Abstract: An apparatus for use in rotational measurement. A rotational assembly is provided that is rotationally movable about a rotational axis. At least two interferometers are provided that are each able to receive a respective light beam, separate it into both reference and measuring beams and direct their respective measuring beam to and receive it back from the rotational assembly. The said rotational assembly includes a plurality of cube corners mounted so that at least one is able to receive from and reflect back to one of the interferometers its measuring beam as the rotational assembly rotates. The interferometers combine their reference and measuring beams into respective detection beams, wherein at least one such detection beam includes an interference signal that is process able to determine any rotational measurement of the rotational assembly and any work piece target attached to it.

Abstract: A metering module (12), or a flow meter (10) employing such, for monitoring fluid flow with a laser light source, a light detector and a processor (14), wherein the fluid (18) may be a gas or liquid. A valve section (22) and a grating section (24) including a fiber Bragg grating (FBG)(28) are provided. The valve section applies strain on the FBG that is representative of the flow of the fluid. An optical fiber (26) couples a probing laser signal (30) to the FBG and the FBG reflects a portion back as a return laser signal (32) that the optical fiber couples to the light detector for detection and processing.

Abstract: A hazard mitigation system (10) to detect intrusion by an object (16) into a track zone (12) at a train station platform. A structure is provided that includes a fixed foundation (34) and a surface layer (30) that is cushionably placed above the foundation, such that the structure is located in the track zone. At least one sensor (22) is mounted between the surface layer and the foundation. This sensor senses the weight of the object upon the surface layer and provides a sensor signal representative of that weight. A control unit (402) receives the sensor signal, processes it to determine whether the object represents a potential hazard, and, if so generates a warning signal. The sensor can particularly include a strain gage (22a) or pressure gage (22b), or a fiber optic sensor (22c). When a fiber optic sensor is employed, it can particularly include a fiber Bragg grating (100).

Abstract: Systems, methods, and products created by the methods that create a photo-magnetic image (102) of an object (112) in photo-magnetic stock (132). A source provides a data signal (118) that is representative of a digital image. The source may particularly include a lens (114) and digital sensor (116) in the manner of a digital camera, or may particularly include an interface (306) to receive the data signal from an external system where it has been captured, stored, or generated. A first coding unit (128, 502) then optically writes the data signal into the photo-magnetic stock and a second coding unit (130) magnetically writes the data signal into the photo-magnetic stock.
