International Classification:

B29D 1100

US Classification:

264 136, 264 138

Abstract:

A method and mold assembly to control the polymerization of a molded article. In one embodiment, an amorphous posterior mold comprising a non-critical surface having a controlled radius of curvature is used to produce molded articles. In an alternate embodiment, ophthalmic lenses are produced using a posterior mold in which the concave surface of the non-critical surface is filled with a liquid having a similar refractive index as the mold material. In still another embodiment, a positive lens is placed at a predetermined distance adjacent to the mold assembly to alter the irradiation path to the mold assembly. In still another embodiment, a positive lens is placed within the concave surface of the posterior lens.

International Classification:

G10L 708
G06F 1542
A61B 500

US Classification:

3645135

Abstract:

An interactive patient assistance device houses both preselected doses of medication and a physical testing device. Both medication and the testing device are normally retained within separate compartments within the device away from access by the patient. The device keeps track of medication and diagnostic testing schedules. The device is also capable of receiving and interpreting verbal commands of the patient. The device makes a preselected dose of medication available to the patient in response to either the medication schedule or the receipt of a verbal command by the patient. Likewise, the testing device is made available to the patient in response either to the testing schedule or the receipt of a verbal command from the patient.

Assignee:

Bausch & Lomb Incorporated - Rochester NY

International Classification:

B29D 1100

US Classification:

264 26

Abstract:

An apparatus and method for hydrating is provided for hydrating a lens and extracting residual materials from the lens. The apparatus includes a shaft; multiple arms extending radially from a lower end of the shaft about a central axis in a star-shaped pattern, each arm including a fin extending therebelow such that multiple fins also extend radially with respect to said central axis, wherein the fins including lower outer edges that converge and form a nozzle face. A fluid transport passage extends through the shaft and terminates at an opening in the nozzle face, whereby fluid can be evacuated from the lens through this passage. Preferably, at least one recessed channel is formed in the nozzle face where the fins converge, wherein each of these channels extends from the opening in the nozzle face that forms a terminus of the fluid transport passage to a space between two adjacent fins. The lower outer edges of the fins have an arcuate surface, the arcuate surfaces forming a convex-shaped nozzle face. Preferably, the outer tips of the arms extend radially from the central axis of the apparatus further than the fins extend.

International Classification:

G10L 708
A61B 500

US Classification:

222638

Abstract:

An interactive patient assistance device houses first and second compartments for storing a first item and a second item away from access by the patient. First and second delivery mechanisms are associated with the first and second compartments for making the first stored item available to the patient in response to a first command signal and for making the second stored item available to the patient in response to a second command signal. The first and second items are delivered to the patient according to schedules stored in resident memory. The schedules may be altered by a prescribed command issued by the patient.
