Abstract:
A transducer includes a base, a horn, and a central element. The horn includes a first end coupled to the base and a second end extending from the base and having a perimeter that defines a substantially planar face of the transducer, the horn defining a horn length along a horn surface between the first end and the second end of the horn. The central element includes a first end coupled to the base and a second end extending from the base along a longitudinal axis of the horn, the central element defining a central element length along a central element surface between the first end and the second end of the central element, the central element length being substantially equal to the horn length.
Abstract:
A temple bar assembly for eyeglasses is provided having several adjustable members wherein all of the joints are formed by utilizing in-mold-assembly techniques to reduce the assembly steps required to form such a temple bar assembly. The temple bar assembly includes at least one of the following adjustment points: temple length, inclination angle and/or hinge attachment all formed using IMA while further resulting in a temple bar that has increased adjustability and utility. Also, the materials selected may include either hard or soft plastics to form either component.
Abstract:
A novel nose pad assembly for eyeglasses is provided wherein the support and nose pad are formed as a fully articulating ball and socket joint. The ball and socket joint provides excellent adjustability of the nose pads in a simple mechanical construction. In a unique method of forming the nose pad assembly the support structure (ball) is formed in a first molding step and an adjustable pad member is molded directly over the ball of the support structure in a second molding step. The present invention utilized in-mold-assembly techniques to reduce the assembly steps required to form such a nose pad assembly while further resulting in a nose pad that has increased adjustability and utility. Alternately, the pad portion may be formed first and the support structure formed second. Also, the materials selected may include either hard or soft plastics to form either component.
Abstract:
The disposable safety eyewear has a lens portion having a bridge portion and a nose support thereon. Left and right temple bars are connected to the lens portion by living hinges. The living hinges are operable between an open position and a folded position. Mating formations secure the living hinges in its respective folded position.
Abstract:
A novel hinge assembly for eyeglasses is provided wherein a first structural member for the hinge structure is formed in a first molding step and a second structural member of the hinge structure is formed directly over a portion of the first structural member in a second molding step. The present invention utilizes in-mold-assembly techniques to reduce the assembly steps required to form such a hinge assembly while further resulting in a hinge assembly that has increased adjustability and utility. Specifically, the overmolded components form a ball and socket type joint allowing a large degree of lateral rotation in one direction and a limited amount of freedom in a second direction. This hinge allows the temple portion of the eyeglasses to be folded against the brow bar and the inclination angle between the temples and the brow bar to be adjusted.

Abstract:
A novel frame construction for eyeglasses is provided wherein the upper frame member is formed to have greatly enhanced flexibility to increase the overall adjustability, comfort and fit of the eyeglasses. The upper frame member includes areas wherein the material is selectively weakened to create predetermined flex points periodically within the frame member. Additionally, the weakened areas may be filled and/or covered with a second material that is more flexible than the base material used to form the frame member. The enhanced flexibility allows the upper frame member to flex as the temple members of the eyeglasses are stretched outwardly providing a comfortable fit for a wide range of wearers. Further, the top edge of the eyeglass lens may include formations that provide clearance for the deflection of the top frame member.
Abstract:
A reservoir assembly for use in an ophthalmic fluid delivery device adapted to deliver an ophthalmic fluid in the form of a mist to an ocular region of a patient is provided, wherein the device has a lumen-defining component configured to deliver the fluid from the reservoir assembly. The reservoir assembly includes a reservoir defining an aperture and a cavity in fluid flow communication with the aperture, a fluid contained in the cavity of the reservoir, and a gasket traversing the aperture. The gasket defines a passage configured to receive a portion of the lumen-defining component and to permit the flow of the fluid from the cavity and through the aperture when the portion of the lumen-defining component is inserted through the passage. The gasket is also configured to substantially prevent the flow of the fluid from the cavity and through the aperture when the portion of the lumen-defining component is not inserted through the passage.
