Publication number: 20180017543Abstract: A nanopore based sequencing system is disclosed. The system includes a plurality of nanopore sensors, each nanopore sensor having a top portion for receiving a fluid. The system further includes an inlet delivering the fluid into the nanopore based sequencing system and an outlet delivering the fluid out of the nanopore based sequencing system. The system includes a fluid chamber that comprises one or more fluid flow channels above top portions of the nanopore sensors; wherein the fluid chamber includes at least one divider that limits the width of the one or more fluid flow channels. In some embodiments, the at least one divider limits the width of the one or more fluid flow channel based on whether the surface tension and adhesive forces between the fluid and the fluid flow channel surfaces are sufficient to prevent the fluid from collapsing within the fluid flow channel.Type: ApplicationFiled: September 8, 2017Publication date: January 18, 2018Inventor: Robert A.

Patent number: 9472005Abstract: A device includes a projection and camera system to create an augmented reality environment in which images are projected onto a scene and user movement within the scene is captured. The projection and camera system have a camera to image scattered IR light from the scene and compute time of flight values used in depth mapping of objects in the room. The system also has a projector to project the images onto the scene. The projected images and scattered IR light use a common optical path through the same lens. Additionally, an illumination system used to illuminate the scene with the IR light may also use the common optical path through the same lens. In one implementation, the projection and camera system are mounted in a movable head of a table lamp.Type: GrantFiled: June 19, 2012Date of Patent: October 18, 2016Assignee: Amazon Technologies, Inc.Inventors: Eric G.
