Patent number: 11529168Abstract: A cannula with a proximally mounted camera and proximally mounted light sources. The lighting sources have beam axes directed distally, toward a workspace at the distal end of the cannula. The light sources are coupled with focusing lenses, to reduce the beam angle of the lighting sources and reduce glare within the cannula tube.Type: GrantFiled: August 23, 2019Date of Patent: December 20, 2022Assignee: Rebound Therapeutics CorporationInventors: Ross Tsukashima, Donald Joseph Fuller, Jack H. Schmidt

Patent number: 10110866Abstract: The embodiments described herein provide scanning laser devices that include an output optic configured to reduce image distortion. Specifically, the output optic is configured to reduce the distortions that could otherwise occur at relatively short projection distances, while also providing good image quality at relatively long projection distances. In general, the output optic includes a prism having a first surface, a second surface, and a third surface. The prism is configured such that the laser light interacts with each of these three surfaces while being transmitted through the prism and outputted to the display surface. The first, second, and third surfaces are each formed to have a freeform rotationally asymmetric shape, and these freeform rotationally asymmetric shapes are configured to work together to correct distortion in projected images.Type: GrantFiled: June 23, 2017Date of Patent: October 23, 2018Assignee: Microvision, Inc.Inventors: Matthieu Saracco, Roeland Collet, Alga Lloyd Nothern, III, Nenad Nestorovic, Jack H.

Patent number: 7708483Abstract: An unbacked transport and conditioning printing system for printing a pattern on a fabric is disclosed. The system includes a fabric characterization and tension control subsystem for gathering information on variations in the fabric and an irregularity detection subsystem for detecting irregularities in the fabric, as well as, crease detection and removal. The fabric passes through a fabric drying and conditioning subsystem for characterization of the fabric. The system also includes a fabric control subsystem for advancing the fabric through a print zone, where a pattern is printed on an unbacked fabric. The fabric is transported through a drying and post-processing subsystem and a closed-loop color control subsystem.Type: GrantFiled: October 21, 2005Date of Patent: May 4, 2010Assignee: Hewlett-Packard Development Company, L.P.Inventors: Mohammad M Samii, Mark A. Van Veen, Jack H Schmidt
