Abstract: Various embodiments of an eyeglass and eyeglass system are provided that can maintain the geometric and optical quality of a lens supported by the eyeglass. The eyeglass can comprise a frame, a support member carried by the frame, and a lens mounting area or groove extending at least partially along at least one of the frame and the support member. The support member can be pivoted, moved, or deflected relative to the frame between a retaining position and an open position. In the open position, the lens can be seated within the lens mounting area. In the retaining position, the support member and the frame retain the lens without exerting deformative forces on the lens. Accordingly, the as-molded geometric and optical qualities of the lens can be preserved.

Abstract: Eyewear, such as a goggle, is provided that can include an anterior module (such as a lens support) and an interchangeable posterior module (such as a faceplate). The anterior module can be adapted to support at least one lens in a wearer's field of view. The posterior module can be adapted to fit against a contour of the wearer's face and can be selectively interchangeable with the anterior module to modify at least one physical characteristic of the eyewear. In some embodiments, the anterior and posterior modules can be coupled by a suspension assembly in order to allow articulation of the posterior module relative to the anterior module for evenly distributing forces against the wearer's face. Further, the anterior module can be rigid for maintaining the lens in an optically-desirable orientation. Furthermore, the goggle can comprise an interchangeable lens mechanism to facilitate interchanging of lenses in the goggle.

Abstract: An earstem for eyeglasses is provided that can incorporate an interchangeable elastomeric traction member disposed in a recessed seat which extends along a length of the earstem to provide a contact area between the earstem and the head. The traction member can be disposed along the bottom portion of the earstem and/or around the periphery of the earstem. The traction device can be detachably coupled to the earstem so that the traction device can be exchanged to accommodate different needs or situations.

Abstract: An eyeglass component mounting system is provided that can comprise a frame and at least a first ear stem. The first ear stem extends rearwardly from the frame and defines an anterior end and a posterior end. The anterior end of the first ear stem can be hingedly coupled to the frame such that the first ear stem can be pivotably movable between a stowed position and a deployed position. The first ear stem can comprise a mounting area configured to receive an eyewear component thereon such that the eyewear component can be removed or seated onto the mounting area when the first ear stem is in the stowed position and such that the eyewear component is retained on the mounting area when the first ear stem is in the deployed position.

Abstract: An audio cassette adapter with cable and connector storage in the body of the cassette. Internal cable storage is facilitated by an internal retractable mechanism that reduces the amount of storage external to the audio cassette adapter housing. In one embodiment, the internal retractable mechanism includes a cable support around which the cable is wound and a separate support driver engaged with the cable support that drives the cable support.

Abstract: Methods for improving purification and quantification of platelet derived growth factor (PDGF) proteins having structural heterogeneity are provided. Preparation of substantially pure isoforms of these proteins is achieved using TSK sulfopropyl cation exchange chromatography and reverse phase high performance liquid chromatography. A reverse charged capillary zone electrophoresis method enables quantification of substantially pure isoforms of these proteins resulting from endoproteolytic post-translational modifications. Compositions of the invention are substantially purified isoforms of secreted PDGF proteins having structural heterogeneity, more particularly purified intact, single-clipped, and double-clipped isoforms of recombinant PDGF-BB. Pharmaceutical compositions comprising at least one of these substantially purified recombinant PDGF isoforms and methods for their use in promoting wound healing are also provided.

Abstract: An optical drop structure comprising a multi-port optical circulator (MOC), a first reflection filter unit optically connected in series between a first port and a second port of the MOC, a second reflection filter unit optically connected in series between a third port and a fourth port of the MOC, and the optical drop structure is arranged, in use, in a manner such that, a first optical signal entering through a fifth port of the MOC is subjected to the first reflection filter unit and exits at a sixth port of the MOC and a reflected portion of the first optical signal exits at a seventh port of the MOC, and a second optical signal entering through the sixth port of the MOC is subjected to the second reflection filter unit and exits at the fifth port of the MOC and a reflected portion of the second optical signal exits at an eights port of the MOC.

Abstract: A retention mechanism has a base and a snap ring that are mounted to two components. The snap ring has a hole for attaching a first component. A conical element with a rounded knob protrudes from the snap ring. The base is cylindrical and has a cap with a rounded face and a conical opening that tapers to a cylindrical hole. Both the knob and the base are slit for greater compliance. After the base and snap ring are mounted to their respective components, the snap ring may be removably connected to the base by inserting its knob into the conical opening in the base. The complementary shapes of the snap ring and base allow for significant axial and angular misalignment. The slits allow the snap ring and base to elastically deform. The snap ring and base are disengaged by pulling the snap ring away from the base.

Abstract: A two-piece retention mechanism has a base and a snap ring that are individually mounted to two separate components that a user desires to releasably join. The snap ring has a round body with a hole for attaching the first component thereto. A conical element with a spherical tip protrudes from the snap ring body. The base has a cylindrical body for mounting to the second component. The body of the base has a cap with a rounded face and a conical opening that tapers down to a cylindrical hole. After the base and snap ring are mounted to their respective components, the snap ring may be removably connected to the base by inserting its spherical tip into the conical opening in the base. The complementary shapes of the snap ring and base allow for significant axial and angular misalignment. The snap ring and base elastically deform and emit an audible “snap” during this sequence.
