Abstract

One aspect provides a system including a sensor adjustment component comprising: a memory device having adjustment information stored therein; signal source capable of producing a signal detectable by a sensor to be adjusted; and one or more processors; wherein the one or more processors are configured to execute program instructions to operate the signal source to produce a predetermined signal pattern detectable by a measurement component of the sensor to be adjusted; and wherein the predetermined signal pattern comprises the adjustment information. Other aspects are disclosed.

Claims

a sensor adjustment component comprising;

a memory device having adjustment information stored therein;

signal source capable of producing a signal detectable by a sensor to be adjusted; and

one or more processors;

wherein the one or more processors are configured to execute program instructions to operate the signal source to produce a predetermined signal pattern detectable by a measurement component of the sensor to be adjusted; and

wherein the predetermined signal pattern comprises the adjustment information.

2. The system of claim 1, wherein:

the sensor to be adjusted is an optical sensor;

the signal source is a light engine;

the predetermined signal pattern is a light pattern; and
