These sensors are attached to the ceiling in each office as there are uncertainties with measuring indoor illuminance on the workplane
in long-term monitoring studies, such as furniture's/occupants' shading and monitors'/windows' luminance on sensors (Reinhart 2001).
Low-wattage linear LEDs integrated into the workstation furniture send light upward, which in turn bounces off of the metal and provides the bulk of general lighting on the workplane
For continuous dimming, each luminaire was independently controlled to supplement natural lighting to ensure that only the minimum threshold for horizontal workplane
illuminance was met.
SENSOR LOCATION Sensor Should be Located Over a Workplane

The value comparison of average illuminance on workplane

Additionally, this model includes a very basic method of simulating the user interaction with the blinds, essentially setting a threshold average workplane
illuminance at which the blinds are deployed, and assuming that once deployed the blinds will remain closed until the next day.
Housed in a compact universal head, the spindle can be rotated around an axis 45[degrees] from the workplane
The next step is assigning operations to each workplane
that can be most efficiently performed while the part is in that orientation.
For those users who work in 3D, both versions now display workplane
intersections with existing 3D objects, making work plane visualization simple.
Another factor in the decision was ESPRIT's associative connection to their CAD system that enables the CAM system to read part features such as holes, pockets, slots, etc, as well as their attributes, including height, depth, and workplane
The indirect component provides a foundation of uniform, glare-free ambient illumination throughout the space, while the direct component delivers light directly to the workplane
via a deep-cell parabolic louver system.
