Patent number: 7837660Abstract: A flow measurement device 100 is provided that includes an electrode terminal chamber 102 with an inlet 104 in communication with a flow channel 108 for receiving fluid and viscoelastic material aspirated from a surgical site, and an outlet 106 that tapers into a flow channel 108. The outlet 108 has a taper angle that is sufficient to smooth flow and cause viscoelastic material entering the electrode terminal chamber 102 to flow substantially within a center portion of the chamber and through the outlet 106. The electrode terminal chamber 102 further includes first and second electrode terminals 130 and 140 disposed on generally opposite sides of the electrode terminal chamber 102 in a spaced-apart manner. The first and second electrode terminals 130 and 140 are positioned a distance from the center of the chamber 102 that is sufficient to substantially avoid contact between the terminals and viscoelastic materials flowing through the chamber 102.Type: GrantFiled: December 17, 2007Date of Patent: November 23, 2010Inventors: Ross Peter Jones, Mark Ian Lutwyche, David Martin Pooley

Patent number: 7796487Abstract: An apparatus includes a moveable arm for positioning an optical transducer adjacent to a storage medium, a light source, and an elliptical or ellipsoid shaped mirror mounted for reflecting light from the light source to the optical transducer. The elliptical mirror can be positioned on an ellipse, the moveable arm can pivot about an axis passing through a first focus of the ellipse, and the light source can direct light from a point on a second axis passing through a second focus of the ellipse to the elliptical minor. The light source can include a fixed laser and a moveable mirror mounted to pivot about the second axis or a moveable laser mounted to pivot about the second axis. A method performed by the apparatus is also provided.Type: GrantFiled: May 10, 2005Date of Patent: September 14, 2010Assignee: Seagate Technology LLCInventors: Patrick Breckow Chu, Mark Ian Lutwyche, Tim Rausch, William Albert Challener, Thomas Dean Milster

Patent number: 7712360Abstract: An air bubble separator is provided for ophthalmic surgical systems, which includes a housing 102 having a diagonally-oriented flow channel 110 and a vertically-oriented flow channel 130 adjoining the diagonally oriented channel. The diagonally-oriented flow channel 110 has a downstream portion 112 disposed downstream of the vertically-oriented flow channel 130, and an upstream portion 118 disposed upstream of the vertically-oriented flow channel 130. The downstream portion 112 of the diagonally-oriented flow channel 110 has a cross-sectional area 114 that is greater than that of the upstream portion 118. The downstream portion's cross-sectional area 114 is greater than the upstream portion's cross-sectional area 124 by an amount or percentage that is sufficient to slow fluid flow through the diagonally-oriented flow channel 110, so as to cause air within the fluid to rise and flow into the vertically-oriented flow channel 130.Type: GrantFiled: December 13, 2007Date of Patent: May 11, 2010Assignee: Bausch & Lomb IncorporatedInventors: Ross Peter Jones, Mark Ian Lutwyche
