ABSTRACT:
Headlamp alignment is detected using a collection of intelligent, independent sensor units, each of which incorporates a vertical array of sensing elements capable of detecting headlamp illumination. The sensor units are networked together and can be coupled to a host controller. The host controller can provide a user interface via a touch screen and a Web server, and can further communicate with a plant network for interfacing with manufacturing databases. The network of sensor units can accommodate four or more sensors, which allows multiple vehicles and multiple headlamp types to be audited without physical movement of the sensor units. The sensor units are low in power consumption and can receive power over the same cable providing network communication. Incorporation of non-volatile memory within the sensor units allows factory data to be recorded within each sensor unit and permits convenient replacement of units in the field.
