Abstract: A fiber optic projection device is provided that includes red, green and blue fiber optic sources, each of which includes at least one fiber amplifier for emitting an amplified signal of a predetermined wavelength. To provide signals that are scalable to high power levels, each fiber optic source can include a master oscillator, a plurality of fiber amplifiers for amplifying the input signals provided by the master oscillator and a combiner for combining the amplified signals emitted by each of the fiber amplifiers. While the fiber amplifier of each fiber optic source can be a dual core fiber that is appropriately doped, the red fiber optic source can include fiber amplifiers that rely upon Raman gain to provide the desired amplification. The red fiber optic source therefore not only includes a master oscillator, but also includes a red subharmonic oscillator for generating signals having a Raman seed wavelength for amplification by the fiber amplifiers.

Abstract: A fastener for fastening and joining sections of composite material together is disclosed comprising a substantially cylindrical core component and substantially cylindrical hollow sleeve component, one or both of which are pre-coated with a curable organic coating, and methods of fastening aircraft components together using such fasteners.

Abstract: The data processing system includes a property inspection data entry device for collecting and storing inspection data during the inspection of a property. The property inspection data entry device typically includes a scanner which is responsive to labels which are associated with the property as well as various items located about the property which include indicia representative of predetermined characteristics of the rental unit. The property inspection data entry device also includes a data entry device, such as a keypad, for providing manual entry of additional inspection data. The data processing system can also include a maintenance data entry device for collecting and storing maintenance data relating to maintenance activities performed on a property. The data processing system also includes a host computer for electrically communicating with the property inspection data entry device and the maintenance data entry device prior to and subsequent to inspection and maintenance activities, respectively.
