Publication number: 20150312453Abstract: Techniques for switchable camera mirror apparatus are described. In one or more embodiments, a computing device (e.g., a tablet device, a smartphone, and so on) includes a camera functionality that is configured to capture images from a variety of different device perspectives. The camera functionality, for instance, can enable images to be captured from a front-facing device perspective, a rear-facing device perspective, and so on. Included as part of the camera functionality is a switchable mirror apparatus that is switchable to alternately reflect light from different device perspectives, such as to enable images to be captured from at least some of the different device perspectives using a single image sensor.Type: ApplicationFiled: July 6, 2015Publication date: October 29, 2015Inventors: David M. Gaines, Andrew N. Cady

Patent number: 8852541Abstract: Systems and methods for removing impurities from a feed fluid in a single vessel. A method generally includes, in single vessel, contacting a feed fluid passing through the vessel with a copper-based material for removing oxygen from the feed fluid; and contacting the feed fluid passing through the vessel with an adsorbent for removing at least one of water, carbon dioxide, and oxygenated hydrocarbons from the feed fluid.Type: GrantFiled: April 16, 2009Date of Patent: October 7, 2014Assignee: Univation Technologies, LLCInventors: Ronald S. Eisinger, David M. Gaines
