Two general approaches to flat winding are discussed. in one method, the winding sequence begins by winding the first layer on a spiral pattern inside to out, then winding the next layer outside to in. in another method, two successive layers are wound by metering out a predetermined length… More

The requirement for angle measurement in the presence of translation is not uncommon, yet traditional angle encoders do not accommodate translation, even when the measurement angle is small. the proposed technical approach involves a novel position encoding arrangement in which an absolute position… More

Several factors can disturb the perfection of a winding and limit the length which can wound successfully. these factors include temperature cycling of wound spools, imperfections or variability of fiber diameter, spool contour irregularities, and crossover lines not following a regular pattern… More

The recent development of passive fiber optic sensor systems allows for the first time the ability to develop all-dielectric hydrophone arrays. these fiber optic sensor systems also have the potential for being extremely low in cost so that they may in many instances be considered disposable. the… More

The technology to allow replacement of personnel by mobile robots in high risk situations is available today. the robotics approach suitable for most immediate deployment is to use the robot as an extension of human muscle and sensing, and to use the human brain by means of a high bandwidth fiber… More

The technology to allow replacement of personnel by mobile robots in high risk situations exists today. the near term approach, not requiring extensive development of artificial intelligence requires use of a broad bandwidth secure, anti jam communications link to allow man-in-the-loop operation.… More

Development of a system for high strength fiber optic splicing for application in precision spool winding facilities is proposed. phase i effort would be devoted to literature review, selection of splicing method, definition of splicing procedures, conceptual design, and phase ii plan. procedures to… More

The proposed phase i program will analyze the application of two new communication technologies are (1) paying out an optical fiber from the rpv and probably also simultaneously from a surface ship or submarine so as to form a continuous physical bi-directional communication link between the rpv and… More

Interferometric fiber optic gyro (ifog) optical fiber coil windings are precision level winding between flanges. to make these windings insensitive to thermal gradients across the wound pack, the innermost wound layers is at the center of the measurement path fiber coil. alternate pairs of… More

Missile defense systems for battle management require dense computing for several extremely complex simultaneous information processing requirements. The computation architecture must be highly flexible and rapidly reconfigurable. OPTELECOM, Inc. offers to develop a proprietary optical switch… More

Use of photonic communications technology on military aerospace vehicles offers significant advantages in weight, volume, reduced cost and improved reliability for these vehicles. Weight and volume savings come from replacement of copper wire andelectronic termination hardware in cable assemblies… More
