Claim 15:
16. A method comprising:
generating, by a light source driver, a driving signal;
producing, by a demultiplexer and using the driving signal, a plurality of output driving signals;
delivering each of the plurality of output driving signals to a respective one of a plurality of sensors;
receiving, by an amplifier, from a first sensor of the plurality of sensors, a first signal associated with an event representative of a positioning of a substrate within a device manufacturing machine;
generating, by the amplifier and based on the received first signal, a second signal;
receiving, by an analog-to-digital converter, the second signal;
generating, by the analog-to-digital converter and based on the second signal, a third signal; and
obtaining, by a processing device and based on the third signal, information about the positioning of the substrate within the device manufacturing machine.
