Patent number: 11428838Abstract: A method of performing single trace inversion to characterize changes in a subsurface region includes obtaining a base seismic trace and a monitor seismic trace of the subsurface region at different respective times. The method includes generating a predicted monitor seismic trace from the base seismic trace by a process including applying a time shift to the base seismic trace, the time shift being derived from estimated velocity perturbations occurring between the base seismic trace and the monitor seismic trace, compensating for amplitude changes between the base seismic trace and the monitor seismic trace, wherein the time shift is applied to the amplitude changes, and minimizing a difference between the predicted monitor seismic trace and the monitor seismic trace by iteratively estimating the velocity perturbations to obtain final estimated velocity perturbations. Changes of at least part of the subsurface region may be characterized using the final estimated velocity perturbations.Type: GrantFiled: April 6, 2020Date of Patent: August 30, 2022Assignee: BP CORPORATION NORTH AMERICA INC.Inventors: Tingting Zhang, Simon Luo, Anar Yusifov

Publication number: 20110091827Abstract: A lighting fixture lighter includes a frame body including a light transmitting window, a flame generator, and an illumination fixture built-in with the lighter for generating illumination light for illumination purpose. The illumination fixture includes a power source, a light source unit supported within a light compartment and aligning with the light transmitting window, and a light button to activate the light source unit for generating an illumination light, so that the illumination light is emitted out of the light transmitting window for illumination purpose. In order to enhance the light intensity of the light source unit, a light reflector is further provided within the light compartment for reflecting the illumination light from the light source unit, such that the lighter not only provides the traditional ignition function, but also provides an added on illumination function in the single compact lighter housing.Type: ApplicationFiled: December 10, 2009Publication date: April 21, 2011Inventor: Simon Luo

Patent number: 7057158Abstract: A high speed interface for optoelectronic devices is disclosed that includes a housing adapted to receive a distal end of a fiber having a slanted end face. The end face of the fiber is optically coupled to an optoelectronic device mounted in the housing. The fiber cladding between the optoelectronic device and the fiber core may be polished or etched to reduce the thickness of the cladding to reduce the separation distance between the optoelectronic device and the slanted end face of the fiber. The reduced separation distance improves the optical coupling efficiency between the end face of the fiber and the optoelectronic device.Type: GrantFiled: June 4, 2002Date of Patent: June 6, 2006Assignee: TriQuint Technology Holding Co.Inventor: Xin Simon Luo

Publication number: 20030010904Abstract: In an exemplary embodiment of the present invention, a high speed optical receiver interface includes a housing adapted to receive a distal end of a fiber having a slanted end face. The slanted end face reflects the received signal along a received optical path. The fiber cladding material along the reflected optical path may be polished or etched to reduce the thickness of the cladding to reduce the separation distance between a photodetector and the slanted end face of the fiber. The reduced separation distance also reduces the beamwidth of the reflected signal that is incident upon the photodetector. An exemplary optical receiver may therefore efficiently couple the incident optical signal onto a photodetector with a reduced active area diameter that is capable of operating at increased data rates.Type: ApplicationFiled: July 12, 2001Publication date: January 16, 2003Inventor: Xin Simon Luo
