  • Sensor and housing in a replicating system to facilitate detection of objects using electromagnetic radiation
    Patent number: 8653440
    Abstract: Exemplary embodiments can be used in a replicating system to guide source electromagnetic waves, such as infrared (IR) radiation, from an emitter of a reflective-type sensor towards an object held on a support mechanism and to guide reflected electromagnetic waves that are related to the source electromagnetic waves to a receiver of the reflective-type sensor. The height of the support mechanism can be adjusted based on whether the object is detected.
    Type: Grant
