Patent number: 6264574Abstract: A game ball is provided for primarily practicing throwing a football in a passing spiral motion to impact a vertical wall, and then via a reactive force, the game ball returns in a passing opposite spiral motion to be caught by the person, who is practicing throwing a football. The body of the game ball has an external appearance looking somewhat like a football, except having only one conical pointed end, referred to as the trailing end, and having the other end, referred to as the leading end, being a substantially planar wall contacting surface. The body is made to absorb a substantial portion of the wall impact energy, and to quickly release a substantial amount of this absorbed energy, which is then directed in the opposite direction, successfully causing the body, serving as the game ball, to return in a passing opposite spiral motion to the locale, where the game ball was initially thrown by a person in a passing spiral motion.Type: GrantFiled: March 20, 1998Date of Patent: July 24, 2001Assignee: Play Visions, Inc.Inventors: Webb T. Nelson, Michael E. McGonigle

Patent number: 6258322Abstract: Specimen preparation apparatus (10) for preparing a specimen smear on a microscope slide (28) includes a single drive shaft in the form of a horizontal screw (17). A smearer chuck assembly (15) threadably engages the screw whereby rotation of the screw causes, due to friction, rotation of the chuck assembly. Respective stop shafts (21, 22) limit the rotational movement of the chuck assembly and consequently when the assembly bears on one or the other of the stop shafts, continued rotation of the screw causes movement of the assembly axially along the screw. In this manner axial and limited rotational movement of the assembly in either direction is controlled by rotation of the screw in either direction and a smearer blade (19) mounted in the assembly may be moved between a smearing station (27), a rinsing station (30), a cleaning station (31) and a drying station (32).Type: GrantFiled: June 23, 1999Date of Patent: July 10, 2001Assignee: Vision Instruments, Inc.Inventor: Peter John Meikle

Patent number: 6255035Abstract: A process for forming T-shaped metal contacts on a dielectric substrate. The process includes deposition of first and second photoresist layers onto a substrate; individually overall electron beam exposure of both layers; with subsequent imagewise UV exposure and development of both layers to form hollow cavities in the layers. By concentrating the electron beam radiation on the mid-point in the thickness of each photoresist layer, the radiation is distributed throughout each layer, resulting in solubility properties which lead to the formation of hollow cavities of a certain desired shape. In one embodiment of the invention, three-dimensional structures are formed in the photoresist layers by filling the hollow cavities with metal. Subsequent removal of unwanted portions of the photoresist layers produces a dielectric substrate having T-shaped metal contacts on its surface.Type: GrantFiled: March 17, 1999Date of Patent: July 3, 2001Assignee: Electron Vision CorporationInventors: Jason P. Minter, John R. Lee

Patent number: 6256089Abstract: A sample cell for imaging a tissue sample includes a base member formed with a pedestal and a base window. A retainer ring is engaged with the pedestal to retain the tissue sample on the pedestal. A housing with a housing window is engageable with the base member to create a fluid chamber and establish an optical path extending through the base window, tissue sample, retainer ring and housing window. A light source directs a first light beam along the optical path to illuminate the tissue sample. Also, an optical detector outside the housing window receives the first light beam after it has be transmitted through the tissue sample. Additionally, the housing has a side window distanced from the optical path and oriented at an angle, &agr;. A second light beam configured as a slit having a length that extends across the breadth of the tissue sample and a width that is approximately equal to the depth of the tissue sample can separately illuminate the tissue sample.Type: GrantFiled: December 16, 1999Date of Patent: July 3, 2001Assignee: Eyetech Vision, Inc.Inventor: Phillip C.

Patent number: 6242065Abstract: A polymeric front optical element blank is provided which may be laminated to a rear optical element blank. The polymeric front blank comprises an optical element having an exterior convex surface and an interior concave surface, with an edge between the exterior convex surface and the interior concave surface. The optical is provided with at least two projections which extend away from and higher than the edge on a side of the optical element having the concave surface. These projections assist in aligning an back optical element during lamination so that the two lenses will not move out of optical registry during lamination, especially where centrifugal forces are used to spread an adhesive between the front and rear lenses. It is preferred that there are at least three projections extending away from and higher than the edge on a side of the optical element having the concave surface.Type: GrantFiled: October 7, 1998Date of Patent: June 5, 2001Assignee: BMC Vision-Ease Lens, Inc.Inventors: Chris Blomberg, Gert Levin, Sujal Bhalakia

Patent number: 6242877Abstract: An apparatus for controlling operation of a processing machine has a computer preferably with a computer aided design program configurable to model a kinematic velocity profile of a point of interest on a machine to be controlled. A graphical user interface on the computer enables an operator to select desired velocity points for a motor drive controlling motion of the point on the machine. A curve fit is applied to the velocity points to realize a desired velocity profile for the motor drive and the point on the machine. The desired velocity profile is then integrated and scaled in order to obtain a scaled velocity profile that realizes an actual, or target displacement of the point as dictated by operation of the machine. By controlling operation of elements of a machine with velocity profiles, coordination of associated elements and points on the machine can be visualized by an operator selecting the velocity points for each drive of the machine. A method for implementing same is also disclosed.Type: GrantFiled: August 25, 1999Date of Patent: June 5, 2001Assignee: The Vision Limited PartnershipInventors: Jere F. Irwin, Gary A.
