Patent number: 11348252Abstract: Methods for capturing and generating information about objects in a 3D environment that can be used to support augmented reality or virtual reality playback operations in a data efficient manner are described. In various embodiments one or more frames including foreground objects are generated and transmitted with corresponding information that can be used to determine the location where the foreground objects are to be positioned relative to a background for one or more frame times are described. Data efficiency is achieved by specifying different locations for a foreground object for different frame times avoiding in some embodiments the need to transmit an image and depth information defining the same of the foreground for each frame time. The frames can be encoded using a video encoder even though some of the information communicated are not pixel values but alpha blending values, object position information, mesh distortion information, etc.Type: GrantFiled: July 15, 2019Date of Patent: May 31, 2022Assignee: Nevermind Capital LLCInventors: Alan Moss, Krishnaprasad Jagadash, Hector Medina, Fabricio Tofoli, Joel Phillips, Jun Liu, Ramesh Panchagnula, Vassilios Mavros

Publication number: 20060265680Abstract: An improved method, system, and computer program product is disclosed for predicting the geometric model of transistors once manufacturing and lithographic process effects are taken into consideration. This provides a much more accurate approach for modeling transistors since it is the actual expected geometric shapes that are analyzed, rather than an idealized model of the layout that does not accurately correspond to the actual manufactured IC product. The expected geometric shape includes systematic variations, which can be determined based on the layout, and the expected random variations, which can be determined based on the lithographic process.Type: ApplicationFiled: May 19, 2006Publication date: November 23, 2006Inventors: Louis Scheffer, Joel Phillips

Publication number: 20060095236Abstract: Method of forming a reduced model of a circuit. A circuit parameter is selected, and values for the parameter are selected. A circuit or operator equation is solved for the selected value to generate a result. The steps of selecting values and solving the equation are repeated to generate corresponding results. For example, the results may be vectors or columns that are grouped together to form a matrix. For each iteration, a rank revealing factorization is performed on the matrix for use in determining whether a sufficient number of results or vectors have been generated to form the reduced model. After a sufficient number of results or vectors have been generated, a reduced model is formed. The rank revealing factorization may include, for example, singular value, ULV/URV, UTV and RRQR decompositions.Type: ApplicationFiled: September 2, 2004Publication date: May 4, 2006Inventor: Joel Phillips

Publication number: 20060036284Abstract: Devices and methods for sealing a passageway formed by a patent foramen ovale (PFO track) in the heart are provided. One method includes providing an abrading device to the PFO track and abrading the tissue within the PFO track. The abraded tissue forming the PFO track is then held together under pressure, either via lowering right atrial pressure or via applying suction to the septum primum to pull it into apposition against the septum secundum. After a sufficient period of time, the pressure is released and the abraded tissue heals to form a robust seal over the PFO track. Additionally, several devices are provided which can be placed into the PFO track to apply adhesive to the walls of the PFO track. The devices may or may not be left within the PFO track. If the devices are not left within the PFO track, the walls of the PFO track, covered with adhesive, are brought into apposition with one another and adhered together.Type: ApplicationFiled: October 14, 2005Publication date: February 16, 2006Inventors: David Blaeser, Peter Keith, Jerome Grudem, Scott Olson, Steven Hackett, Thomas Ressemann, Joel Phillips, Mark Christianson, Dennis Wahr

Patent number: 6790221Abstract: Methods for making a loaded catheter assembly for delivering a self-expanding stent where the self-expanding stent is carried in a compressed state and the compressed stent has an inside diameter smaller than the outside diameter of the catheter distal tip. The methods can utilize catheter sub-assemblies lacking already attached tips or having partially formed distal tips. A stent can be proximally and co-axially slid over the distal end of the catheter shaft and constrained by a retractable sheath disposed co-axially about the compressed stent. The catheter distal tip can be added or more fully formed after the loading of the stent. Some catheters include a preformed distal conical tip held in position by a heat-shrink film. Other catheters have an elastomeric distal tip waist for slipping over and engaging an outward projection on the catheter shaft distal region. Some catheters are adapted to engage catheter shaft distal threaded regions.Type: GrantFiled: November 7, 2001Date of Patent: September 14, 2004Assignee: SciMed Life Systems, Inc.Inventors: Lance A.
