Abstract
Example sensor systems to detect a presence of a person at a loading dock are disclosed. An example sensor system includes a housing mountable to a support structure. An emitter is supported by the housing and is to emit a projection. An actuator is coupled to at least one of the housing or the emitter, where the actuator is movable between a first position and a second position relative to the support structure. The emitter is to emit the projection along a first path when the actuator is in the first position and the emitter is to emit the projection along a second path when the actuator is in the second position. A receiver is supported by the housing at a substantially fixed location relative to the emitter proximate the emitter. The receiver is to receive a reflection of the projection reflected off of the person positioned within a line of sight of the projection.
