Patent number: 11962715Abstract: Techniques are provided for telephone call information collection and retrieval. A receiver device receives a telephone call from a caller device. The receiver device collects information associated with the telephone call and stores the information in a memory. Subsequently, the receiver device displays, via a graphical user interface, the telephone number of the caller device. The receiver device receives, via the graphical user interface, a user selection of the telephone number of the caller. In response to the user selection, the receiver device displays, via the graphical user interface, the information stored in the memory, including, for example, the start and end times of the telephone call, the location(s) of the receiver device during the telephone call, and text representing the audio of the call (e.g., speech-to-text conversion of at least a portion of the audio).Type: GrantFiled: January 5, 2022Date of Patent: April 16, 2024Assignee: Citrix Systems, Inc.Inventors: Hao Wu, Yu Xin, Jianan Di

Patent number: 11340342Abstract: A high performance, low-cost automotive radar is designed by mounting receivers around a 3D printed Luneburg lens. With this configuration, the antenna radiation pattern is maintained for all angles, (which means no beam deformation). Further, the present radar is capable of performing detection at all azimuth and elevation angles with high angle resolution and broadband operation. The radar adaptively adjusts its spatial sensing pattern, sweeping frequency band, pulse repetition frequency and coherent processing interval according to the environment. This is accomplished by initially performing a rough scan, which updates sensing results via a narrow bandwidth waveform and wide beam scanning. When interested objects are identified, a high-resolution detailed scan is performed in a specific region of interest. In this way, a much more effective detection can be obtained.Type: GrantFiled: August 15, 2017Date of Patent: May 24, 2022Assignee: Arizona Board of Regents on behalf of the University of ArizonaInventors: Hao Xin, Min Liang, Siyang Cao

Patent number: 11303036Abstract: A hollow light-weight, low-cost, and high-performance 3D Luneburg lens structure using partially-metalized thin film, string, threads, fiber or wire base metamaterial to implement the continuously varying relative permittivity profile, characteristic of Luneburg lens structures, is disclosed. The hollow light-weight lens structure is based on the effective medium approach and may be implemented by a number of means. Further, most of the volume of the lens structure is free-space, thus the weight of the lens is significantly less than conventional 3D Luneburg lens structures of the same dimensions.Type: GrantFiled: June 15, 2018Date of Patent: April 12, 2022Assignee: Arizona Board of Regents on Behalf of The University of ArizonaInventors: Hao Xin, Min Liang
