    摘要: A fiber optic gyroscope (FOG) including a depolarizer having substantially equal first and second fiber segments of polarization maintaining (PM) fiber coupled to a single mode (SM) fiber loop. The first PM fiber segment includes sections of fiber connected together via a splice having an angle from about 35° to 55° between major axes of polarization of the sections which it connects. Similarly, the second PM fiber segment includes sections of fiber connected together via a splice having an angle from about 35° to 55° between major axes of polarization of the sections which it connects. The length of each fiber section is chosen to maintain the thermal and mechanical symmetry of the SM fiber loop.

    摘要: An electronic component lead or tab crimping apparatus adapted for use with a conveyor system in the assembly of printed circuit (PC) boards includes an upper assembly having an upper interchangeable plate and a lower actuator plate and further includes a pneumatically actuated lower assembly. The interchangeable plate includes a plurality of spaced apertures within each of which is disposed a lead/tab engaging, crimping element. The upper assembly is initially displaced upward by the pneumatically actuated lower assembly to a position in close proximity to and in alignment with the lower surface of a PC board such that each of the crimping elements is disposed in close proximity to a lead, or leads (or tabs), of an electronic component positioned on the PC board. The lower assembly then displaces the actuator plate upward by cam action such that the actuator plate simultaneously engages and pivotally displaces the crimping elements resulting in crimping of the electronic component leads or tabs. The actuator plate of the upper assembly is then lowered by the lower assembly allowing for disengagement of the leads/tabs by the crimping elements, followed by further lowering of the upper assembly by the lower assembly to permit the PC board with crimped leads/tabs to be displaced by the conveyor system and another PC board to be moved in position for lead/tab crimping.

    摘要: An octupole winding pattern for winding a fiber optic coil includes at least two layers of an eight-layer winding pattern having an end fiber optic coil diameter formed in an opposite direction as a substantial portion of a remaining portion of the respective layer. The selectively arranged octupole winding pattern may be used in a fiber optic gyroscope. A spool onto which the fiber optic coil is wound may be removable. Preferably, the octupole winding pattern is advantageously arranged to provide a substantial amount of optical symmetry with respect to a winding centerline of the fiber optic coil. In addition, the octupole winding pattern provides a substantial amount of geometric, mechanical, and thermal symmetry.
