may include at least one light source capable of emitting light incident upon at least one of two or more spatially separated zones of the carrier, a photodetector so positioned as to be capable of detecting light emanating from each of the two said zones and generating signals representing the presence or absence of a fluid sample in the respective zone, and a computation circuit. The computation circuit may be responsive to the signals to calculate a flow rate for a fluid flowing along the carrier, compare the calculated flow rate to upper and lower limits, and reject the assay result if the calculated flow rate is outside the upper and lower limits.
