Abstract: Techniques for creating a three dimensional model of an object and eliminate artifacts due to changes in orientation of the object between successive scans. Such techniques may be applied to line scans and slice scans of an object.

Abstract: A method and system for generating a three-dimensional model of a contact lens with a front and a back surface, in which the entire back surface consists of an array of independent data points shaped to conform to three-dimensional data provided by an ocular topographer. The sampling density is sufficiently high to characterize anomalies or injuries anywhere in the eye to optimize comfort and fit. The methods and systems also include modeling a scleral lens which rests either solely on the sclera, or straddles the limbus extending partially into the cornea is described. The resting surface conforms to the topology of the underlying ocular surface with topology guiding the design. Additional methods and systems model scleral lens optics without the use of trial lenses. The lens models can be used to machine or 3D print a lens that fits the patient. Such lenses benefit patients that suffer from dry eyes or whose eyes are not normally dry, but feel dry after wearing conventional contact lenses.

Abstract: The present invention relates to a health care system comprised of a sock aide, a reacher and a shoe horn. The sock aide is removably coupled to the reacher by the engagement of a T-shaped arm on outer surface of the sock aide with a sleeve disposed on one end of the reacher. The sleeves are provided on opposite sides of the reacher to allow the donning of a sock to either the left or right foot. The shoe horn is slidably mounted on the reacher.

Abstract: A flying height tester used to measure the flying height of a head of a hard disk drive. The flying height tester includes a transparent substrate that has an index of refraction greater than 1.5. Utilizing a substrate with an index of refraction no greater than 1.5 improves the flying height sensitivity of the tester.

Abstract: A reacher has a near end with a handle and a trigger. A reacher has a far end. An intermediate extent is provided between the near end and the far end. A sock aide is removably coupled to the reacher adjacent to the far end. A shoe horn is slidably supported on the reacher adjacent to the far end.

Abstract: A golf ball with superior aerodynamic properties is characterized by a progressive depth of dimples on the surface of the ball. The ball surface is divided into a plurality of equal geometries such as triangles, each of which is filled with a plurality of non-overlapping dimples. Groups of dimples are provided in each geometry, the dimples of each group having different depths, respectively. A first group of dimples is arranged about the perimeter of the geometry and a second group of dimples is arranged within the first group. A third group of dimples having a third depth may be provided within the second group, with the depth of the third group being less than the depth of the second group which is less than the depth of the first group. Alternatively, the depth of the third group is greater than the depth of the second group which is greater than the depth of the first group. Similarly, the first and third groups may have the same depth but different from the second group.

Abstract: A bat for baseball and softball with an attachable tip at the exterior end comprising a cylindrical device having a first inboard portion adapted to be held by a player and a second outboard portion adapted to strike a ball upon swinging of the bat, the inboard end and the outboard portion having a common axis; the inboard portion having an enlarged knob at its end with material over the inboard portion from adjacent to the knob to a location at an intermediate extent of the inboard portion; and the outboard portion being formed with a diameter substantially equal to twice the diameter of the inboard portion with a short tapering section therebetween.

Abstract: A digital computer-based degree of freedom (DOF) control system for driving a moving ram of a hydraulic press about a plurality of degrees of freedom as a function of a preestablished motion control program. Actuators responsive to actuator commands drive the moving ram at a plurality of spaced locations. Digital feedback data representative of the positions and loads of the moving ram at the spaced locations are stored in memory. Motion control data representative of the motion control program is also stored in memory. A digital control computer implementing servoloop operations generates the actuator commands as a function of the feedback data and motion control data.

Abstract: A duct jointing system has frame members each with a channel portion for engaging an end of a respective duct wall and an outwardly projecting portion. L-shaped connectors engage in openings in the outwardly projecting portions for securing the frame members together as frames and adjacent frames are connected by cleats engaging projections on the outwardly projecting portions and reinforcing flanges on the connectors, the flanges being cut-away to allow the cleats to be driven longitudinally into position.

Abstract: A means for connecting together sheet metal ducts, e.g. forced air heating ducts, in end-to-end relationship, comprises hollow, roll formed flange members which extend along the edges of adjacent duct ends, and L-shaped corner pieces the limbs of which can be inserted into the ends of the flange members to complete the joint at the corners. A sealing agent or gasket is located between sets of flange members and corner pieces. The flange members have planar side end surfaces for sealing reception of the gasket, and lower protuberances, into which the ends of the metal ducts fit, the protuberances being arranged to bite into the gasket to improve the seal. The corner pieces have laterally offset portions, allowing the raw edge of the duct, at the corners, to project forwardly of the side surface of the corner piece, and hence to bite into the gasket at the corners to improve the seal. Channel shaped cleats are provided to assist in the attachment of pairs of profiles on adjacent end arranged ducts.
