Abstract: An binocular lens system for improving the vision of a patient including first and second ophthalmic lenses. Each of these lenses is adapted for implantation in an eye or to be disposed on or in the cornea. The first lens is biased for distance vision and the second ophthalmic lens is biased for near vision. The ophthalmic lenses may be intraocular lenses which are implanted in the eyes of a patient following removal of the natural lens.
Abstract: An apparatus and system for removing debris and contaminants from water passing through a storm drain generally includes a debris trap adapted to fit within a storm drain a porous, filtering element adapted to separate debris from a water flow passing through the storm drain and a frame for directing the water flow into the porous element. The debris trap includes a frame element adapted to substantially prevent bypass of the debris trap, especially during low water flow conditions. The system may further include a debris block adapted to prevent debris from entering a back curb inlet opening of the storm drain. The debris block includes foam end members for adjustably securing and/or sealing the debris block to edges of the drain inlet.
Abstract: Toric contact or intraocular lenses having a correcting portion characterized by one or more novel constructions that each produce an optical path that improves angular misalignment tolerance. The lens may be constructed with a “smooth atoric” aspect where the optical path through the correcting portion of the lens corrects for both astigmatism and an axisymmetric aberration other than astigmatism, there being no sudden surface discontinuity between the regions that provide the different corrections (thus, “smooth”). In another embodiment, the lens may be constructed with so-called “sectors” circumferentially arranged around the optical axis such that an optical path through the correcting portion of the lens varies as a function of the angular separation from the reference meridian plane, and the correcting portion is divided into at least two sectors having different astigmatism correction axes.

Abstract: An improved ophthalmic lens is disclosed which has a plurality of alternating power zones with a continuously varying power within each zone, as well as in transition from one zone to another. In other words, a plurality of concentric zones (at least two) are provided in which the variation from far to near vision correction is continuous, i.e., from near correction focal power to far correction focal power, then back to near, and again back to far, or vice versa. This change is continuous (progressive), without any abrupt correction changes, or “edges”.
Two versions of the invention are disclosed. In the first version continuous, alternating power variation is accomplished by a continuously changing curvature of the lens posterior surface, thereby altering the angle of impact of light rays on the eye.
Abstract: Compounds, compositions and methods are disclosed useful for enhancing penetration of a pharmacologically active substances across skin or tissue membranes. Compounds for use in such compositions and methods are highly water-soluble N-substituted polyalkylene oxide derivatives of cyclic amides. A compound of the invention has the structural formula:
wherein m is an integer from 2 to about 6, n is an integer from 1 to about 8, and R is hydrogen, trimethylsilyl or lower alkyl.

Abstract: Intraocular lenses include a lens body sized and adapted for placement in a mammalian eye and having a plurality of different optical powers, and a movement assembly joined to the lens body and adapted to cooperate with the mammalian eye to effect accommodating movement of the lens body in the eye. Such intraocular lenses provide enhanced accommodation relative to the accommodation attainable using a single optical power IOL adapted for accommodating movement.

Abstract: An ozone system for agricultural applications generally includes a water flow line having an inlet for receiving a flow of clean water from a water source, an ozone injector suitable for producing a high concentration of ozone in oxygen, preferably from oxygen-enriched air, and a venturi injector for injecting the ozone gas into the water flowing through the flow line to produce an ozonated water stream. The system preferably including a spray assist assembly which provides a stream of gaseous component to assist in dispensing the ozonated water fro agricultural application. The entire system, or at least a substantial portion of the system, is mountable on a motorized vehicle to provide ease in applying the ozonated water stream from the system to agricultural crops, particularly living grapevines.

Abstract: Apparatus and methods for purifying the water in spas or hot tubs are provided. Such apparatus include an ozone generator sized and adapted to purify the water in a spa or jetted tub, the ozone generator including a chip electrode assembly adapted to produce ozone from air using an electric discharge; and a transfer assembly cooperating with said ozone generator to pass ozone produced by the ozone generator to the water in the spa or jetted tub.
Abstract: A portable restraint and confinement device for confining an animal within a fixed boundary. The device includes a base panel which has an outer perimeter defining a fixed boundary. A securement strap is attached at one end to the center of the base panel and at the other end to an attachment device. The attachment device is configured for connecting to a harness, collar or other holding device secured to the animal wherein the animal is confined within the fixed boundary by the securement strap. Alternate configurations of base panel are disclosed for improving portability as well as for use in specific environments and locations. An embodiment is disclosed for use in restraining and confining humans to within a fixed boundary.
