Patent number: 10577827Abstract: A modular barrier system enables demountable outdoor rinks—typically for ice hockey, or ice skating, or street hockey. A rink includes multiple panels, each having a factory-attached link. These panels are linearly disposed, adjacent to one another, to form a piecewise continuous boundary wall enclosing a desired area. Attaching one link to the next, typically via insertion of a thumbscrew, connects the panels into a robust assembly. Both straight and curved panels are provided, thereby enabling a rink with round corners. Each panel includes a shell molded from plastic resin, and has a hollow interior which can be filled with water (or other ballast).Type: GrantFiled: March 13, 2019Date of Patent: March 3, 2020Assignee: Lane ResearchInventors: Stephen Kurtin, Scott Winslow, Brian Packard

Patent number: 10394056Abstract: Adjustable focus spectacles using fluid displacement lens units with bipolar membrane distension and a non-circular periphery. The lens unit includes front and rear mounting rings, front and rear distensible membranes respectively mounted on the two mounting rings, a ring shaped flexible seal disposed between the two mounting rings along their peripheries, and front and rear clamping rings for respectively clamping the flexible seal to the front and rear mounting rings. The sealed space defined by the two distensible membranes and the flexible seal is filled with an optical fluid. The two mounting rings are pivotally coupled together at a pivot located along the periphery of the lens unit. A biasing spring is affixed to the front and rear mounting rings at a second location on their periphery to urge them away from each other. An assembly process for the lens unit is also disclosed.Type: GrantFiled: September 30, 2016Date of Patent: August 27, 2019Inventor: Stephen Kurtin

Patent number: 9821216Abstract: A portable ice rink includes a wall formed of multiple wall members linearly disposed adjacent to one another to form a piecewise continuous wall that encloses a desired area, and also includes a chain of links disposed on the outside of the wall members for reinforcement. The rink may further include a waterproof tarp extending underneath the wall members and folded upwards along the outer side of the wall, with its edge tied to the change of links. The tarp can contain water which then freezes to form a skating surface. Curved wall members are provided to form a rink with round corners. Each wall member is a discrete unit, made of molded plastic, and having a hollow interior which can be filled with water (or other ballast). Each wall member is designed with stiffening features to maintain the flatness of its inner surface after filling.Type: GrantFiled: January 23, 2017Date of Patent: November 21, 2017Assignee: LANE RESEARCHInventors: Stephen Kurtin, Scott Winslow, Brian Packard

Patent number: 9804420Abstract: A removable attachment for eyeglasses, where the attachment, when mounted on a parent pair of eyeglasses, substantially completely covers the front and periphery of the parent frame, such that the combination appears to be a pair of dedicated sunglasses instead of ordinary eyeglasses with an attachment. The attachment is held to the parent eyeglasses by magnets. The bridge of the attachment includes ball joints that allow the attachment to fold for storage while not in use.Type: GrantFiled: December 7, 2015Date of Patent: October 31, 2017Assignee: SUNBIRD, LLCInventors: J. David Chute, Stephen Kurtin, Jason Clerk, Deni Crescenzi

Patent number: 9671623Abstract: A removable attachment for eyeglasses. The attachment is held to the parent eyeglasses by magnets. The bridge of the attachment includes ball joints that allow the attachment to fold for storage while not in use, and also allow the lens units of the attachment to twist about a horizontal line with respect to the bridge thereby enabling the lens units to conform to misaligned parent lenses.Type: GrantFiled: November 7, 2016Date of Patent: June 6, 2017Assignee: SunBird, LLCInventors: J. David Chute, Stephen Kurtin, Jason Clerk, Deni Crescenzi

Patent number: 8967797Abstract: Adjustable focus eyeglasses where the range of adjustment can be moved. That is, if a pair of adjustable focus eyeglasses have a range of 0 diopters to 2.75 diopters (to provide a 2.75 D ADD for reading for an emmetrope), this invention could, for example, permit the user to move the range from 0 D to 2.75 D to 2.00 D to 4.75 D so as to accommodate a short term change in the user's distance vision requirement. Each eye can be adjusted independently.Type: GrantFiled: August 27, 2014Date of Patent: March 3, 2015Assignee: Superfocus Holdings LLCInventor: Stephen Kurtin

Patent number: 8888276Abstract: A rotary actuation mechanism for variable focus spectacles is disclosed. The spectacles include two variable focus lens units and a bridge therebetween. The actuation mechanism includes a rotary cam rotatably mounted on the bridge, a fingerwheel attached to the rotary cam to rotate it, a cam follower disposed in slidable contact with the peripheral surface of the rotary cam, and two elongated couplers pivotally mounted on the bridge. The peripheral surface of the rotary cam is spiral shaped to transfer the rotation of the rotary cam into a linear, or pivoting, motion of the cam follower. Each coupler has a proximate end in contact with or attached to the cam follower and a distal end coupled to a linkage anchor of a respective lens unit, to transfer the motion of the cam follower into simultaneous pivoting motions of the linkage anchors thereby adjusting the focal lengths of the lens units.Type: GrantFiled: January 8, 2013Date of Patent: November 18, 2014Assignee: Zoom Focus Eyewear LLCInventors: Stephen Kurtin, Terence J. Villalovos, Daniel E. Fedele, James G. Coates
