International Classification:

G02B006/26
G02B006/42

US Classification:

385 18, 385 47

Abstract:

A fiber-attached optical device with in-plane micromachined mirrors includes a cover having at least one reflector formed on one side and a substrate having a plurality of micromachined optical mirrors formed substantially on a single plane on a side facing toward the mirrored side of the cover. The micromachined optical mirrors are controllable to reflect optical signals between a plurality of optical fiber segments via the at least one reflector. The plurality of optical fiber segments can be attached to either the cover or the substrate so as to form an integrated package including the substrate, the cover, and the plurality of optical fiber segments. The mirrors can be controlled to variably attenuate the optical signals.

Appl. No.:

13/241136

Inventors:

Jeffrey Ralph Swift - Andover MA, US

Assignee:

OBP CORPORATION - Lawrence MA

International Classification:

A61B 1/32

US Classification:

600220, 600219

Abstract:

A speculum includes upper and lower members and a linear support member. The upper member includes an upper blade. The lower member includes a lower blade and a handle portion. The lower blade includes a support structure at a proximal end thereof which extends vertically on the right or left side of the lower blade, and a handle portion extending downwardly from the lower blade and defining a vertical track. The linear support member has a proximal end pivotally connected to the upper blade, a distal end, and an elongated body between the proximal and distal ends. The elongated body slidably engages the vertical track of the handle portion. The linear support member is formed with a hidden slot which slidably receives the support structure of the lower blade.
