Filed:

Nov 11, 2002

Appl. No.:

10/293689

Inventors:

Zach L. Rogers - Layfayette CO
Michael J. Holtz - Boulder CO
Caroline M. Clevenger - Boulder CO
Neall E Digert - Westminster CO

Assignee:

Architectural Energy Corporation - Boulder CO

International Classification:

G02B 1700

US Classification:

359596, 359597, 160104

Abstract:

Each light slat of the Mini-Optical Light Shelf daylighting system consists of a light reflecting segment that comprises the top surface of the light slat. A light shading segment and a light redirecting segment comprise the bottom surface of the light slat. The daylight incident on the daylight collection section of the glazing is collected by the optically shaped light reflecting segment of the light slats and redirected onto the ceiling plane of the room in a glare free, uniform manner. In addition, the light redirecting segment of each light slat functions to redirect incident daylight, that is reflected off the light reflecting segment of the adjacent light slat at angles above a predetermined threshold, onto the ceiling plane of the room. The light shading segment functions to block low altitude components of incident daylight from entering the room.

Abstract:

The diagnostic system makes use of a knowledge based controller and a plurality of data logger units, at least one of which is a wireless unit, to collect temporally coordinated data indicative of the real time operation of a system under test that comprises a plurality of spatially disjunct but operationally interdependent components. The diagnostic system controller automatically architects an instrumentation plan to collect the data and calculates performance factors from this collected data. A comparison of the calculated performance factors with optimum and typical failure mode performance factors identifies performance problems in the system under test.
