Appl. No.:

13/862792

Inventors:

Robert T. Hewlett - Cumming GA, US
Steven M. Frank - Suwanee GA, US

International Classification:

G02B 27/14

US Classification:

359629

Abstract:

According to certain embodiments, a system includes beamsplitter sets, where each beamsplitter set comprises a first beamsplitter module and a second beamsplitter module aligned with the first beamsplitter module. The first beamsplitter module receives a first beam traveling along a first optical path. The first beamsplitter module splits the first beam into a first output beam transmitted along the first optical path and a first split beam transmitted to the second beamsplitter module along a reflected beam path. The second beamsplitter module receives the first split beam. The second beamsplitter module splits the first split beam into a second output beam transmitted substantially parallel to the reflected beam path and a second split beam transmitted substantially perpendicular to the reflected beam path.

Abstract:

A frame, one or more wheels rotationally attached to the frame, two or more end feet attached to opposite ends of the frame, one or more end safety tether attachments, and a flip-pole attachment. The frame straddles the roof peak so the end feet are stably positioned on opposite roof surfaces. The wheels enable the device, when flipped to its inverted position, to be rolled up and down the roof for installation and removal. The flip-pole attachment enables attachment of a flip pole for use in installing and removing the device from a ladder. And the end tether attachments enable workers to couple their safety tethers to the secured device so that if they fall their fall will be arrested for safety. In typical embodiments, an outrigger assembly is included with peak-mounting side feet for nesting on the roof peak and with side tether attachments for side attachment.
