Patent number: 9289124Abstract: A tool for calibrating a non-contact tonometer (NCT) comprises a body having a mating feature configured for removably mounting the body on the nosepiece or on the measurement head of the NCT, a pressure sensor carried by the body and arranged to receive an air pulse discharged by the NCT to provide a pressure signal in response to the air pulse, and a radiation emitter carried by the body, wherein the radiation emitter provides a pseudo-applanation event when the pressure signal reaches a predetermined level that is detectable by the NCT as though an actual corneal applanation had taken place. In one embodiment, the mating feature includes a mounting orifice for receiving a portion of the nosepiece. In another embodiment, the mating feature includes a pair of mounting pins sized for receipt by a corresponding pair of mounting holes in the measurement head of the NCT.Type: GrantFiled: July 8, 2014Date of Patent: March 22, 2016Assignee: REICHERT, INC.Inventors: Russell Bonaventura, David G. Kelkenberg, David L. Beverly, Donald E. Miller, David A. Luce

Patent number: 7832992Abstract: An air-cooled multi-stage compression system using centrifugal compressors is disclosed. It is packaged in a comparable volume to a water-cooled unit having the same driver horsepower. The performance is comparable and opportunities for use of the waste heat are available. Existing water-cooled units can be retrofit to run in an air-cooled mode. Special applications such as combined air compression and nitrogen compression useful in air separation applications are presented. The circulating cooling air can make the unit into an air filter of its surrounding space. Cooling air is drawn through the enclosure before being forced through the coolers above. This air movement can cool compressor housings, the control panel and the drive motors mounted in the enclosure.Type: GrantFiled: January 30, 2004Date of Patent: November 16, 2010Assignee: Cameron International CorporationInventors: Robert M.

Patent number: 6666555Abstract: A subjective ophthalmic refractor is improved for operator visibility in a darkened examination room by forming a cylinder axis scale of the refractor as a light-transmitting component having opaque scale gradations and installing a polar array of illumination sources to project light through the cylinder axis scale, which preferably includes a translucent material for diffuse illumination. In an alternative embodiment, the cylinder axis scale includes a photoluminescent material to which the scale gradations are applied. The refractor is further improved by installing respective illumination sources near a cylinder power readout and a sphere power readout of the refractor. The disclosure additionally relates to a method for retrofitting an ophthalmic refractor to illuminate the cylinder axis scale, cylinder power readout, and sphere power readout.Type: GrantFiled: November 9, 2001Date of Patent: December 23, 2003Assignee: Reichert, Inc.Inventors: David Biggins, Douglas H.

Patent number: 5587748Abstract: An alignment override control for effecting automatic vertical alignment of a test axis of an ophthalmic instrument with the center of an eye is disclosed. The test axis is associated with optical alignment means of the instrument vertically movable by an elevation motor controlled by a motor drive. A joystick and a pair of directional switches are connected to the motor drive for manual positioning of the test axis. When the eye comes within a field of view defined by the optical means, the override control disconnects the switches and automatically signals the elevation motor to effect automatic alignment using signal information originating from the optical means.Type: GrantFiled: October 28, 1994Date of Patent: December 24, 1996Assignee: Leica Inc.Inventors: David A.
