Patent number: 11921229Abstract: An apparatus, including processing unit (PU) cores and computer readable storage devices storing machine instructions for determining a distance between a target object and a radar sensor circuit. The PU cores receive a beat signal generated by the radar sensor circuit and compensate for a phase difference between the received beat signal and a reconstruction of the received beat signal to obtain a phase compensated beat signal. The phase compensated beat signal is then filtered to remove spurious reflections by demodulating the phase compensated beat signal using an estimated frequency of the phase compensated beat signal. The PU cores then apply a low pass filter to the demodulated phase compensated beat signal, resulting in a modified beat signal. The PU cores then determine the distance between the target object and the radar sensor circuit using the modified beat signal.Type: GrantFiled: September 20, 2021Date of Patent: March 5, 2024Assignee: Texas Instruments IncorporatedInventors: Muhammad Zubair Ikram, Adeel Ahmad, Dan Wang, Murtaza Ali

Publication number: 20240028792Abstract: The disclosure provides implicit representations for multi-object 3D shape, 6D pose and size, and appearance optimization, including obtaining shape, 6D pose and size, and appearance codes. Training is employed using shape and appearance priors from an implicit joint differential database. 2D masks are also obtained and are used in an optimization process that utilizes a combined loss minimizing function and an Octree-based coarse-to-fine differentiable optimization to jointly optimize the latest shape, appearance, pose and size, and 2D masks. An object surface is recovered from the latest shape codes to a desired resolution level. The database represents shapes as Signed Distance Fields (SDF), and appearance as Texture Fields (TF).Type: ApplicationFiled: July 19, 2022Publication date: January 25, 2024Applicants: TOYOTA RESEARCH INSTITUTE, INC., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: MUHAMMAD ZUBAIR IRSHAD, Sergey Zakharov, Rares A.

Patent number: 11327166Abstract: In the proposed low complexity technique a hierarchical approach is created. An initial FFT based detection and range estimation gives a coarse range estimate of a group of objects within the Rayleigh limit or with varying sizes resulting from widely varying reflection strengths. For each group of detected peaks, demodulate the input to near DC, filter out other peaks (or other object groups) and decimate the signal to reduce the data size. Then perform super-resolution methods on this limited data size. The resulting distance estimations provide distance relative to the coarse estimation from the FFT processing.Type: GrantFiled: March 27, 2020Date of Patent: May 10, 2022Assignee: Texas Instruments IncorporatedInventors: Murtaza Ali, Dan Wang, Muhammad Zubair Ikram
