Patent number: 11714275Abstract: A dual phosphor wheel projection system is provided. A first dichroic mirror directs blue light from a first blue laser to a second dichroic mirror which directs the blue light to at least one integrator. The first dichroic mirror directs blue light from a second blue laser to a first phosphor/phosphor wheel, which converts the blue light to longer wavelengths that includes red light. The second dichroic mirror directs the red light to the integrator and transmit others of the longer wavelengths. The integrator combines the red light with red light from a red laser. A third dichroic mirror directs the red light from the red laser to the integrator and directs blue light from a third blue laser to a second phosphor/phosphor wheel, which converts the blue light to respective longer wavelengths that includes green light. The third dichroic mirror transmits the green light to the integrator.Type: GrantFiled: November 25, 2022Date of Patent: August 1, 2023Assignee: CHRISTIE DIGITAL SYSTEMS USA, INC.Inventors: Michael Perkins, Mang Li, Abdul Waheed Salimi

Patent number: 10491904Abstract: Video pixel line buffers are widely used for data processing in video codecs. Video data may be packed into buffers configured to store a plurality of words, each word comprising a series of bits. The video data may be associated with two or more channels. In order to reduce realization costs, data blocks from two different channels may be packed from opposite sides of a word in the buffer in opposite directions. In some embodiments, data blocks from two or more physical channels may be mapped to two or more virtual channels, the virtual channels having balanced data block sizes. The data blocks associated with the virtual channels may then be packed to one or more buffers.Type: GrantFiled: January 18, 2019Date of Patent: November 26, 2019Assignee: QUALCOMM IncorporatedInventors: Shu Lin, Mang Li, Kai Wang, Atul Garg

Patent number: 9628822Abstract: At least one processor is configured to encode samples of a largest coding unit (LCU) of a picture using a sample adaptive offset (SAO) mode. To encode the samples of the LCU using SAO, the at least one processor is configured to: calculate differences between corresponding reconstructed samples of the LCU and original samples of the LCU, clip a number of bits from each of the differences to form clipped differences, sum the clipped differences to form a sum of differences, clip the sum of differences to form a clipped sum of differences, calculate a number of the reconstructed samples, clip a number of bits from the number of reconstructed samples to form a dipped number of samples, and divide the clipped sum of differences by the clipped number of samples to produce an offset for the LCU.Type: GrantFiled: May 9, 2014Date of Patent: April 18, 2017Assignee: QUALCOMM IncorporatedInventors: Athanasios Leontaris, Mang Li, Sumit Mohan, In Suk Chong, Hariharan Ganesh Lalgudi

Patent number: 9188767Abstract: A relay lens system for a high dynamic range projector is provided. The relay lens system comprising: a light input; a light output; one or more lenses configured to relay light from the light input to the light output; and, an aperture stop configured to provide a given numerical aperture to the light being relayed through the one or more lenses, the combination of the given numerical aperture and the one or more lenses are configured to introduce a spherical aberration in the light between the light input and the light output, the spherical aberration changing a shape of a pixel in the light from an approximate square shape at the light input to a function having an upper boundary and a lower boundary based on a distance from a center of the pixel, and a pixel dimension of a dither pattern in the light entering the light input.Type: GrantFiled: November 4, 2013Date of Patent: November 17, 2015Assignee: CHRISTIE DIGITAL SYSTEMS USA, INC.Inventors: Koichi Ito, Mang Li, John Domm, Jerome D.

Patent number: 7613488Abstract: The present invention provides a method for measuring a blood analyte concentration of a body part comprising removing a portion or all of the blood from the body part to produce a modified body part, and recording a first absorbance value of the modified body part. This is followed by filling the body part with blood to produce a filled body part, and recording a second absorbance value of the filled body part. A difference spectrum is obtained by subtracting the first absorbance values from the second absorbance values, and a calibration algorithm for the blood analyte is applied to the difference spectrum, thereby measuring the concentration of the blood analyte. Also provided is an apparatus for determining the concentration of a blood analyte of a body part. The apparatus comprising a chamber of a size and shape to receive the body part, where the chamber comprises an element for withdrawing and reintroducing blood from the body part, when the body part is inserted within the chamber.Type: GrantFiled: December 22, 2003Date of Patent: November 3, 2009Assignee: NIResults Inc.Inventors: George N.
