Abstract: A method and device for aligning and connecting an optical fiber (or device) with another optical device, are disclosed. The method rotates the optical fiber about three axes that intersect at the end surface of the fiber core so that rotation of the fiber does not cause a translation of the end of the fiber. This allows the alignment to be done quickly and accurately. Further, by making one of the axes co-linear with the longitudinal axis of the fiber, variations or defects in the end surface (or a lens mounted thereon) can be accounted for in the alignment procedure. Once aligned the housings of the optical devices are soldered together using a hot air nozzle. The nozzle can then direct cool air toward the housings to rapidly cool the solder, or the temperature of the air can be slowly ramped down to provide for controlled cooling of the solder.

Abstract: An ergonomic pillow comprises a body including an inclined surface on either side, an arcuate central recess, and a slope near either side extended from the inclined surface to the recess so that either slope has the highest elevation on a top surface of the body; a front lengthwise projection member having a front slant extended from a bottom of the body adjacent to the recess; first and second cavities on the bottom of the body adjacent to either side and disposed corresponding to either slope; and an elongate third cavity at an underside of the projection member having the same orientation as the projection member. The pillow appropriately support face, ear, spine and shoulder for relaxing head and spine of a user in face-up or side sleeping.
