Claim 16:
17. The method of claim 14, wherein the light pulse is a first light pulse, the pulse period is a first pulse period, the background light level is a first background light level, the threshold signal level is a first threshold signal level, and the reflected light pulse is a first reflected light pulse, further comprising:
emitting, by the light emitter a second light pulse during a second pulse period, wherein the second pulse period includes a timeframe preceding the second light pulse and a timeframe following the second light pulse;
determining a second background light level based on an output of the light detector during the timeframe preceding the second light pulse; and
setting, based on the second background light level, a second threshold signal level for detecting a second reflected light pulse during the timeframe following the second light pulse.
